Red Hulk (also known as Rulk or The IncREDible Hulk) was introduced in 2008 in "Hulk" (vol. 2) #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.
