From Bulbapedia, the community-driven Pokémon encyclopedia.
Trick-or-Treat (Japanese: ハロウィン Halloween) is a non-damaging Ghost-type move introduced in Generation VI. It is the signature move of Pumpkaboo and Gourgeist.
Trick-or-Treat adds the Ghost type to the target, in addition to the Pokémon's original type(s). If it is used against a dual-type Pokémon, that Pokémon will have three types at once. If the target already has an additional type added to it by Forest's Curse, that type is replaced with the Ghost type.
Trick-or-Treat will fail if the target Pokémon is already Ghost-type.

- Using Trick-or-Treat on a Psychic-type Pokémon is currently the only way to deal 4x super-effective damage with Ghost- or Dark-type attacks outside of Inverse Battles.
- Additionally, using Trick-or-Treat on a Normal-type Pokémon is currently the only way for a Pokémon to have a sole weakness to the Dark type.
