In Kamen Rider Ex-Aid, Ex-Aid draws his power from a series of Platformer video games starring a protagonist calls Mighty. Among other famous platformer heroes that Mighty takes after, he seems to resemble Kirby the most, as he's pink and is said to grow stronger the more he eats. One game in the series, Maximum Mighty, displays Mighty driving a mech suit with his face on it (and it gives Ex-Aid a similar set of Powered Armor), not unlike Kirby: Planet Robobot.
In episodes 99 and 100 of Kaeloo, both parts of a Multi-Part Episode, Kaeloo and her friends wear costumes of well-known video game characters. Mr. Cat's costume is a fusion between Pikachu from Pokémon and Kirby.
