Halotale is an AU in which every main monster is an angel, and all side monsters (enemies, minibosses, etc.) are all demons. Halo Sans is the laid back, powerful angel, and Papyrus is the weak, optimistic, hunter for humans (demon kid, angel child, etc.), other people in this AU are monsters such as Toriel and Asgore (who are the god/goddesses of the monsters), Undyne and Alphys, where both are angesl, and Mettaton who is the same as he is in the original Undertale, yet golden.

About the AU

The story of the AU revolves around all the monsters being either demons or angels, the Halo Angels have been sealed underground in Hell by the humans in fear they would steal their souls, and Frisk, who was raised by the corrupted humans of the surface, falls down into the underground, and chooses the path of evil or good. No gigantic changes besides the angel setting are made, with a few minor changes.


  • the Main Cast have turned into angels
  • the Side Characters have been turned into demons
  • Sans, Papyrus, and Mettaton are the only 3 with golden halos, apart from certain other monsters such as Grillby, River Person, Monster Kid, or Asriel.
  • The Underground actually has clouds in this AU.
  • Halo Sans is very wanting of becoming part of the Star Sanses (outside au canon)



Sans wears shiny shades of yellow and a gold halo floating above his ever smiling head. His pupils have turned into an orange-yellow color of some kind as well as pure orange sneakers/slippers. Sans is usually laid back and hilariously lazy, but at times he can become very energetic and bashful.


Papyrus is still the same naive, happy and spaghetti loving skeleton. Though he's more narcissistic and stronger. He's like always the younger brother and wants to capture a human. But this time around he wants to impress both Undyne and Asgore. He wears light and golden shades of yellow also with a golden halo hovering over his tall and ever smiling head.


Undyne is much more mean in this AU. She wears shining gold armor with large pointy shoulders sticking out. She has one golden tooth and a longer spear. Undyne becomes your friend much later, after Frisk meets Alphys. Undyne is far stronger than she is in classic Undertale.


Alphys is the same as she always is. She's shy and nerdy. She does wear a golden lab coat with a halo floating over her head.


Mettaton also is the same as he always was. Though he also is built to have a golden body, he's much stronger than in classic Undertale.


Asgore is the god of all the monsters in the underground. He wears a glowing golden and white cape with silver shoulders to match. His crown has one giant red ruby in the center and he appears more merciful in this AU.


Toriel is the former goddess of the monsters in the underground. She wears a golden robe with white sleeves and light orange embroidery.


Flowey is basically the same.




Also the same. She wears black and brown clothes. Her cheeks are more red and she has a sharp toothy smile.


Long ago, 2 races ruled over earth, angels and humans. One day, the humans sealed the angels underground with the demonic monsters of the underground. 10 years later, a child by the age of 12 climbed up to the famous Mt. Edeath. Eventually falling in, the child was raised by monsters and cared for well. One day though, the child died, and 10 years after that, a new child fell in after 5 others, eventually they made their way into the mountain, starting a new adventure.
