Fight Pacifist Simulator: Asgore
The fight begins with a subversion of the game’s core UI. For the entire game, the "Mercy" button has been your shield and your sword. Against Toriel, Papyrus, and Undyne, the path forward was to refuse to fight.
Asgore destroys that illusion instantly. With a swing of his trident, he smashes the player's "Mercy" button.
"I ask you to show yourself," he says, head hung low. "So that I may take your soul."
The Mechanical Shift: This is the simulator's first lesson. You cannot simply wait. In a standard RPG, a pacifist run usually implies inaction. Here, inaction equals death. Asgore forces the player to engage with the "Fight" command, not to kill, but to survive.
Asgore looks at Toriel. She approaches him slowly, then slaps him – but then hugs him tightly.
Toriel: "You fool. We have so much to talk about. But first… let's free everyone together."
Asgore nods. He holds out his paw.
Asgore: "Thank you, little one. For showing me that a monster can be more than their worst day. I… I would be honored to call you family."
🎵 His Theme plays softly
You won.
No one killed.
No one had to die.
The Barrier can be broken – with love.
The world is saved.
Would you like a version where you fail the pacifist route (e.g., accidentally attacking, or Flowey killing Asgore before Toriel arrives)?
Unlike the Toriel fight (where she stops attacking if you get low), the Asgore Pacifist simulator has a cruel twist: He will not spare you first.
You have to press the MERCY button while he is actively trying to kill you. And when you do? asgore fight pacifist simulator
"Asgore stops mid-swing. The fire in his hands extinguishes."
He falls to his knees. He admits he knew you were Frisk the whole time. He admits he saw Toriel's hope in your eyes. And then... he delivers the line that shatters every player:
"I just... I just wanted to see everyone happy again."
For the simulator to transition into the True Pacifist ending, the Asgore fight must be approached with specific prerequisites:
If these conditions are met, the fight with Asgore is interrupted not by death, but by the arrival of your friends. The fight ends not with a final blow, but with a frantic, chaotic family intervention.
"Asgore Fight Pacifist Simulator" (AFPS) is a fan-made concept blending Undertale's Asgore boss fight with pacifist-run mechanics, reimagined as a simulator where players experience Asgore-themed encounters while adhering to nonviolent/pacifist constraints. This report outlines concept, core mechanics, design goals, target audience, content structure, technical considerations, accessibility, risks, and suggested roadmap.
As of 2025, the perfect "Asgore Fight Pacifist Simulator" remains a myth. Most versions crash after the second phase. Some result in a silent black screen where Asgore simply walks away, leaving the barrier intact. Others trigger the "Soulless Pacifist" ending automatically.
But the desire for it is more important than the execution. It represents the player's refusal to accept a binary outcome. It says that even when a king has condemned you to death, even when the game mechanics scream "FIGHT," the human soul will look for a third door.
Until Toby Fox releases an official "True Pacifist 2.0" (which he has explicitly stated he will not do), the modders will keep coding. The fans will keep dreaming. And in the vast digital graveyard of Game Jolt and GitHub, the Asgore Fight Pacifist Simulator continues to glitch, crash, and occasionally—for just three seconds—display a single, golden line of dialogue:
"You... you really are like them. Alright, little one. I believe you."
And then, the simulation breaks. Because some monsters are programmed to fall, not to fly. But we keep trying anyway.
If you are looking to play a functional version, search for "Undertale: True Mercy Patch v0.4" or the "Dreemurr's Redemption" fangame. Note: You will likely need to patch your Undertale .exe to version 1.08 and disable your antivirus for the script injector. As always, back up your saves. The King’s judgment awaits.
The air is cold. Golden light streams through the stained glass. Asgore Dreemurr, King of the Monsters, stands before you. His massive trident is lowered, but his eyes are heavy with sorrow. The fight begins with a subversion of the game’s core UI
Asgore: "Human... you have come far. I cannot offer you mercy. Not yet. But... I will remember your kindness."
The battle begins.
Turn 1
Asgore raises his trident. A wall of orange and blue magic fires toward you.
Blue attack: Stay still.
Orange attack: Keep moving.
You hold your ground, dodging perfectly. You do not FIGHT. You ACT.
What do you do?
You choose: Talk
Your SOUL flickers gently.
Asgore: "You... wish to speak? After all I have done?"
His next attack is weaker. He hesitates.
Turn 2
He summons fire orbs that orbit the box slowly. You weave between them without getting hit.
What do you do?
You choose: Butterscotch Pie (from Toriel)
You hold up the pie.
Asgore freezes. His trident clatters to the floor.
Asgore: "That smell... T-Toriel's recipe..."
His hands tremble. Tears form in his eyes.
Asgore: "I have been so... afraid. Afraid to hope."
He does not attack this turn.
Turn 3
Asgore: "You could have killed me. Taken my SOUL. Freed everyone by force. But you didn't."
His remaining HP: 80% → 40% (his own hesitation is hurting him)
What do you do?
You choose: Console him – You say: "It's okay, King Asgore. Toriel still loves you. You don't have to do this alone."
Asgore falls to his knees. The battle box disappears.
Asgore: "Human... I surrender. I cannot... I will not kill you."
