Finn the Human also known as Finn or Finn Mertens is one of the two main protagonists of the Cartoon Network series Adventure Time created by Pendleton Ward. He is seen chained up in Mom's floating castle with his dog/friend Jake.
Finn is a teenaged human boy with bad teeth. Finn typically wears a munsell blue, t-shirt, denim shorts, a two-colored lime green circular backpack, rolled-down white socks, and a pair of black shoes. Finn's most prominent attire is a white hat with two "ears" sticking out on top that covers his entire head minus his face. Despite his age and appearance, Finn seems to be quite strong and athletic.
Finn is also almost incapable of doing anything evil or unjust, and will struggle greatly against doing such things. Although at times impulsive and aggressive, Finn is a kind, brave, selfless, and righteous boy. His aspirations to become a great hero makes him somewhat of a moral sheriff, as he is willing to help and protect any innocent person or creature. Finn has a very strong sense of responsibility and becomes upset when he is unable to help others. While he portrays himself as a rough and tough hero, Finn has a tender side that is capable of love and compassion.
