Asgore Dreemurr is a character in the 2015 video game Undertale developed by Toby Fox, and its 2018 spiritual sequel Deltarune.

The moral dilemma of killing humans to help the monsters, as well as the similarities between the musical themes of Asgore and his wife Toriel, have made him the subject of commentary.

Unwilling to fully enact his plan, Asgore chose to wait and ambush them one by one rather than exit the Barrier with a single human soul and immediately claim six more.

During battle, he destroys the Mercy menu option on the user interface, preventing the human from sparing him and forcing them to fight to the death.

In the former option, the character Flowey, who had served as an antagonist in the beginning of the game, returns and kills Asgore instead before turning to fight the human.

Once these conditions are fulfilled, either from reloading an earlier save or starting a new run, the human's encounter with Asgore will be interrupted by Toriel and other characters.

In this parallel universe, taking place in a more standard town environment, Asgore has gotten a divorce from Toriel, while Asriel is still alive.

The Gamer writer Colby felt that Asgore was a bad person due to his actions and the thing he planned to do to Frisk, but could still understand why he did it.

[3] Kotaku writer Joe Parlock considered him among the best new characters of 2015, feeling that despite the cast of Undertale being so solid, none of them were as "endearing, tragic, or adorable" as Asgore.

"[5] Writer Jason Yu also discussed the shared thematic elements between Asgore and Toriel, including the gradual discovery of the relationship between them.

He also observed the similar ostinato, appreciating that it did not come into the song immediately, as he felt it would have given away the musical relationship between Asgore and Toriel too easily.

[10] Matthew Perez felt that the reuse of Toriel's musical motif was meant to demonstrate the struggle Asgore experienced with his actions.
