Garbodor did not originate from fanon, and the information on this page may not be entirely accurate to their canon. You may read more about this subject in the context of their canon on the following wiki(s):
Garbodor (Japanese: ダストダス Dustdas) is a Poison-type Pokémon. It evolves from Trubbish starting at level 36.
Garbodor has the appearance of a pile of trash spilling out of a large, torn garbage bag. It has a round, lumpy body that is mostly tan with blue and pink lumps. Its head has the appearance of the tied end of a garbage bag that has been ripped open and trails down like a cape. It has two appendages that look like clumps of garbage coming from its head. Its large, round eyes have small pupils, and when it opens its mouth, its large, triangular teeth can be seen. Garbodor has two long arms made of garbage that are held together with piping, and fingers also made up of piping material. It has one finger on its left hand and three on the other. It also has flat, dumpy feet.
Garbodor is able to spray poisonous gas and filth from its fingertips, but only from its right hand. It also finishes off opponents by subduing them with its left arm and spewing an awful-smelling toxic gas from its mouth. Garbodor prefers to live in unsanitary places such as garbage dumps. Garbodor inhales garbage, which then becomes part of its body.

Garbodor shares similar traits to Muk and Weezing. All three Pokémon are pure Poison types with a single pre-evolution, roughly the same base stat totals and evolution levels, and appear to be based on a different kind of pollution; Garbodor being land pollution.
