The Hulk (Dr. Robert Bruce Banner) is a fictional character, a comic book superhero appearing in publications from Marvel Comics. Created by Stan Lee and Jack Kirby, the Hulk first appeared in The Incredible Hulk #1 (May 1962). He has since become one of Marvel Comics' most recognized characters.

After physicist Dr. Robert Bruce Banner was caught in the blast of a gamma bomb he created, he was transformed into the Hulk, a raging monster. The character, both as Banner and the Hulk, is frequently pursued by the police or the armed forces, often as a result of the destruction he causes. While the coloration of the character's skin varies during the course of its publication history, the Hulk is most often depicted as green. In forty years, he has battled virtually every hero and villain in the Marvel Universe. He has been featured in a number of animated series, a feature film directed by Ang Lee, and a television series with spin-off television movies starring Bill Bixby as Banner and Lou Ferrigno as the Hulk.
