Powder is a non offensive Bug-type move.
This move is an increased priority move that bypasses accuracy checks to always hit, unless the opponent is in the semi-invulnerable turn of a move such as Dig or Fly. If a Pokémon affected by Powder attempts to use a Fire-type move during that turn, they take damage equal to 25% of their maximum HP and cannot execute the move (PP is still consumed).
Powder does not prevent a Pokémon from thawing itself by using a move like Flame Wheel. If a Pokémon affected by Powder attempts to use Natural Gift while holding a Berry that makes the move Fire-type, the Pokémon takes damage from Powder but the Berry is not consumed.
Grass-type Pokémon are immune to Powder.
