Frisk

Frisk is the main protagonist and sole playable character of UNDERTALE. Frisk is the eighth human to fall into The Underground, which makes him a target of Asgore as acquiring Frisk's soul would give Asgore a seventh human soul that would allow him to break the barrier separating the Underground from the surface. Frisk's ultimate goal is to escape the Underground and return to the surface.

Not much is known about Frisk, as Frisk has no spoken dialogue in-game. Due to being a human, Frisk naturally possesses a high level of Determination, which not only allows his soul to persist past death, but also grants him the power to SAVE and allows Frisk to revert events back to a previous point in time. The game's route is determined solely by the player's actions as Frisk; if Frisk is merciful towards every monster, the game will progress through the Pacifist route, while if Frisk is completely merciless, the game will progress through the Genocide route, with the Neutral route being the option in between if Frisk shows characteristics of both. Based on the route chosen, Frisk will either succeed in escaping the Underground, help the monsters break the barrier and free them, or kill every monster in existence and ultimately cause the destruction of the timeline.
