Copycat

Copycat is not a Pokémon but rather a Trainer card in the Pokémon Trading Card Game, representing a character from the Pokémon universe known for her ability to mimic others. While not a creature with a Pokédex entry, the character Copycat, whose Japanese name is Imposter, first appeared in the Generation I games, Pokémon Red and Blue, residing in Saffron City. She is famous for her collection of dolls and for her unique habit of dressing up and imitating other people, including the player character. Her role in the games often involves a mini-game or quest where the player must retrieve an item for her, after which she might reward them with a TM or other useful item. In the anime, Copycat has appeared in episodes, showcasing her distinctive personality and mimicry talents, further cementing her as a memorable non-player character. Her ability to "copy" is a recurring theme, translated into various card effects throughout the TCG's history, often involving hand manipulation based on the opponent's hand. She embodies a playful and somewhat mischievous aspect of the Pokémon world, highlighting the diverse cast of characters that populate its cities and towns, beyond just trainers and Pokémon.
