Krumpa found his team of Chaos Renegades through an interesting sort of trial. He was always small, for an orc. Shorter and not as bulky as his comrades, he was usually found near the bottom of the Orc food chain. When he tried to sign up for an Orc Blood Bowl team, he was laughed off the pitch. But, lucky for him, he caught the eye of a different team entirely who was looking for the just the thing like Krumpa, and he proved that, while smaller then most orcs, he's just as sturdy, and just as willing to play as they are. He was happily accepted into the Renegades, and has served as one of the team's frontline for a long time, always excited to face down whatever team is in front of him next on the line of scrimmage.
