The user attacks with a swift chop. It can also break barriers, such as Light Screen and Reflect.
Brick Break can target any Pokémon adjacent to the user. Brick Break does damage to the target. If a Pokémon uses barriers such as Reflect or Light Screen, Brick Break will first shatter them, removing its effects, then will attack and damage the target. However, following Generation V, the move won't break the barriers if the Pokémon is a ghost type.
