Grimer is a purple pile of poisonous sludge with two arms that have hands with three fingers. It has saucer-like eyes and a gray mouth. Grimer may be distantly related to Koffing, another Pokémon that is associated with pollution. It's height is 2'11" and weight is 66.1 lbs.
Grimer emits a very pungent, noisome odor due to the billions of malodorous bacteria contained within its sludge. Since Grimer's body lacks a solid form, it can slip through the smallest of openings. Grimer's germ-infested entrails can also cause the ground that it passes over to be unable to bear any plant life.
As far as Grimer's skills in battle are concerned, Grimer mainly attacks by flinging poisonous sludge (or mud) at its foes. Grimer can also wield fire, electricity, and various Ghost attacks. Grimer is part of one of the four Pokémon evolutionary lines that can use Gunk Shot.
It is rumored that as it moves, it loses bits of its body from which new Grimer emerge. This is said to worsen the stench around it. Grimer are sensitive about their smell, say a wrong turn about them and will attack without warining

Grimer tend to feed on sludge, sewage, and other filthy things.
Sonic, Ash and friends first encountered Grimer in Sparks Fly for Magnemite. A Muk and a large group of angry Grimer were gumming up the turbines in the power plant in Gringey City causing a city-wide power loss.
