First appearance: The Incredible Hulk #1 (1962)
An intellectual but introverted child, Bruce Banner was raised by his aunt following the tragic murder of his mother by his abusive father right in front of him. Bruce repressed this childhood trauma and grew up to become a highly regarded nuclear scientist at the United States Defense Department where he designed a new gamma bomb. It was during an experimental detonation of that weapon that Bruce, while attempting to rescue a civilian who had strayed into the area, was hit with a massive blast of gamma radiation. As a result, his pre-existing dissociative identity disorder now manifests as a physical transformation into the Hulk that he has yet to gain full control of.
The Hulk is one of the most powerful beings in the universe, with immense physical strength that increases with his rage. Throughout his storied history he has bested several of the Midnight Suns, including Ghost Rider, Iron Man, Spider-Man, and Wolverine. But he didn't fare so well against Lilith; now that she has turned him into one of her demonic thralls and imbued him with infernal power, recruiting him to your roster will be no small feat.
Hulk's offensive abilities grow more powerful with his Rage, which he gains whenever he takes damage from an enemy's attack. Rage is expended every time Hulk attacks, so taunting enemies into focusing on him not only keeps allies from harm, but also helps to sustain his Rage. Hulk doesn't lose Rage when he's healed by allies, but expends all of it when using his Always Angry ability to self-heal.
