Golem is the gatekeeper of the village where Mog and Chocobo live. He does not allow anyone to leave until they beat him in a race. Golem keeps a piece of the Blue Crystal, and was prompted to follow the two after his defeat in a race.
Golem uses the ability "Grip-Up", which enforces stronger control for the vehicle. He drives the Rockin Roller V8, which is a bit slow but a really steady vehicle.
Golem appears as different types of enemies in the dungeons. Two particular ones; named Gotton and Gauche, also appear as inhabitants of the village, taking care of the nut-giving tree. Gotton encourage Chocobo to use up feathers to help the tree grow so that later on Gauche may give him nuts from the tree to use for mixing with claws and saddles or for general use.
Golem reappears in Chocobo Tales. He is the guardian of the forest where the Earth Crystal is kept. Chocobo had to fight a card duel against him to stop Bebuzzu. As a dueler, he speaks in a caveman-ish fashion.
