Humans



Humans are an endangered species in the post-apocalyptic setting of Adventure Time. It is suspected that Finn is the last human on Earth. Many characters have marveled at Finn's humanity, like Princess Bubblegum in the episode "Susan Strong." Bob Rainicorn even went as far as to say that he and his wife Ethel Rainicorn believed humans to be extinct. The scarce Human population in the Land of Ooo can probably be attributed to the Mushroom War, a war that took place some time before the present story line and is thought to have involved the excessive use of nuclear arms. Another possible cause for the scarce number of humans might be that the inhabitants of Ooo devoured the humans, as species such as Skeletons and Rainicorns have a desire for flesh.

Note that there are other beings in Ooo (such as Pajama Ninja or Old Man Henchman) that seem to resemble humans. However, Finn and the other characters do not recognize them as humans. According to the show's writers, these characters should be referred to as "humanoids" or mutants.

Though no longer humans, certain species on Ooo can be seen as connected if not formerly human themselves. These include various skeletons of dead humans found in places like the Land of the Dead or The Lich's Lair as well as possibly certain humanoid monsters such as the Hyoomen Tribe or the Businessmen. Vampires in particular are seen as former humans who crossed over into vampirism leading to longevity but turning them into monsters. Some vampires, such as The Lord of Evil, have further mutated beyond this humble stage into more demonic forms. Ghosts likewise appear to have certain beings which were formerly human before achieving their current form.
