The three are forced to run from the Lich, as he begins to destroy the Citadel. At this time, Martin flees, and Finn tries to give chase, but his grass sword takes over his entire arm, causing Finn to lose it.
Finn loses an arm twice, both times in dramatic circumstances: firstly, when unsuccessfully trying to stop his father from abandoning him once again, and secondly, when his organic arm replacement – the Grass Sword – is fused with his personality from an alternative timeline (encased in the Finn Sword) to create Grass ...
A flower blooms from the stump where Finn's arm used to be, and eventually grows into a new arm. He loses his control of his regrown arm, which transforms into a grass doppelgänger called Fern in the eighth season two-part episode "Preboot / Reboot".
Unfortunately, Finns father who was abord the ship at the time made a bigger portal. Soon, Finns grass arm was removed from his body. Up to his elbow, Finn now had no arm. However, Finns arm does grow back in the episode "Breezy" while him, jake, and Princess Bubblegum are meditating.
During Adventure Time, it was revealed that Finn and Jake were the same age, and the series ended when Finn was 17. Therefore, it would only make sense that Jake would pass away by the time Finn reached adulthood.
Status as the Last Human. Finn was, for a long time, the only confirmed human in the Land of Ooo, to the point where he had an epithet, "The Human", and was referred to by many as "Finn the Human".
Later, the reason Martin abandoned Finn is revealed in a flashback in the Islands miniseries where he and baby Finn are chased off from an island as a result of Martin's past con-artist ways. To protect Finn, Martin defeated the guardian that thought they were trying to escape the island on a raft.
At her tree, Jake teases Finn again about liking the Wizard, but Finn denies it and goes to sleep. In the morning, Huntress Wizard takes the two to a magic spring to drink from so they can be immune to the magic boar's lightning powers.
When the Citadel Guardian's blood got on the stub where Finn's arm once was, his arm didn't grow back, but it instead left behind a flower, which was likely a remnant of the sword. In "Breezy" it's revealed that the condition of the flower is based on Finn's emotional state.
Many decades have passed since the events of "Obsidian." Through a hallucination, it is revealed that Jake has passed away, which severely traumatized Finn. In this hallucination, Finn goes on an adventure that takes him back to his pre-teens, but things seem off.
The Guardian blood doesn't regrow Finn's whole arm, though, as it did for Martin and the Lich. Curiously, his arm sprouts a flower. This could be a result of the blood being a tiny blotch - Finn threw multiple globs at the Lich to subject him to the blood's full effects.
Also inconclusive is BMO's gender. BMO is a sentient computer in the shape of a walking handheld video game console (see fig. 5). Canonically, BMO has no gender and is referred to throughout the show by both masculine and feminine pronouns.
Finn wears an animal hat is to disguise the fact that hes a human. Why? Because humans are delicious. As for Hyoomans, they are mutated and not fully human, but they are human enough to be mistaken as humans, so maybe they taste the same, hence they wear hats too.

Finn the human is 17 years old at the conclusion of the show. However, we might expect an older version of him if he makes an appearance in Fionna and Cake! If you're looking for Adventure Time toys, we've got them here at Toynk!
Finn dances with Quilton's daughter, Roselinen. However, no one knows how to get him home. Years later, Finn and Roselinen have married and had two children, Bonnie and Jay. Quilton tells them that an ancient book has been discovered revealing that the door to Finn's world appears periodically.
Martin was originally supposed to appear in "The Lich" after Billy told Finn about him; he was a warrior who was unintentionally trapped in the Crystal Citadel, a prison that is difficult to enter and nearly impossible to escape.
However, during the fight, Flame Princess destroys the Ice Kingdom and discovers that Finn set up the fight. Feeling betrayed, she breaks up with him. "Frost & Fire" was the last episode of the fifth season to have been storyboarded by Pearson, although he later returned to revise the storyboards for "Earth & Water".
Shermy is confirmed to be a reincarnation of Finn, which makes sense considering their similarities and the fact that Finn can resurrect when he wants and be another living being due to being an incarnation of the Blue Catalyst Comet.
In Adventure Time Mini-Series: "Islands" it revealed that around thousand years prior to the main events of the series, a group of human survivors of the Mushroom War fled Ooo on a container ship (as seen in Stakes) to escape from the vampires, oozers, and other magical and mutated dangers.
His current biological age is 34, as stated by Steve Wolfhard in the Conversation Parade podcast, meaning that at some point his aging slowed down from when he was a puppy. Jake says in "Daddy-Daughter Card Wars" that he's lost track of how old he is, but thinks he might be almost 40.
