The Night Sword is Finn's main sword as of "Marcy & Hunson." It was created by Peppermint Butler as a replacement for Finn's small sword.


The Night Sword is an incredibly pointy sword with a low purple hue. Its hilt has two seemingly flat eyeballs on opposite faces of the sword and can flip out to reveal a built-in compass. The eyeball color appears to have a dim light-blue glow and is incredibly glossy. The sword is cursed since it was forged by Peppermint Butler and blessed with Nightosphere magic by Hunson Abadeer.


Not much is known about the sword yet, other than it being powerful, cursed, and harmful to ghosts.
