Cake the Cat is Jake the Dog's gender-swapped cat counterpart from Ice King's fan-fictions who debuted in the ninth episode of Adventure Time's Season 3, titled "Fionna & Cake".

Cake is one of the few Variants that is a whole other character rather than just a different outfit or variation for its respective Fighter. The other Variants that share this trait are Fern, Uncle Shagworthy, Black Lantern, Prime, and Nubia.
