"My link to the Collective has been severed for nearly four years. If I die, everything that I have accomplished in that time, everything I achieved as an individual, will be lost. My memories, my experiences. It will be as if they, as if I never existed."
"I think you're a little more memorable than you're giving yourself credit for. You don't need the Collective to validate your existence. You've made an impact on every member of this crew. That's your legacy."
— Seven of Nine and B'Elanna Torres, 2377

Seven of Nine, Tertiary Adjunct of Unimatrix 01 (or Seven for short) is a 24th century Human woman, and former Borg drone, born as Annika Hansen in the year 2348.

She was assimilated, along with her parents, in 2356, but was later liberated by the crew of the USS Voyager in 2374. In the following years she began to reclaim her humanity, but still preferred to go by her Borg designation rather than her given name. She eventually returned to Earth aboard Voyager in 2377.

Seven served on the USS Intrepid-A as the astrometrics officer from 2378 to 2380, she rejoined the Intrepid-A in 2399, Seven later joined the MACO squad aboard the Intrepid as a Corporal, wanting to be part of the Intrepid crew again.

Rejected by Starfleet for her Borg past, Seven then joined the Fenris Rangers, helping instill justice in lawless and dangerous regions of the galaxy. Instrumental in the forging of a truce with a new Borg faction, she was given a field commission by Admiral Picard and eventually joined Starfleet by 2401. Following the destruction of the Borg, Seven was promoted to the rank of captain and given command of the USS Enterprise-G.

In an alternate timeline created by Q, Seven was married to her former Voyager crewmate Typhuss James Halliwell in the year 2399. Their daughter Annika Hansen II was born later that same year.


Annika Hansen


Annika Hansen in 2354

Annika Hansen was born on the Tendara colony on stardate 25479, to human exobiologists Erin and Magnus Hansen. Because her parents moved frequently because of their work, Annika spent a great deal of time with her aunts, Irene Hansen and Helen, on Earth.

One of her ancestors was Sven "Buttercup" Hansen, a 22nd century prize fighter.

Her maternal grandmother, Elaine Bergstrom, was a security officer aboard the USS Enterprise during the 2270s. She died in 2349.

By the time that she was five, Annika was living with her parents on Heronius II. She often spoke to her Norwegian maternal grandfather via subspace. Shortly before her sixth birthday, she was visited by an older version of herself (though Annika did not realize her identity) who tried to dissuade her parents from their plans to leave Federation space. Following this encounter, Annika began to have disturbing dreams of black cube-shaped starships.

In 2354, Annika and her parents left Heronius II aboard the USS Raven, as they finally had approval by the Federation Council to begin a study of the mysterious Borg Collective. After spending many months searching for a Borg ship, the Raven had broken regulations and had crossed the Romulan Neutral Zone. However, just as they were contemplating a return to Earth, they encountered a Borg Cube. After six months of observation, the Raven followed the cube into a transwarp conduit and into the Delta Quadrant.

Life as a drone

The Hansens gathered a large amount of data about the Borg over the next two years, however it came to an abrupt end in 2356, when the Raven was detected by the Borg and attacked. The Borg pursued the Raven to a planet just inside B'omar space, where the science vessel crash landed. While her parents were quickly assimilated, Annika attempted to hide, but was later found and also assimilated. After five years inside a Borg maturation chamber, the fully grown Annika Hansen was given the designation Seven of Nine and served aboard a cube. In 2368, Seven was briefly disconnected from the hive mind when she and several other drones in her unimatrix crash landed on Planet 1865-Alpha. Scared of being alone, she injected her fellow drones with nanoprobes and established another collective, before being rescued and re-assimilated.


Seven of Nine in 2374

In 2374, Seven was selected as a liaison to work with Captain Kathryn Janeway and Lieutenant Commander Tuvok as part of the alliance against Species 8472. Their mission was to develop a modified nanoprobe weapon that could destroy 8472 bio-ships and force them to withdraw back to fluidic space. After the mission was successful, Seven attempted to assimilate the Voyager crew, but her link to the collective was severed.


7of9 Brig

Seven, initially resistant to life on Voyager

After many of her implants were successfully removed by Voyager's EMH, her mental and emotional recovery as well as social training was going to be a huge task. After several attempts to communicate with the collective, Seven eventually accepted that her place was aboard Voyager as an individual. Earning the trust and respect of Captain Janeway, Seven began to work on several projects to enhance Voyager's capabilities, such as working on transwarp drive and the construction of the astrometrics lab.

On stardate 53689, Seven analyzed debris that was destroyed with Borg technology. She confirmed that it was Borg technology. During that time, Seven told Janeway that she was receiving a Borg message but was not sure what it meant. When Voyager was trapped by a Borg ship of some kind but found it's tactics odd. After they failed to modulate their shields against the Borg ship, Seven suggested that she attempt to board the ship knowing that she might still be taken as Borg. Captain Janeway agreed but advised in sending Chakotay, Tuvok and an away team disguised as Borg to the ship.

In mid 2374, shortly after discovering the Hirogen communication relay stations, Voyager was intercepted by the individual Borg, Hugh. Hugh had learned about Seven severance from the collective and wanted her to be his Second of the Independent Nation of Borg. After some deliberation, Seven decided to remain aboard Voyager.

Seven of Nine

Seven of Nine in 2375

In 2375, Seven suffered a telepathic assault by a race known as the Skedans. As a result, the personality of Annika Hansen briefly resurfaced, as part of a plan by the Skedans to exact revenge on the Borg after the near-completed annihilation of their race.

Later that year, Seven became the target of an assassin aboard Voyager after a series of potentially fatal accidents occurred. An in-depth investigation revealed that Voyager herself were responsible for the accidents, after a specially programmed bio-neural gel pack had been installed by Ensign Roberta Luke. Luke was revealed to be a Section 31 agent who had been assigned to Voyager in 2371 as part of an operation to destroy the Maquis. After re-establishing contact with the Federation in 2374, Luke was ordered to kill Seven, but she herself was killed by the Srivani shortly after. In 2377, Seven and Lieutenant Tom Paris were abducted by the Chiar while Voyager was undergoing repairs in orbit. The Chiar were dependent on nanotechnology. After infecting Paris with memory suppressing nanites, Seven was tortured by the Chiar, and eventually removed and replicated Borg nanoprobes. Unfortunately, the nanoprobes began assimilating the Chiar, but Seven was able to modify Paris' memory nanites to disable the Borg nanoprobes.

In the Alpha Quadrant

Following Voyager's return to the Alpha Quadrant in late 2377, Seven lived with her aunt, Irene Hansen and joined a Federation Think Tank. (VOY novel: Homecoming)

In 2378, Seven served on the USS Intrepid-A as astrometrics officer until 2380, when Seven took a job as an instructor at Starfleet Academy. (Star Trek: Intrepid)

As of 2380, Seven of Nine was an instructor at Starfleet Academy. During the Borg incident of that year, Seven was in contact with the Borg super-cube that assimilated Kathryn Janeway through her implants. After bringing her concerns to Starfleet and being overruled, Seven went rogue and booked passage with Antin Vargo so that she could reach the derelict Borg Cube. When passage to the Cube proved impossible, she instead joined the USS Enterprise-E and its crew so that she could bring her concerns to Captain Jean-Luc Picard. As they proceeded to investigate, the Borg launched an invasion of Earth and demanded that Seven be turned over to them in exchange for the Borg to discontinue their attack. Instead of being returned to the Borg, however, Seven and an Enterprise away team boarded the Planet Killer, encountered by the USS Enterprise, over a century prior. Seven bonded with the device and attacked the Borg Cube that was attacking Earth, releasing the virus program devised by Geordi La Forge-while in the process. When the Planet Killer was destroyed, she was rescued by Vargo. (TNG novel: Before Dishonor)

Near the end of the year, she was appointed Deputy Federation Security Advisor by Federation President Nanietta Bacco, out of recognition of her unique skills in assessing the Borg threat during their attempted extermination of the Federation and its allies. (ST - Destiny novel: Gods of Night)

She frequently clashed with senior members of President Nanietta Bacco's Cabinet, including her immediate supervisor, Federation Security Advisor Jas Abrik, and Federation Starfleet Commander-in-Chief Edward Jellico. Despite this, she was involved in several Think Tank and Starfleet Command meetings to determine possible strategy against the invading Collective. Feeling that transphasic torpedoes, Starfleet's only effective weapon against Borg vessels, would eventually be adapted to, Seven advocated the creation of a thalaron weapon, a suggestion that was met with strong opposition as too genocidal, even if the Borg had no such reservations. When Captain Picard requested an allied fleet of reinforcements, Seven declared it insufficient and suggested that the quadrant evacuate through one of the subspace tunnels at the Azure Nebula, again being rebuked. Seven presented a grim outlook to President Bacco when over seven thousand Borg cubes emerged from the nebula and destroyed the meager fleet that had been assembled. (ST- Destiny novel: Mere Mortals)

Seven was present during many of the regular reports to President Bacco from her staff and the Starfleet liaison, Leonard James Akaar. Seven suspected that the Borg were assimilating advanced propulsion technology as they invaded, causing them to move quicker than expected. Seven was also pessimistic about evacuating core worlds nearing danger, as the Borg would likely still hunt down and destroy escape vessels. As the Borg fleet entered the Sol system, advancing past Jupiter, Seven was present in the Monet Room in the Palais de la Concorde, along with the remainder of the presidency. President Bacco suddenly wondered why former President Min Zife had left the painting Bridge over a Pool of Water Lilies. Seven thought that he had found it a point of focus while attempting to concentrate; but Akaar knew that Zife had left it as a reminder of what they fought for - air, beauty, history and everything that was thought of as the legacy of Earth. When the Borg Collective was disbanded by some unusual actions from the Caeliar, Seven's Borg implants dissolved into a fine silvery powder, and she broke down into tears from the loss of the ever-present voices in her head. As she recovered, she stated that her name was Annika. (ST - Destiny novel: Lost Souls)

In 2381, during the Caeliar dissolution of the Borg Collective, Seven's remaining Borg implants were removed, following this her humanity had apparently fully reasserted itself, as she then insisted on being called Annika. Seven later redacted this claim after she discovered her Borg technology had been transmuted into Caeliar catoms and she suffered a mental breakdown as a result of her transformation.

Seven took the death of Admiral Janeway particularly hard, and while teaching at the Academy, cared for her Aunt Irene, who was becoming more and more unstable due to Irumodic Syndrome, a degenerative mental condition with no known cure. When Voyager was assigned to Project Full Circle, Seven became even more distraught knowing that her entire family would be departing and she would be alone with her aunt. After her aunt passed away, she would be truly alone. When Chakotay paid her a visit (after he was not assigned to Voyager any longer), he found Seven in a poor state, her home in disarray and herself unkempt, under great stress. With the deaths of their closest friends Kathryn and B'Elanna, the two mourned and comforted each other after Voyager departed for the Delta Quadrant. (VOY novel: Full Circle)

Return to the Delta Quadrant

Seven of Nine CotS German cover

Seven of Nine in the 2380s

In 2381, Seven suffered a mental breakdown due to the voice in her head which repeatedly informed her that she was Annika Hansen. However, Chakotay and Icheb were able to help her using meditation techniques. It was also realized that although the Caeliar had seemingly removed her Borg implants, they had in fact replaced them with their own Catoms. Seven then realized she needed to meet the Caeliar to find out why she hadn't been invited to join the gestalt. As a result, Chakotay and Seven followed and eventually joined the Voyager fleet, headed for the Delta Quadrant. Once there, Voyager encountered the Indign cooperative, several species living together in a symbiotic relationship, who worshiped the Borg.

A disembodied Neyser consciousness was able to communicate with Seven via her Catoms. After another telepathic encounter with the Indign cooperative, Seven was able to overcome the voice in her head and embrace that aspect of her personality, in the process discovering that she had voluntarily refused to join the Caeliar Gestalt and the voice was a parting gift from the Caeliar to remind her to embrace her identity. Following this, Seven claimed that she was part Borg, part Human and part Caeliar. (VOY novel: Unworthy)

During the investigation of the Children of the Storm, Seven played a critical role in theorizing and discovering the "mother" of the Children. Meanwhile, she eventually came to realize that her frustration with Counselor Hugh Cambridge originated in deeper feelings, and she expressed her desire to pursue a romantic relationship with him after the mission ended. (VOY novel: Children of the Storm)

In 2385, Seven left Starfleet after it decided the fact the Borg were no longer a threat after a decade of non-threatening actions from them. Seven saw their decision as dangerously reckless. Seven then accepted a job as a researcher for the Daystrom Institute. (STO website: The Path to 2409)

Life in the Alpha Quadrant

"He was a son to me, Jay. This is for him."
Seven of Nine to Bjayzl, 2399
Seven of Nine with Icheb, 2386

Seven with Icheb in 2386


Seven's Ranger ship

Sometime after Voyager returned from the Delta Quadrant, Seven applied to join Starfleet only to have her application rejected. This was despite strong opposition from Admiral Janeway, who went so far as to threaten to resign her commission. (PIC episode: "Hide and Seek")

By 2386, Seven joined the Fenris Rangers, a peacekeeping force that operated along the Romulan Neutral Zone, where she worked closely with a woman named Bjayzl. During that time, she became friends with Bjayzl and told her about her surrogate "son" Icheb. Unbeknownst to Seven, however, Bjayzl was a black market dealer in Borg parts taken from former drones, also known as "xBs", and had infiltrated the Rangers to get close to Seven. It was through Seven that Bjayzl learned about Icheb, by this time a Starfleet lieutenant assigned as a science officer aboard the USS Coleman. In 2386, Bjayzl lured Icheb into an ambush while he was on a reconnaissance mission for the Rangers near Daimanta. She arranged for him to be taken to the Seven Domes facility on Vergessen, where his implants were brutally removed from him without any anesthetic, or even the small mercy of death. In anguish, Seven, who considered Icheb as a son since their time on Voyager, arrived to rescue him; but she was too late. In unbearable pain, he entreated Seven to end his life. Cradling him in her arms, she tearfully bid him farewell before she complied by fatally shooting him with her phaser. Seven spent the next 13 years tracking Bjayzl down. (PIC episode: "Stardust City Rag")

Aiding Typhuss

Seven of Nine (2399)

Seven of Nine in 2399

In the year 2399, Typhuss visits Seven at the 602 Club in Mill Valley on Earth to recruit her to help him find his friends from the USS Voyager, Portia and his daughter Sarah. Its been awhile since Typhuss last saw Seven. Seven tells Typhuss it has been 7 years, 2392, since she last saw him. Seven accepted the mission because it involved their former crewmates from Voyager. Seven later joined the MACO squad aboard the Intrepid as a Corporal, wanting to be part of the Intrepid crew again. (Star Trek: Intrepid episodes: "Seven of Nine and The Admiral", "Seven's New Beginnings")

Aiding La Sirena

Thirteen years later, Seven assisted the La Sirena in battle against a Romulan Bird-of-Prey in orbit of the planet Vashti. Her ship was destroyed, but she was beamed over to the La Sirena and was surprised to see Admiral Jean-Luc Picard on board. She quipped that he owed her a ship before she collapsed. (PIC episode: "Absolute Candor")

Seven kills Bjayzl

Seven vaporizing Bjayzl

Picard explained that he was on his way to Freecloud to find Dr. Bruce Maddox. Upon learning that he had been captured by Bjayzl, who intended to turn him over to the Tal Shiar, Seven helped plan his rescue by offering herself to Bjayzl in exchange for Maddox. Posing as traders, Picard and La Sirena captain Cristóbal Rios "delivered" Seven to Bjayzl, only for Seven (wearing compromised binders) to "break free", revealing her true intentions: to kill Bjayzl in revenge for Icheb's death. Picard was seemingly able to talk her out of murdering Bjayzl and returning with him and his crew to the La Sirena. After Maddox was rescued, Seven declined Picard's offer of a ride, saying the Rangers were sending a corsair to Freecloud to pick her up, but did take two type 3 phasers from the La Sirena's armory. Before beaming back to Freecloud, Seven asked Picard about whether he had rediscovered his humanity after he was rescued from the Borg, and admitted she was still working to find hers "every damn day" of her life. Picard understood this, as he was wrestling with the same. The two amicably parted ways.

However, far from the impression she had given Picard, Seven still intended to kill Bjayzl. She transported into Bjayzl’s nightclub and confronted the criminal businesswoman after clearing out the lounge by shooting her bodyguards, causing all others present to flee, leaving Bjayzl alone. Bjayzl tried to stall until her security arrived, but Seven knew what she was trying to do, and sardonically told her so. Bjayzl then began trying to talk Seven out of killing her, but Seven coldly cut her off with raised rifles and a bitter retort that Icheb had been a son to her. She then vaporized Bjayzl with shots from both rifles. Seconds later, Bjayzl’s security team arrived, and Seven furiously carved a path through them with the rifles. (PIC episode: "Stardust City Rag")

Seven of Nine becoming a Borg queen

Seven acting as "Queen" aboard the Artifact

After Freecloud, Seven was summoned by a communications chip she had given to fellow xB Hugh, the director of the Borg Reclamation Project aboard the "Artifact" in Romulan space. After Hugh was killed by the Romulans, Elnor - who had remained behind while Picard and Soji Asha had used the spatial trajector in the cube's queencell to escape - used the communicator to call Seven to the cube in order to take control of it. Seven accessed the queencell to begin regenerating the damage done to the cube. When the Romulans began venting the stasis-contained drones into space and killing the xBs, Seven decided to link the tranceivers of the disconnected Borg on the cube into a "mini-collective", with herself acting as a sort of Borg Queen, despite her reluctance to essentially assimilate them all over again. The Romulans left the Artifact with their fleet to invade the synthetic homeworld, leaving the cube in the control of Seven and the xBs. When Elnor asked if Seven intended to assimilate him now, the cube's collective said only that "Annika still has work to do" before Seven was disconnected from the queencell. (PIC episodes: "Nepenthe", "Broken Pieces")

While connected to the Queencell, however, Seven witnessed La Sirena being pursued by Narek, prompting her to open a transwarp conduit to follow them to Coppelius. (PIC episodes: "Nepenthe", "Broken Pieces", "Et in Arcadia Ego, Part 1")

The Artifact crashed on the surface, where she reunited with Picard and La Sirena's crew. Here, Elnor decided to stay with Seven as part of her effort to reactivate the Artifact's defenses and aid the xBs. Seven told Picard to "keep saving the galaxy", but Picard replied that it was all on her now. (PIC episode: "Et in Arcadia Ego, Part 1")

Saving history

By 2401, Rios returned to Starfleet after Coppelius, giving La Sirena to Seven to continue her work with the Rangers. After fighting off an attempt by pirates to steal Ranger supplies, she joined with a Starfleet task force, led by Picard and Rios from the USS Stargazer, to investigate an anomaly that proved to be a massive Borg ship. The Borg Queen beamed aboard the Stargazer and took control, and Picard ordered auto-destruct to destroy the Stargazer, seemingly killing everyone aboard, including Seven. (PIC episode: "The Star Gazer")

Seven awoke in an unfamiliar setting, remembering being on the Stargazer, and was shocked to look in the mirror to see her Borg implants missing. She figured out that she and her friends had been sent into an alternate timeline, where her counterpart served as the President of the Confederation of Earth, a xenophobic totalitarian regime. She learned from Picard, whose own counterpart was the Confederation's most feared general, that the entire scenario had been orchestrated by Q. (PIC episode: "Penance")

Reuniting with the others aboard the La Sirena, she travelled with them to the 21st century to correct the timeline, together with a captive Borg Queen that was scheduled for public execution by the Confederation. (PIC episode: "Assimilation")

Paired with Raffaela Musiker, Seven traveled to Los Angeles to seek out the mysterious "Watcher" mentioned by the Queen during their journey. Along the way, they are forced to rescue Rios, who was injured and later arrested by immigration authorities. (PIC episodes: "Watcher", "Fly Me to the Moon")

She later joined the crew at a pre-launch gala for the Europa Mission to observe Renée Picard, Jean-Luc's distant ancestor, able to socialize more freely without her Borg implants. (PIC episode: "Two of One")

Dr. Agnes Jurati, who had been involved in the Coppelius incident, had been possessed by the Borg Queen and was loose in Los Angeles. Teamed with Dr. Adam Soong, an ambitious geneticist, the Jurati-Queen intended to seize La Sirena with mercenaries Soong provided her to act as improvised Borg drones. (PIC episodes: "Monsters", "Mercy")

Seven and Musiker fought to defend the ship, but Seven was impaled through the stomach by one of the Queen's tentacles. The mind of Dr. Jurati, fighting for control of her body, eventually convinced the Queen to save her life with nanoprobes, returning Seven's Borg implants. (PIC episode: "Hide and Seek")

After Q returned them to their own time, Picard used his authority to give Seven a field commission of captain and command of the Stargazer to replace Rios, who had remained in the 21st century. (PIC episode: "Farewell")

Starfleet career

USS Stargazer

After Q returned them to their own time, Picard used his authority to give their leading authority on the Borg, Seven, a provisional field commission of captain and command of the Stargazer to replace Rios, who had remained in the 21st century. Following the reveal that the Borg Queen attacking the ship was in fact Jurati trying to get their help to deal with a threatening galactic event, Starfleet and Jurati's Collective made common cause to stop the destructive wave. (PIC episode: "Farewell")

USS Titan-A

Annika Hansen, 2401

Commander Annika Hansen, First officer of the USS Titan-A

Seven was commissioned by Starfleet as a commander, serving as first officer on the USS Titan-A under the command of Captain Liam Shaw. Dismissive of her Borg past, Shaw insisted that Seven use her birth name, being known by her subordinates as Commander Hansen. (PIC episode: "The Next Generation")

USS Enterprise-G

Following the destruction of the Borg, Seven met with her old crewmate, Captain Tuvok and Vice Admiral Kira, and offered to resign from Starfleet due to her rogue actions. Tuvok denied her resignation and revealed that Captain Shaw sent Command her officer review before his death, praising Seven for her loyalty and unorthodox approach. He recommended that she be promoted to captain upon their return to spacedock. Tuvok proudly promoted Seven and by 2402, she was given command of the rechristened USS Enterprise-G with Commander Raffi Musiker as her first officer, and Ensign Jack Crusher as her special counselor. As Seven took the Enterprise on her shakedown cruise, she was left to contemplate what to use as her command as compared to other Enterprise COs. (PIC episode: "The Last Generation")

Alternate timelines

25th century

Seven was then recruited by Captain Jean-Luc Picard of the USS Enterprise-E to help Starfleet infiltrate the Borg. (TNG - Hive comic: "Hive, Issue 2")

In 2385, Seven left Starfleet after it decided the fact the Borg were no longer a threat after a decade of non-threatening actions from them. Seven saw their decision as dangerously reckless. Seven then accepted a job as a researcher for the Daystrom Institute. (STO website: The Path to 2409)

In 2409, Seven refused to return to Starfleet despite the return of the Collective and the Borg attacks on Vega colony. However, at the request of Admiral Tuvok, Seven accepted the position of science adviser to Tuvok's fleet and was assigned to the USS Callisto. (STO video game: Delta Rising)

Seven of Nine STO

Seven of Nine in 2410

In 2410 the Callisto was destroyed by a malfunction in the automated defense system of a Federation outpost in the Delta Quadrant's Yontasa sector. Seven was able to disable the defenses and beam the survivors aboard the outpost. After being rescued by an Alpha Quadrant Alliance starship, Seven helped the crew re-enable the planetary defense grid on the Turei homeworld, foiling a Vaadwaur invasion. When the USS Voyager arrived in orbit after the battle, Tuvok asked her to rejoin Voyager's crew, and she accepted. (STO - The Delta Quadrant mission: "Revelations")


Seven in 2411

In the year 2411, Seven operated for the Fenris Rangers again. She followed up a report of Borg activity in the Traelus system when she and an Alliance vessel were pulled to Excalbia. The Excalbians put them through trials, alongside a construct of Michael Burnham, to help them decide whether to pursue the ideals of Good or Evil. (STO - J'Ula's Discovery mission: "The Measure of Morality (Part 1)")

The Excalbian constructs became sentient, and a construct of Seven of Nine, enhanced by Control's nanites into a powerful Borg Queen, threatened the Excalbians. Seven, Burnham and their allies defeated the constructed queen and her minions, allowing Seven to conclude her mission in the Traelus system. (STO - J'Ula's Discovery mission: "The Measure of Morality (Part 2)")

In an alternate timeline, "Admiral Seven of Nine" married The Doctor in the late 25th century. A renowned Federation scientist with political ties, she and the former EMH contributed research to the Phoenix Project. Both were compelled out of mutual respect for the countless hours of dedication and sacrifice devoted to the Pathfinder Project, years ago. (DS9 novel: The War of the Prophets)

In another alternate timeline, she remained a member of the Collective until late 2374, when an attack by Species 8472 liberated her and seven other members of Unimatrix Zero. They were subsequently rescued by the Vostigye ship Ryemaran, and Seven reasserted her identity as Annika Hansen.

In another alternate timeline, Species 8472 won the war with the Borg by using the Omega molecule to destroy approximately half of the Borg Collective while limiting the surviving Borg vessels to sublight velocity. As it had already moved beyond Borg space by this time, Voyager was not affected. In this timeline, Seven of Nine was never liberated from the Collective. It was believed that she was killed in the devastation caused by the Omega molecule. (VOY - Myriad Universes novel: Places of Exile)

In another alternate timeline, Annika Hansen was a member of Jean-Luc Picard's resistance cell, until Wesley Crusher staged a coup, which she joined. She was subsequently killed by the Klingons. (TNG - Myriad Universes comic: "Do Not Close Your Eyes")

In another alternate timeline in which Voyager took twenty-three years to return to Earth, Seven married Chakotay at an unknown time and died some time between the wedding and their return to Earth. Grief over her death caused Chakotay's own death in 2394. It was these events, along with Tuvok's insanity caused by Tuvan Syndrome, which caused Admiral Janeway to go back in time and bring Voyager home in 2377. (VOY episode & novelization: Endgame)

In another alternate timeline in which the Borg were not absorbed by the Caeliar Gestalt, Seven retained her Borg technology and link to the collective. When the Voldranaii attacked the Borg and started to purge the galaxy, Seven, operating undercover, was selected by the Borg Queen to be their ambassador again and to help Starfleet update their weapons. She confirmed the Voldranaii threat the Queen told them. When Starfleet realized the Borg's deception, Seven was coerced into betraying Starfleet when the Queen transmitted the Sentinel protocol to her. She was forced to give the Borg the prefix codes to all Starfleet ships, enabling the Borg to lower all the Starfleet ships' shields. Fortunately, Commander La Forge was able to disrupt the Queen's control over Seven.

Despite Lieutenant Kira Archer's and Seven's call to terminate herself, Picard kept her alive and under guard. She, Captain Picard, and Data then devised a plan to use Seven's filter technology and the nano-virus that the future Locutus created to stop the Borg. The three of them then beamed to the Borg Vinculum, where Picard allowed himself to be assimilated by the Queen. Seven then used her filter to save as many drones as she could. However, Seven was mortally wounded during the attempt, when Lieutenant Archer fired torpedoes at the Borg cubes. Seven then died onboard the Enterprise.
