Ghosts

"I'm the one who controls– what do you people call them? The Ghosts?"

- Damien Darhk to Star City administration

The Ghosts are agents of H.I.V.E., who act as the terrorist group's grunt soldier force, security guards and representatives.

Overview
H.I.V.E. operatives were nicknamed "Ghosts" by the media of Star City, and later Team Arrow, who faced the difficulty of targeting the movements of the terrorist organization, since its agents with uncooperative and had a tendency to kill themselves (usually with special poisonous capsules hidden in their mouths), rather than allow to be tortured. H.I.V.E. agents would quickly disappear after a successful mission, never revealing the secrets of their leadership, and their own identities were kept secret, if not erased from any database, thus becoming metaphorical "ghosts" of people long thought dead or non-existent, like Andy Diggle.

The Ghosts use modern weaponry and high-tech equipment. Their operators wear bulletproof vests and use advanced firearms and grenades. Their unique uniforms are adorned with a pattern of hexagons, resembling a honeycomb of a beehive, painted on a gray-colored fabric.

History
H.I.V.E. started using these operatives long before the confrontation with Oliver Queen. For example, in 1975, Damien Darhk and two of his Ghosts went to a weapons sale held by Vandal Savage in Norway, planning to buy a nuclear warhead from him. H.I.V.E. put in an initial bid of $100 million, but were outbid by Martin Stein, which led to a confrontation between two men. Stein's associate Mick Rory started to get angry with Damien and then threatened him, forcing Savage to intervene. As a fight ensued, Damien and the Ghosts left the premises of the Norwegian military storage facility.

After Floyd Lawton was incarcerated for threatening the lives of his family, Mina Fayad approached him as a representative of H.I.V.E., and offered Lawton money to assassinate Andrew Diggle, though - unknown to Lawton - Diggle survived the attempt as H.I.V.E. had secretly replaced Lawton's bullets with non-lethal rounds. Diggle himself ended up becoming an agent of H.I.V.E., serving as one of its Ghosts.

After Ra's al Ghul's failed attempt to destroy Star City and Damien Darhk, H.I.V.E. soldiers began attacking the city in waves, receiving their nickname of "Ghosts". The Ghosts brought Alvarez to Damien Darhk for execution, and later assisted him in the attempt to blow up Star City's central train station.

To ensure the security of the identities of his Ghosts, Darhk sent Quentin Lance on a mission to erase their names from governmental databases. Lance went through with the operation, but managed to convince Darhk to tell him about Andrew Diggle, whose name had been on the list of Ghosts given to him.

A division of Ghosts guarded the imprisoned Ray Palmer. Team Arrow managed to successfully rescue Ray, although Oliver barely managed to escape being strangled to death by chains under control from Darhk's telekinesis.

Green Arrow and his team continued to plague H.I.V.E.'s operations in Star City culminating in a surgical strike against the HQ of the Ghosts by the Green Arrow and his team in an effort to rescue Andrew Diggle, who the team had found out was alive. The Ghosts fought Team Arrow but were overpowered and the team escaped with Diggle. H.I.V.E. later raided an A.R.G.U.S. facility to steal a chemical bomb, only to be confronted by Team Arrow, who disarmed the Ghosts of their guns with a magnetic arrow. The Ghosts fought the team but before an outcome could be revealed, The Flash whisked the Team away to deal with problems in Central City.

In an act of revenge Darhk personally led a squad of Ghosts to attack Oliver's Holiday Party, and took John Diggle, Felicity Smoak, and Thea Queen. However, Laurel Lance and Malcolm Merlyn interfered and saved Oliver's compatriots. Darhk immediately left the scene, sending his partners to a safe location, and fought with Merlyn while the rest of Team Arrow fought Darhk's Ghosts, resulting in Damien's near death when Merlyn blew up their hideout. The surviving Damien Darhk sent Ghosts to kill Queen. They attacked Oliver's limousine, firing upon him and Felicity and leaving Oliver injured and Felicity unresponsive.

Several Ghosts intercepted Ray Palmer when he entered their hideout to destroy a weapon in their possession. Ray defeated them all, before he was taken by Rip Hunter to be made a part of his team.

A number of Ghosts were killed by Lonnie Machin as a "message" for the H.I.V.E. after Damien Darhk refused to hire him as his partner.

After his son, William was kidnapped by Damien Darhk and Malcolm Merlyn, the Green Arrow hunted down the Ghosts mercilessly, trying to force them to give him information on Darhk's location, to no avail.

A group of Ghosts, along with Malcolm Merlyn's supporters from the former League of Assassins, had assaulted a weapon truck, only to be interrupted by Green Arrow, Spartan and Andy Diggle. However, the attack was a ruse, needed to cover up Malcolm Merlyn's attack on the Arrowcave.

Andy Diggle and the other Ghosts accompanied Damien Darhk after he freed himself from imprisonment and, in a bid for power, eliminated other high-ranked H.I.V.E. members, seizing the control of organization for himself. The Ghosts were also sent to guard H.I.V.E.'s underground facility "Tevat Noah", which was a part of the Genesis project. They made sure Thea Queen wouldn't escape said facility after she ended up there with her boyfriend Alex Davis.

The Ghosts acted as guards for the Tevat Noah facility the "home in the new era" that H.I.V.E. created for its members. They also served as security for H.I.V.E. leaders like Malcolm Merlyn, who tried to persuade Thea Queen that staying in the facility was in her best interests. However, even the Ghosts' unbreakable ability to protect the organization's secrets was proven moot before the wrath of Lonnie Machin, who has hunted down and tortured many Ghosts to find the location of Damien Darhk. Infiltrating the facility, Machin has stunned a Ghost, and sought to sabotage Telvat Noah's life support systems.

Danny Brickwell and Michael Amar also led a group of Ghosts to hunt down Noah Kuttler, the Calculator, who was considered to be the only person capable of hacking A.R.G.U.S.'s Rubicon protocol. The Ghosts were unsuccessful as Kuttler himself gunned down some of his pursuers, while Oliver Queen and John Diggle handled the rest. After the Calculator and his daughter, Felicity Smoak, came close to shutting down the Rubicon protocol, the Ghosts attacked their location once again, but were repelled by A.R.G.U.S. forces.

Two Ghosts accompanied Malcolm Merlyn when he was hunting for Lonnie Machin. At Merlyn's orders, they took hold of the distraught Thea Queen, placing her under guard, and later fought off Green Arrow and Spartan who tried to save her. They also stood guard at H.I.V.E. headquarters, as Damien Darhk and Ruvé Adams discussed their plans to take the Rubicon protocol back from Team Arrow with the help from Cooper Seldon.

The Ghosts accompanied Damien Darhk during his visit to Felicity Smoak's apartment, when he threatened Donna Smoak. Green Arrow and Spartan intervened and had to fight off the Ghosts, only to see Darhk escape. They later assaulted the Arrowcave and assisted Darhk during his final showdown against Oliver Queen and the people of Star City.
