The second Electrocutioner was a vigilante, his name and motives were not revealed but he considers himself a hero. He first appeared in Crescent City and began to kill criminals and people whom he believed escaped justice. Because of this he ran afoul of Batman who doesn't approve of his actions. However, this Electrocutioner didn't wish to fight Batman since he believes they are on the same side. This guy was killed by the Vigilante.

Lester Buchinsky

Lester became the third Electrocutioner after his brother's death. He had the same powers as the previous ones and tangled with Batman, Robin and Nightwing. He was pretty lousy at first: working with Cluemaster to pull a heist on an armored car filled with money but Cluemaster's own daughter Stephanie Brown AKA Spoiler stopped him. He then partnered with a giant brute who believes himself to be intelligent and frequently got in the way of his schemes. He seemed to have gotten past that stage and is now under the employ of Blockbuster in Bludhaven.

In Animation

Electrocutioner had made an appearance in JLU. He was first seen in the meta-brawl where Wild Cat used to fight with other Meta Humans before Green Arrow and Black Canary stopped him. He was later a member of Grodd's Legion of Doom and was present when the Flash and Lex Luther accidentally switched minds. He later appeared in the episode 'Alive'.
