Antonio Diego, under the name Bane, is one of Gotham's richest people, who just like his enemy, leads a double life. Out in the public, he's known for being rather cocky, and he barely interacts with anyone during events as he doesn't seem to be a people person. But in privacy, he runs a secret manufacturer that produces the venom that Diego uses and sells tanks of them at a high price, as he believes it's as valuable as it is addicting. To keep this from being known, Diego claims that he became rich due to winning the lottery, as dumb as it sounds for him.
