    Summary

    With each death the darkness grows, consuming and twisting a lost soul that is torn from betrayal.
    Why does this seem so familiar? These dreams feel so real...
    Are they dreams or perhaps they are memories of another life? Another timeline?
    Two voices call out to the lost soul... One offers help, all they want is to be friends.
    The other, a weaken whisper that longs to be heard. Everyone lies, betrayal runs deep.
    Who to trust when both voices lie?

    Another soul tired but refuses to give up, for he knows what will happen if he does.

    "i wasn't ready for this responsibility... but darling... you didn't give me much a choice..."
    He says as he raises his bony hand, a faint purple aura around it.

    Summary

    Happy 3rd Anniversary, Undertale!

    After over 2000 resets, and watching his little brother die yet again, Sans finally snaps. His new choices lead to the barrier breaking and him assuming control of monsters. However, by absorbing the Red Soul and Chara's hatred, Sans becomes a ruthless dictator after almost single-handedly winning the war against humanity.
    Over 50 years pass, and Sans is still in command, respected and feared by monsters and humans. Humans have become slaves - treated well so long as they obey - and a new species has been born. They have been officially called Mongrels, and they are the offspring of human mages and monsters. All mages are eliminated, and Mongrels are sent to orphanages to learn to live in society with low level jobs to keep them under control.
    However, one day Sans stumbles upon a group of monster teens beating up a female mongrel they kidnapped specifically to abuse before handing over to the Royal Guard as a 'runaway' and immediately takes the abused girl in, much to the shock and dismay of the rest of the world. For someone who has been so ruthless, it makes no sense. But the world will soon realize that the mongrel, Raina is the key to Sans returning to his true self.

    Summary

    After his timeline was destroyed along with almost everyone in it, the Sans who would come to be known as ‘Blue’ had an epiphany.

    Everything sucked. Like, all the time.

    It was not, perhaps, a new discovery, but it was the first time he had admitted it to himself. He had always tried to keep a positive attitude in life, even if his recent circumstances had put a sizable dent in his motivation.

    But still, he wouldn’t give up! As long as there were still monsters out there who could use his help, Blue would never give up.

    And so, stuck traveling the multiverse with a child and stuffed toy that were doing their best to kill him at every turn, Blue attempted to help prevent other universes from meeting the same fate as his - and perhaps make some new friends along the way!

    After all, just because life is hell doesn’t mean that he shouldn’t be cheerful about it!

    (in which Underswap Sans survives a no-mercy timeline unlike any other, and ends up losing both his home and his ability to Be Chill™.)

    Summary

    "And they'd never...ruin our plans they way you have. The human souls we'd use to break the barrier...they were all absorbed. All held by monsters you killed. And the souls are all gone now. Any chance of escaping is gone." Flowey cocked an eyebrow at them. "Whoever or whatever you are, you're not them. You're not my best friend."

    "You want to fight?" The flower laughed once more. "Alright. I'll take your soul, and with your determination, I'll reset and free monsterkind myself!"

    As the human drew closer, the flower grew bigger. It's stem grew, and leaves and vines popped out of the ground. This wasn't just some tiny weed. This was a nuisance.

    Summary

    When you fell into the Underground, you were only 13.

    Found by Toriel, you didn't hesitate to go with her. You lived with the goat monster who had taken you in and, though you knew that there was more to be explored, you never wished to leave the place you resided in. For 8 years, everything was perfect. You finally found a place that you called home.

    Then someone else fell down - Frisk.

    When they fell down, you watched as the world around you seemingly became a game. It started with the odd sense of deja vu that seemed to become a regular occurrence in your life. Once you watched the child murder Toriel in cold blood for the first time only for the loving monster to reappear with no recollection of what had happened, you knew something was wrong.

    You began to lock yourself in your room whenever everything restarted and, once the child left, you would reappear to discover what had happened in your absence. After this constant pattern, it seemed as if Frisk had finally forgotten your existence in the flood of resets and timelines.

    Time forgot your existence and that was fine with you.

    However, everything changed once again when you were the one to answer the knocking on the old ruin doors.

    Summary

    History says, Don't hope
    On this side of the grave,
    But then, once in a lifetime
    The longed-for tidal wave
    Of justice can rise up
    And hope and history rhyme.

    --

    Undyne emerges victorious from her battle with the murderous human child, successfully absorbing their soul and putting an end to both their violence and the War.

    At least, it'd be nice if it was all that simple. Things are about to get a lot more complicated.

    Summary

    Alphys had only a handful of happiness when Frisk fell down and destroyed her universe. In her final moments, she stands at the abyss and remembers the many times she was drawn here, the reasons why, and why she was always drawn back. Each time, she had reason to turn away.

    Now, all of those reasons were dead, and she is alone.

    In a world where her heart is smashed to pieces, she at least has this one common refuge. Is it no wonder she makes it her last?

    Pure depression. No happy ending. Everyone dies/ No Mercy ending.
