Mark "Buff" Bullswell is a boss in Dusk. He is the leader of the Bull Head Gang that has been terrorizing Lodow Town. Before forming the gang, Buff was a fighter for an underround fighting circuit . After causing so many injuries in the circuit, he was let go. Sometime down the line, he formed the Bull Head Gang with other fighters that were released from the circuit. Buff is the typical brawn over brains archetype. He rather let his muscles do the talking for him, and is not afraid to fight anyone who gets in his way.
