- Yo-kai Watch Shadowside: Minor Yo-kai
- Yo-kai Watch Wibble Wobble: Playable Yo-kai (Lightside form only)
In his Lightside form, Ikarin is a white and yellow squid with black markings, and his eyes are red with no irises.
His Shadowside form looks much like Ikarin, but with a much bigger body and more tentacles. His teeth are arranged in a circle in his mouth, which are very sharp.
He's voiced by Kazuhiro Fusegawa.
