Imposter (Japanese: かわりもの Changer) is an Ability introduced in Generation V. It is the signature Ability of Ditto. This Ability is exclusively obtained as a Hidden Ability.


In battle

You can discuss this on the talk page.

As soon as the user comes into battle, it transforms into its opponent. Imposter copies the target's appearance, cry, moves (which all have 5 PP), Ability, stats (except HP), stat changes (but not stat multipliers such as with Choice Specs), weight, and Mega Evolution or form (regardless of held item). Imposter does not copy its opponent's IVs (for the purpose of Hidden Power), friendship or gender.

Imposter will not activate if the opponent is transformed, disguised with Illusion, or behind a substitute. Imposter only activates when the Pokémon with the Ability is sent out; if it fails to transform into an opponent, it will not activate unless the Pokémon with Imposter is withdrawn and sent out again.

In Double and Triple Battles, Imposter will copy the opponent in the position directly opposite it. If there is no opponent directly opposite to it, it will not transform.

A transformed Pokémon can use Z-Moves exclusive to a species it has transformed into, if it holds an appropriate Z-Crystal. If the Pokémon with this Ability has transformed into a Mega-Evolved Pokémon, it cannot use any Z-Moves, even if it holds an appropriate Z-Crystal.

Role Play fails if the target has the Ability Imposter. Entrainment fails if the user has the Ability Imposter. Imposter cannot be copied by Trace, Power of Alchemy, or Receiver.

Even if a Pokémon transforms into Meteor Form Minior, Shields Down will not prevent a transformed Pokémon from being afflicted with status conditions.

If the Pokémon with this Ability transforms into a Pokémon that has no type (i.e. it was a pure Fire type that used Burn Up), the transformed Pokémon will become Normal-type; if such a Pokémon has additionally been affected by Forest's Curse or Trick-or-Treat, the user will become Normal-type with an added Grass or Ghost type respectively. If the Pokémon with this Ability transforms into a dual-typed Pokémon that has used Burn Up, however, Imposter will copy the user's current types (and type additions) as usual.

Outside of battle

Imposter has no effect outside of battle.
