One of the few superhumans to undergo a permanent physical change, Brawn was four metres tall, completely hairless, with dark-blue skin. It's widely believed that Brawn had sub-normal intelligence to match his ferocious temper, though some experts maintain this was a media-created fallacy and that Brawn's intelligence was at least average. Regardless, it is said that he would occasionally show compassion to his intended victims.

As a super-villain working on his own Brawn never had much success, and spent more time in prison than out of it. However, once recruited by Ragnarök and teamed with Slaughter, Brawn finally moved into the big leagues.

Costume:
For most of his "career", Brawn wore only a pair of skin-tight trunks. It is believed that this was primarily because of his great size - a four-metre-tall man cannot easily find clothing to fit him!
