Gash is a brown minion and the overseer of the Dungeon of the Dark Tower. He is one of the oldest minions, having survived the second Overlord's death and the disappearance of the Third Overlord shortly before the Great Cataclysm in Overlord destroyed the Dark Tower. He fled to the Netherworld with the other surviving minions and waited there for a new master. When the Battle Rock Arena was completed, he assumed his role as overseer. If you want to fight in the arena, you must select a fight and talk with him. He nearly resembles the Guard Minions in Overlord. He wears a black executor mask and wields an axe.
- If you knock him to the ground, he will raise up and do a salute gesture like the minion guards in Overlord 2.
