The boyfriend of Oliver Queen's sister Thea, Roy Harper was abducted by Brother Blood's minions after investigating too deep into Blood's criminal plans. Harper was experimented on by Blood who aimed to perfect the experimental drug Mirakuru for Slade Wilson. Harper was eventually rescued by the Arrow and discovered that he had gained superhuman strength and stamina from the Mirakuru. Unable to control his new powers and rage that came as a side effect, Harper went to the vigilante for guidance.
