Illusion

Takes the appearance of the last conscious party Pokémon upon being sent out until hit by a damaging move.

How it works

This Pokémon, upon being sent out, appears to have the species, nickname, and Poké Ball of the last Pokémon in the party that is able to battle. This illusion breaks upon being hit by a damaging move.

Other damage, e.g. from weather or Spikes, does not break the illusion, nor does damage done to a Substitute.

If the party order becomes temporarily shuffled around as Pokémon are switched out in battle, this ability chooses the last Pokémon according to that shuffled order.

Effects can vary between games. This is the synced main-series reference; check the rules of the game you are playing.
