Work in Progress of Undertale of Serena Walken
I wanted to make a place for the Undertales that I am working on that aren't complete or retired. You can still read them, but know that they are incomplete right now. Check last update dates to see which ones I am the most active in right now.

Summary
Frisk is imprisoned in an unescapable hell above the surface with her children and her only friend in the world, Flowey. She should be there for the rest of her life. That is until the day the monsters learned the truth about the 'Pacifist Child'. Sans does his best to get her out of the predicament, but some things that break just can't be fixed: Like timelines.
This version of the story is exclusive to ao3 and my site. If you ever read the other version and thought 'what if . . .?' at the ending? You might actually like this one:)

Summary
When Papyrus' daughters want something read to them that has princesses in it, Sans chooses the lazy way instead of coming up with a story. He types princess in the timeline machine and straight reads off a Princess Frisk adventure. After a couple of nights, Papyrus leaves and Sans is in charge of the girls. When he reaches the end of the princess adventure, he knows where Papyrus is at.
He also knows that their timeline is about to be erased, if he doesn't find his own version of Princess Frisk.

Summary
Before World 36 signed off, a world was just beginning to sign on. Unallowed to leave to different timelines, a new Gaster has come back with the help of a desperate Sans as Frisk and Asriel create more torment in his life with their new human groupie, a boy named Kevin. Understanding that certain things still flow through, Gaster uses Undyne and mutiny to bring the monsters closer to winning the war against not the humans (no threat), but all monster kingdoms themselves. (World 10)

Summary
Hopeless and in despair, Sans never thought he could escape the resets and continues caused by FRISK that tormented his life. But, when he thinks the kid is possessed and stops FRISK once and for all he finds out ... that he never really knew anything after all.
No more resets. No more saves. No more hiding. Life will never be the same for the Underground.
Souls and Science can be an unforgiving bitch, and Sans will have to work with the Frisks to leave the Underground, find their ways through new enemies, new territories (and old memories) to stop a new threat they never saw coming: A Flower with a Chance.*This is an alternative story to the original Conduit Tale, exclusive to ao3 and my site.

Summary
When mankind slaughtered all of the monsters, only one survived. With the power of a spell the monsters had used more than once to keep going, Sans is the last monster alive to cast it. Now, four years later, he has located the elusive devil/angel 'Frisk', and his journey to reestablish the kingdom has begun.
Except, this time, the kingdom would never be the same.
(Usually my Undertale's focus monstly on Sans and Frisk, but this one will actually feature multiple main characters with their own arches.)
