King Asgore Dreemurr is the ruthless ruler of the Underground and one of the final bosses of the Underfell universe, as well as the main antagonist.
After the day his son and adoptive child died in one day, Asgore became devastated. He lost his mind and held an even more stronger grudge against humanity.
Before the death of his two children (Chara and Asriel) and the departure of his wife, his personality would be actually more similar to his Undertale counterpart. Kind, fatherly and caring. Now, after the death of his children, he declared a new rule, Kill or Be Killed.
Appearance[]
Asgore in Underfell has black hair and a beard, yellow scleroses with red pupils for his narrow devilish eyes, and a red cape with golden pauldrons that cover his dangerous armor. His horns are identical to that of a bull's, except instead of being curly, his horns are pointed up. Like his counterpart, his fur is white, but he has longer fangs. His weapon may be a flaming spiked meat cleaver, but this is not agreed upon across most versions. He is also a little taller than his Undertale counterpart.
Personality[]
Like most characters in Underfell, Asgore has a strong, negative personality compared to how he was in Undertale. He has an ultimate urge to kill humans. He was always known as a harsh king, especially after Toriel left him when he forced the 'Kill or Be Killed' rule onto everyone. He threatened to personally hunt down anyone who disobeyed him, so that every monster had to gain LV quickly to survive. It was at that time Asgore became much more cruel.
However, before the death of his children and the departure of his wife, he was much closer to his Undertale counterpart.
Fight[]
The End - This fight would be very similar to the fight in Undertale. Only, after a few words, you and [[1]] immediately enter the battle with Asgore in the Throne Room. After the fight, in the True Pacifist timeline, you lose control of Frisk would spare Asgore by force without choosing. Asgore is surprised, since everyone in the Underground tried to kill Frisk.
Omega Sans Battle[]
After finally sparing Asgore in Neutral Route, Sans would kill Asgore after he stole the human souls, becoming Omega Sans. This is similar to the Undertale Photoshop Flowey battle in the Neutral Run. (For more about Omega sans, enter this link)
