WARNING: This article contain spoilers of the game: Undertale.
Frisk is the playable character and main protagonist of Undertale. After Frisk falls into the Underground, they embark on a journey to return to the surface. Frisk is the last of the eight humans to fall into the Underground after travelling to Mt. Ebott. Frisk is not the "fallen human" named at the beginning of the game.
Frisk's name is revealed in only the True Pacifist Route. The player can project their personality onto Frisk because much about them remains ambiguous. Frisk speaks to NPCs throughout the game, but the exact dialogue is not shown. NPCs dialogue boxes display "..." to show that the NPC is listening to Frisk, and some NPCs respond to questions that Frisk asks.
Depending on their actions, players can interpret Frisk as merciful or merciless. Some NPCs emphasize Frisk's kindness, understanding, and grace in the epilogue. Frisk is obedient and only disallows player input when they follow someone else's instructions, such as when Sans tells them to hide behind the conveniently-shaped lamp.
