Hulk

Hulk, officially known as Bruce Banner in human form, is a character in the Marvel Universe, often seen in various iterations of the Avengers. Possessing a dual identity, Banner is a brilliant scientist who transforms into the Hulk under emotional stress, manifesting as a powerful, green-skinned, gamma-irradiated giant with immense strength. The Hulk has an alter ego that is simpler and more childlike in thought, while Banner is complex, conflicted, and brilliant. The Hulk's raw power is counterbalanced by Banner's intelligence and his deep-rooted fear of his own alter ego. He often battles against his own rampaging nature and the subsequent damage it causes, while also dealing with the disdain of others and his own self-acceptance. His relationship with other Marvel characters such as the Black Widow, Tony Stark, and Thor is intricate, ranging from allies to rivals depending on the circumstances.
