Grimer sits at the start of its evolution line — not yet at full power, but that changes fast. Most trainers push through to Muk as fast as possible. Only weak to Ground and Psychic. Known as the Sludge Pokemon.
HP and Attack carry most of Grimer's stat budget. Speed's the obvious dump stat. Common in the wild and yields 1 HP EV. Follows a medium-fast 1M XP curve.
There are a hundred or so of them living in Alola’s waste-disposal site. They’re all hard workers who eat a lot of trash.
Brought to Alola to solve the garbage problem, Grimer seems to relish any and all kinds of trash.
Grimer Weakness
GoodGrimer is weak to Ground and Psychic-type moves. 5 resistances help offset the weaknesses. Just 2 weak spots to worry about, which keeps teambuilding straightforward.
One evolution ahead. Grimer grows into Muk through a straightforward two-stage chain. No compatible partners for breeding via one egg group. Eggs are average hatch time. Evolving adds up to 175 stat points total.
How to Evolve
Breed Grimer easily from the Indeterminate egg group. Pass egg moves like Acid Spray, Curse, Haze and 10 more to offspring.

Stench is the go-to ability for Grimer. It has a 10% chance of making target Pokémon flinch with each hit. Its hidden ability Poison Touch can work in specific setups. Sticky Hold is the other option — pick based on what your team needs.
Base 25 Speed is low. Priority moves or Trick Room are the way to go. On offense, Grimer is leaning toward the physical side (base 80 Attack). Best used as a trick room.
