Grimer (Alola) in Emerald Imperium

Poison / Dark — where to catch it, what it learns, and how it differs from the official games.

Compared with the official games

Against the base species it is built from:

Type Poison → Poison / Dark
Abilities gains Gluttony, Power Of Alchemy and loses Stench, Sticky Hold

Compared against present-day official data. The Fairy type and hidden abilities arrived after Pokémon Emerald, so a difference here can belong to the series rather than to this hack.
