As part of the Amazo's crew
After Sara Lance was pulled overboard her boat in to the ocean, the crew of the Amazo rescued her. "The Butcher" asked her as to why she was there, before taking her to a cell. Later in the day, he and another man went to take her somewhere but were intervened by Anthony Ivo, who claimed authority, taking her to the safety of his study.
Some time later, Ivo and his men took Oliver Queen to the supposed spot of the Hōzen. They were intercepted by Slade Wilson and Shado, who suggested a trade for Oliver. However, he was able to escape, with Sara in tow. They eventually escaped, causing Ivo to kill "The Captain" and promote "The Butcher" to the position of captain.
Not long after, they followed Oliver and company to a Japanese submarine, finding that they'd used some of the Mirakuru on Slade. Ivo took them to shore, forcing Oliver to choose between Shado and Sara's lives, subsequently killing Shado despite Oliver refusing to choose. Suddenly, Slade appeared, injuring and killing some men, causing them to flee.
Soon following, they captured Anatoly Knyazev. "The Butcher" assisted Ivo to extract his eye, but they were distracted by a fire lit by Oliver on the beach of Lian Yu. He was sent to capture Oliver, which he was successfully able to. They began to interrogate Oliver with a truth serum. Oliver falsely revealed Slade and Sara to be in the engine room of the freighter, and so he was sent along with all of his men to find them. A fight eventually ensued upon the freighter, which he survived. He ordered Slade to get in to a prison cell. When he didn't comply, he shot him, though due to the Mirakuru in his body, it had no effect. Slade subsequently crushed his head in his hands.
