Asriel Dreemurr (also known as Flowey) is an antagonist turned supporting character in Toby Fox's indie RPG Undertale. He is the son of Asgore Dreemurr and Toriel and the adoptive sibling to Chara, the fallen human Asriel found and befriended. When he and his sibling made a plan to free their people, monsterkind, from the Underground they were trapped in, it backfired and resulted in both of their deaths.

Over the course of Undertale, Asriel, having renamed his resurrected form Flowey, turns from a villain seeking to rip the world away from the protagonist back into the mournful child he was trying to deny himself of being. 


Little is known about Asriel in life, but he seemed to be a mischievous and cheerful child from a loving family. He loved to play harmless pranks on his sibling, whom he trusted like nobody else. He mentions being a "crybaby". Despite his young age, his devotion to his people was absolute, and he was willing to plan murder and the death of his own sibling to free them. His kind heart could ultimately not bear the burden, however, and at the last moment he realised it was only the bravado of a child with too much responsibility on his shoulders. He decided in the end that he would rather die than kill anyone, and ended up crumbling to dust in his parents' arms because of it. When he found himself resurrected without what seems to be one of his most defining traits - his ability to feel compassion - he was lost and terrified. Over a long time spent trying desperately to feel something he hardened himself into everything he had died to prevent becoming, plunging himself into deep trauma and depression. At the end of the game, he has at last been broken out of his endless cycle. Now he eschews all violence once more, and while still empty is trying his best to be kind again.  


Asriel is a Boss Monster, a goatlike, bipedal creature with large paws instead of hooves. He is a small child who wears green-and-yellow striped shirts and is seen in the game wearing dark blue trousers, possibly jeans. He has a short snout with two small fangs poking out of its tip and a scruff of hair atop his furry head. His fur is white, his ears long and floppy much like a lop rabbit's. While in possession of a heart locket to match his sibling's, his child form does not wear it in the game; he only wears it in one of his two 'boss' forms. 

Resurrected, Asriel takes the form of a golden flower with a face capable of morphing into grotesque shapes.  With the power of souls, Asriel also takes three additional forms.

His Past

Toriel And King Asgore The King And Queen Of The Monsters After A War Against The Humans It Forced All Monsters Underground Sealed Away With A Magic Barrier he Lived His Childhood Separated From Humans However When A Child Fell Into The Underground His Family Adopted Them As Their Own He Soon Became Friends With The Child And The Two Of Them Would Do Anything Together

Some Time Later The Child Became Deathly Ill And Told Asriel Of Their Desire To Be Returned To The Surface And Buried In Their Home Village Taking His Siblings Soul Asriel Was Able To Breach The Barrier And Enter The Human World But When Seen By The Humans He Was Accused Of Killing The Child And Was Attacked Despite Having Immense Power From Both A Human And A Monsters Soul He Refused To Fight Back And Returned To The Underground Before Dying Over A Field Of Golden Flowers It Later Became Clear That The Child Poisoned Themself As Part Of A Plan Devised With Asriel To Gather Six Human Souls And Wished To Use Their Combined Powers To Kill The People In The Village

The scientist Alphys later used a powerful substance, determination, harvested from the souls of six other fallen humans on the flower Asriel's dust was spread on during her research into other ways to break the Barrier keeping the monsters trapped. While she did not know, this resurrected Asriel as a soulless husk with emotions so numbed it was as though he could no longer feel compassion. His newfound determination gave him the power to reset the timeline, which he did over and over until he felt like the world was little more than a game.
