Early lifeCaleb Green was born to William Green and an unnamed woman in Starling City.In 2008, Caleb watched on and pleaded as his father physically abused his mother. Caleb continued to watch in horror as William shot his mother in the head, followed by himself. He proceeded to weep over their bodies.
Member of the Church of BloodYears later, Caleb was approached by a mysterious man named Abel. Abel offered him a better way, a "Church". He took him to an abandoned church, which Caleb was unimpressed with, until the man revealed the multitude of other members, pointing out their leader, Brother Blood.
Caleb admitted to Abel that he was probably not a "true believer" as they had hoped, though Abel took him to a room in which there was a Mirakuru soldier chained up. He mentioned that they would still need soldiers in their cause. This led to him successfully being injected with Mirakuru, ultimately bleeding from the eyes due to it.Once he woke up, Caleb escaped from his constraints. He went after Abel, who'd been the one to inject him. Proudly claiming to be strong enough to kill Oliver Queen, he snapped Abel's neck and escaped to the Queen Mansion.
Vengeance on Oliver Queen
He sat for a while in the main room, looking at his father's clock card, before deciding to track Oliver down.
Caleb intercepted Oliver outside of Queen Consolidated. He threw punches at him while on the ground, before throwing Oliver into Champion Sports. Cops began surrounding Caleb, but he simply killed some of them. Before he could continue, Oliver attacked him with a baseball bat. When that broke, Oliver began to use a recurve bow. An arrow was shot into Caleb's shoulder, causing him to openly decide to make Oliver suffer. However, Arsenal intervened. More police appeared and surrounded the fight, but they were hindered by Caleb, who picked up a car and threw it at them, escaping in the confusion.Caleb broke into the Queen Mansion and sat there for a while, looking at pictures. He later tracked down Laurel Lance. Under the guise of an old high school friend, Green attempted to learn of Oliver's whereabouts but Laurel stated that she did not know where he was. He then gave her a piece of wood from the Queen Mansion to give to Oliver.
Caleb eventually kidnapped Laurel from her apartment and brought her to the Queen Mansion. When Oliver arrived, Caleb knocked him out and tied him up as well. When Oliver awoke, Caleb deduced his identity as The Arrow. He then revealed his plan to burn the mansion down with Oliver and Laurel in it.
Oliver managed to escape and the two fought, with Caleb destroying the Mirakuru cure that Oliver had made for him. The mansion eventually collapsed, with Caleb fatally wounded after being impaled by debris.Oliver and Laurel survived and the former attempted to administer aid to Caleb, only for the latter to claim it was too late. Before dying, Caleb claimed that no matter what Oliver did, he would always be the same selfish, inconsiderate person that he was before being stranded on the island and that would have to live with that. Caleb then succumbed to his injuries.
