Asgore Dreemurr is the ruler of the Underground and its denizens, monsters. He is the ex-husband of Toriel, father of Asriel Dreemurr, adoptive father of the first human, and the penultimate boss of the Neutral Route. While not evil or malicious, he serves as one of the main antagonists, planning to kill seven humans and use their SOULs to break the barrier which traps the monsters in the Underground.

This war has gone on long enough. You have the power... Take my soul, and leave this cursed place.
Asgore is a kind monster that enjoys gardening, Golden Flower Tea, and Toriel's Butterscotch Pie. Like his son, he speaks in southern slang (most notably "howdy" and "golly"). Before his battle, he offers the protagonist many opportunities to explore the Underground and is reluctant to fight them at all; he even suggests that Toriel, the protagonist and himself live as a family if the protagonist spares him.
Monsters in the Underground look to Asgore for hope, and his plan to collect seven human SOULs is one of the few things that keep them going. However, Asgore does not want to kill anybody and feels so guilty that he offers the protagonist his SOUL to "leave this cursed place." Though he is miserable because he has killed humans, he feels that it is his duty to his people to battle the protagonist.
Asgore lives in the past and wants nothing more than to see his wife and child again, even though they have been gone for a long time. He reiterates the same phrase in his journal every day, perhaps in denial that life has changed since Asriel's demise.
Monsters also note that he is bad at naming places, with the names being quite literal (such as naming the monster's first home in the Underground "Home", and naming their new home "New Home"). Gerson suggests this may be because Asgore is not the most intellectual monster, with the smarter member of the royal family as well as the one which was actually running the city being Toriel.
Appearance
General Description:
Asgore is a large Boss Monster and the tallest main character in Undertale. He has two large curved horns, a golden-blond mane, a golden-blond full beard, white fur, long ears, a snout, and a set of visible fangs.
Clothing/Outfit:
Battle Armor: A small, three-pointed crown atop his head. Golden pauldrons. A long purple cape that slightly drags along the ground, often used to cloak his armored body. Near-full body armor with a large chestplate featuring a winged crest of the implied "angel" from the Delta Rune emblem. His tasset visually resembles the triangles of the emblem. His feet are unarmored.
True Pacifist Ending Credits: A white flower-patterned, pink Hawaiian t-shirt. Long purple pants. He retains his crown.
Items:
A sharp red trident adorned with a six-petaled flower at its base.
Physical Traits:
In the True Pacifist Ending Credits, he is shown to have golden-blond arm hair on his forearms, muscular arms, and a notably rotund stomach, in contrast to his broad-chested armored appearance.
Personality
Kind: Asgore is kind, often quiet, yet upbeat. He speaks in southern slang, including "howdy" and "golly," similar to Asriel.
Interests: Asgore's interests include gardening, humming, making tea, going for walks, sparring with Undyne, dressing up as Santa Claus, and puns.
Sense of Humor: Asgore has a sense of humor, accepting being called "Fluffybuns" after Toriel accidentally nicknamed him in public. Correcting her teasingly by saying "That's KING Fluffybuns".
Bad Naming Sense: Asgore gives monster cities literal names, such as "Home" and "New Home."
Powerful Leader: Monsters respect Asgore as a powerful leader. His name is always fully capitalized, sometimes in red or yellow text.
Give Hope to Others: Asgore fights humans only to give hope to monsterkind. He feels miserable for the deaths of the six humans, does not want to kill anybody, and feels guilty for declaring war on humanity.
Lives in the Past: Asgore lives in the past and only wants to see his wife and Asriel, even though they have been gone for a long time. He writes the same short positive phrase in his journal every day. He tries to bake Toriel's Butterscotch Pie multiple times.
Toriel is Asgore's ex-wife. Before their separation, the couple won first place in the '98 Nose Nuzzle competition, and were described by Gerson as being "insufferable together, nuzzling noses, bein' all cute n' cuddly." Their relationship ultimately fell apart following the deaths of their children and Asgore's declaration of war on humanity.
After Toriel left, Asgore appeared to deeply miss her presence. A "Room under renovations" sign was placed on her door in his home, and multiple crumpled pie recipes suggest he attempted to recreate her butterscotch-cinnamon pies—though he could never quite replicate them. This stands in contrast to Toriel, who continues making her pies and maintains only low-maintenance plants in her home. His lingering attachment is further evidenced by his reaction when the protagonist eats Toriel's pie during his battle. After being defeated, he expresses a desire to see his wife and child again.
When Toriel interrupts the battle between Asgore and the protagonist, she chastises him for his plan to collect human SOULs and turns down his request to be friends again, leaving him sorrowful. However, after the fight against Asriel—where their SOULs are saved as one—her hostility toward him appears to soften. In the True Pacifist Ending, Asgore can be seen trimming the bushes in front of Toriel's school.
When Undyne was young, she met Asgore in person and challenged him to a fight. After Asgore defeated her by dodging all her attacks without landing any of his own, he offered to train her. When she finally managed to knock him down, Asgore was overjoyed—much to Undyne's surprise. He continued training her until she became captain of the Royal Guard.
Undyne is familiar with Asgore's preferred tea and knows that he often gets marshmallows stuck in his beard when drinking hot cocoa, implying that he frequently visits her home.
Gerson
Gerson implies that he and Asgore have been long-term friends, though it is unclear how long Gerson served as a hero to monsterkind. Gerson recalls Asgore's simple naming style and various moments from his life, such as when Toriel called him "Fluffybuns." Gerson appears to be the only monster in whom Asgore confided his pessimism about freedom and humanity's willingness to trust monsters.
Alphys
Asgore hired Alphys after she impressed him with Mettaton. He is friendly toward her and places complete trust in her Determination research. He supported her efforts by providing monsters who had recently "fallen down," and allowed her to experiment with the captured human SOULs. Asgore also kept in touch with Alphys through messages—both formal and casual, such as one about finding a teacup that resembled her. However, he remained unaware of the true nature of her research progress.
In the True Pacifist Route epilogue, Asgore remains on friendly terms with Alphys. He expresses interest in anime after overhearing Undyne and Alphys's conversation, and readily forgives and comforts her when she admits the truth.
Asriel was Asgore's biological son, whom he loved dearly—just as much as he did the first human. Asriel's habit of using words like "howdy" and "golly" likely came from his father, as did, potentially, his lack of naming skills (having dubbed his flower form "Flowey"). After Asriel's death, Asgore was deeply saddened. He did not realize that Flowey was his son. In one of the paths where Asgore sacrifices himself, he states that this is exactly what his son would have wanted.
Chara was Asgore's adoptive child, whom he loved just as much as Asriel. He considered them to be "the future of humans and monsters"—a sentiment repeated on the Game Over screen, in VHS Tape 5, and when the protagonist sleeps in the bed at Toriel's Home. It is implied that he may have believed the first human was the Angel spoken of in the Delta Rune prophecy.
During the Genocide Route, Flowey states that despite trying "hundreds of ways" to get Asgore to show him the six human SOULs, he is confident that the first human can persuade Asgore to do so.
Asgore is polite and friendly toward the human, despite them being human. He attempts to comfort them on multiple occasions and tells them to take their time before their battle.
When the human proceeds, Asgore says he was pleased to meet them and bids them farewell before initiating combat. If the human uses the "Talk" ACT, Asgore falters but continues attacking. If they explain that they have died before, he acknowledges this with a regretful nod but persists in battle.
Upon defeat, Asgore expresses his regrets and tells the human to take his SOUL to leave "this cursed place." If the protagonist spares him, he questions their reasoning, then suggests they could live together with Toriel as a family. If Asgore was spared on a previous playthrough, he instead admits he believes the human is the Angel of the Delta Rune prophecy. With remorse, he sacrifices his SOUL to them in hopes that they will find the truth.
In the True Pacifist Route epilogue, Asgore properly offers the human tea. After seeing the Surface, he asks if they would be willing to serve as monsterkind's ambassador to humanity.
On the Genocide Route, Asgore does not recognize the human as a human and questions what kind of monster they are.
Status:Alive in True Pacifist Route, Deceased in Neutral Route and Genocide Route (Killed by The Human in both routes)
Alignment:Neutral Good (Despite being responsible for the deaths for six humans, the reasoning was to get his people out of the underground and out of anger for the death of both of his children, after this he has shown to be a very nice man that cares greatly for not only his people, but even humans, going as far as to concede in battle and let the human take his SOUL to pass through the barrier)
Knowledge: At least Master level (Serves as the leader of the Underground, with his decisions overriding that of even the most intelligent monsters. Constructed a plan to free the Underground by destroying the Barrier. Has lived before written history, giving him over 10,000 years of experience and knowledge. While naive in some things, he is incredibly skilled in battle)
Trident, 6 Human SOULS (Thought he won't absorb them unless necessary)
Notable Techniques
Fire Magic: Asgore appears to have a mastery over fire, using it for numerous techniques. These include calling down undulating waves of fire, creating enormous, inescapable walls of fire, circles of fireballs which close in on his opponent, creating large trails of fireballs which track his opponent, and creating enormous bursts of dozens upon dozens of fireballs which are immensely difficult to dodge.
Trident: Asgore has shown to be extremely proficient with his trident, swiping it across the battlefield in an attempt to hit his opponent. The trident will leave behind trails of magic, making it impossible to dodge by conventional means. When the magic is orange, Asgore's opponent must be moving in order to not be hurt. When the magic is blue, his opponent must remain stationary.
Other
Standard Tactics: Asgore will begin by destroying the ability to pacify during the fight, using various magic attacks afterwards.
Unique Weaknesses: Asgore is naturally depressed and will hold back against an opponent if he feels he's wronged them (this usually refers to human children).
Explanations
Monster Check Stats
Monster's check stats are quite dubious for a couple of reasons:
Note: Asgore was already severly depressed to the point that he is willing to kill himself just for the Human to take his SOUL to escape the barrier[44]. Which it's already noted that monsters stats drop when they don't want to fight. Seeing as Asgore has captured the previous six human SOULS which all had the same ability of SAVING, it's likely a full peak Asgore could beat the Human.
