YMMV / Gotham S1E11 "Rogues' Gallery"

• Magnificent Bastard: Jack Buchinsky, aka the Electrocutioner, was the mastermind behind a string of bank robberies under the employment of Sal Maroni before being betrayed and subsequently arrested. Using his connections, he had himself transferred to Arkham Asylum under the falsified profile of "Jack Gruber", a textbook sociopath and rapist, then proceeded to experiment on the inmates using electroshock therapy intending to create the perfect minion, which he succeeds with two such individuals. When hero Jim Gordon investigates the electroshock cases, Buchinsky manages to evade detection. Using one of his minions to pose as an Arkham nurse to take the fall for the crimes, Buchinsky and his other minion manage to unlock his cell and escape. Upon his release, Buchinsky acquires his old electric weaponry and attempts to assassinate Maroni for his betrayal. With Maroni under protective custody, Buchinsky attacks the Gotham City Police Department directly, electrifying every metal surface and knocking out everyone in the building save for Gordon who defeats him by shorting out his equipment.
