Caleb Green was a member of the Church of Blood. He was also the son of the late William Green, an employee of Queen Consolidated.


In 2008, Caleb watched on and pleaded as his father physically abused his mother. He continued to watch in horror as his father shot his mother in the head, followed by himself. He proceeded to weep.[1]

Member of the Church of Blood

Years 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.[2]

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.[3] This led to him successfully being injected with Mirakuru, ultimately bleeding from the eyes due to it.[4]

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[5] for the Queen Mansion.[6]

Vengeance on Oliver Queen

He sat for a while in the main room, looking at his father's clock card, before deciding to track him down. Caleb intercepted Oliver outside of Queen Consolidated. He threw punches at him while on the ground, before throwing Oliver in to Champion Sports. Cops began surrounding Caleb, but he simply killed some of them. Before he could continue, Oliver came in with a baseball bat. Following that breaking, Oliver began to use a recurve bow. An arrow was shot in to his shoulder, causing him to openly decide to make Oliver suffer.[7] However, before he could do much, Roy Harper intervened in his vigilante outfit. More police appeared and surrounded the fight, but they were hindered by Caleb, who had picked up a car and threw it at them, escaping in the confusion.[8]

Powers and abilities


  • Peak of superhuman physical condition: After Caleb was injected with the Mirakuru, his physical capacity was increased in terms of strength, durability, stamina, speed, senses, reflexes, and agility, in addition to an accelerated healing factor.
    • Enhanced strength: Due to the Mirakuru serum, Caleb is much stronger than a normal human.[5]
    • Enhanced speed: Due to the Mirakuru serum, Caleb is able to move much faster than a normal human.
    • Enhanced durability: Due to the Mirakuru serum, Caleb is able to take more damage than a normal human, having been knocked down and even shot with an arrow.[7]
    • Enhanced reflexes: Due to the Mirakuru serum, Caleb is able to react much faster than a normal human, having caught a baseball bat being swung right at him.[7]
    • Rapid cell regeneration: Thanks to the Mirakuru serum, Caleb is able to heal much faster than a normal human. A wound such as one caused by an arrow hardly hindered him.[7]
    • Enhanced stamina: Due to the Mirakuru serum, which reduces the effects of fatigue, Caleb can exert himself at peak energy capacity greater than any normal human could, attacking others almost endlessly.[8]
