Hulk

Following his accidental exposure to gamma rays while saving the life of Rick Jones during the detonation of an experimental bomb, Banner is physically transformed into the Hulk when subjected to emotional stress, at or against his will. This transformation often leads to destructive rampages and to 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 alter egos, from a mindless, destructive force childish, angry, and destructive. When Banner transforms into the Hulk his physical capabilities are greatly enhanced, but his mental faculties regress to a childish state. He has trouble remembering things, is extremely emotional, and lacks foresight.
