Mimikin first appears in EP044, when he posseses Katie into rudely mimicking the homeroom teacher. Nate identifies Mimikin, who causes Katie to mimic Nate and Whisper horribly before running off to the rooftop. Nate summons Jibanyan, but Mimikin mimics his obsession with Next HarMEOWny, causing Jibanyan to run off crying. Nate then summons Robonyan, who Mimikin gives an atrocious impression of. Robonyan derides Mimikin's attempt as poor and scans Mimikin's DNA, transforming into an exact copy of Mimikin. Robonyan then does an impression of Mimikin, calling himself the "least entertaining Yo-kai", humiliating Mimikin into submission. Just as Robonyan attempts to leave, Mimikin grabs him and pleads with Robonyan to teach him how to make perfect impressions. Robonyan accepts, and Mimikin apologizes to Nate, giving him his Yo-Kai Medal. He is seen later training with Robonyan by mimicking him.
Mimikin reappears in EP068, when it is revealed he is the one who, using his new ability to transform into Nate, impersonated him and visited Katie, Bear, and Eddie, and give them a strange impression of Nate. As Nate confronts Mimikin, Robonyan appears and explains to the boy his double is taking a test to prove his mimicking skills, announcing that Mimikin would take Nate's place for a day and should he doesn't create suspicions, he would pass. Mimikin then tries to pass as Nate, but his performance is exaggerated. Despite this he pass and the next day, with newfound confidence, uses Nate's appearance to make his classmates laugh, much to the real Nate's dismay.
