Finn is a 14-year-old human boy who loves nothing more than going on adventures and saving the day. He wears a hat that covers his extremely long flowing golden hair. He is prone to exclamations and outbursts including “Mathematical!” and “Algebraic!”. When Finn was a baby, he did a ‘boom boom’ leading to his adoption by Jake’s parents, Joshua and Margaret, which was detailed in “Memories of Boom Boom Mountain”. Considering himself a hero, Finn has a lust for adventure and swore long ago that he would help anyone in need, but being so full of energy, he has trouble in situations that require him to do tasks other than fighting. His fears include the ocean, clowns, spiders, and being judged by older people due to his age. After initially having a unrequited crush on Princess Bubblegum, Finn is in a relationship with Flame Princess.
