Bruno Mannheim was a thug for the mob and Ace of Clubs owner Ron Milano. He made counterfeit money and mugged Chloe Sullivan along with AJ, stealing Chloe's bag and getting a whack from Lois Lane before leaving in his car. Bruno returned to the Ace of Clubs and got a drink from new bartender Jimmy Olsen, who asked to get an advance on his pay from Milano. Ricky then came to get Bruno because Milano wanted to see him, but when Milano began to mock Bruno for the mugging, Bruno turned on him, shooting him dead with a silenced gun in the backroom of the Ace of Clubs when Milano said that they were going legit. He then took over Milano's business and announced that they were first going to get rid of the heroes, starting with Stiletto.
When Jimmy came back into work late holding his camera, Bruno took it off him and recognized the photos of Chloe and Lois as Stiletto, and beat Jimmy for information before knocking him out. He was then in the backroom seeing through the counterfeit money when Clark Kent super-sped in. Kryptonite was being used on the counterfeit money, however, and weakened Clark enough that Bruno could punch him to the floor and beat him. Lois, as Stiletto, jumped down and knocked Clark away in time. As Bruno went to shoot her, Clark jumped in front of Lois, blocking her from danger. Jimmy came in and was able to take Bruno down.
Later, he was incarcerated at the Stryker's Island Penitentiary. Two years later, Gordon Godfrey gave him a book that changed Brunos life - the Crime Bible. Later, Bruno was "visited" by Batman because he knew about Brunos connection to the Intergang and tried to find out Joe Chill whereabouts.
