Legion of Vengeance: Rage

Rage = Bane + Hulk

Real Name: 

Origin: During the experimental detonation of a gamma bomb, scientist Bruce Banner rushes to save teenager Rick Jones who has driven onto the testing field; Banner pushes Jones into a trench to save him, but is himself hit with the blast, absorbing massive amounts of gamma radiation. He awakens later in an infirmary, seeming relatively unscathed, but that night transforms into a lumbering grey form that breaks through the wall and escapes. A soldier in the ensuing search party dubs the otherwise unidentified creature a "hulk". 

Banner flees to the Caribbean Republic of Santa Prisca where he is detained and sent to prison. The leader of the nation offers Banner sanctuary as long as he serves as a doctor for his cabinet. Banner agrees, but the whole time he is trying to find a way to chemically temper his transformations.

He succeeds in creating a serum called Venom. Through injections, Venom allows controlled transformations while keeping the target's intelligence intact.
 
Powers: Rage possesses the potential for limitless physical strength depending directly on his emotional state, particularly his anger. His durability, regeneration, and endurance also increase in proportion to his temper.
