| The following article is about something that appeared after the Birthday Bash update in FusionFall, and so will not appear in FusionFall Retro.|
As such, it solely exists for archiving part of the original game.
–Finn the Human
Finn the Human is a teenage boy who fights evil and travels the Land of Ooo with his brother and best friend, Jake. Finn used to have a crush on Princess Bubblegum, one of the many princesses of the land. However, Finn recently took a liking to Flame Princess, despite their rocky start .
War Against Fuse
In the future, Finn had escaped The Land of Ooo due to an invasion of the Ice Kingdom and the Candy Kingdom. Finn is not seen in The Future. He has presumably fallen in battle, leaving Jake as the only character from the show who had survived.
Finn is in Orchid Bay in front of the flower pad to the Ice King's Fortress next to Johnny Bravo. He is there to get heroes started on several quest arcs, beginning with the Magical Toadstool in Peach Creek.
Adventurous ArrivalFinn, Jake, and Princess Bubblegum have left Ooo with to track down and stop the Ice King, who has managed to flee Ooo and enter the world to kidnap princesses. After finishing the Academy, Finn requests to see the hero in Orchid Bay to help him, Jake, and Princess Bubblegum save princesses who have been abducted by the Ice King. Once the hero arrives, he/she fools the Ice King into believing that the player is the television repair man, and he lets him/her into his palace and the hero finds the gang in his Basement. There, the player is told of the gang's plan to rescue the kidnapped princesses because the Ice King managedto capture both Candy wife and Princess after his arrival. Once the hero is filled in about the plan, Bubblegum sends the player to save the first princess: Candy Wife.
After the hero completes the task for Princess Bubblegum, Finn requests the player's assistance for the next part of their heroic plan. He seems to have over heard The Ice King called her "Princess Princess," so he guesses that means she's even more of a princess than Bubblegum. Princess Bubblegum seems to be a bit jealous for some reason, thus meaning that he can't rescue Princess. The hero then sets out to rescue her from a prison inside a giant ice cavern through a dungeon door. Inside, Finn tells the hero to hop down off the platform he/she is standing on (via NanoCom) and take out some of the Glacial Golems below, and make his/her's way to Jake, who has said that he'll meet the hero on the other side of the cavern to help him/her out. After the hero talks to Jake, he waits the hero to hop on his back so he/she can jump onto the fastly-moving floating ice platforms. When the hero eventually reaches the prison platform, he/she must defeat a giant Ice Titan to clear the way. After defeating the Ice Titan, the hero rescues Princess. Once freed, Princess shows ungratefulness towards the heroes actions. She ask him/her, "What took you so long! I'm freezing and I'm not getting any younger!" After saving Princess, she states,"I don't need your help getting out of the Ice Dungeon and tell whoever (She does not know who sent the hero) who sent you to next time send someone with brains!" The hero then leaves Princess, and heads back to Finn for a reward. Unlike Morbucks, Finn is grateful for the hero's help and states that, he doesn't know why Bubblegum is jealous of her and she's like an ogre in princess's clothing. 
Search for StanleyAppearently, Stanley seems to have stumbled into a forbidden dungeon hole. Once again Finn needs the hero's help, and the hero enters the magical portal in the Eternal Vistas. Once inside, Finn is waiting for the hero in the dungeon. If the hero can survive the deadly traps, evil creatures and hidden chambers of the Mystery Dungeon, Stanley might just offer him/her some totally mathematical new items!
Magical snails from the Land of Ooo have inched their way into . Legend has it that each snail will transport a person to a magical glade and bestow upon you a truly algebraic prize: exclusive Adventure Time gear! It would seem they hitched a ride with Finn, Jake and Princess Bubblegum when they set out for the world.
Nano DevelopmentFinn seems to have given DexLabs a sample of one of his personal items for Nano creation. His Nano is the first that can be received for new players, being the basic "tutorial" nano mission for most players. Additionally, a code can be used to redeem a Finn Nano Capsule, which is used primarily for players that survived the Future.
Cadet TrainingAfter, Dexter first discovered Fuse's invasion during a time travel experiment that sent heroes to the Future. They returned to the Past to warn of the coming invasion. As a result, the heroes of earth banded together to form the Academy and train recruits in the skills and tech required to defeat Fuse. Thanks to their efforts, that apocalyptic Future no longer exists. DexLabs, the Plumbers, and Providence have create the new traning system training, many heroes have signed up to help out. As one Finn has chosen to help. In the Providence "Petting Zoo", Lance, Rex, Finn, and Computress have taken the task to oversee the work of the new cadets in this area. During the training, Rex sends the recruit to defeat 1 Jumbo Fusion Spawn, after doing that the recruit must talk to Finn, by using a jump pad to get to him. The recruit then must defeat 5 Cyber Stingers. Once they are defeated the recruit returns to Finn for his/hers' reward. In another training mission, Finn sends the recruit to talk to Lance in the armory. Lance orders the recruit to defeat 7 Cyber Stinger. After again completing his/hers' mission, the recruit must return to Lance for further training.  
Cadet GraduationAfter the training courses, the recruit finally completes his/hers' training and thus earning the title "Hero". On Mt. Neverest, many heroes come to congratulate the recruit. Finn is present at the event. As he praises the hero and states that it was fun working with him/her. After the hero completes the 4 missions computress gives him/her, the hero must leave Mt. Neverest on Lady Rainicorn to journey to Sector V, for the start of their quest.
Tales of magical treasure chests being discovered and offering up fantastic gear have come from all across the land. Normally, the heroes would say that's just some crazy legend, but the rumors have been confirmed by none other than Finn the Human and his pal, Jake. They believe that the chests appear in random places and only stay for a short time before disappearing again. Where they go and what they may contain seems to be a mystery.
Sometime later during the war, Jake came to suspect Finn was up to something. He claims that he saw him sneaking off the a few nights ago and looked mysterious. Soon the Enchiridion went missing! He also states the Finn was also glowing green. Jake request that hero assists in sloving the mystery. The hero talks to Finn, but Finn seems completely lost and confused on what the hero is talking about. He suggest he/she go talk to Princess Bubblegum about this, and see if she saw anything. The Princess, confesses that see saw Finn down by a mysterious passage a few nights ago. Jake contacts the hero (via NanoCom) to find the passage. Once the hero finds it Jake request that he/she go in an investigate. The hero climbs the ice carvens until he/she reaches the ledge. The hero then defeats defeats 5 Glaciar Golems. Jake soon finds out the the Ice Titan have the Enchiridion, and lets the hero defeat them for it. It is soon discovered that Fusion Finn stole the Enchiridion. The hero defeats the Fusion, and restores the trust between the friends.
He has own statue in the Hero Square monument in Sector V (Future and Past). His statue shares the monument with exquisite statues of Rex, Ben, Finn, Chowder and Flapjack decorating the top area. Jake has jumped in to help heroes scale this great new monument in Sector V.
Finn, Jake, Princess Bubblegum, and The Ice King were added to the game on May 26, 2010. They arrived with three new missions, and two new dungeons, the inside of the ice kings palace and a bunch of great new Adventure Time items as well as new monsters to contend with. The Finn hat was bought back on the same day as the day these new NPCs were added.  On August 16, 2011 Finn appeared in the Mystery Dungeon looking for Stanley. Stanley offered brand new Adventure Time shirts.  He became a statue in Sector V (Past and Future) on June 23, 2010, along with Rex, Ben, Chowder and Flapjack decorating the top area.  His Nanos was added to gamplay on February 16, 2011 as a part of the new beginning.
