Finn is a playable Exosuit of the Banzai Squadron on Project Exonaut from Adventure Time. His Weapon Mod, similar to Ultimate Humungousaur, increases the Tridex's Shots to five instead of three. Finn is available for purchase at level 10 for 750 credits. Also,he is unlocked for the holiday event. The Finn suit is a suit that is built stronger than most Banzai suits. It also provides a good balance of agility as well for moving around large fields. The Finn suit is a great Exosuit choice for players learning and understanding the gameplay style.
In The ShowEdit
Finn is the last human in the "Land of Ooo", supposedly the future of earth after the Mushroom Wars, probably reffering to the mushroom cloud made by nuclear bombs. He is an "Adventurer", actively fighting the Ice King (before the war known as Simon), along with various other "monsters" that are appearently results of the nuclear radiation, similar to the Chernobyl wolves. He lives in the Tree Fort (In Project Exonaut Finn's Treehouse), along with Jake and Beemo and is friends with Marceline, Princess Bubblegum and Lumpy Space Princess.
In the show, Finn wears blue shorts and a T-shirt, with a white hat and a green backpack. He sometimes carries either a golden sword, an iron sword, a sword with tree roots for a handle, or a demon sword hidden in a dungeon by his "father" Joshua. In Project: Exonaut, he wears white pants (really more like armor), a sword strapped on his back, along with an axe, a mace, and various spikes on his clothes. The reason for this is most likely an attempt to make him seem less like a cartoon, a process similarly used on both Benjamin Tennyson and Grim.
