===Generations II to IV===
ExtremeSpeed inflicts damage
and is an increased [[priority]] move. If the target does not use an increased priority move during the round that it is used , ExtremeSpeed will go first regardless of the user's or target's speed. If the target also uses a move with an increased priority of +1 during the same round that the user uses ExtremeSpeed, the attack order of the users will be determined normally.
