From Bulbapedia, the community-driven Pokémon encyclopedia.
Pursuit (Japanese: おいうち Pursuing Attack) is a damage-dealing Dark-type move introduced in Generation II. This move has the highest possible priority value of all moves in Pokémon games.
If the target Pokémon is switched out on the turn Pursuit is used, Pursuit's power becomes 80 and will deal damage before the Pokémon is switched out. This does not apply if used on an ally switching out, used on a fleeing Pokémon, or when used on a Pokémon using Teleport, Baton Pass, U-turn, or Volt Switch or being forced to switch out.
In the Japanese version of Pokémon Diamond and Pearl, when a Pokémon using a choice item uses Pursuit and the target Pokémon switches out, the Pokémon holding the item is allowed to change its move on the next turn. This glitch was fixed in localized versions and Platinum.
In Pokémon Platinum, and HeartGold and SoulSilver, this move can trigger the acid rain glitch by knocking out a target that was about to switch while Trick Room, Gravity, Uproar or a weather condition other than rain is active.
