- "Don't call us a gang. Don't call us criminals. We are the law. We are the future. Gotham City belongs to the Mutants. Soon the world will be ours."
- ―Mutant Leader[src]
The Mutant Leader is arrested and brought to prison, but when the mayor tries to negotiate with him, the Leader murders him without second thought. Following a plan with Batman, Commissioner James Gordon deliberately releases him, and he finds the entire Mutant Gang assembled near a sewer outlet. Batman then ambushes him, leading to a bloody rematch. Despite his physical superiority, the Mutant Leader is no match for Batman's strategic mind; he chose the mudhole to slow the leader's movements, and he inflicts several major wounds. Eventually, Batman overpowers the Mutant Leader, and the Mutants disband into smaller gangs.
The Mutant Leader seems to be in peak physical condition, as he manhandles an older version of Batman in their first fight. He is bigger than Batman, very savage, and incredibly strong and fast. Additionally, his nails and teeth appear to be filed to points, and his skin appears a greyish hue. It remains unclear as to whether or not he possesses a metagene, which would make him a true mutant.
