Disclaimer: I do not own Undertale or any of its characters
Author's Note: This is another one of those au's where the characters roles are completely switched around. Except I think mine is more random, also the characters keep their original personalities and relationships. Sans is still Papyrus' brother, Toriel is still Asriel's mother, etc. And if it turns out to be exactly the same as another au, it's purely coincidence. I'll list all the switches below… skip it if you wish to be surprised.
Sans takes on Flowey's role
Papyrus takes on Toriel's role
Toriel takes on San's role
Asgore takes on Gaster's role
Undyne takes on Asgore's role
Alphys takes on Muffet's role
Mettaton takes on Undyne's role
Flowey takes on Mettaton's role
Muffet takes on Papyrus' role
Gaster takes on Alphys' role
Napstablook and Mad Dummy switch roles
Temmies and Froggits switch roles
And no more swapping or my mind would explode from all the information.
Long ago, two races ruled over Earth: HUMANS and MONSTERS. One day, war broke out between the two races. After a long battle, the humans were victorious. They sealed the monsters underground with a magic spell.
Many years later…
Legends say that those who climb the mountain never return.
A young human child garbed in a blue shirt with bright purple stripes lay in a bed of golden flowers. They blinked and guarded their eyes from the faint sunlight that shone through a small hole high above. They groaned from the pain attacking their body, as they stood. The flowers had broken their fall, but not enough.
Their name was Frisk.
Frisk walked through a tall elegant doorway that seemed to be the only way out. The next room was pitch black, but Frisk remained brave and walked into the inky coffin. They stumbled forward, slowly regretting their decision.
There was no exit in sight. They were completely lost. "Hey kid, look this way."
Frisk whipped around to face the source of the voice, and what they saw nearly caused their SOUL to leap out of their body.
A short figure stood in a small circle of what was the only light in the room. They wore a hoodie that might have been blue at some point. It was so dusty and torn and stained that it was hard to tell. But, it wasn't the horrid clothes that scared Frisk… it was what was under the hood.
It was a skeleton, grinning at them with no emotion. Its teeth were yellowed and it was missing several of them. The rest of its face looked like it was in the same state of disrepair, but that wasn't the most unsettling part. It stared at Frisk, with life in its eyes.
"You must be new to the UNDERGROUND . You're probably so confused," It said, its voice confirming it to be male. He started rocking back and forth on his bare feet, which were missing several toes, while introducing himself as SANS the SKELETON.
He stopped rocking and instead held his hand out and started to coax something from the shadows. "I guess it's up to me to teach you," he said with his voice gaining a dark edge.
"You should know, in the UNDERGROUND, LOVE is shared by these… friendship rays," he said. His eye socket filled with very faint blue light, and the head of a skeletal creature appeared from the darkness. Its mouth opened…
