Electrocutioner - Batman Arkham Origins

Lester Buchinsky was an egotistical street punk of limited intelligence and resourcefulness who was eager to make money and a name for himself as The Electrocutioner, among Gotham City's criminal underworld after losing in an underground pit fight. Lester used powerful Shock Gloves that he had created to appropriately electrocute his opponents to death. When he felt like being sadistic, Lester would send his victims into cardiac arrest, only to mockingly defibulate them and kill them once more.
