Asgore Dreemurr

Lore & Background

Asgore and the monsters he ruled were driven into the Underground, a cave beneath Mt. Ebott, millennia ago by hostile humans and trapped there by a magical Barrier. Before the game's events, he and his wife Toriel had two children: Asriel and an adopted human named Chara. Both Asriel and Chara were ultimately killed by humans following an ill-fated plan to cross the Barrier. Seeking revenge on humanity, Asgore declared that he would collect the souls of any humans who fell into the Underground, intending to use their power to destroy the Barrier. However, unwilling to fully enact his plan, he chose to wait passively in his castle for the six humans who fell after Chara and Asriel, fighting them only when they arrived. Toriel, angered by his hypocrisy, decided to live alone in the Ruins.

Reader's Guide

Asgore first appears in Undertale, serving as one of the game's antagonists. He is a Boss Monster and the king of the Underground. He has killed six humans before the protagonist and intends to take the protagonist's soul as the seventh. In battle, he destroys the Mercy menu option, forcing the player to fight.

His health will not lower to zero upon defeat; at that point, the player can choose to kill or spare him. If spared, he is moved and decides not to break the Barrier. In the Genocide route, the player kills him in one hit. In Deltarune, Asgore appears as an NPC in a parallel universe.

He has divorced Toriel, while Asriel is still alive. He was formerly the town's chief of police but left for unknown reasons. He owns a flower shop named "Flower King." In Chapter 4, he attempts to make amends with Toriel but is rejected.

In Chapter 5, his flower shop becomes a Dark World, with him appearing as king in attire similar to his Undertale appearance. At the end of the chapter, it is revealed he has been burdened by guilt and self-hatred since an unnamed tragedy years ago, leading to his divorce. The Roaring Knight kidnaps him before the protagonists can stop them.
