Origin
Extreme Speed (formatted as "ExtremeSpeed" prior to Generation VI) is a damage-dealing Normal-type move introduced in Generation II, being the signature move of Arcanine prior to Generation III. Due to its increased priority, it allows the user to move before its target if they use a move that does not have increased priority. Lucario learns this move by leveling up to level 51 in Generation IV, and 65 in Generation V and onward.
