Clover is the main protagonist of Undertale Yellow. They are the seventh human to fall, and the sixth SOUL that is collected by Asgore Dreemurr in the Pacifist endings. Throughout the game, they venture in the Underground through old and new locations to reach the Surface.
Notably, unlike Frisk, Clover does not seem to have a bond with the first human. Due to this, the game automatically uses Clover as the protagonist's name instead of prompting them to name the fallen child.
