**Spirit** in *Friday Night Funkin'* is a vengeful and tormented soul trapped within the retro world of the Week 6 game level. Once a living person, Spirit now exists as an enraged and ghostly entity, seeking retribution for being imprisoned in the game by Daddy Dearest. After Senpai’s form shatters, Spirit emerges with a haunting presence, filled with malice and sorrow. His appearance is unsettling, with a distorted, ghastly face, and his voice is chillingly distorted, conveying his pain.
