Finn Campbell Mertens, commonly called Finn or Finn the Human, is the central hero of the animated series Adventure Time. Introduced in a short pilot and then developed into a long-running television character, Finn combines childlike enthusiasm with an increasingly reflective, moral outlook as the show progresses. He is chiefly recognized by his white hat with ear-like points, blue clothing and green backpack, and by the many swords and artifacts he collects during his adventures.
Character overview and traits
Finn is portrayed as a courageous, adventurous human youth who spends much of his time exploring the post-apocalyptic Land of Ooo. He is energetic, idealistic, and determined to help others, but the series also follows his imperfections: he makes mistakes, faces loss, and wrestles with questions of identity and responsibility. His closest companion is Jake the Dog, a magical dog with stretching powers who serves as friend, adoptive brother and mentor. Finn is frequently depicted as a skilled swordsman and self-styled hero, undertaking quests that range from rescuing friends to confronting cosmic mysteries.
Creation and voice performance
The character was created by Pendleton Ward, who developed Finn for an initial short that later evolved into the full television series; the early pilot featured a version of the character named Pen. For the main series, Finn is voiced by Jeremy Shada, whose performance shaped much of the character’s youthful tone and emotional range. The pilot’s version was voiced by Zack Shada, Jeremy’s older brother, reflecting the character’s refinement between the short and the series proper.

Romantic storylines and friendships—most notably with princesses and other inhabitants of Ooo—play a role in his emotional maturation.
