A Trampler is one of the larger GAIA Terraformers. The Machine's chassis resembles the body of a very large bovine bull, with a large head and a pair of large horns, a broad, powerful chest and shoulders, sturdy legs and hoof-like feet. Their mouth parts are composed of a pair of insectile pincers. They have two visual sensors on each side of the face, in the same position as a bovine's eyes. A power cell and two antenna-like structures sit on the lower back. Under the belly is a large, glowing, armored processing unit.
