Batman's penis was Batman's penis. It was different from Bruce Wayne's penis as it was dark, scary, it had a cape and two pointy things on top. Batman's penis was not to be trifled with since it was one of few items in the world that could counter an attack by the Joker's pencil.
It also had the world's most resilient crimefighting helmet.
Behind the scenes[]
Batman's penis was portrayed by Jason Acuña in cut-content of The Dark Knight. Critics have said it was an Academy Award-deserving performance.
