UNDERTALE?? IN MY 2020?? -Gender neutral so it's for everyone!- -Underfell- -most art comes from deactivated artists so I will try and credit as accurately as possible!! Many years have passed since monsters were banished underground for bringing upon a war against the humans, once they were lost to their own rage, Mount Ebott turned into a tall tale. A story about the mountain being cursed and having hidden ways of trapping people underground. They say if monsters did exist, they had no mercy in their souls. That humans were the 'good guys'. A human that fell into their world, found the tales were true about monsters existing but hopes they couldn't be as ruthless as they have been told. They wanted to believe that even these so called horrible monsters can be good if they just tried.

(mafiatale AU) monsters were freed from the underground and almost instantly, humans attacked, of course, they fought back. Your parents were killed in a shoot out, leaving you alone. You had to learn how to survive the streets. Though you never thought you would be captured by a skeleton. ((This will have multiple AU characters so be warned. Reader is a girl. May have possible smut in the future, no plans as of now))

This is a rewrite of my first successful undertale/underfell fan fiction. Yes, I know I have another story that's says it's rewritten but that's actually a sequel. I was a stupid person, I know. If you want to read the original, go here: http://my.w.tt/UiNb/jPgBpeihwD But anyway, onto the plot of the story. MC (or you) lives in a horrible household. Your mother hates your guts ever since she birthed your sister, Vanilla. Even your father took play in this. One day you decided to plan your escape, I.O.W. run away. It only took a week of planning, since your sister's birthday was coming up that week and you thought that it would be the perfect time to run away to Mt. Everett...

It is based on my dream, so I hope my brain impress you guys! :D

A long time ago, a human fell into the underground. This was the seventh and final human needed to break the barrier. The monsters had faith that the human would set them free. The human, however, killed their king, sending the kingdom into despair. The monsters turned to violence and cruelty to fill the void of hurt left by the human. When the same human happened to fall down the mountain again, the timeline is corrupted by a certain flower trying to take over the power to RESET. This allows for a flower blossom to grow on the creature with enough power to RESET. This, of course, doesn't affect the flower that can RESET, but once the human regains this power, the flowers begin to grow. With the hostile environment already in place, how can a weak human survive without RESETing multiple times? And what happens when the flowers begin to consume their body? The human will need someone to protect them, but who would take care of a human that destroyed everything they loved? Undertale--Classic story/game Credit to Toby Fox Underfell--exists shortly after a neutral route where monsters turn violent Credit to Alternate Universe community FlowerFell (Overgrowth)-- A flower grows on Frisk's body each time they RESET Credit to Siviosanei & Underfart Snas Their Tumblr: https://fleur-de-chat.tumblr.com I do not own Undertale, Underfell, or FlowerFell.
