Appearance

(previously spelledand also known as) is an in-universe fictional character and the gender-swapped version of Finn who was created by the Ice King in his fan-fiction from a strange red glowing inspiration during Ice King's sleep. In the real world, she was created by series character designer Natasha Allegri in a series of web comics and drawings. She and the other gender-swapped characters appeared occasionally in their own segment of the show. She is usually seen in the company of Cake , her own stretchy companion and also adoptive sister. Fionna's nemesis is the Ice Queen . She used to have a crush on Prince Gumball and shows signs of attraction towards Marshall Lee , but she's also shown to have a past with Flame Prince . Ice King fantasizes about one day making her real and marrying her.

While usually appearing as black dots, her eyes are seen as blue when enlarged. She wears a rabbit-themed hat (similar to Finn's bear-themed hat) with exposed locks of blonde hair and also has teeth missing in a similar fashion to Finn. Unlike Finn, her neck and blonde hair are shown. She also has buck teeth in several episodes, fitting with her rabbit hat. When she is not wearing her hat, her hair goes down to between her knees and ankles. Her outfit includes a teal blue shirt with elbow-length sleeves, a dark blue skirt, and over-the-knee socks with two thin, light blue horizontal stripes at the top. Fionna is a heavier set than Finn (which Natasha referred to as "chubby cute"). She has a green backpack (similar to Finn's) and black Mary Jane shoes.

Personality and character traits

Although Fionna is known to mostly keep her calm, she can be provoked to anger. She will often try to act like one of the guys, so she fits in easily with friends like Marshall Lee or Prince Gumball.

Fionna is a fearless, thrill-seeking, adventure-loving hero who will rescue any prince from the Ice Queen or do any task to better herself or help citizens. She, much like Finn, is also very hard-headed as shown when Cake wanted her to date Prince Gumball and she was stubborn about it.

During the events of "The Prince Who Wanted Everything," Fionna shows a rather ignorant personality towards Lumpy Space Prince. However, this trait may only exist in Lumpy Space Princess's stories, as LSP herself has a very similar personality.

So far, none of Fionna's fears have been introduced and she is known to be very courageous and brave.

Relationships

Cake

As housemates, adopted sisters, and best friends; Fionna and Cake share a very deep and strong bond. Having been raised together by Cake's parents, the duo share a relationship similar to that of siblings, with Cake watching over Fionna and giving her advice constantly as her older sister. Though they have an unconditional love for each other, Fionna can get frustrated with Cake because of her pushiness, shown especially in "Fionna and Cake." Though she sometimes leads Fionna down the wrong path, Cake genuinely means well for her companion and is usually an encouraging and protecting figure. It is shown in the Card Wars comics that the two would go to great lengths for each other, despite the fact that Cake initially ignored Fionna (to train for the Card Wars tournament- similarly to her counterpart, Jake.) to study for the competition.

Lord Monochromicorn

Prince Gumball

As the trusted steed of her crush Prince Gumball and the boyfriend of her best friend Cake, Fionna and Lord Monochromicorn are on good terms and are well acquainted with each other.

Prince Gumball was Fionna's crush. Fionna gets flustered if Prince Gumball compliments Fionna on being "beautiful." She acts in such a way as when Finn was in love with Princess Bubblegum. Although throughout the Fionna and Cake episodes, she no longer has feelings for him, but only sees him as a friend.

However, in the Card Wars comic series, it appears that Fionna still has feelings for Prince Gumball as she blushes several times. This continues until it is revealed that he is the Floop Master: and is on the verge of defeating Cake on a match of Card Wars. Fionna is surprised that he is the Floop Master, and Gumball tells her that the reason he never revealed his identity was because he didn't want to make her choose between Cake and himself. Fionna, however, says that that wasn't even a question and proceeds to help Cake win.

Marshall Lee

Fionna and Marshall Lee are good friends. In "Fionna and Cake," Marshall gives Fionna the sign of horns at Prince Gumball's ball. In "Bad Little Boy," he fakes a fatal wound and tells her that he might die, so she should just admit that she's in love with him. Fionna responds, crying and angry that he would ask something like that at a moment like that, to which he reveals he is faking and is punched by Fionna.

Lumpy Space Prince

Fionna has a good relationship with Lumpy Space Prince. He doesn't interact directly with her until "The Prince Who Wanted Everything", but appeared in the two previous Fionna and Cake episodes, 1 with only a single line and the other with no lines at all. In the episode, Fionna helped him adjust to a normal life after running away from home, and assisted him in defeating his monstrous parents. While dancing, Fionna becomes entranced by his "handsome spell" and called him "pretty", which Lumpy Space Prince reacts by pushing her away, stating that they would never marry. Later, when the prince's monster parents arrived, Lumpy Space Prince apprised her that it was then his end, and asked if she made her proud, to which Fionna replies that she did not care. It was unknown if this means that Fionna actually does not care about the prince at all, but after his parents' defeat, Fionna becomes enticed by his "hotness" again and served him dinner with Cake.

Flame Prince

Although Fionna seems to have some attraction toward Flame Prince in the Fionna and Cake comics, in "Five Short Tables", Fionna expresses either fear or nervousness when she sees him in the library. It can be assumed she was once in a relationship with him, but it ended up in a bad breakup, similar to Finn and Flame Princess's relationship, and that unlike their genderswapped counterparts, they are not on good terms.
