Bruce Banner (Earth-6457)

"Tony Stark and Bruce Wayne use their genius to save the world every other week. That's how they'll be remembered in history. Meanwhile, I – I who, forgive me, have just as much to contribute – will be lucky if my tombstone doesn't simply say "Hulk Smash.""

- - Doctor Bruce Banner

Doctor Robert Bruce Banner was a brilliant scientist who since a child suffered a rare disease that prompted his father, David Banner, in injecting temperamental-inducing nanomachines in his system in order to test his condition. When David's project was taken down by the military and Thunderbolt Ross, he turned to insanity and assassinated his wife, Rebecca. Raised by his relatives, Bruce found a job as a teacher at Culver University, where he worked closely with Ross' daughter, Betty. When Banner saved a lab assistant from being hit by a unstable experiment testing on gamma radiation, he was hit instead, the gamma, mixed with the nanomachines in his body transforming him into a rage-induced creature known as the Hulk. Without control of his form, Banner went into hiding by a always pursuing military under Thunderbolt's commands, as he is deemed a terrorist by the government. His acts prove the contrary, though, as he became a founding member of the Justice League.
