Biology

Physiology

Grimer is a purple pile of poisonous sludge. It has saucer-like eyes and a gray mouth. Grimer may be distantly related Koffing, another Pokémon that's themed with pollution.

Gender differences

None.

Special abilities

Grimer emits a very pungent, noisome odor. Since Grimer's body lacks a solid form, it can slip through the smallest of openings. Grimer's germ-infested entrails 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-type attacks. Grimer is part of one of the four Pokémon evolutionary lines that can use Gunk Shot.

Behavior

Habitat

Grimer thrive anywhere there is pollution.

Diet

Main article: Pokémon food

It eats sludge, sewer water, and other filthy things.

In the anime

When Celadon City Gym Leader Erika was a youngster, she got lost one day and ran into a Grimer. However, a Gloom chased the Grimer off and saved her.

Ash and co. first encountered this filth-ridding Pokémon in Sparks Fly for Magnemite. They were gumming up the turbines in the powerplant in Gringy City. Grimer and Muk chased Ash, Misty and Brock after a negative comment on how they smelled was made. Magnemite and Magneton chased them off, leaving Ash to capture the Muk making another strong battler.

In the manga

Koga wears a Grimer on his shoulder in the form of a ninja outfit in Pokémon Special. He used it extensively to smother Green, preventing him from breathing.

His daughter, Janine, is later seen with a Grimer. She uses it against Falkner during the Gym Leader faceoff, using its Minimize attack to outwit his Noctowl.

In the TCG
