Roost (move)

Roost (Japanese: はねやすめ Feather Rest) is a non-damaging move introduced in Generation IV. It was TM51 in Generation IV. It regained its TM status in Gen VI, albeit as TM19. In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, it is TM55.

Generation IV
Roost restores half of the user's maximum.

If a Pokémon successfully uses Roost, until the end of the turn, its Flying type is ignored when it is hit by attacks: If the Pokémon has another type, only that type is considered; if the Pokémon is a pure Flying type, all attacks will be normally effective against it.

Generation V onward
If a Flying-type Pokémon successfully uses Roost, it will now lose its Flying type until the end of the turn: If a Pokémon is ungrounded only due to its Flying type, successfully using Roost will make it grounded until the end of the turn (and therefore susceptible to effects such as terrain and ).
 * If a pure Flying-type Pokémon successfully uses Roost, it will become until the end of the turn. If a Pokémon is a Fire/Flying type that lost its Fire type due to, using Roost causes it to become typeless until the end of the turn.
 * If a Pokémon with another type besides Flying uses Roost, it will lose its Flying type until the end of the turn (but will not have it replaced with the Normal type).
 * If a pure Flying-type Pokémon that has been affected by / successfully uses Roost, its Flying type will be replaced by Normal, in addition to retaining its Grass or Ghost type addition.

If powered up by a Flyinium Z into Z-Roost, all of the user's lowered stats are reset.
