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, on a fleeing Pokémon, on a Pokémon using Teleport or Baton Pass, or on a Pokémon being forced to switch out.
In the case of the target Pokémon using U-turn or Volt Switch, if Pursuit hits the target before it uses its move, Pursuit will have 40 base power; otherwise it will be 80.
