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 also finishes 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 Garbodor devour garbage in order to grow larger. Alola was once home to many Garbodor, but the population shrank precipitously after Grimer was introduced to its habitat. This is said to have made the remaining Garbodor population stronger than its counterparts from other regions. Alolan Muk prey on Garbodor.
As Gigantamax Garbodor, its size has increased with an altered look. The sclera in its eyes are dark pink. The feet disappear, with the lumpy body expanding. Several discarded toys appear on Garbodor. The toys are as follows: toy car, blocks, toy airplane, toy cruise ship, Substitute doll, Poké Doll, Master Ball, fish skeleton resembling Magikarp, and toy train. Its fingers no longer have holes in them. The spikes on its shoulder become longer; the right arm becomes bulkier; it has dark blue, pink, and light green spots all across its body; and three red clouds float around the head.
When Gigantamaxing, its toxic gas becomes thicker. This results in the gas taking a solid shape of discarded toys. Gigantamax Garbodor releases the gas through its mouth and fingers and should the gas engulf someone, the toxin will seep deep into their 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. 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.
Garbodor may be a combination of garbage and odor.
Dustdas may be a combination of ダスト dust (trash, refuse) and 出す dasu (to take out).
