Finn Sword was made out of dream version of Finn, and consequently, it has all his heroic attributes and inclinations. The Finn Sword was a little different, however: in “Is That You?” Finn and Jake used alternate universe versions of themselves to revive Prismo. It’s a subtly mind-boggling episode that deals with self-knowledge, agency and objectification, and which sets up what should be the next big development arc for Finn’s character.Įvery one of Finn’s iconic swords has been the result of a moment of personal growth: the Demon Bloodsword was the prize at the end of “Dad’s Dungeon,” in which Finn received a posthumous thumbs-up from his adoptive dog father and the Grass Sword was a curse that became a powerful boon after Finn accepted its permanent addition to his body. It’s the eponymous time again! “I Am A Sword” riffs on the trope of the hero and his sword, with one unique twist: Finn is his sword, or rather, his sword was crafted from an alternate dimension of himself, which makes it sentient and endowed with all of Finn’s characteristics… it’s complicated! From the start, Finn Sword has been a mysterious artifact that never got too much attention, until now. On the latest episode of Adventure Time, “I Am A Sword,” Finn finds out what it means to lose himself, when he loses the Finn Sword to Bandit Princess and has to reclaim it.
