This article is about the Finn Sword. You may be looking for Finn's swords.

The Finn Sword is created in "Is That You?" after Finn sacrifices an alternate version of himself to save Prismo. After visiting a much more elaborate version of Prismo's Time Room, created as a "Plan B," Finn makes a choice to save Prismo by creating a paradox that vaporizes his dream world duplicate. Instead of turning to dust, Finn's body turns into a sword, dubbed the Finn Sword by Prismo.

The Finn Sword next appears in Breezy when Finn awakens to Breezy's final song. However, instead of seeing Breezy in her Queen form, he has a vision of Princess Bubblegum holding the Finn Sword.

In I Am a Sword, it was lost until being found by Bandit Princess, who used it to steal gold and kill people. Finn accidentally stabs the Finn Sword with the Grass Sword, rendering it inactive. The Finn in the sword is seen at the end of The Music Hole, suggesting that the sword's inactivity is the alternate Finn's choice rather than actual destruction.

In "Reboot" the grass sword once again touches the Finn Sword. This results in creating a strange grass humanoid. Due to having Finn's memories he later takes on the name and personality of Finn but starts to become a different person being known as Fern. Fern was killed (shattered into grass pieces) in Three Buckets, but was resurrected by Gumbald as seen in the episode Seventeen.

After Fern's destruction in Come Along With Me, his remains take the form of a seed shaped like the Finn Sword. That night, Finn and Jake plant the seedling together, which causes a massive new tree to sprout with a remade Finn Sword loged in the top. Many years later into the distant future, Shermy and Beth find the sword on the top of the tree.

Abilities

The sword is first used in Dentist and is shown to have Finn's dream world duplicate trapped inside of it and able to speak directly to Finn from the blue sphere it is encased in. In "Crossover," it is shown that other characters besides Finn are able to hear Finn Sword's voice. Also, while Finn is using this sword in battle, his physical attributes are double what they are without it. This is more than likely linked to the dream world duplicate inside it.

It still unknown which mystical attributes, if it does have them, the restored Finn Sword born by Fern's seed after a millennium has, and if they will work with Shermy, its current owner and possible reincarnation of Finn himself.

Trivia

  • The Finn Sword and Grass Sword merged together, creating Fern. Technically the Grass Sword was used to make the Finn Sword, as the alternate Finn had the grass sword in his right arm when he became the sword.
