Described as a "repulsive brain-beast", Zomboid is a large, green creature with tentacles all over his body. Although it is unknown where Zomboid resides, it appears to be inside the head of a decaying zombie-like being. His only company is a giant insect with dozens of legs named Sluggon. He somehow captures Max and plans to feed him to Sluggon. However, Max uses his quick thinking to out-maneuver Sluggon and run passed Zomboid, forcing his sidekick to begin devouring him. While Zomboid is getting eaten, Max teleports to safety.
