Chatot is an avian Pokémon similar to a parakeet. Its head is black and resembles an eighth note, while its black tail resembles a metronome. Its plumage is brightly colored with blue wings, a yellow chest and feet, a green stomach, and a pink, hooked beak and eyelids. Additionally, there is a ruff of white feathers around its neck.
This Pokémon's tongue is similar to a human's, allowing it to imitate human speech. Chatot is also able to mimic the cries of other Pokémon and uses this ability as a defense mechanism. Chatot uses the sounds it has learned and arranges them into its own melody, and flicks its tail to keep a rhythm. Chatot are even capable of understanding the meaning of the words they mimic, the older and more experienced they become. It is diurnal, and lives along bodies of water.
In Pikachu's Island Adventure, a Chatot, Hariyama, and Exploud assisted Meowth and his cronies in claiming an island and kicking out its current residents. As a result, Pikachu and his friends agreed to help the original resident Pokémon reclaim the island.
Pearl owns a Chatot nicknamed Chatler, who often smacks Diamond's Munchlax on the head. He, like a parrot, is able to perfectly mimic human speech, which he makes a habit of, although he cannot understand what he is repeating. He first appeared in Stagestruck Starly.
In Generation IV, a person in Eterna City will trade a Chatot in return for a Buizel, and the Chatot's nickname is Charap, a mixture of its English and Japanese names. If this Pokémon was obtained in an English-language version of Diamond or Pearl and is transferred to X or Y, the game will recognize the Chatot to be Japanese.
Chatot is the only Pokémon that is not Legendary or Mythical to be banned from Generation V's Global Battle Union. This is likely due to Chatot's signature moveChatter and its ability to play pre-recorded audio, which can be abused to play vulgar words and phrases. This vulnerability is also presumably the reason for the move's ability to play pre-recorded audio being removed starting with Generation VI.
Chatot appears to be based on a parrot, specifically a masked lovebird, a species of small parrot. It also resembles a blue-and-yellow macaw, with the head crest of some cockatiel and cockatoo species. Its head looks like an eighth note, and its tail resembles a metronome what may allude to the musical nature of birds, especially parrots that are able to imitate human speech. Additionally, its white neck feathers resemble a collar.
