Robert Bruce Banner is better known in the world as the Incredible Hulk. He is a brilliant scientist who can transform into an immensely strong monster when he gets angry or when his heartbeat is very rapid. This became possible after Banner was involved in a lab incident involving gamma radiation. When he transforms, his skin turns green and he has superhuman strength, durability, speed, endurance, and stamina. He can bring out the Hulk by will. The Hulk is very aggressive and stubborn, but good-hearted because he wants to help people with his superpower.
