Garbodor is a Pokémon which 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; one held together with piping, with fingers also made up of piping material, and the other held together with rebar. 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. The toxic liquid from its right arm is so virulent, it can kill a weakened foe instantly. If that filth is blocked, its arm can swell up, causing it considerable pain and discomfort. It can also finish off opponents by belting 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, where it devours garbage in order to grow larger. Consuming garbage also allows Garbodor to create poisons in its body, the type of which depends on the kind of garbage eaten. Alola was once home to many Garbodor, but the population shrank precipitously after Alolan Grimer and Muk, which prey on Garbodor, were introduced to its habitat. This is said to have made the remaining Garbodor population stronger than its counterparts from other regions.
As Gigantamax Garbodor, its toxic gases become thicker and congeal into the shape of discarded toys, namely: a toy car, blocks, a toy airplane, a toy cruise ship, a Substitute doll, a Poké Doll, a Master Ball, a fish skeleton resembling Magikarp, and a toy train. Its feet seem to disappear underneath its body, which has dark blue, pink, and light green spots all over. Its eyes glow pink, and three red clouds float around the head. Its fingers no longer have visible holes in them, although they can still spray toxic gas. This toxic gas, which is also released through Gigantamax Garbodor's mouth, is capable of seeping deep into its victims' bones.
Garbodor shares similar traits to Muk and Weezing. All three Pokémon are pure Poison-type Pokémon with a single pre-evolved form, roughly the same base stat totals and evolution levels, and appear to be based on a different kind of pollution; Garbodor being land pollution.
Garbodor is based on a garbage bag that is bursting with garbage. It and Trubbish were created as a way to represent city pollution. Its visual design may be a reference to the phrase "dust bunny" (clumps of lint). As Garbodor seems to be a conscious pile of garbage, it might be based on tsukumogami, objects that have been possessed by spirits in Japanese folklore.
Gigantamax Garbodor appears to be based on a landfill. There are a few objects that can be distinguished from a variety of trash on Garbodor's body, these objects are: a Pokédoll, a Substitute doll, a toy plane similar to Latios, a toy ship, a toy car, building made from toy bricks, a skeleton of a Magikarp, a Master Ball and a toy train.
Garbodor may be a combination of garbage and odor.
Dustdas may be a combination of ダスト dasuto (dust, trash, refuse) and 出す dasu (to take out).
