Source-derived summary

Fionna Campbell, also called Fionna the Human, is a fictional character from the Adventure Time franchise. She was first introduced in the Adventure Time episode "Fionna and Cake" as a genderbent version of the show's lead character Finn the Human. She is the protagonist of the HBO Max series Adventure Time: Fionna and Cake.

Creation and development

Fionna Campbell and Cake the Cat were created by Adventure Time storyboard artist Natasha Allegri as fan art. Fionna Campbell was originally created as a genderbent version of Finn the Human, the protagonist of the series Adventure Time, while Cake was a genderbent and species swapped version of Finn's brother Jake the Dog. In an interview with Comic Book Resources, Allegri stated that she first designed the characters after someone on an online forum requested that she draw genderbent fan art.

Allegri shared her drawings of the characters on Tumblr, where they become popular with fans, later sending them to Frederator Studios, one of the production companies behind Adventure Time. As a result of fan feedback, the characters appeared in the third season Adventure Time episode "Fionna and Cake". Fionna is voiced by American actress Madeleine Martin. The character subsequently appeared in other episodes of the series.
