A child prodigy, Bruce Banner grew up in an abusive household, one that would have a profound long-term effect on his psyche. An introverted child, Bruce was ill-equipped to deal with the outbursts of his father, who called young Bruce a monster and terrorized both him and his mother. Bruce developed a multiple personality disorder, shunting aside and repressing all of his negative emotions when the trauma bacame too much to take. This cycle of abuse continued until the day Brian Banner slew his wife in a fit of rage. Thereafter, Bruce was shuttled from relative to relative, and grew ever more socially awkward, even as his remarkable intellect became more apparent.
