Love over hate (inkmare/nightink) by trixielovesick

When nightmare is told he isn't a king, he must marry to become one. He doesn't care about who, he just wants the name. Will he find love? Welp that changes when he finds out about one of dream's love potions......

Color took Killer and gave him his emotions, everything was fine at first but then he got bored and to think of it he missed killing other's, would he spend his day's killing bugs or would he escape. The bad guy Sanses were REALLY sad. Don't get me started on Nightmare's mental state.... Edit: I've decided to re-write this story complete so there'll be some big changes

Nightmare, who has been dead for the last century, stumbles across a dying Sans in a destroyed au and takes him under his wing. Er, tentacles. From there, they start a band of rejects to get revenge on his brother. Sadly, said brother has other plans for them. That wont stop the shakily made team from bonding and having fun though! (AU where Killer is the leader of the 'Bad Sanses'. I own pretty much none of the characters)

Feelings Are Overrated ~Killer X Nightmare~ by OreoCookie1129

It's Not Possible ( Nightmare x Killer ) by jesus_davito13

It's almost the end of highschool for Killer, an 19 year old student at a human and monster school on the surface. Killer isn't ready to leave the highschool yet as he's afraid he can no longer see his English teacher again. So he decides to spend each and every day with his English teacher as mush as he can. But how will others think of this close relationship with the high school English teacher? Update in 2023: this is a cringe, wacky ass story I wrote in the beginning of 2021 and I refuse to even try to patch it up or continue it

Three Days [KILLERMARE] by Shattered_Simp

After an assassination attempt to kill Nightmare, his life was saved by a complete stranger. In exchange for this stranger's good deed, Nightmare would repay them many years later. Little did the guardian of negativity know that this deal would be the start and the end of many relationships. The guardian's bad past with romance will have to be set aside as Nightmare is only given three days to find "love", or his entire life could be ruined. AN OFFICIAL REWRITE OF THE OG!!

He looked me dead in the eyes, "lay down and rest." I felt fine though. Why do I have to rest? His tentacles wrapped around me, moving me to his bed, "Rest." He said as his tentacles slowly let go of me. Jeez... I guess I'll rest for a bit.

Blue decides to leave the good side and join Nightmare's group as he is sick and tired of helping others at the cost of his own. What happens? Trigger Warning: Abuse Rape memories Neglect Kidnapped Suicidal thoughts Mental health Mental illness recovery Lemon 🍋
