When used by a Ghost-type, the user sacrifices half of its max HP to sap the target by 1/4 of its max HP per turn. When used by anything else, the user's Speed is decreased by 1 stage and its Attack and Defense are increased by 1 stage.
The user takes one-fourth of its maximum HP to create a substitute; this move fails if the user does not have enough HP for this. Until the substitute is broken, it receives damage from all attacks made by other Pokemon and shields the user from status effects and stat modifiers caused by other Pokemon. The user is still affected by Tickle, Hail, Sandstorm and Attract from behind its Substitute. If a Substitute breaks from a hit during a multistrike move such as Fury Attack, the user takes damage from the remaining strikes.

If the target switches out on the current turn, this move strikes with doubled power before the switch. Baton Passers still escape safely. When a faster Pokemon uses Pursuit against a U-Turner, the U-Turner is hit for normal damage; when a slower Pokemon uses Pursuit against a U-Turner, the U-Turner makes its attack, then is hit by Pursuit for double power, and switches out.

Almost always goes last; in trainer battles, the target is switched out for a random member of its team. Escapes from wild battles. Has no effect if the target has Suction Cups or used Ingrain.
