Fionna (previously spelled Fiona, and also known as Fionna the Human) is a fictional character and the gender-swapped version of Finn and created by the Ice King in his fan fiction. 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 in the season three episode "Fionna and Cake." She is usually seen in the company of Cake, her own stretchy companion also adoptive sister. Fionna's nemesis is the Ice Queen. Fionna is a main character in The Lich's Revenge.She was in one of Finns visions along with Cake.When Finn and Jake found the two girls Fionna was unconscious, but then woke up. Fionna got help Marshall Lee and Ice Queen. She helped in defeating The Witch.
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. Unlike Finn, her neck and blonde hair are shown. Her outfit includes a teal blue shirt with elbow-length sleeves, a dark blue skort, and high-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 Mary Jane shoes.
Much like Finn, Fionna is an adventurous fun girl who is always up for an adventure. She is energetic and will never back down from a fight. She is a fun and fearless young girl who lives without limits. She is also very tough and doesn't cry unless it's about something major like death or heartbreaks.
