- "I got into politics to make a difference, right, to- to make the world a better place, and Ruvé has shown me that the only way to do that is to start over."
- —Alex Davis on joining H.I.V.E.[src]
Alex Davis (died 2016) was a political strategist employed by Oliver Queen and the boyfriend of Thea Queen. After Oliver dropped out of the mayoral elections campaign, Alex joined the office of the winning mayor, Ruvé Adams. In service of Ruvé, he was brainwashed with the help of suggestion pills, turning him into a loyal member of H.I.V.E. and a denizen of Tevat Noah. He was ultimately killed by Lonnie Machin, who saw Alex as an unwanted influence in Thea's life.
Oliver Queen's mayoral campaign
Alex was employed by Thea Queen to help her half-brother, Oliver, during his mayoral candidacy. When he met Oliver, he recommended that he distance himself from Laurel Lance in order to maintain a clean image. However, he refused to do so and Davis gave up, remarking that he would be paid either way.
After going over their campaign itinerary with Oliver, he asked Thea out on a date which she rejected citing her already complicated life. The next day, he handed some campaign forms for Thea and she asked him out for a drink which he accepted.
Alex organized a speech at the Patrolmen's Benevolent Association Gala for Oliver to give in order to help get the support of the police for his campaign. He also advised against Oliver's idea for a bay cleanup program since he believed it wouldn't attract voters. He attended the gala and watched Oliver's speech. Later on a date with Thea, he witnessed Thea beating up another man at the bar. They later met up again at the bay cleanup event where Thea asked him to be patient with her.
At Oliver's bay cleanup, Alex told him that Star City seemed to like this idea and that his approval rating was up 10 points. After Damien Darhk stormed the campaign holiday party, Alex held off the press and police for Oliver.
Because Thea was losing control of her bloodlust, she came to Alex and wanted to break things off with him. Alex reminded her of how strong she was in face of so many tragedies which convinced her to stay with him.
Alex called Oliver to meet. Oliver instantly appeared surprising Alex; Oliver joked that he used a secret elevator to get there so fast. Alex told him that another candidate was about to wage a rival mayoral campaign, Ruvé Adams. Unbeknownst to Alex, Oliver already knew her as Damien Darhk's wife.
Alex was unable to attend Oliver and Ruvé's mayoral debate because his mother had to go to the hospital for surgery.
Working for Ruvé and involvement with H.I.V.E.
When Oliver was forced by Damien Darhk to drop out of the mayoral race, Alex was disappointed as he knew that Oliver had a big shot at winning and they'd worked so hard to get that far. He asked Oliver for an explanation, which he couldn't give, and Alex accepted this gracefully and left. Shortly after, he was offered the position as the Chief of Staff of Oliver's former opponent, Ruvé Adams, who became the new mayor after winning the election by default. Thea tried to get him a job as the head of PR at Palmer Technologies instead but was unable to.
For his new position, he was attacked by the vengeful Evelyn Sharp who had been posing as the Black Canary. Also because of his affiliation with Ruvé, Alex earned a spot in the Ark. He was given pills - which Ruvé told him were vitamins - that made him susceptible to suggestion and thus willingly agreed with H.I.V.E.'s plans. While on a getaway with Thea, he took her to the Ark without her knowledge. He was later electrocuted and killed by Lonnie Machin, who saw him as an unnecessary influence for Thea. His death apparently saddened Malcolm Merlyn who claimed to have approved of his relationship with Thea.
Five months after his death, Alex's killer Lonnie Machin was finally brought to justice when Oliver took him down during Machin's attempt to use a bomb to destroy half of Star City. Oliver knocked Machin out and left him for the police.
