The Devil Hulk or Immortal Hulk is the result of the Hulk needing a father figure. While the character's physical appearance varies, he is always depicted as having glowing red eyes and reptilian traits. The new form of the Devil Hulk is the result of Banner and Hulk having been through different deaths and rebirths. This incarnation is articulate, smart, and cunning, and does merciless attacks on those who do harm. Unlike the other Hulk incarnations, the Devil Hulk is content with waiting inside Bruce. If Bruce is injured by sunset, the Devil Hulk will emerge with his transformation being limited to night-time. Thanks to the Devil Hulk side and Banner working together, the Devil Hulk can maintain his form in sunlight.
