Similar to Toriel and Asgore, Asriel has long ears, a snout, and visible fangs. In his initial form, he wears a green, long-sleeved shirt with yellow stripes and black pants, similar to the First Human's clothing. He also has a small wisp of fur on his head and lacks horns.
God of Hyperdeath
This form is named directly in the game, where the "Check" option labels Asriel as "the absolute GOD of Hyperdeath!" His scleras become black, his fangs become longer, and he has a pair of horns. He wears a long, dark robe with white sleeves and the Delta Rune on the front, with a large collar and shoulder pads. This robe is similar to Toriel's. He also wears a locket similar to the Heart Locket.
Asriel's body becomes more geometric, his horns are longer, and his teeth get sharper. He has a pair of wings that continuously change color, and his lower body becomes sharp and heart-shaped.
While this form is not directly named, it resembles the Delta Rune, which looks like the "Angel of Death" from the prophecy.
Before his death, Asriel was a docile, unadventurous, and loving child. He cared for the First Human as a sibling, and he trusted them when they came up with a plan to escape the Underground that involved them consuming buttercups.
After temporarily regaining his compassion, he apologizes for his actions to Frisk and realizes the gravity of his actions as a flower.
Much like his father, he speaks using southern slang.
Before the events of Undertale, Asriel found the fallen human, who was the first human to fall into the Underground. They became his adoptive sibling and best friend. Just before the human died, their last wish was to see the golden flowers of their village, on the Surface. Asriel absorbed their SOUL, and the human carried their own body across the barrier to their home village. Asriel and his sibling shared control of Asriel's body after their SOULs had combined.
The villagers assumed that the Asriel/Human fusion had attacked and killed the human child. The Asriel/Human fusion did not fight back but only fled. Lethally wounded, the Asriel/Human returned to the Underground and died. Once deceased, Asriel's body turned to dust, which spread across the garden in New Home.
Later, just before the queen left, Alphys injected determination into one of the garden's golden flowers-- the first one to bloom after Asriel's death. Initial experiments on the flower vessel proved unsuccessful, and Alphys returned it to Asgore. Once Alphys replanted the vessel, Flowey awoke within the garden.
Though Asriel's essence from the garden bed granted Flowey Asriel's memories, he soon found that neither his mother nor father could elicit any emotional response from him. He did not have a SOUL and thus could not feel love, joy, or compassion.
Asriel does not appear during a Neutral Route.
However, when the protagonist falls into the Garbage Dump, the protagonist hears Asriel's sound bite during a memory from Asriel's human sibling. Monsters also tell the story of Asriel and the first human during the walk in New Home.
|The Story of Asriel and The First Human|
This is the story told by monsters at the end of a Neutral Route. The song "Undertale" plays during this sequence.
True Pacifist Route
In the True Lab, the protagonist discovers that the first human and Asriel had worked together on a plan to get to the Surface and retrieve six human SOULs. While the human was on their deathbed, Asriel informed them he did not think it was a good plan anymore; ultimately, this leads to him betraying his sibling and aborting their plan.
After restoring the elevator's power, the protagonist receives a phone call from someone whose voice they have never heard before; the sound bite is similar to Asriel's.
After Flowey absorbs all monster SOULs and the six human SOULs, he transforms into Asriel.
Asriel greets the protagonist as <Name> before he transforms into "ASRIEL DREEMURR, God of Hyperdeath." He informs the protagonist that he does not care about destroying the world anymore, and instead just wants to reset the timeline so that everything unfolds again from the beginning. Asriel believes that the protagonist will continue even if he resets the timeline because they want a "happy" ending.
He then says that his first form is just a fraction of his real power and transforms into his final form. Asriel reasserts that the protagonist will die in a world where nobody remembers them as their physical body fails them.
The protagonist calls to the Lost Souls inside of Asriel's SOUL and reminds them that they are friends with the protagonist. After all Lost Souls regain their memories, the protagonist realizes that someone else needs saving. The protagonist calls their name, and a few sepia tone pictures display. The pictures are of Asriel and his sibling together when the human first fell into the Underground.
Asriel begins crying and reverts to his original form. After finding out that the protagonist's name is "Frisk," Asriel tells them that the monsters really love them and apologizes for his actions. He then breaks the barrier.
He tells Frisk that he has to go; Frisk has the option to hug Asriel and comfort him before he leaves. As he walks away, Asriel tells Frisk to take care of his parents for him.
Asriel is at the flowerbed in the Ruins. Frisk only encounters him immediately after his boss fight; if the player watches the True Pacifist Ending Credits and reloads the game, Asriel does not appear. Asriel speaks extensively to Frisk and offers them a different philosophy than his flower counterpart: "Don't kill, and don't be killed." He also mentions to be careful on the Surface because "there are a lot of Floweys out there."
|Asriel's Epilogue Dialogue|
After the credits sequence, when reopening the game, Asriel returns as Flowey and begs <Name> to "Let [Frisk] go" and allow everyone to live their lives.
After the protagonist kills Toriel, Flowey tells them that they are not really human, and mistakes them for the first child, telling them that they are still inseparable after all those years.
When the protagonist reaches New Home, Flowey welcomes them and discusses his backstory as a flower and how he discovered his ability to SAVE. Near the end of his dialogue, he realizes that the protagonist will not hesitate to kill him, and he is frightened for his life. He rescinds his previous plans with the protagonist and tells them to leave him alone.
|Flowey's Genocide Route Dialogue|
After the protagonist defeats Sans, they easily kill Asgore. Flowey destroys Asgore's SOUL and pledges himself to the protagonist one final time in an attempt to save his own life, revealing his true identity as Asriel in the process. He cries and begs the protagonist not to kill him, to no avail.
- For an in-battle description, see Asriel Dreemurr/In Battle.
In the True Pacifist Route, Asriel mistakes the protagonist for the first human and calls them his best friend. After the final boss fight, Asriel realizes that Frisk is not the first human and asks what their real name is. He later tells Frisk, if they backtrack to the flowerbed, that he does not regret his decision of resisting his sibling and, ultimately, getting them both killed.
The First Human
After the human carried their own body to the Surface, Asriel resisted his sibling's desire to unleash their full power, and humans fatally wounded them. With the first human's empty body in his arms, Asriel returned to the Underground and collapsed. His dust spread over the flowerbed in his dad's garden as he died. Even after becoming Flowey, he could not think of a world without them, as they are the only person that understands him and that is unpredictable to him.
Asgore is Asriel's father. When Asriel first woke up as Flowey, Asgore was the one to find him. Asriel informs Asgore of his identity, hoping to feel something and possibly turn back into his original form. However, having lost his SOUL, he discovers he feels nothing for Asgore any longer. Asgore believes that letting the protagonist escape the Underground with his SOUL is what Asriel would have wanted.
Asriel's habit of saying "gosh," "golly," and "howdy" may come from Asgore.
Asgore is unaware that Flowey is Asriel.
Toriel is Asriel's mother. In older timelines, after failing to feel anything with Asgore, he had turned to Toriel in hopes of feeling love again with her. This ultimately failed, as he could not love others without a SOUL.
Toriel is, like Asgore, unaware that Flowey is Asriel.
Alphys unintentionally created Flowey as a result of the determination experiments, but there is no indication that she knew Asriel in life.
- Asriel's general appearance and green shirt resembles the race of "Mimigas" from the indie game Cave Story.
- Asriel's name has several possible meanings or origins.
- Asriel's name is a combination of his parents' names, Asgore, and Toriel, likely stemming from Asgore being terrible at naming things. An interesting thing to note is that this follows Anglo-Saxon naming traditions, from where the English language imported names like Albert, Edgar, or Wilfred.
- "Asriel" might be derived from "Azrael," the angel of death in the Hebrew Bible. Gerson mentions an Angel of Death in his explanation of the Delta Rune prophecy.
- "Asriel Dreemurr" is an anagram of "serial murderer."
- "Dreemurr" is similar in pronunciation to "Dreamer," alluded by the ACT "dream" in his battle, and his leitmotif "Hopes and Dreams."
- "Asriel" is also a name of Hebrew origin that means "Helped by God." This might be a reference to Asriel being miraculously saved and turned to a flower after dying or helping Frisk by breaking the barrier with his god-like powers. This name appears several times in the Tanakh, the equivalent to the Christian Old Testament.
- His name and appearance could have also been inspired by Sariel, from the game Touhou: Highly Responsive to Prayers. Their names are similar, and this character's outfit resembles the God of Hyperdeath's (it also bears a symbol similar to the Delta Rune). Sariel is also an angel of death.
- His name may come from Lord Asriel, a character from the His Dark Materials series. Lord Asriel from the series has "enormous determination and willpower" which correlates with the theme of Undertale: Determination.
- When attempting to name the Fallen Child "Asriel," the response becomes "..." and prevents the name from being used.
- Both Undyne the Undying's armor and Mettaton NEO's body closely resemble Asriel's Angel of Death form, displaying a heart on the chest (and both gloves in Undyne's case), large, spiked shoulder pads, and, in Mettaton NEO's case, enormous, vibrant wings.
- Napstablook is the only known monster whose SOUL was not absorbed by Asriel.
- If the game is hacked, it is possible to spare Asriel Dreemurr during his boss fight, and the protagonist will be left on overworld where they left off: in front of Asgore, with the six souls. Nothing will happen, and the protagonist can walk around and even above the barrier.
- It is possible that Asriel inherited his father's trait of being bad at coming up with names, as when he is in his flower form he names himself "Flowey."
- ↑ "I... I don't like this idea, <Name>. Wh.. what? N-no, I'm not... ...big kids don't cry. Yeah, you're right. No! I'd never doubt you, <Name>. ...Never! Y... yeah! We'll be strong! We'll free everyone. I'll go get the flowers." - Asriel, True Lab VHS
- ↑ "As a flower, I was soulless. I lacked the power to love other people. However, with everyone's souls inside me... I not only have my own compassion back... But I can feel every other monster's as well." - Asriel
- ↑ "I acted so strange and horrible. I hurt you. I hurt so many people. Friends, family, bystanders... There's no excuse for what I've done." - Asriel
- ↑ "They were the one that picked up their own empty body." - Asriel
- ↑ "Frisk, when <Name> and I combined our SOULs together... The control over our body was actually split between us." - Asriel
- ↑ ENTRY NUMBER 8: I've chosen a candidate. I haven't told ASGORE yet, because I want to surprise him with it... In the center of his garden, there's something special. The first golden flower, that grew before all the others. The flower from the outside world. It appeared just before the queen left. I wonder... What happens when something without a SOUL gains the will to live?
- ↑ ENTRY NUMBER 15: Seems like this research was a dead end... But at least we got a happy ending out of it...? I sent the SOULS and the vessel back to ASGORE. And I called all of the families and told them everyone's alive. I'll send everyone back tomorrow. : )
- ↑ "I didn't feel anything at all. I soon realized I didn't feel ANYTHING about ANYONE. My compassion had disappeared!" - Flowey
- ↑ "It sounds like it came from over here... Oh! You've fallen down, haven't you... Are you okay? Here, get up... ... <Name>, huh? That's a nice name. My n a m e i s... - Asriel, upon finding the human.
- ↑ "They were the one that wanted to... ...to use our full power. I was the one that resisted. And then, because of me, we... Well, that's why I ended up a flower." - Asriel, epilogue
- ↑ "I don't care about destroying this world anymore. After I defeat you and gain total control over the timeline... I just want to reset everything. All your progress... Everyone's memories. I'll bring them all back to zero! Then we can do everything ALL over again." - Asriel
- ↑ "And you know what the best part of all this is? You'll DO it. And then you'll lose to me again. And again. And again!!! Because you want a 'happy ending.' Because you 'love your friends.' Because you 'never give up.'" - Asriel
- ↑ "Wow... You really ARE something special. But don't get cocky. Up until now, I've only been using a fraction of my REAL power! Let's see what good your DETERMINATION is against THIS!!" - Asriel
- ↑ "Can't move your body. Nothing happened. You struggle... Nothing happened." - Narrator
- ↑ "But I can feel every other monster's as well. They all care about each other so much. And... they care about you too, Frisk. I wish I could tell you how everyone feels about you." - Asriel
- ↑ "Frisk... I... I understand if you can't forgive me. I understand if you hate me. I acted so strange and horrible." - Asriel
- ↑ "Well... My time's running out. Goodbye. By the way... ...take care of Mom and Dad for me, OK?" - Asriel
- ↑ "So, please. Just let them go. Let Frisk be happy. Let Frisk live their life." - Flowey
- ↑ "You're not really human, are you? No. You're empty inside. Just like me." - Flowey
- ↑ "You're <Name>, right? We're still inseparable, after all these years..." - Flowey
- ↑ "After all, it's me, your best friend! I'm helpful, I can be useful to you. I promise I won't get in your way." - Flowey
- ↑ "I can help... I can... I can... Please don't kill me." - Flowey
- ↑ "I did the right thing. If I killed those humans... We would have had to wage war against all of humanity." - Asriel
- ↑ "Over time, ASRIEL and the human became like siblings. The King and Queen treated the human child as their own." - Neutral Ending Dialogue
- ↑ "I'm sorry... I couldn't give you a simple, happy ending... But I believe your freedom... ...is what my son... ...what ASRIEL would have wanted." - Asgore
- ↑ Num 26:31; Josh 17:2; 1 Chr 7:14 (KJV)
