Undertale; Despair AU《OUTDATED》

THIS IS THE OLD VERSION, YOU CAN FIND THE REWRITE ON MY PROFILE, THIS ONE IS REALLY BAD, TRUST ME. THE REWRITE ISN'T DONE BUT IT HAS QUITE A FEW PARTS RN

What if there was an anomaly in the Underground? No, not Frisk. Not Chara either. Someone else entirely. How would a few children manage to defeat them? Could they even do so? How would they free the monsters? Can they free the monsters? How will they change the monsters' fate, for the better, despite all the odds being stacked against them?

What if there's more unanswered questions within this, even after the ending?

--------------------------

THINGS TO KNOW BEFORE READING:
No fanon ships will be in this (ex. no Papyrus x anyone or Toriel x Sans. Asgore x Toriel (in the past) and Undyne x Alphys occur) . In this AU Chara is still the first ever human, just set in Frisk's time. Basically all the other characters from regular are there, just some events haven't taken place yet. Chara fell in 2005, Frisk fell in 2015. No other humans fell in between. THIS IS NOT AN X READER IF THATS WHAT YOU ARE LOOKING FOR. ITS A FUN STORY WITH A HINT OF SADNESS. I WILL NOT EVER WRITE AN X READER FOR UT OR DR, NOR MAINLY SHIP STORIES

⚠THIS IS ALL AN ALTERNATIVE UNIVERSE. NOTHING IS CANON. NOT EVERYTHING IS DIFFERENT. PLEASE DON'T SAY "Chara fell in 201X not 2005" OR ANYTHING, THIS IS AN AU. NOT A CANON SEQUEL. THANK YOU⚠

Credits:
"UNDERTALE" created by Toby Fox and Temmie Chang. Inspiration for some parts from "Undertale the Musical" created by 'Man on the Internet'. Some other parts are inspired by or in reference to "The Better Times" and "From War to Science" series (Authors of both on my following, "The Better Times" by ANinnyMouse42, "From War to Science" by Emotistic-optimistic. All the stories involved are on one of my reading lists too. If you haven't read them READ THEM AT THIS VERY MOMENT)

This an original idea (I think), although there are some credits for inspiration above this

Anyway, my rant is over now
