The Hulk is a fictional character, a superhero that appears in comic books published by Marvel Comics. The character was created by Stan Lee and Jack Kirby, and first appeared in The Incredible Hulk #1 (May 1962). Throughout his comic book appearances, the Hulk is portrayed as a large green humanoid that possesses near limitless superhuman strength and great invulnerability, attributes that grow more potent the angrier he becomes. Hulk is the alter ego of Bruce Banner, a socially withdrawn and emotionally reserved physicist who physically transforms into the Hulk under emotional stress and other specific circumstances at will or against it; these involuntary transformations lead to many complications in Banner's life. When transformed, the Hulk often acts as a disassociated separate personality that hates Banner. Over the decades of Hulk stories, the Hulk has been represented with several different personalities based on Hulk and Banner's fractured psyche, ranging from mindless savage to brilliant warrior, and Banner has taken control of the Hulk's form on occasion. Banner first transforms into the Hulk after being caught in the blast of the gamma bomb he invented while saving Rick Jones, a youth who had wandered onto the testing range

Red Hulk (also known as Rulk) was introduced in 2008 in Hulk #1. The Red Hulk was created to be an uninhibited, tactically intelligent adversary to the Hulk. Although Kenneth Johnson, the creator of the 1970s TV series The Incredible Hulk, had suggested a red Hulk for that adaptation decades earlier, Marvel Editor-in-Chief Joe Quesada proposed the idea for the comics to debut a red version of the character, whose human identity was a secret. Initially, Red Hulk's identity was unknown both to the characters in the story and to the reading audience.
