Bruce is a slender, nearly frail, looking caucasian male. He has unkempt brown hair and dark brown eyes which are normally downturned as though he was attempting to avoid making eye contact or avoid attention.

When turned into the Hulk, Bruce's skin changes into a vibrant green. His body grow impossibly large and grotesquely muscular. His clothing usually gets torn, he wears the remnants of the clothing that he was wearing as Banner before his transformation.
