Malcolm Merlyn

"I thought of you as a son once, Oliver. I had more in common with you than my own blood, but that's not the reason I'm not going to kill you. Neither is the fact that you are my daughter's brother. The reason you get to live is because death would be a mercy compared to the debt I now owe you!"

- Malcolm to Oliver Queen

Malcolm Merlyn (born c. 2331 as Arthur King) is a male Human in the 24th century who is the father of Thea Queen, Saracon and the late Tommy Merlyn, and the husband of the late Rebecca Merlyn. He was trained by the League of Assassins, taking the name Al Sa-Her ( الساحر Arabic for The Magician). For a period of time, he became the leader of the League, but Nyssa al Ghul took the leadership from him after Oliver Queen defeated him on behalf of Nyssa.

Malcolm is a formerly successful businessman who was CEO of Merlyn Global Group, and was a prominent figure in Starling City. Fueled by the death of his wife during a mugging in the crime-infested area of "The Glades", he secretly plotted "The Undertaking". After The Hood began to intervene in his plot Malcolm donned his league uniform and became the Dark Archer, an assassin who defeated the Hood twice in combat. He eventually succeeded in his plan, though only partially, but was believed dead when Oliver struck an arrow through his heart.

He eventually revealed himself to be alive to Moira when he discovered he was Thea's biological father and he sought redemption with her. Instead, Moira revealed to the League of Assassins that Malcolm was in fact alive. After some time, he was no longer hunted, due to Oliver helping to wipe out his blood debt. He later became an uneasy ally of Team Arrow, despite their constant qualms. After Oliver defeated "Ra's", he gave Ra's ring to Malcolm, making him the new Ra's al Ghul. However, Nyssa soon took power and disbanded the League, and this power struggle cost Malcolm his left hand. In his anger for Oliver, he joined forces with Damien Darhk, whom he originally fought with as a temporary Green Arrow. However, after the destruction of Tevat Noah and Darhk´s growing insanity after the death of his wife leading him to decide to destroy the world regardless of the existence of a safe haven, Malcolm defected from H.I.V.E. and joined forces with Team Arrow again. Malcolm currently aids time traveler Eobard Thawne/Reverse-Flash and Damien Darhk in a quest to locate the Spear of Destiny, in exchange for Eobard changing his past and gaining a better life in the process, including the revival of his son, Tommy and his wife, Rebecca.

Early life
Arthur King was born sometime around or before 2331.

As a member of The Hidden
Arthur was recruited by The Hidden, initially believing it to be a modern-day crusade. He developed a romance with another member, Lourdes, despite her being betrothed to another man. Due to this, their leader Ibadan sent Arthur and Darius out on a mission in the Hindu Kush mountains to retrieve a stone marker, in order to prevent tribal wars. However, only five miles from the camp, they were forced to duck behind their Jeep to protect themselves from a sandstorm. Once the sandstorm cleared, they noticed the League of Assassins approaching by horseback in the distance.

Sometime after, Arthur legally changed his named to Malcolm Merlyn for unknown reasons.

Living in Starling City
Eventually, Malcolm fell in love with a woman named Rebecca. In 2350, Rebecca gave birth to a son, Tommy.

In 2366, his wife was murdered in the Glades section of Starling City. Earlier, Rebecca tried to call Malcolm for help, but he was busy and turned his desktop monitor off, unaware of the nature of Rebecca's call. Later, after Malcolm turned it back on, he received a call from a businessman who he negotiated with until he was done, then Tommy woke up in a nightmare. Malcolm comforted him, performing a vanishing coin trick, and promised he wouldn't leave or let anything happen to him but then two SCIS officers, including a friend of his, showed up at his door step to inform him Rebecca had been murdered. After the death of his wife, Malcolm had a brief affair with Moira in his grief who was deliberately cheating on Robert out of spite with his best friend but Malcolm felt immense guilt for betraying Rebecca's memory. However this encounter would result in the birth of their daughter Thea, though Malcolm would be unaware of this for almost 20 years. After the funeral Malcolm sat at Rebecca's burial spot for hours after the event until his SCIS friend gave him information on the killer. He later tracked him down, pretending to be lost, and pulled a gun on him trying to understand his motives and scolding him for his pain. However, the punk fought back and severely beat Malcolm, but as he walked off Malcolm fatally shot him in the back and killed him. Malcolm heard of Nanda Parbat, a place to deal with his pain and despite the insistence of his SCIS friend, Malcolm was set on leaving and explained to Tommy that he would return. He found his way to Nanda Parbat and was brought before an 8 year old Nyssa al Ghul, member of the League of Assassins, while she trained but she immediately believed him to be the League's next victim, but Malcolm clarified and told her he wasn't there to fight her but to train. As Nyssa demanding explanation Malcolm performed the same coin trick on her and impressed her, she gave him a new name for the League, "Al Sa-Her" (The Magician).

He served with them for two years and was trained by Al-Owal under supervision of the League's leader Ra's al Ghul, who guided him and helped him see the world for how cruel it truly was, helping him find purpose. He was trained in all manner of combat, including the ability to withstand immense pain. After training and serving with them for two years, he became the first person to ever be released, on condition that he follow the League's codes. As a result of his time with them, Malcolm also became more calculating.

After returning to Starling City, he then gathered with various people including his best friend, Robert Queen and Frank Chen and started a plan to rebuild the Glades and free it of crime, first by forcing criminals to give up their wealth and give it to the needy, keeping their names on a list. However Malcolm was estranged from Tommy and took little involvement in his upbringing leading Tommy to believe he cared for no one but himself, spending most of his time at Oliver's house where he saw Oliver's father Robert as a surrogate father figure. Despite this however Malcolm did bail Tommy out when he got into trouble with authorities.

In late 2373, Malcolm meets with various associates dedicated to fixing the Glades of crime, these included Robert and Frank. Malcolm told them of his plan to level the Glades using an Earthquake device made by Dr. Markov at Unidac Industries. Though some were persuaded, Robert was wary of Malcolm intentions. Later, after everyone had left, Robert met with Malcolm to question his plan where Malcolm revealed the unthinkable circumstances of his wife's death to Robert. Later, Malcolm had Frank rig Robert's boat with explosives to kill him to keep his plan in motion. This would inadvertently cause the eventual creation of Oliver Queen and Sara Lance's respective vigilante identities "The Arrow" and "The Canary". After the boat was sunk and Robert was dead, Malcolm continued his plan and used the criminals on the list to instead buy sections of the Glades and hired other criminals and mercenary's to complete his mission. He also had Moira approve all scientific developments through Queen Consolidated and sub companies Tempest and Unidac Industries. He also had Moira personally visit anyone working in the Glades who had plans that would endanger the Undertaking, all of this while using her own life and Thea's as a threat to keep her in line.

In 2376, Tommy used Malcolm's shuttle without his permission to head to China to search for Oliver acting on a tip that he may still be alive, and Malcolm yelled at Tommy on the screen for taking his shuttle without his consent before Tommy hung up on him.

The Undertaking
Moira meets with Malcolm, informing him that Oliver knew nothing of his father's involvement in the plan or that the Queen's Gambit was sabotaged, before he looked in his own version of the list. Malcolm is seen for the first time in person and met with Moira to discuss The Hood. He expressed that he was uneasy about him. At first Moira expected this was because he had a large amount of wealth, but he replied that it was because the Hood was targeting "The List". When Oliver was accused of being the vigilante Malcolm later invited Moira to talk with him upon short notice. They discuss whether Oliver might actually be The Hood, and he holds up his end of the argument that he strongly believes that Oliver is due to the suspicious timing and explainable absences, along with numerous officials submitting hard evidence. After this, he sends a man to kill Oliver based on his assumption but he failed when Detective Lance killed him. After the chaos cleared, Moira went to consult with him. Moira threatened to ruin his life if he ever tried to hurt the Queen family again. Though Malcolm listened he still appeared to have his suspicions.

When Moira was almost shot and hospitalized Malcolm visited her during this time, much to her distaste. He offered her friendship as they previously had, but she was hesitant. Later, his son Tommy came asking why his father cancelled his credit card while the elder was practicing fencing. Malcolm replied that he had permanently cut Tommy off from his trust fund and the family because he had grown tired of Tommy's constant laid back attitude which had grown tiresome. Tommy then argued with his father that it was his trust fund which Malcolm further reminded him is comprised of his money, before resumed his fencing.

Tired of the Hood's interference, Malcolm took up his own vigilante persona, the "Dark Archer", and killed Adam Hunt to lure him out before attending a party at the Queen Mansion where the Hood was the topic of discussion and the killing of Adam Hunt. Malcolm also appeared to still have suspicions as he asked Oliver a few questions of the Hood and his nickname, even suggesting "Green Arrow", and looked at him with suspicion when he left the room the same time as the cops after they reported Hunt's murder to party attendee Commissioner Nudocerdo. Later Dark Archer killed Nelson Ravich to again lure out the Hood and set up a trap in a warehouse which failed, then Malcolm was informed that Walter had more information on the list and consulted with Moira about the predicament and stated that action needed to be taken. Desperate to lure the Hood out, Dark Archer took hostages in a factory and fought him but Dark Archer came out on top, informing Hood that he knew he was targeting the list, and almost killed him but the Hood managed to get away. Malcolm later had Walter abducted and informed Moira that he wouldn't be harmed and would be safe until the Undertaking was over. Oliver's defeat at the hands of Dark Archer gave him nightmares and scared him so much that he refused to suit up again fearing for leaving his family should he be killed. However Diggle was finally able to snap him out of his fear before Oliver became Hood once again.

Malcolm invited his son and Laurel to have dinner with him. At dinner, Malcolm quite openly mentioned to Laurel how his wife was killed, though not before trying to getting Tommy to sign over his mother's clinic, so it could be shut down. Tommy then felt betrayed again and stormed off as Laurel directly confronted Malcolm about the cut off but he told Laurel that he needs it to be stronger just like he was forced to after his wife's death. Malcolm also met with Moira to discus Carl Ballard's endangerment to the Undertaking and she agreed to handle him but demanded proof of Walter's survival first. Malcolm later came to Moira at Thea's birthday party to give her a photo of him and gave her a re-assuring touch on her shoulder, unaware Thea was watching who believed them to be having an affair. Moira met with Malcolm to inform him Carl won't be a problem anymore but Malcolm then reveals that he learned from Walter that Moira had the Queen's Gambit salvaged and orders Moira to destroy it, unaware that Diggle is spying on them in the other room. However Malcolm appeared to have voice amplifiers in the room as when Oliver and Dig played it again Malcolm's voice was cloaked.

Without knowing Moira, tired of being used, hired China White to assassinate Malcolm. Malcolm visited Tommy at Laurel's apartment on his 28th birthday and invited him to an awards ceremony where he was to receive the humanitarian award but Tommy refused. Later though Tommy did attended, albeit reluctant. Frank Pike read out Malcolm's award announcement before handing it to him before Malcolm gave a speech his philanthropy and charitable nature to making Starling City better, but noting that he hasn't done enough but one day he will. As he was giving his speech, the lights were turned off by the Chinese Triad. Malcolm quickly exited and found Tommy, and the two made it up to his office. Malcolm explained to Tommy about his safe room, and proceeded to open the door to it. However, before he could admit to his son his alter ego of the Dark Archer, Malcolm was shot from afar by Deadshot, who had been assigned to his assassination. Before Malcolm could die, The Hood arrived and was able to convince Tommy to give his father a blood transfusion, in order to rid his body of curare poison laced in the bullet. He woke up in a hospital bed some time later and talked to Tommy and confessed his guilt for letting him down as a child. Moira visited, and Malcolm asked her to find his would-be killer, unaware it was actually Moira.

Malcolm began a vengeance mission to find who was responsible for paying Deadshot to kill him and met with a member of the Chinese Triad to find out, promising him a reduced prison sentence. Moira with no choice pinned the blame on Frank Chen and gave evidence that he was the one who ordered the kill. Dark Archer later killed Frank as he met with Moira and wanted to kill his daughter but Moira begged Dark Archer not to which Dark Archer agreed. After quitting his job at Verdant, Tommy visited his father at Merlyn Global Group and asked for a job.

Malcolm received word that the Markov device is ready and celebrates with Moira in honor of Robert and Rebecca. Later Moira storms into a meeting Malcolm has with his Chinese employers about Walter apparently being killed but Malcolm shows her that he is alive, unaware that the Hood is listening in. Later when Walter was rescued by the Hood, Malcolm talked to Oliver about Walter if he knew anything but he didn't and told Malcolm that those who nabbed him would pay. To tie up loose ends Malcolm, as Dark Archer, visited Unidac Industries and eliminated Dr. Markov and his team, including two innocent young scientists for being witnesses, before destroying the labs to eliminate evidence before speeding off in his car. The following day, Malcolm ran in to Oliver in his company's building, while Felicity Smoak attempted to hack the system. Later, when Malcolm realized that Felicity has hacked into his system, he removed the device and had it hidden. Malcolm later paid Walter a visit at the Queen Mansion until Moira returned and accused Malcolm of wanting to kill him to tie up more loose ends, given Dark Archer's massacre earlier, which Malcolm admitted was true. Later Diggle found the device's empty container while Malcolm was personally visited by The Hood. The vigilante attempted to shoot Malcolm with an arrow, but Malcolm caught the arrow before revealing to him that he is the Dark Archer, also noting the irony of Malcolm trying to kill him at Christmas, Hood saving Malcolm a few months before and now Hood trying to kill him. The two of them engaged in hand-to-hand combat, Malcolm ultimately coming out the victor, knocking Hood out. He lifted his hood and discovered his true identity - Oliver Queen.

Malcolm had Oliver tied up before he could regain consciousness. Oliver was awoken, and Malcolm explained to him why he had done what he had before leaving, awaiting the destruction of the Glades. Later Tommy visited Malcolm to tell him that Laurel and he were over and that Oliver believed he wanted to destroy the Glades but Malcolm confirmed it much to his shock. Malcolm then played a recording of Rebecca's death to Tommy before violently yelling at him "They deserve to die! All of them!" However then Moira confessed the plan on TV and three cops arrived but Malcolm easily dispatched them and Tommy tried to kill him but Malcolm knocked him out. After this he waited, geared up in his safe room, and The Hood and John soon found him. Dark Archer fought them both simultaneously, despite being on the losing end. He threw a throwing knife at John and managed to escape to the roof. Hood and Dark Archer squared off on the roof, shooting arrows at each other, before engaging in hand-to-hand combat. He managed to get Hood in a choke hold, telling him that he would soon be joined by his mother and sister in death, remembering the last words of his his father Oliver managed to stab Malcolm through the chest with one of Malcolm's arrows, by stabbing himself through his shoulder. Oliver rose from the ground, and after receiving confirmation from Felicity that the device was disarmed, told Malcolm that his plan had failed. Injured, Malcolm revealed he had a second device stationed in the Glades. Believing he had won, Malcolm fell on his side and succumbed to his apparent demise.

Despite everyone's assumptions, Malcolm had in fact survived his brush with death; he had coroners make the police believe he was dead and had left Starling City. However he still had associates in the D.A.'s office including someone close to A.D.A. Adam Donner. The League also learned of his Undertaking which violated their codes but believing Oliver to have killed him they considered the matter settled.

Pursued by the League
5 months following his apparent death, it is now public knowledge that Malcolm was responsible for the Undertaking and he was the Dark Archer. When Al-Owal attacked Oliver looking for Sara Lance, Oliver discovered Merlyn's history with the League of Assassins. When Moira was in danger of being prosecuted Malcolm returned to Starling and used "a little persuasion" to make sure she was acquitted of the charges of being associates with him. After she was acquitted, her driver brought Moira to a remote location where Malcolm was waiting, killed the driver and revealed himself to Moira. Using resources in Starling Malcolm followed Donner's investigation of links between Moira and Malcolm and became suspicions she had kept secrets even from him. A genetics test confirmed his suspicions - Thea is his daughter. Malcolm continues to privately confront Moira at the Queen household and even revealed the guilt he had towards inadvertently killing Tommy and insisting that she owes her life to him after acquitting her. Determined to play a part in his daughter's life, Malcolm demands that Moira tell Thea of her true parentage. Moira refuses and contacts Ra's al Ghul, informing him that Malcolm is alive. She reveals this to Malcolm, advising that he run since Ra's wanted to kill him personally which he did but said the matter wasn't settled.

Felicity discovered Merlyn's secret and told it to Oliver which made him distant from Moira. When Thea was kidnapped by Slade Wilson, Moira quickly suspects Malcolm's involvement. However, despite her fear for her daughter's life, she does not reveal her suspicions to Oliver or to the SCIS. Thea is also told by Slade that Malcolm is her biological father. Thea became distant once she knew Malcolm was her father and starts calling herself "Thea Merlyn". In a shuttle trip back home Moira, trying to make things right with Thea and Oliver was about to confess that Malcolm was alive but was hit by Slade's ship and killed before she could say anything. When Malcolm heard what happened to Moira he made his way back to Starling City to check up on Thea.

Dark Archer arrives just as Slade's Mirakuru army lays siege on the city, just in time to save Thea from being killed by one of the henchmen and reveals himself to her before killing him. Thea, out of shock and panic, ran away into the subways before Malcolm catches up to her, insisting he wasn't going to hurt her begging her to come with him to safety but she refuses before being attacked by another minion. After he manages to kill him, he temporarily loses consciousness, and when he comes to, Thea is pointing a gun at him. Malcolm tells Thea that he understands her pain as he has endured it too - with Rebecca and Tommy's deaths - just as Thea did with her loss of Moira and Robert. Suddenly Thea fires two shots in his direction. As Thea feels guilt ridden for killing her real father, Malcolm comes to and reveals that he was wearing a kevlar vest. Malcolm, to Thea's disgust, told Thea that she had more nerve than Tommy. When Thea left to find Roy, Malcolm compared Roy to Moira and Oliver: they were all liars. Later, after Thea found out Roy's identity as The Arrow's accomplice, she went back to Malcolm, waiting in his shuttle. She requested that he teach her how to suppress her emotions, as she never wanted to feel the same way again, and they soon departed from Starling City.

War with League of Assassins
Following them leaving Starling City, Malcolm and Thea left for Corto Maltese. The two took up residence in a mansion owned by Malcolm. He decided to train her by pouring boiling water on to her hand, to teach her that "pain is inevitable, but suffering is optional". However, she was unable to stand it, and Malcolm decided that he had to train her the same way he had been trained, by physically hurting her to the point that Thea retaliated, pointing a sword, allowing him to determine that he training had began. During this period he trained her in martial arts, swordfighting, stealth and archery. Somewhere during this period he drugged her with a plant votura that made her follow orders without remembering it. He and Thea took a plane to Starling City where he made her kill Sara Lance on a rooftop by shooting three arrows in her chest. The two then flew back to Corto Maltese where they kept training while Thea did not realized about what had happened.

After 6 months, Malcolm saw his daughter able to take down multiple trainers and congratulated her. When Oliver arrived looking for Thea and arrives at the mansion Malcolm readied his bow but Oliver was called off. Malcolm later spied on Thea as she talked to Roy. Thea later requested to head home and proved her training's worth by fighting Malcolm with swords and disarmed him, but Thea implied that he let her win. Malcolm returned to Starling City after Thea in order to watch over and protect her. He also bought shares for Verdantand the nearby foundry (the Arrowcave) to help Thea put it back in business, which makes Malcolm the owner of Oliver's base. Nyssa also informed Oliver of Merlyn's survival after believing him to be Sara's killer. After following leads Nyssa tracks Malcolm and fights him and Oliver tags him with an arrow but doesn't kill him much to Laurel and Nyssa's anger. Malcolm later privately contacts Oliver and pleads his innocence in Sara's death knowing that killing her would only provoke Nyssa and Ra's and Oliver believes him. Laurel however begs Nyssa to kill Malcolm at any cost but she kidnaps Thea to lure him out where Dark Archer, Arrow and Nyssa fight each other and Dark Archer manages to defeat Nyssa but Arrow holds an arrow to him. Malcolm admits his high body count but protests that he didn't kill Sara and Arrow contemplated killing him for his past crimes but was unable to due to his vow and let him go and proclaimed Malcolm to be under his protection until Sara's true killer was found. Later Malcolm contacted Thea to tell her that he would protect her at any cost.

Malcolm continues to train Thea without Oliver's knowledge and allows her access to his wealth so that she could buy herself an apartment while rebuilding the club, much to Oliver's chagrin. He later spied on Thea and saw Oliver at her apartment, much to his annoyance. Malcolm was later contacted by Thea after Oliver visited her loft as the Arrow to find out if she was responsible for Sara's murder, he later confronted Oliver inVerdant and after being attacked, he revealed that he had Thea kill Sara through a plant called votura which thrives in Corto Maltese which was used to erase her memory of the incident. His whole plan was to make Ra's al Ghul focus on the killer and force Oliver to confront Ra's as he did not want to put Thea in danger, his aim that Oliver would kill Ra's al Ghul so he would no longer be hunted by the League.

Malcolm continued to train Thea in her apartment but she expressed worry over Oliver for not calling as it had been days since he did so, but he promised her to look into it as he regarded Oliver as family. Malcolm then visited Felicity, Diggle and Roy in the Arrowcave to ask them if they'd seen Oliver which they denied and Malcolm suspected Oliver's death at Ra's hands. Malcolm then visited the site where Oliver and Ra's had dueled but only found a sword with Oliver's blood and returned to Starling in the Arrowcave to inform the team of the news and present the sword. Though Malcolm offered his condolences but Feliciy and Diggle scolded Merlyn for getting Oliver killed. Malcolm then arrived in Thea's apartment where she threw a letter opener at him (which he caught). He informed her they were leaving Starling forever, but decided not to reveal her brother's fate to her.

He later visited her at her apartment expecting her to be packing. However she was gone and he found her at Verdant. He asked her why she was not packing and she told him he did not explained why they had to leave, and said she wasn't leaving unless he told her why. He later went to her apartment were Roy confronted him who told him to stay away from Thea and said he would not allow Thea to go with him. Roy also scolded him for manipulating her into killing Sara and told Malcolm he would lose her forever, but Malcolm told him it was a family matter, and he wasn't family. Malcolm later met her at her apartment and apologized to her, and told her the truth. He explained Ra's wants to kill him and his family for the undertaking, but later Thea told Malcolm they weren't leaving and told him not to be afraid of Ra's just like he taught her not to be and to face Ra's together. Malcolm agreed and they decided to stay.

Malcolm continued to train Thea using even more brutal methods and insisted that she needed to be willing to kill in order to beat Ra's but she asked how he is so willing to kill, and he told her that it started when he killed the man who murdered Rebecca. Later Malcolm spied on Team Arrow in the cave, via hacked webcam, and learned that Danny Brickwell/Brick killed Rebecca. As Arsenal and Black Canary pursued Brick into a police precinct Dark Archer followed and arrived in time to save them from Brick executing them as Dark Archer stated he needed to talk. In the Arrowcave Malcolm proposed an alliance with Team Arrow, as they have the same enemy. Laurel and Roy, despite still resenting Malcolm, where willing to consider but Felicity and Diggle were not and declined Merlyn's offer. Later Malcolm prepared to kill Brick himself despite Thea begging him not to trying to see a goodness inside. As the people of the Glades fought back against Brick's army, forcing Brick to flee, Brick ran into Dark Archer again in the ally and was easily subdued by Dark Archer who revealed his identity and prepared to kill him. Brick revealed that he murdered Rebecca not just to join a gang but because she was weak angering Malcolm more but before he could pull the trigger Arrow, very much alive, arrived and begged him to spare him for Thea's sake. Malcolm was persuaded and spared Brick so he would face court justice. As Malcolm told Thea the new choice he made Oliver walked in and was ok with Malcolm's presence, despite Thea being aware of their distaste for each other. Though Oliver admitted to Malcolm that he still despised him for having Sara killed and committing the undertaking, he asked Malcolm to train him to face Ra's al Ghul.

A week later Malcolm visited Team Arrow and told Oliver if they were to survive he needed to tell Thea the truth, though Oliver believed telling her would shatter their relationship forever. Malcolm visited Thea at her apartment after Oliver told her the truth but she became distrusting of him for not telling her and left, determined to avoid the issue of Ra's al Ghul. Later when Chase, a League agent, ambushed Thea in an attempt to assassinate her Dark Archer and Arsenal arrived to stop him as he committed suicide with cyanide. As Oliver arrived to see what happened Malcolm, despite knowing Thea's new found scorn for him, informed them that to be Ra's they needed to purge their fear and the only place on Earth capable of doing that was Lian Yu. Unbeknownst to either Malcolm visited Lian Yu and freed Slade Wilson promising him to chance to escape via the plane Oliver and Thea used.

After learning the Slade escaped Oliver called Malcolm who admitted his actions and informed him Slade's release is a test to help him regain his killer instinct and disabled their cellphones. After Oliver and Thea narrowly escaped Slade on the island and returned home, they confronted Malcolm about his actions and when Malcolm insisted his actions were out of love, Thea scorned him for making her kill Sara. Malcolm was highly enraged that Oliver told her and she insisted that though she was still Malcolm's student she was no longer his daughter highly irritating him.

He started training Thea and Oliver in sword fighting. He easily beat both of them at once in a practice fight as he stressed the importance of fighting in unison. Thea remarked that it is his fault the League is after them. John tells them that the club is now highly secured and Malcolm told Oliver it might be wise for him and Thea to stay here. He explained that the only reason the League has not killed him is that they do not know where to find him. Oliver says they will stay at the loft, after which Malcolm says they clearly have their stubbornness from their mom. Malcolm later got followed as he realized it is Laurel. Laurel attacked him, but he easily fended her off. He says she has an identity crisis and that she could never beat him with just a stick. A furious Laurel pulled a gun on him and Malcolm said he will find out if she is a truly a killer. Suddenly they got surrounded by assassins who disarmed Laurel and held her back. Nyssa told Laurel to stand back and Malcolm engaged her in single combat. After a short fight, Nyssa quickly overpowered him and knocked him out. Malcolm gets tied up and brought to a chopper as Nyssa tells him he will face torture for what he did. Malcolm told her that he would only be punished for the Undertaking and that she will never succeed her father after her relationship with Sara. Oliver attacked them and Nyssa fights him while Malcolm gets dragged to the chopper. Malcolm attempted to fight back, but got pulled in the chopper and flew away. Nyssa was defeated by Oliver and did not make it back to Nanda Parbat. He later gets brought before Ra's Al Ghul who told him about how he once met an amazing magician who was a shade of himself as he met him nearly 25 years later. Ra's said magicians can cheat many things, but not death. Malcolm begged him for mercy to which Ra's replied that he should die at least with some dignity. A screaming Malcolm got dragged away to be tortured. Barely conscious after the torture, Malcolm gets hanged above a fire. He woke up as Oliver and Diggle came to save him. He tried to tell them it was a trap, but Ra's quickly captured them.

Following Ra's death at the hands of OIiver Queen and the doom of his Omega Virus, Malcolm became the new Ra's al Ghul and leader of the League.

As Ra's al Ghul
Thea and Laurel travel to Nanda Parbat to find a cure against Thea's bloodlust. Malcolm tells her that the bloodlust can be held at bay for a time by murder, but ultimately Thea needs to kill the one who almost murdered her, to be freed from the bloodlust for good. As Ra's al Ghul has already died, this is impossible. Malcolm then sends two of his men to Thea's bedrooms, to have her kill them. This keeps Thea's bloodlust at bay for a few months. Also, after previously having denied the request, Malcolm allows Laurel to revive Sarah in the Lazarus Pit. Furiously, Nyssa destroys the Lazarus Pit as she thinks Malcolm is misusing it. For this, Nyssa is imprisoned by Malcolm.

Legends of Yesterday
Malcolm has rather uncertain motives. While "Team Arrow" and the Flash were in Star City facing Vandal Savage (who was trying to kill Kendra Saunders/Hawkgirl), Malcolm and several members of the League appeared at the Arrowcave to let his friends know what they're dealing with; he proceeds to explain that Savage is immortal and was associated with Genghis Khan and Julius Ceaser's plots during history and that no way to stop him is known to mankind. After having captured Carter Hall and interrogated him, Malcolm appears and reveals to the heroes and says that Savage has left Star City and is after the Staff of Horus, an item he has used throughout history to kill Hawkman and Hawkgirl's previous incarnations throughout history. Savage escapes and Malcolm arranges a meeting between him, Oliver and Barry Allen/Flash to talk of a truce, since negotiation would be the right way to handle this. Savage wants Kendra and Carter handed over and says that he will destroy Star City and Central City if he doesn't get what he wants; Malcolm claims that handing over the two will be the right choice, but he couldn't stop the Arrow and Flash from destroying Savage using the Staff of Horus, turning him into a pile of ashes. Malcolm returns to the location shortly after and gathers up the ashes; what he plans to do with them is unknown, but some believe he wants to bring Savage back to life.

Malcolm returns to Star City once again to save his daughter when Thea, Felicity and Diggle have been captured by Damien Darhk. When Oliver gives himself up to Darhk, Laurel and Malcolm, who is disguised as the Green Arrow, attack Darhk and H.I.V.E: and are able to save the captives. While Laurel brings her weakened friends to safety, Oliver and Malcolm fight Darhk together and overpower him, blowing up the entire building and almost killing Darhk.

Losing the League
When Thea, weakened by not answering her bloodlust, seems to be dying, Nyssa, who has fled her prison, approaches Oliver, promising him a cure for Thea under the condition that Oliver kills Malcolm. Determined not to kill Malcolm, Oliver manages to convinve Merlyn to step down as Ra's and hand the ring to Nyssa. Simultaneously, Laurel talks to Nyssa and Nyssa accepts these conditions. However, when both meet, Malcolm has Nyssa attacked by Assassins. Nyssa escapes. This results in a civil war fought in the streets of Star City, with mostly innocent civilians dying in the crossfire. To end this, Oliver proposes that Nyssa and Malcolm end their feud in the traditional way - a duel to the death.

Both accept, but when the fight is about to begin, Oliver states that he will fight Malcolm instead of his wife, as is his right. Nyssa furiously refuses to let someone else fight her battles for her, but Oliver tells her that if he has to chose between the death of Nyssa or Malcolm, he would definitely choose Malcolm. Malcolm and Oliver then battle and eventually, Malcolm is overpowered. With his opponent on the ground, Oliver tells Malcolm to yield, but Malcolm states that Oliver has to kill him. To prevent having to kill Malcolm, Oliver merely cuts off Malcolm's hand. While Malcolm passes out Oliver hands the ring to Nyssa, making her the leader of the League of Assassins.

Now forced to obey Nyssa, Malcolm arrives when she later summons her and Oliver Queen. When Nyssa thanks both for coming, Malcolm remarks that he did not have a choice. Both Oliver and Malcolm are surprised, when Nyssa takes off the ring and throws it into the fire, claiming that she earlier disbanded the League and released its assassins. Nyssa then leaves, leaving Malcolm and Oliver behind. Malcolm then turns to Oliver, claiming that the only reason that he won't kill Oliver is because death would be a mercy compared to the debt Malcolm now owes him.

To make Oliver suffer, Malcolm meets with Damien Darhk later, revealing to Damien the identity of Oliver's son William, the person Oliver loves most.

Betraying Oliver
When Thea's health begun to take a turn for the worse Malcolm returned to Star City and explained to a confused Oliver that because she has resisted the bloodlust, it is beginning to kill her instead. And unlike Sara whose soul was restored by John Constantine, Thea's is still incomplete and if she doesn't indulge it she will die but Thea regardlessly insists that she won't and it's her choice to make. Later when Oliver returned he thanked Malcolm for taking care of her while he was busy but Thea's health takes a darker turn and is hospitalized. Oliver later approaches Malcolm and informs him that Nyssa has obtained the Lotus from Tatsu, and that it can heal her but only if Oliver kills him or if Malcolm surrenders his ring. However Malcolm isn't convinced but after Laurel obtains a sample of it from Nyssa and Malcolm sees the effects himself, he agrees to Nyssa's terms.

However at the meeting Malcolm double crosses Nyssa and instead arrives with an army of league members, just as Nyssa also does and both sides of the league begin fighting each other in a fight that leads onto the streets and sees several bystanders killed in the crossfire. Later Malcolm returns to the Arrowcave to say goodbye to Thea and remarks to Oliver of the first time he met her when she was 4 months old, and how he always sensed a deeper connection to her. With no options left Oliver suggested an option where Malcolm could keep the ring and obtain the Lotus and suggested he challenge Nyssa to a trial by combat. At the location of their fight however before they could begin Oliver stepped in and volunteered to take Nyssa's place, which she agreed to. Oliver and Malcolm then fought but after a brief but intense fight Oliver subdued him and demanded her hand over the ring but Malcolm insisted that he'd have to kill him. But Oliver instead cut Malcolm's hand off and gave the ring to Nyssa. After getting his amputation healed Malcolm visited Nyssa, now Ra's al Ghul, at her request but she took off the ring and threw it into a fire. She also informed them that she had disbanded the League of Assassins and released it's members from their vows. Malcolm then became engulfed in anger towards Oliver and promised retribution. Later Malcolm requested a meeting with Damien and offered a deal in exchange for information on who Oliver loves most. Damien however was uninterested as he believed it was Felicity and they'd already taken care of her but Malcolm told him it wasn't Felicity that Oliver cares for most. Damien's attention now piqued Malcolm revealed that the person Oliver loves most is his son William.

Having told Damien about Oliver's son, Damien makes Malcolm part of his consultant team and a H.I.V.E. board member. At a meeting to discuss Genesis, and the need for Ruvé Adams' mayoral campaign, and Malcolm upon Damien's request confirmed that Quentin was indeed a mole for Team Arrow. Later as part of Damien's plan to force Oliver out of the campaign race Malcolm abducted William from his house, and brought him to Damien.

Appearing in Thea's home, he adamantly denied his involvement in William's kidnapping and commented that Thea should know him better than to ask that question. Later, after learning that Malcolm was the one responsible for kidnapping William all along, this proves to be the last straw. Enraged, Thea told him that the days of his lies when he drops into her home and his lies about how everything is for them was over. Malcolm ranted and told her that she would have been dead ten times over had he not raised her from a spoiled rich kid into a warrior and that all he has gotten from her was venomous spite. This decision would cost Oliver his mayoral campaign, a relationship with his son, and the breaking of his engagement.

Malcolm visited Damien in prison to inform him that H.I.V.E. wasn’t going to rescue him as they’d grown tired of his tendency to kill fellow members whenever he gets miffed, but they do wish him luck in the trial. Damien in anger attempted to use his magic on Malcolm but to no avail and Malcolm simply laughed and sarcastically reminded him that performances issues are common for his age. However Malcolm had secretly made a deal with Damien to return his destroyed idol to him and break him out of jail in exchange for sparing him and Thea from Genesis. Malcolm later met up with Damien’s "ace in the hole", Andy Diggle. At some point soon after Malcolm somehow had his left hand restored.

To obtain the idol Malcolm had several of his league followers to hijack a missile shipment into the city as a distraction for Oliver and John but had Andy go with them undercover to ensure they remained away from the Arrowcave. While this occurred Dark Archer breached the Arrowcave with several of his followers and stole the idol but was briefly stopped by Thea, but when she had him dead to rights she hesitated and Dark Archer knocked her out and fled with the idol. Malcolm sneaked in to see Damien in prison and presented the idol to him but Damien revealed the idol is missing a piece and surmised that the team must have kept it hidden separately in case it was stolen. Later Dark Archer lured Team Arrow into a trap seemingly to kill Green Arrow but was really a set up for Andy to take a bullet for him, thereby gaining their trust enough to give up the last idol piece’s location. Thanks to a prison break caused by Michael Amar/Murmur Team Arrow was divided among the prison trying to contain it, allowing Dark Archer to slip back in unnoticed. However he ran into Speedy and Black Canary and fought Speedy alone yet again and succeeded again, reminding her that her hesitance to kill will always stop her from beating him. Dark Archer caught up to Damien after his powers had been restored and insisted they go before the police arrive but not before Damien attacked Laurel, Malcolm escaped with Damien, Andy and Michael soon after.

Malcolm was present together with Michael Amar and Brick while Damien resumed control over H.I.V.E. When two members resisted Damien used his powers to kill them both.

In Tevat Noah Malcolm spoke with Thea who had been kidnapped and brought into the safehaven. He mentioned that the idea of Genesis from Darhk was not much different from the undertaking he had tried himself. He believed the world to be dying and Genesis would be their best option. Thea told him he was insane and demanded to be brought to Alex. Malcolm brought her to Alex where he learned Lonnie Machin had entered Tevat Noah and was killing men of Damien while threatening to destroy the air supply which would kill anyone. Alex asked who Lonnie Machin was and Malcolm jokes he was like a former boyfriend of Thea.

Malcolm and Thea went to the building which controlled the air supply. Thea demanded a weapon but Malcolm denied it and told her to go to hand to hand if needed. As Thea tried to talk Machin down Malcolm noticed multiple explosives in the building. He shot Machin in the shoulder and stopped him from blowing the place up. Machin managed to escape.

Malcolm later found Thea over Alex who had been killed by Machin. Malcolm asked where Machin was but he had vanished. Malcolm ordered his soldiers to take her away. Malcolm demanded her to comply with her but as Thea remained stubborn he forced her to swallow a pill that would make her obey him.

He then talked to Ruve Adams who scolded him for not having dealt with Lonnie Machin. She learned Oliver Queen and John Diggle had entered Tevat Noah and ordered Malcolm to take care of it. Using his drugged daughter as bait Malcolm managed to capture Oliver. Malcolm taunted Oliver that he had the inability to do what is needed. As Diggle bursted in and took out his soldiers Malcolm and Thea were forced to flee. He talked to Ruve Adams who had ordered all the citizens to kill Oliver and Diggle on sight. As Malcolm questioned this Adams told him if he could not take care of this he might have no purpose in H.I.V.E.

Malcolm, Thea and a group of soldiers managed to find Oliver and Diggle and attacked them. Malcolm fought Diggle but was forced to give up as Thea overcame the drugs and she and Oliver cornered Malcolm. The group then saw Machin on a screen who demanded Damien to show up or he would kill his wife and daughter. Malcolm informed them about Machin and as Thea criticized him he told her they could discuss his parenting philosophy later. Oliver told him they would go after Machin and Malcolm would lead the evacuation if they would be unable to save Tevat Noah.

As the place got blown up Malcolm evacuated the people. He then informed Damien that his wife had been killed by Machin. He told him that their plan had failed and that even if he managed to destroy the world there would be no Ark to stay safe. Damien told him that if there is no place to be safe he would let it all burn.

Saving Star City
Obviously dissatisfied with Damien Darhk's decision to destroy the world completely, Malcolm went to the Arrowcave, just in time to stop the Ghosts' attack on Team Arrow. His timely intervention saved Thea Queen and helped other members of the team. Malcolm then joined forces with Thea, Curtis Holt and Felicity Smoak to locate Cooper Seldon, whom Darhk left in charge of operating the nuclear attack.

Post-Genesis
Malcolm appears in the Dominators alternate reality, as an hallucination. When Oliver and his allies try to escape, Malcolm shoots him with an arrow and is engaged in combat with his daughter. During the confrontation it is revealed Malcolm is alive, at least as far as Thea is aware. Thea gains the upper hand and kills the hallucination.

Joining the Legion of Doom
A few hours after Damien Darhk's defeat, Malcolm watched the news, where he discovered that Damien Darhk was killed by the Green Arrow. Suddenly, he was approached by Eobard Thawne/Reverse-Flash, a time travelling speedster from the 26th century, and a younger version of Damien Darhk from 1987. At first, Malcolm was confused, as he just watched Damien getting killed. Eobard explained the situation and offered Malcolm a chance to rewrite his own history including preventing Tommy's death, in exchange for aiding him in stealing various relics he seeks. Agreeing Malcolm joined the Legion of Doom. He was also informed of their enemies, the time traveling vigilantes known as the Legends, who Sara, now known as "White Canary", was a part of.

To draw the Legends out the trio traveled to 1927 and made a deal with Al Capone. In exchange for aiding them lure out the Legends they would ensure Capone wouldn't be caught by the authorities as he is destined to. They also informed him of Elliot Ness' future role in convicting him. When the Legends were successfully drawn out Eobard abducted Sara and Professor Stein. Malcolm offered Sara a deal in exchange for the amulet, he'd ensure the Queen's Gambit sinking never occurs, revealing his responsibility in it's sinking and the indirect role he played in Sara becoming The Canary. However Sara declined his offer.

When Eobard infiltrated the Waveirder disguised as Stein he returned it to 1927 and Malcolm led several of Capone's men inside to kill the Legends, while he obtained the amulet. While searching the bridge for it he encountered Sara and they fought and Malcolm gained the upper hand, and mocked Sara for rejecting his offer. However Sara simply told him she already had a better life and got the drop on him. Before she could kill him Malcolm offered Stein's location but only in exchange for sparing him and giving him the relics. Reluctant, Sara agreed.

After obtaining both relics Eobard combined them displaying a map. Malcolm sarcastically called it a "portable planetarium" before Eobard exasperatedly corrected him that it's a compass, one which could lead them to the Spear of Destiny. However to located it Eobard informed Malcolm and Damien they'd need one more thing, Captain Rip Hunter.

Malcolm Merlyn and Damien Darhk traveled to 1967 Los Angeles. As the two walked the city Merlyn mentioned how he wanted to see Frank Sinatra, before complaining about how vague the medallion was. The two decided to find some transportation as they became tired of walking. Two bikers threatened to rob them but Malcolm calmly told them they would not kill them if they would give them the bikes. As the bikers refused Malcolm and Darhk beat them to death using League techniques and took their bikes.

Merlyn and Darhk found Rip Hunter, who was now in the persona of a film student. As they confronted him he did not seemed to understand who they were. The Legends showed up and Merlyn and Darhk engaged them in combat. When the cops showed up Merlyn and Darhk fled the scene. The two later went to the police station to retrieve Rip and killed a number of cops on their way in, but found that Rip had already been taken away by the Legends. Darhk and Merlyn gave chase but the Legends escaped with the Waverider.

Merlyn and Darhk found Vixen, Palmer and Heywood as they talked to George Lucas, who had dropped out of film school, which had resulted in Palmer and Heywood losing their knowledge. Merlyn and Darhk swiftly defeated and captured all of them. They learned that Lucas had the spear but had dumped it at the city dump. They forced the group to search for the spear in the trash compactor.

Malcolm and Damien lost patience and Malcolm suggested that they kill one to motivate the others. However, before they could do so, the Waverider appeared and blasted them away. Sara and Jax attacked Darhk and Merlyn and engaged them in combat. Merlyn and Darhk quickly gained the upper hand, but the other Legends got their abilities back and joined the fight. Reverse-Flash showed up and picked Merlyn and Darhk up, before the three threatened the Legends. Rip showed up, bluffing that he had recovered his memories, but when he was exposed as a fraud, the Waverider again fired upon the three villains. However Reverse-Flash captured Rip before he could escape and took him away. Later Merlyn and Darhk prepared to torture Rip for information about the spear.

Personality
Before his wife's death, Malcolm was a caring man who loved his wife and son very dearly, and was a devoted businessman and humanitarian, striving to save Starling City just like his wife, Rebecca. After his wife's death he became heartbroken and was haunted with guilt that he had not been able to help her. Malcolm's love for his wife was so great when he confronted the man he thought killed Rebecca, he told him he had taken everything from him. During his mourning period he also had an affair with Moira, which guilt riddled him even more. He was shocked and confronted the (presumed) killer which ended with Malcolm killing him. Unable to live with what he had done he left his son and went to Nanda Parbat. Training there he changed his perspective on the world and how he could help his city. He returned as an apathetic, calculating, and ruthless man. He began to develop a plan to destroy the Glades completely, believing that this way he could help the city. He believed what he was doing was right and is for the greater good, and was willing to do anything, regardless of the number of lives he ruins and will kill anyone who gets in his way to see his goals fulfilled, which makes him somewhat of a sociopath. He truly believed in the righteousness of his cause, projecting this in his acceptance speech for "humanitarian of the year". He also truly loved his wife, still wearing his wedding ring so many years after her death.

Malcolm is a charismatic person, able to project his own beliefs and self-righteousness into his words. He seemed to have something of an ego as Robert Queen said that Malcolm had "something of a God-complex" and had a hostage read out that he will kill them if the Arrow "doesn't surrender to his authority". He blames all the people living in the Glades for his wife's death, not just the person who killed his wife, but also the ones who walked past his wife while she was dying which unfortunately results in his own son's death. Like Oliver, he is prone to emotional outbursts, although this rarely happens due to him being calm and level-headed. Malcolm also has no guilt or remorse for using people for his personal gain and then killing them once they became loose ends to keep them from going public with information he wouldn't otherwise want to be public information. Likewise when he had drugged Thea with Vitura, he had her kill Sara Lance to force a reaction from of the League of Assassins. Knowing Oliver would try to protect his half-sister, he used this to create a duel between Oliver and Ra's. He truly believing Oliver's desire to save Thea would have been enough to kill Ra's which would make the League stop hunting him. In the process he had lied to and manipulated everybody including his own daughter. Malcolm is also tactically intelligent, as once the Undertaking was nearing, but the Arrow was endangering his mission, he began his own "anti-Arrow" persona as the Dark Archer knowing that the SCIS would blame the Arrow and people would lose faith in him as well as releasing Slade Wilson from his cell on Lian Yu to have Oliver re-awaken his killer side. He was shown to be quite if not absolutely confident in his fighting skills as he beat the Hood multiple times in combat. He mentioned the reason he came out on top was because he knew what he was fighting for. Malcolm is calm in battle and willing to fight anyone that is a threat to himself or the ones he cares for. So far, the only two people he is afraid of are Ra's Al Ghul and Vandal Savage.

Despite his insanity, selfishness, ruthlessness, and cold heart he still loves Tommy dearly and wants what's best for him. He has, however, a rather harsh way of showing it which often forces Tommy away. For example, Malcolm cut off Tommy's trust fund and harshly told Tommy he was worthless in order to "jolt him into adulthood". After Tommy is killed during the undertaking, Malcolm is sad and regretful, and he begins searching for ways to be a part of Thea's life. Further, he began to pressure Moira into telling Thea that he is her biological father. When Moira was murdered Malcolm swiftly returned to Starling City to watch over Thea, despite still being hunted by the League of Assassins. Malcolm loves Thea as much as he loved Tommy, and with similar harshness. When Thea requested he teach her how to fight he gave her no special treatment. It should be noted his regime was effective, since he made Thea a capable fighter within 6 months. Malcolm strong parental instincts displayed themselves when he shot the assassin Chase for attempting to kill Thea and when he made Tommy's safety his priority during the attack on his humanitarian ceremony. Some however, question whether Malcolm's ambition does not sometimes overpower his love for his children, since despite his grief over inadvertently causing Tommy's death, Malcolm manipulates Thea into killing the Canary so that the League will mark Thea for death and Oliver will be forced to fight and kill the League's leader Ra's al Ghul. If Oliver could kill Ra's, then Thea and Malcolm would both be saved from the League. This scheme is risky and places Thea in danger, indicating that Malcolm might not have learned everything he could from Tommy's death. Or it might show that, despite having inadvertently killed his son, Malcolm remains daring enough to take the drastic, manipulative steps he thinks are required to beat an international organization of assassins.

Despite his ruthlessness it should be noted that Malcolm's parental instincts extend in a limited way to Oliver Queen, Tommy's best friend. After beating the Hood Malcolm unmasks him and exhibits regret upon learning his enemy is Oliver. He also seemed devastated for Oliver´s apparent death at the hands of Ra´s. Still, Malcolm's love remains centered on his two children, and his apparent affection for Oliver does not prevent him from manipulating Oliver into fighting Ra's al Ghul, even though he was absolutely confident Oliver had what it took to beat Ra's. Malcolm´s paternal instincts for Oliver have however, been destroyed after the latter´s betrayal cost him his leadership of the League and, soon after, led to its disbandment. Despite this fallout with Oliver and resulting alliance with H.I.V.E, he refrained from revealing important information about Team Arrow to Darhk, like their identities and the location of their lair. He also made a sarcastic and humorist comment to Oliver after his speech, showing that his hatred for him might be lessening although this feeling is hardly mutual.

Some time after this, however, Malcolm learned that the man he killed to avenge his wife was not his wife's killer. In truth, Brickwell murdered her. Malcolm expresses to Oliver his belief that all his decisions and the deaths he caused could have been avoided if he had not killed the wrong man. He seemed set on redeeming himself, since he spared Brickwell and was willing to train Oliver.

After this he started to work together with Team Arrow. While he maintained a sarcastic and cold persona, he seemed to respect and even care for them. During a battle with the League he saved both Laurel and Felicity's lives. He later saved the entire team and Oliver from the Omega Virus and worked with them to keep the virus from destroying Starling City. It was revealed, however, that Malcolm still had an angle since he had agreed with Oliver that when Ra's was dead, Malcolm would be his successor. Malcolm also participated in the rescue mission to retrieve Oliver, Felicity, John Diggle and Thea from Damien Darhk's headquarters and even saved Oliver from being beaten to death by Damien by shooting him with arrows. Despite his fallout with the Team after the League Civil War, he lingered after Damien stabbed Laurel with an arrow, indicating shock or even regret over his role in her death, a few moments later.

Malcolm is shown to have a deep interest in various warrior cultures. His office was decorated with Asian statues and Japanese swords. In a secret room adjoining his office he kept racks of swords and other weaponry from multiple cultures. He supported the Buddhist monk Ken Zhi Jansen and spend time meditating in his temple.

Since he became the new Ra's al Ghul, Malcolm has displayed an authority demeanor, when Laurel request that he use the Lazarus Pit to bring back her sister Sara, he refused, telling her that in thousands of years they never had resurrected a dead person with the pit and that it might have horrible consequences. When she kept insisting he told her he does not have obligations to anyone, and she does not get to ask a request like that. Laurel and Thea did manage to convince him at the end, but this might partially have been because he wanted to prove his love for his daughter, since it was he who had made her kill Sara.

Malcolm became quite convicted of the importance of the League of Assassins. He refused to give up the position as their leader even if it would cost the life of his daughter. He mentioned the League was larger than him or Thea, as the League was a invisible force that can influence the entire world for the better and therefore he refused to hand this responsibility to Nyssa al Ghul.

Malcolm can be quite vengeful, after he lost his left hand and was removed as the leader of the League of Assassins, by Oliver, he revealed the existence of the latter's son William, to Damien, to get revenge on Oliver. This also caused a severe strain in his relationship with his daughter, William's aunt. Despite this, his love for her remains unscathed, since his alliance with Damien Darhk is based on the latter sparing him and his daughter from H.I.V.E.'s endgame, Genesis. However after realising that Darhk would move forward with Genesis after the destruction of Tevat Noah, he joined forces with Team Arrow to save the world from nuclear annihilation. Despite this change of heart, his relationship with his members seemed strained, especially with his daughter, likely due to the his role in Laurel´s attack and him brainwashing Thea a second time in Tevat Noah

Despite his love for Thea, Malcolm has no tolerance for being disrespected by his daughter, as he coldly reminded her of how she was a weak spoiled brat, and he turned her into a strong warrior, as well as pointing out her shortsightedness. Despite being a parent himself, Malcolm is not above kidnapping innocent children, like he did with William (off-screen), in order to help Damien get leverage over Oliver, that would force the latter to stop running for mayor of Star City.

Abilities

 * Expert escape artist: Malcolm is a trained escape artist due to his time in the League of Assassins, according to Malcolm his skills are so great that he claims that no prison can hold him not even Oliver's secret prison on Lian Yu. However, Malcolm was unable to escape from Nanda Parbat when he was captured by Ra's al Ghul presumably due to his injuries.
 * Expert interrogator: Malcolm is a trained torturer due to his time in the League of Assassins, however, Malcolm oddly prefers diplomatic solutions before resorting to torture as seen when he offers Sara Lance the chance to rewrite her history. Malcolm is also a trained hypnotist and proceeded to use hypnotic-regression therapy in a failed attempt to restore Rip Hunter's memories.
 * Expert knife wielder: Malcolm is proficient in the use of knives as he was able to successfully injure John Diggle with a knife throw while retreating. Malcolm is also capable of wielding a knife during single combat as seen when he fought Sara Lance.

 * League of Assassins training: Malcolm has gone through the training that all members of League of Assassins do. Malcolm was considered to be one of the finest members of the League, enough that he became Ra's al Ghul's Horseman, his right hand man.
 * Master archer: Malcolm is a highly skilled archer due to his time in the League with archery being his weapon of choice. Oliver Queen himself comments Malcolm's skills after noting on how tight the grouping of his arrows were when Malcolm killed Adam Hunt.

 * Master of deception: Even before his time in the League, Malcolm was talented in the art of deception able to fool and convince others of his agenda even experts of seeing through deception such as Oliver and Ra's. However, Malcolm actions and his nature as a liar make it difficult for people to ever believe him as shown when he tried to convince Team Arrow of Oliver's undercover operation and the threat of the Alpha-Omega virus. Due his archery and combat skills, Malcolm was able to successfully portray himself to Damien Darhk as the "Green Arrow" when Oliver was unable to.
 * Master strategist, tactician, and businessman: For several years Malcolm was the CEO of Merlyn Global Group, overseeing its daily activities and ensuring its success as a multibillion-dollar corporation. Malcolm is an exceptional strategist and tactician with the successful execution of the Undertaking after 6 years of planning and development. Malcolm was also successful is faking his death, able to stay hidden from both the League and Oliver for over a year. Malcolm was also a key strategic advisor for Oliver during his conflict with Ra's al Ghul, coming up with the plan to dispose of the latter and install himself as the next Ra's al Ghul.
 * Master swordsman: Despite his preference for archery, Malcolm is a trained and highly skilled swordsman often practicing fencing in his spare time to maintain his skills.

 * Multilingual: Malcolm is capable of speaking English, Mandarin, Spanish, and Arabic.
 * Network: Malcolm has a dense network of information of throughout Starling City, including the coroner's office which is how Oliver believes he faked his death. Since becoming Ra's al Ghul, Malcolm now has access to all the resources of the League of Assassins before Nyssa al Ghul dissolved the League, however, Malcolm does still control a small collection of loyalists to the League. Malcolm is still able to infiltrate a prison to converse with Damien while he was imprisoned, with the later remarking his resourcefulness.
 * Occult Knowledge: Malcolm is aware of the existence of magic and mysticism, knowing the existence of the Lazarus Pit. Since becoming Ra's al Ghul, Malcolm has gained a higher understanding of the Lazarus Pit and its functions, Vandal Savage, and Damien Darhk's magic. However, Malcolm was unable to figure out why Damien's magic backfired against Thea.
 * Peak of human physical condition: Malcolm is in top physical condition for a man of his age due his training with the League of Assassins. Malcolm has demonstrated enough strength to break Oliver's bow with a single strike, dent a steel beam with a single kick, and topple the highly durable Danny Brickwell with only a few strikes. Malcolm's reflexes are fast enough to catch or deflect an incoming arrow shot at him by Oliver. Since Oliver cut off his left hand, Malcolm's physical skills has been able to continue his activities thanks to his new cybernetic prosthetic hand.
 * Stealth: As a highly trained assassin Malcolm is a master in the art of stealth, as his ability to break into buildings and disappear without a trace is the reason why he is called "The Magician" by the League of Assassins. Malcolm skills have repeatedly made of mockery of the Arrowcave's security, despite its relocation and upgrades. Malcolm has even managed to infiltrate Nanda Parbat undetected, which Malcolm claims to be difficult.
 * Toxicology: Malcolm was able to use votura to create a drug that made Thea kill Sara without remembering it.

Equipment

 * Customized PSE X-Force Super Short Short Draw LF Compound Bow: While the rest of the League primarily uses modified PSE Chaos AD compound bows, as the Dark Archer Malcolm uses a similar bow as his signature weapon of choice: A customized compound bow.
 * Quiver: A black arrow container strapped to Malcolm's back. He uses it to carry his arrows as his villain alter-ego, the Dark Archer.
 * Dark Archer suit: Malcolm wears a protective suit, as his villain alter-ego of the Dark Archer, to hide his identity from his victims. It is similar to the suits used by members of the League of Assassins, aside from some minor differences. It is unknown what materials it's made out of, with the exception of kevlar.
 * Customized hunting arrows: Malcolm creates and designs his arrows himself. The arrows he used have arrow heads with three "Teflon-coated titanium blades" on each arrow, with the blades serrated for splitting bones, and the shaft itself is made of "specialized polymer stronger than typical carbon fiber". As such, it is safe to assume that the arrows he uses are deadlier than those used by The Arrow.
 * Trick arrows: Shortly after his return, Malcolm uses an explosive arrow to save Thea and seemingly kill one of Slade's Mirakuru henchmen.
 * Throwing knives: When fighting Oliver and John, Malcolm utilized double bladed throwing knives.
 * Swords: Malcolm uses a huge variaty of swords from different cultures. He first used a league of assassins scimitar to kill two police officers, during his third fight with Oliver. Malcolm was shown using the league of assassins scimitar against Oliver, though he was very quickly disarmed by Oliver. While training Thea they used both Japanese and Chinese swords. When preparing to kill Brickwell he carried another style of scimitar, similar to the one used by Nyssa al Ghul.
 * Voice filter: Malcolm uses this device to change his voice regardless of who he spoke to as the Dark Archer. This could be for the purposes of intimidation as it changed his voice to a deep, low growl.
 * Smoke bombs: After incapicating Nyssa, he threw a smoke bomb to quickly escape the scene.
 * Cybernetic hand: Malcolm acquired a cybernetic hand of unknown materials and origin while planning Damien Darhk's prison break. He used it for the first time when stealing the idol from Team Arrow and has been wearing it ever since. This allows him to use a bow and complete various other tasks that would be impossible to complete one-handed individuals. This prosthetic is specifically built for his left hand, which was cut off by Oliver during their duel at the end of the League civil war. The prosthesis is seemingly capable of all known functions found in an organic hand, and has not been known to hamper Malcolm's dexterity. Given that it is made from top of the line technology, it presumably has the same degree of tactile sensitivity as a human hand, as such technology has been known to exist in contemporary science as of 2389.

Former equipment

 * Demon's Head ring: Malcolm weared a particular ring which symbolized his position as the Demon's Head. Malcolm no longer wears it, as it was destroyed by the last Ra´s Al Ghul, that promptly disbanded the League of Assassins.
