# Fionna Campbell

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 Max series Adventure Time: Fionna and Cake. The character is voiced by American actress Madeleine Martin.

## 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.
In August 2021, it was announced that HBO Max had greenlit a young adult animated series focusing on the characters of Fionna and Cake. When creating the Fionna and Cake series, showrunner Adam Muto stated that he wanted to focus on a character who was more normal than Finn, and wrote Fionna to be less selfless than Finn and more of an unskilled fighter.

## Appearances
### Adventure Time

Fionna first appeared in Adventure Time in the third season episode "Fionna and Cake". At the end of the episode, it is revealed that Fionna and Cake are characters within a fanfiction being written by Ice King.

### Fionna and Cake

Fionna is the protagonist of Adventure Time: Fionna and Cake, with Madeleine Martin reprising her role as the character. The series focuses on Fionna's life in an alternate version of the Adventure Time universe that does not include magic. In that universe, she is a normal person working through a series of unsatisfying jobs who yearns to go on magical adventures. Fionna experiences strange dreams of a magical world which she believes have a greater meaning.
Together with her cat Cake, Fionna emerges from the head of their creator Simon Petrikov, the former Ice King, and find themselves inside of the magical universe of Ooo. The trio then go on adventures across the multiverse in the hopes of recovering the ice crown so that Simon will have magical powers again and can restore magic to their world. In the series, it is revealed that Prismo the Wishmaster had created a real universe and concealed it inside of the Ice King's mind, which is why magic left their world when the Ice King's madness was cured and he became Simon Petrikov.

### Comics

Fionna was also the protagonist of the six-issue comics miniseries Adventure Time: Fionna and Cake which was published by Boom! Studios.

## Characteristics and personality

Fionna is a genderbent version of Finn the Human, and bears many traits in common with him as they are both tough and adventurous. She is portrayed as a teenager in the Adventure Time series, while Finn is a preteen. Like Finn, Fionna experiences complicated romantic desires, although she is not shown to suffer as greatly from lovesickness or unrequited desire as Finn, and she asserts that she does not need a romantic relationship to define herself.
In the Fionna and Cake spinoff, Fionna is portrayed as an adult in her 20s, who spends her time working menial jobs by day while dreaming of magical adventures at night.
