Pokédex entries
What each game says about it, in the games' own words.
| Red / Blue | Appears in filthy areas. Thrives by sucking up polluted sludge that is pumped out of factories. |
| Yellow | Made of hardened sludge. It smells too putrid to touch. Even weeds won't grow in its path. |
| Gold | As it moves, it loses bits of its body from which new GRIMER emerge. This worsens the stench around it. |
| Silver / SoulSilver | Wherever GRIMER has passed, so many germs are left behind that no plants will ever grow again. |
| Crystal | When two of these POKéMON's bodies are combined together, new poisons are created. |
| Ruby | GRIMER’s sludgy and rubbery body can be forced through any opening, however small it may be. This POKéMON enters sewer pipes to drink filthy wastewater. |
| Sapphire | GRIMER emerged from the sludge that settled on a polluted seabed. This POKéMON loves anything filthy. It constantly leaks a horribly germ- infested fluid from all over its body. |
| Emerald | Born from polluted sludge in the sea, GRIMER’s favorite food is anything filthy. They feed on wastewater pumped out from factories. |
| FireRed | Sludge exposed to X rays from the moon transformed into GRIMER. It loves feeding on filthy things. |
| LeafGreen / Y | Appears in filthy areas. It thrives by sucking up polluted sludge that is pumped out of factories. |
| Diamond / Pearl / Platinum / Black / White | It was born when sludge in a dirty stream was exposed to the moon’s X-rays. It appears among filth. |
| HeartGold | As it moves, it loses bits of its body, from which new GRIMER emerge. This worsens the stench around it. |
| Black 2 / White 2 | Born from sludge, these Pokémon now gather in polluted places and increase the bacteria in their bodies. |
| X | Sludge exposed to X-rays from the moon transformed into Grimer. It loves feeding on filthy things. |
| Omega Ruby | Grimer’s sludgy and rubbery body can be forced through any opening, however small it may be. This Pokémon enters sewer pipes to drink filthy wastewater. |
| Alpha Sapphire | Grimer emerged from the sludge that settled on a polluted seabed. This Pokémon loves anything filthy. It constantly leaks a horribly germ-infested fluid from all over its body. |
| Sun | Its main source of food is the slimy industrial waste of factories. This Pokémon’s numbers have been decreasing in recent years. |
| Moon | It was born from sludge transformed by exposure to X-rays from the moon. When its internal load of germs decreases, it dies. |
| Ultra Sun | It was born from sludge on the ocean floor. In a sterile environment, the germs within its body can’t multiply, and it dies. |
| Ultra Moon | The wastewater coming from factories is clean these days, so Grimer have nothing to eat. They’re said to be on the verge of extinction. |

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
