Mimikyu is a small Pokémon whose body is almost entirely hidden under an old rag. Its small size makes it one of, if not the shortestGhost-type. Its beady black eyes are visible through holes in the body of its disguise, and the fringe of an amorphous foot or lower body is visible under the hem. Occasionally, it will also extend a black appendage from under its rag. The veil itself resembles a Pikachu. The cloth is yellow with black-tipped ears. The Pikachu face appears to be drawn with crayons, consisting of black eyes, red cheeks, and a squiggly black mouth. The head is hollow and can be used to store objects. Mimikyu also carries a small stick resembling a lightning bolt to create a tail for its costume. When its disguise is damaged, the costume's head droops limply backward, revealing Mimikyu's ruse. Larger rips in the costume are accompanied by shadowy vapors pouring out from whatever is hidden within.
A lonely Pokémon, Mimikyu is always covered by its disguise. It is unknown what Mimikyu's true appearance looks like. Since this Pokémon is weakened by sunlight, it is rumored that the veil is used for protection. It is believed that seeing its true form will cause a mysterious illness or even a painful death. Because of this, Mimikyu will become agitated and violently stop anyone from attempting to look underneath its rag. Mimikyu's disguise is modeled after Pikachu because of the popularity of Pikachu-styled merchandise, thinking that its disguise would allow it to make friends with people. Unfortunately, this attempt makes its disguise look more creepy. The rag it wears allows Mimikyu to avoid attacks. If its rag is damaged or its neck is broken, it will spend all night patching it in front of a mirror as if its life depends on it. Repairing the rag correctly is often difficult for Mimikyu, so it cries a lot on the inside. It then seeks revenge on the one that damaged it, fearing that its true identity could have been exposed. Unforgiving, Mimikyu will take down the culprit to the point of costing its life in the process.
Mimikyu, the Disguise Pokemon. A Ghost and Fairy type. It wears a ragged head cover to look like a Pikachu, but little is known about this Pokémon. It's said that a scholar who once tried to look inside met his end.
A Mimikyu briefly appeared in GOTCHA!, under the ownership of Acerola.
Mimikyu appears as a Pokémon summoned from the Poké Ball, where it uses its signatureZ-MoveLet's Snuggle Forever on any opponent who gets too close to it. Unlike its depiction in the core seriesgames, Mimikyu grabs its target instead of jumping on top of it. If the target is at 90% damage or more, they will be instantly KO'd, and Mimikyu will leave behind its disguise and presumably depart afterwards.
Mimikyu also appears as a Spirit. If its Spirit is equipped, the fighter will start the match with Death's Scythe.
This Pokémon was unavailable prior to Generation VII.
According to an official piece of merchandise, Mimikyu's height does not count the head of the disguise, only the body.
In the Pokémon of the Year poll held by The Pokémon Company in 2020, Mimikyu was voted the most popular Generation VII Pokémon, receiving 99,077 votes. It was also the third-most popular Pokémon overall.
Due to a glitch, if Mimikyu is hit by Rollout or Ice Ball, the damage multiplier for these moves can also be applied to other moves. Mimikyu shares this trait with Eiscue. It was patched out in Version 1.3.1 of Pokémon Sword and Shield.
Mimikyu's disguise is based on Pikachu. The execution of the disguise is similar to ghost costumes made from bedsheets. Mimikyu also shares similarities with the Bugul Noz, a Breton myth about a kind and gentle fairy spirit whose horrifying ugliness causes it to be perpetually alone. The fact that Mimikyu's appearance can kill is a reference to Lovecraftian or eldritch monsters; if any person were to see their true forms, they would either be driven insane or die.
Mimikyu and Mimikkyu may be derived from mimic and きゅうきゅう kyūkyū (onomatopoeia for squeaking, similar to Pikachu). It may also involve a corruption of 迷宮 meikyuu (mystery).
