History
Initially working in the cause of justice just like the first Electrocutioner, Lester Buchinsky became a criminal and mercenary. Overly reliant on his ability to generate electricity, the Electrocuioner has faced (and been defeated by) Batman, Robin, and Nightwing. In at least one scheme, working with Cluemaster to steal an armored car full of money, Spoiler works to oppose him. Ironically, Spoiler would prove to be Cluemaster's daughter. The stupidity of Lester's second partner, a hulking brute with delusions of intelligence, would also hamper their plans. For a time, Lester was frequently seen in the employ of Bludhaven crime boss Blockbuster (Roland Desmond).
In Infinite Crisis, Lester became a member of the Secret Society of Super Villains.

In "Rise and Fall" storyline, Green Arrow is still hunting Electrocutioner those who worked with Prometheus, keeping secret his murder of the man as the rest of the JLA tries to track him down. Green Arrow confronts the Electrocutioner, who set off the device that devastated Star City in Justice League: Cry for Justice. He's close to killing the man when Black Canary stops him and in their argument, Canary realizes what Green Arrow did. Electrocutioner escaped from Green Arrow's rage to bring Electrocutioner down. Although Electrocutioner was defeated and horrifically injured by Speedy. Green Arrow's arrival convinces Speedy that killing is not the answer and the two archers took Electrocutioner into custody.
