Gish's attack pattern is similar to that of Monstro II. However, instead of a blood beam, he attacks with exploding projectiles that leave behind puddles of tar that slow down the player. Instead of Monstro II's Sucker-spawning attack, Gish spawns two smaller Clots. Unlike with Monstro II, his first stomping attack does not produce any projectiles.
- Gish is a character from Edmund's game, Gish. Gish was also an unlockable in another of Edmund's games, Super Meat Boy and the free flash game Meat Boy, and appeared as a part of customization in his game Host.
