This ex-lineorc shied away from his duty as a punching bag, so the team took his helmet away and made him a thrower.

After "dying" in an early Rumblers match under very suspicious circumstances (accidentally punching himself in the face) and failing to regenerate, Bung was written off as a foolish recruitment gimmick and forgotten about. After the team lawyers received word that he had indeed survived the ill-aimed blow and was currently living under a bridge in the outskirts of Altdorf (mugging schoolchildren for their milk money) he was hauled back into practice and reminded of his contractual obligations.

Mog has become somewhat of a celebrity amongst the Rumblers fans after killing the Ruin Rains ogre Gra'kna with a well placed headbutt. The slogan "Just Mog It" has recently been seen on cheap bootleg tunics in backalleys near bloodbowl arenas. A broken neck hasn't slowed this toughguy down too much, and it's possible that the fused vertebrae have actually strengthened the patented Mog 'eadbutt.
