Fan Casting Batman in Earth-6

Wayne Williams' father was a policeman who was shot and killed. He is framed for a crime he didn't commit, and vows revenge on "Handz", the gang leader who set him up. In prison, Williams befriends a scientist named Frederick Grant who teaches him how to "develop his mind", as well as sewing and bodybuilding. Williams needs money, so he becomes a wrestler under the name "Batman" and makes sure to never unmask in public. In a few short weeks, "Batman" has become a big name in wrestling and is one of the wealthiest men in the world.
