Damien Darhk

Damien Darhk was a male Human.

Initially a member of the League of Assassins, Darhk was forced to flee after a falling out with Ra's al Ghul. Given that he lived before Ra's took over the league, he is at least 600 years old. He continued the League's ways, but through his own organzation called H.I.V.E.. As its leader, Darhk opposed the Green Arrow multiple times through agents, but the Arrow and his team did not connect the actions to Darhk. He send fellow H.I.V.E. member Milo Armitage to acquire Malcolm Merlyn's earthquake device, gave Gholem Qadir save haven to Markovia and hired another man to steal a file from A.R.G.U.S.

At one point, Darhk came into possession of a ancient idol which gained him the ability to perform magic. Many members of H.I.V.E.'s leadership who were dissatisfied with Darhk were now forced to accept his superiority. Darhk and H.I.V.E. eventually came to Star City in order to succeed with a H.I.V.E. operation called Genesis. Although the scope of Genesis is yet unknown it seems to result in the end of the world. At Star City, Darhk used his influence to get rid of the city's leadership to have the city sink into chaos, allowing him to take control unseen. While the Green Arrow found out about Darhk he tried to stop him but was swiftly defeated by Darhk's magic. Oliver tried to take down Darhk and his operation more than once but was defeated every time he came close to Darhk in combat. Eventually, Oliver Queen announced his intention to become mayor of Star City, which did not sit well with Darhk who needed the city in chaos. Damien initially tried to bribe and threaten Oliver into stepping down but Oliver remained determined. A feud between the two men ensued and when Oliver released Darhk's name, photo and occupation as leader of the group terrorising Star City to the media, Darhk retorted by ordering the assassination of Oliver's spouse Felicity Smoak, though Felicity was merely rendered terminally paraplegic. While trying to prevent Oliver from becoming mayor he also sent his wife Ruvé into the preelection.

In one of his tries to get rid of the Green Arrow, Darhk hired the hitman Lonnie Machin but later gave him up to the SCIS as Machin proved to be unreliable and chaotic. This caused a deep hatred for Darhk in Machin, eventually leading to Machin attacking Darhk's house and kidnapping Darhk's wife and daughter. Ironically Darhk's family was saved by Darhk's nemesis, the Green Arrow.

After finding out about Darhk's idol, Oliver and his team with aid of fellow heroine Vixen located the idol at Darhk's mansion at Skywoods. They launched an attack on Skywoods and with combined forces were able to steal and destroy the idol. Darhk, now powerless, was easily defeated by Oliver and taken into custody by the SCIS.
