Following his accidental exposure to gamma rays during the detonation of an experimental bomb, Banner is physically transformed into the Hulk when subjected to emotional stress, at or against his will, often leading to destructive rampages and conflicts that complicate Banner’s civilian life. The Hulk’s level of strength is normally conveyed as proportionate to his level of anger. Commonly portrayed as a raging savage, the Hulk has been represented with other personalities based on Banner’s fractured psyche, from a mindless, destructive force, to a brilliant warrior, or genius scientist in his own right. Despite both Hulk and Banner’s desire for solitude, the character has a large supporting cast, including Banner’s lover Betty Ross, his best friend Rick Jones, his cousin She-Hulk, therapist and ally Doc Samson, and his co-founders of the superhero team the Avengers, etc. However, his uncontrollable power has brought him into conflict with his fellow heroes and others. Despite this he tries his best to do what’s right while battling villains such as Leader, Abomination, Absorbing Man and more.
