The Gigatron is the first boss encounter in Pac-Man World 3. It is piloted by Erwin, and resembles a spacecraft; it is equipped with a super laser and two k-tron dispensers.
The Gigatron features opposing parts that bulge out of the front and back of the vehicle. These parts fall off after the player jumps on them several times; after they fall off, the player must jump onto the center cockpit to damage the Gigatron.
