Butch Gilzean

Butch Gilzean is a character in the DC Show Gotham and was the second-in-command to Fish Mooney in the Falcone crime family, before being brainwashed to serve her former umbrella boy Oswald Cobblepot/Penguin. He is played by Drew Powell.

Season One
Butch Gilzean works for Fish Mooney under Carmine Falcone and is loyal to her. He is first seen when Fish is beating someone up accused of stealing from her, but stops to tend to Harvey Bullock and detective James Gordon. Butch encourages her umbrella boy Oswald Cobblepot to give the man a beating, however tells him to calm down when he gets too over excited with the torture. It is eventually broken up by James Gordon who checks in on them and he gets Oswald to drop the bat.

When James turns up at the club to question Fish over the Wayne murders and the fact the wrong man is set up, he is knocked out and taken to a warehouse to be gutted. When Harvey attempts to save him and threatens Fish that if she kills him he will be forced to take her out, she orders Butch over the phone to hang Harvey up next to Jim and have him gutted, which Butch does. However Don Falcone arrives and shoots down Butch's men, and tells him that if Fish wants to kill police she has to come straight to him first. Falcone then leaves Butch alive and takes James away for a talk.

When Oswald reveals Fish's plans to takeover the crime family, her and Butch are taken away to be taught a lesson. Butch escapes and rescues Fish and they head back to the club to confront Oswald. But Carmine's hitman Victor Zsasz arrives with his henchwomen and chases down the pair of them. Butch helps Fish escape through a window but is captured by Victor. Over the next week he is taken to Victor's basement, tortured and brainwashed to serve Oswald. Butch is returned to Oswald in order to help run the night club.

Sometime later Fish returns to Gotham and makes an alliance with Don Sal Maroni to kill Carmine Falcone so they can rule Gotham. Carmine is strung up along with Gordon and Cobblepot to be killed and Butch is happy to reunite with Fish, although he is confused due to his conditioning and goes to lie down, which makes Fish angrier at Cobblepot for Butch being hurt. When a bloody war breaks out after Fish kills Maroni, she faces off with Cobblepot on the warehouse roof. Butch arrives armed, but conflicted over who to shoot he ends up shooting both Fish and Cobblepot. Butch collapses and an injured Fish comforts him, but she ends up being pushed from the roof by Cobblepot and presumably killed.

Season 2
A month after Mooney's death Butch continues to serve Cobblepot in his crime family after Falcone left town after the mob war.
