Garbodor is a massive, monstrous Pokémon that appears have mutated from the toxins within a garbage bag. It has what seems to be a broken trash bag on its head, and covering the top part of its body. It has two ear-like clusters of garbage protruding from the top of its head. It has large round eyes and a gaping fang-filled mouth. The bottom part of its body is made entirely of filthy grayish brown garbage-like slime. It has patches of green and pink within the slime, and two arm-like appendages with metallic tubes sticking out. It has short stubby feet.
Garbodor can learn Sludge Bomb and Gunk Shot, among others. It belches poison gasses from its mouth. By eating garbage, it creates new kinds of toxic gasses inside its body.
