Generation I
Quick Attack does damage, and is an increased priority move. If the opponent does not use an
increased priority move during the round that it is used, Quick Attack will go first regardless
of the user's or opponent's speed. If the opponent also uses an increased priority move during
the same round that the user uses Quick Attack, the attack order of the users will be
determined normally. If the user is put to sleep or frozen during the round that Quick Attack
is (or attempts to be) used, Quick Attack's increased speed priority will not be reset.
Subsequently, it will only be reset on the turn after the user wakes up or is defrosted, or if
the user switches out.
