Your pov

You were a part of the star sanses for a while now. You ddint really join the battles, you were just there to heal them after their battles. One day, you noticed how lonely you were in the doodle spehere while waiting  for them to come back. You also didn't have anything to do and you were starting to get worried. Their battles lasted longer and they cone back more injured than before. You wanted to join the battles so that you know their safe but they didn't let you. They wanted you to be safe. You huffed. "Oh come on inky! Please!" You gave him pleading eyes, making your ears flattened as your tail waved side to side. He blushed rainbow. "Ehhh... Sorry (y/n) but my answer is still no. You might get injured and your way too fragile." You pouted. Blue went to you and hugged you. "PLEASE (Y/N), WE JUST WANT THE BEST FOR YOU AND KNOWING THEM, THEY WILL MOST LIKELY TARGET YOU AND USE YOU TO THREATEN US." Dream looked at you sadly. "Please understand (y/n), we only want the best for you." You sighed, ears still drooped down. "Alright..." Blue let you go as ink pet you. You purred a little, making the skeleton trio blush. "Don't worry, after this mission, we'll buy you nice cream and we'll take you out to grillby's. " your ears perked up as your eyes sparkled. "Really?" They nodded. You smiled sweetly. Dream looked at ink. "Come on ink, we must go now." Ink sighed and opened a portal. You waved then goodbye as they jumped in the portal. You sighed and sat down, relaxing. Then, one of your ears raised up. You felt a presence behind you. You looked behind you but before you can see them, you got knocked out.

"Heh. They'll do anything just for you? Pathetic, you can't even defend yourself." Your eyes opened and you saw that you were in a cell. You saw a goopy skeleton with tentacles outside the cell. You smiled at them. "Hello! I'm (y/n)! Ummm... Can you please help me out here?" He then laughed darkly. You shivered, a bit scared. "Now I'm just wondering why do they waste their time with someone as useless as you. Your more ignorant and naive than they can ever be!" You then heard a few clangs and blasts. The skeleton looked to his side as his smirk widened. He looked at you. "Well then, they're finally here. Come now 'kitty'." He chuckled as he opened the cell door. His tentacle grabbed your ankle without warning as he dragged you, not even caring if you bump your head. You tried to remove his tentacle as you reached a big room with different skeletons in it, fighting. You recognized ink, blue and dream in the crowd. "Let me go!!!" You screamed as you were lifted up. A tentacle was placed on your neck as the tentacle on your ankle went away. You were getting strangled. You can't breathe! You saw ink, blue and dream look at you in worry. "(Y/n)! Nightmare! Let her go!!!" "One move and she gets it." They were frozen as the nightmare's smirk widened. You used your hands to try and pry off his tentacle off your neck. Strangely enough, you can't use your magic. Must be disabled. "Now, let us take complete control of this universe and maybe I'll let her go." "No!!!" The tentacle tightens, chocking you more. Your hands desperately clawed at it but it did not effect. You kicked your legs as your tail hit nightmare. He got annoyed and pulled your tail. "Stupid thing... Stop flailing it around or I'll pull it off!" You tried to make it stop. Clue word, tried. Of course, your tail always corresponds to your emotions. You were panicked as heck so it didn't stop. Nightmare, annoyed, pulled at it with no mercy. A scream left your mouth as he pulled it off, blood pouring at where it was once was. Tears fell down your cheeks as you cried, feeling immense pain. "(Y/N)!" Blue was about to run to you but ink stopped him. "Blue, don't, she'll be hurt more." You just cried as blood fell trickled down your leg. A red puddle was under you. "W-why...?" You barely asked. You looked at nightmare. "W-why are y-you... D-doing thi-is?" Nightmare looked at you. You didn't know that his smirk can widen even more until now. "Why?" He chuckled. "Why?!" He then burst out laughing, his laugh mkaing the three skeletons and you shiver. He looked at you, a little amused. "Don't you get it? They hated me, despised me. They ruined my life! I can only watch as they ruined it while they were having the time of their life! They were happy! Satisfied! Those selfish beings don't deserve to he happy when they just ruined my life! They should know how it feels like! How it feels like to feel lonely! Abandoned! Hated! To be at someone's mercy even when you didn't even do anything to them! I didn't even ask to be negativity's guardian. To be evil's guardian. They hurt me for doing my job. They hurt me for being forced to do something I didn't even want! Then, I saw my brother, dream. He was just getting all the attention just because everybody thinks that he's better than me! Just because they see me as the 'bad guy' while everyone sees him as the 'hero'. I just want revenge. I want to see their petrified faces as I rule over them! As I torture them like they tortured me! They should know that every action has a price..." He ended it with a dark but sad chuckle. It was silent for a while. Nobody moved as his grip loosened, making you able to breathe a little. You smiled at him. "But do you have to do this? You can always tell them. I'm sure that they'll understand and-" he threw you to the ground, taking you by surprise. "You idiot! Do you really think kindness is the only answer to everything?! That rainbows and ponies will be everywhere?! Heh. You really are dumb. Besides, why am I telling you this? Your going to die anyway." The three skeletons tried to run to you. "W-wait-!" Their desperate pleas weren't worth it. Nightmare stabbed your abdomen. They could only watch in horror as your life flashed right before everyone's eyes. Nightmare laughed at your bleeding body as you looked at him with shock. The three skeletons got through nightmare's crew. Ink distracted nightmare as dream and blue escaped with you. Ink came to the doodle sphere shortly after. Dream set you on the bed ink summoned. Blue tried to heal you but he can't. Dream held onto you desperately. "No no no no no no no no!!! (Y/n)!!! Please!!! Stay awake for us!!!" Ink just kneeled beside you, crying. He held onto your hand and brushed his thumb against it. "Y-you can't give up now... Please, stay alive for us..." You just looked at them weakly, tears streaming down your face. "I-ink...? D-dream...? Blue...? W-whats going on...? W-why are you... C-crying...? W-why does it... Hurt s-so much...? I-i don't w-want this..." Blueberry gave you a forced smile. "(Y-y/n)... Please... Whatever you do, stay awake for us alright...?" He forced out his words through the tears as he kept trying to heal you. The other two helped as much as they can. Your eyes were drooping down. "I-i... Can't... I feel so t-tired....." "No! (Y/n)! Hang on! You'll be alright! Please!" Dream exclaimed. "Stay awake (y/n)! We promised you some nice cream right?" Ink added. You smiled at fhem, not really understanding. "I-i'll just... Eat it.... W-when I w-wake up..." The three skeletons could do nothing but cry. "I love you..." They chorused. Your smile widned. "I... L-love you all t-too..." Everyone fell silent as your breathed out your last breath.

Couldn't really think of a plot with a fluff ending soooo... Yep, back with angst, my favorite. It's short, yeah I know. Also, I don't really know if that's the real reason why nightmare is like that. Of course he's like that because of the apples and jealousy but I might be wrong. Anyways, boi!!!
