Also known as 'The Mighty One', Grog earned his reputation by winning an arm wrestling contest in the local Greenskin pub. It didn't matter that his great intestinal fortitude allowed him to get his rather larger orc opponent swaying in his seat, the attendants still loved the contest, and the subsequent beating Grog took from the loser, which caused him to miss his next match on the pitch.

Being Grog's lil brother, Grezat was tried of constantly being in his brothers shadow, and constantly on the receiving end of his elder's beatings. He changed his name, and joined GGGG in the hopes of making a name for himself.
