Jo is a regular female human with a hat that has long bunny ears and a cape over her neck dropping down to her legs. The cape and hat have both the same shade of white. She also wears a light blue t-shirt that is torn above her belly button and blue shorts. Her hair is brown in color. Her skin has a low tanned tone, and seems to be barefoot.
Jo was always hyper, playful, and although easily frightened of her, gained trust for Marceline later on. She seemed to have a liking in music as she asks Two Bread Tom to play a song on his guitar and Marceline to continue the song on her ax bass.
In the "Islands" graphic novel, she was shown to be resourceful enough to survive in the wild for an extended period of time. She also demonstrates strong leadership by opposing Two Bread Tom and splitting from the main group.
Islands graphic novel
|The following information is from the Adventure Time comic book series. It may not be part of the same canon or continuity as the animated series.|
The tribe eventually arrived at Founders' Island and established a colony. The other kids made fun of Jo for still wearing her protective animal hat, but Two Bread Tom always looked out for her. One day, Jo, Two Bread Tom, and a human named Michiko embarked on an expedition to explore more of the island. Jo was abducted by a giant bird and carried far from the others, and spent weeks surviving in the wild and making her way home.
When she eventually made it back to the colony, she found that attitudes towards safety had changed. Everyone was wearing their animal hats again, and Two Bread Tom was overseeing the construction of an early version of the Guardian. Jo disagreed with his plans to seal off the islands, so she and a group of others split from the main group. This is probably the origin of the hiders.
- In pre-production, she was a boy, and her name was Graham.
