Crossing the Limit (Undertale) by Espeon804

(Alternate Ending added!) "If you solve your problems with kindness instead of violence, then everyone wins! Violence isn't necessary! It only hurts people! It can sometimes make the conflict worse!" ----------------------------------------------------------------- He's kind. He's gentle. He is so forgiving. He always welcomed a stranger with open arms. He wouldn't hurt a fly. It's disgusting. But that is why Papyrus never fails to catch Flowey's interest. So, Flowey decides to cross a line. A line that is the border between forgiveness and retaliation. Rated T for violence and some language.

Underfell Skelebros backstory! Technically a prequel to my story, "A Three Way SWAP," but you don't need to read that to understand what's going on. Takes place in the world of Underfell. We learn what happened to Papyrus to make him so cold and distant in Underfell. WARNING: MILDLY VIOLENT AND MENTIONS SUICIDE. GETS A LITTLE DARK. YOU'VE BEEN WARNED.

Chara has one objective: RESET back to when they themself fell, and save Asriel from his demise. With all the Genocide Runs the now-free Frisk goes on for them, they're able to amass a big enough collection of SOULs to do exactly that. The only problem is, Asriel remembers everything that happened when he was Flowey. And he isn't too happy about it... In this new timeline, Kelsa, the SOUL of Bravery, falls into the Underground shortly after Frisk. Determined to save her only friend, Kel teams up with a mysterious flower with a face to find them and rescue them from Asriel's notorious freezing chambers. Betrayed by many, and uncertain who to trust, Kel finds herself in the midst of an iron-fist dictatorship, fighting to restore the Underground to the peaceful place it used to be. But... all is not as it seems, and there may be things about Frisk that Kel will wish she'd never discovered... Cover art by yours truly :3 This story takes place after the events of Underhappened. You may wish to read that first if you haven't already :D

Protect One Another - US!Papyrus x Reader by robin-rights

Trauma is a powerful thing, and not something to be taken lightly. Especially if your "best friend" is the cause of it. But friendship, understanding, and love, are also powerful things. They can save someone from the depths of despair. And those people that pull us from terror are often the ones we fall in love with. Platonically... and sometimes, romantically. *** Undertale and all original characters belong to Toby Fox, Underswap and its characters belong to Popcorn Pr1nce (inactive tumblr now).

Fight or Mercy | Underfell x Abused! Reader by YuniccAfton

[2nd book] ((COMPLETED)) {Undertale AU - Underfell} [WARNING:ENDING AND PLOT IS VERY CRINGEY] "Long ago, two races ruled the earth, the Humans and the Monsters. One day, war broke between the two races. Many have fallen to serve their kind. Years later, the humans were victorious. With their magic, seven of their strongest wizards sealed all the monsters underground with a magical barrier. Only a human soul could pass. Mt. Ebott 201X, they say those daring enough to climb up the mountain.... never return. " "Leave them, Y/N! Run! " ___________________________________________ I'm a Undertale addict. I freaking love the story line and characters! One of my favorite AUs is Underfell so I'm finally making an X reader. Also, if there are wrong spelling or grammar, please tell me. I'm using GoKeyboard. Enjoy my Crappy 2nd book!

Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great. Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 24th May 2021 Finished: 29th December 2021 A full 7 months of great fun with this book!
