Lester Buchinsky's brother was the original Electrocutioner, but was killed in combat. With the mantle empty, Lester stepped in and took up the title. He wasn't very effective at first and that showed in his encounters with Batman, Nightwing, and Robin. He teamed up with Cluemaster for a simple robbery, but was stopped by Stephanie Brown as the Spoiler. He didn't fair much better as he constantly got in the way of the success of his partners.
Lester Buchinsky was created by Chuck Dixon in Detective Comics #644
He eventually became more skilled as a villain and has worked for Blockbuster. He was active in Bludhaven during that time

In the loosely-based Batman game for the Nintendo, Electrocutioner was the boss of stage 3. He had an electric sword-arm that was used to fling arcing high-voltage projectiles. Along with Killer Moth and Firebug, he was a supervillain working for The Joker.
Much to everyone's surprise, Electrocutioner was announced as one of the eight assassins in Batman Arkham Origins. He was first noticed in the mobile game trailer, and was then officially announced and given his own trailer a few day's later. His trailer first debuted at Comic Con 2013.
In the game, Electrocutioner is meant to be more of a laughable assassin rather a hard one to beat. He first appears on the Penguin's boat "The Final Offer", taunting Batman. Batman then easily knocks him unconscious in one hit. Later in the game he and the other assassins are at a meeting hosted by the Joker. Electrocutioner is shown playing games on his phone rather than listing, to which Joker breaks the phone and starts shooting wildly at him, eventually pushing him out the window, killing him.
