ROTTMNT x Reader Oneshots

-Yandere!Donnie x Reader-

[Just to start off the actual book. I'm sorry, but I'm going through a ROTTMNT phrase right now. Also, im sorry is Donnie is a bit out of character. Lastly, slight gore warning]

Donnie's POV
"Y/N!" I yelled out as I lifted my goggles. I waited a few seconds for her to come. "Y/N?" I repeated, getting up to search for her.

I begin to panic slightly. "Y-Y/N?!"
"Yea?" A sweet, innocent voice answered. I turned around to see my Y/N. I went to hug her, but she gently pushed me away. "Careful, i have a tray of cookies! I don't want to drop them..." She stated. My older brother, Raph, came in at grabbed a cookie. He took a bite and smiled. "These are the best cookies ever!" He announced, giving Y/N a quick side hug.

I froze. He Just Touched- No, HUGGED My Y/N.

"Uhhhhh, D?" Raph said, waving his hand in front of my face. I then zombie-walked to my lab. "What's with Donnie?" Leo asked as saw Donnie's walking style. Y/N shrugged. "He just kinda froze" Leo then saw the cookies. "Ooo, cookies!" He said, taking one. As if on cue, Mikey came out of nowhere and took the majority of the cookies.

~Later that Night~

I quietly crept into Raph's room, with a knife in hand. "Shouldn't have touched Y/N. I'd really hate to do this, but there's no other way to assure that you'll never touch her again..." I whispered to myself. I then began stabbing Raph multiple times. Soon, after I was sure he was dead, i dragged him out of the sewers and took him to the dumpster.

~The Next Day~

Y/N's POV

I paced around nervously. Mikey saw and walked over. "What's wrong, (cute nickname)?" He asked as I looked at him. I grabbed his shoulders and shook him. "RAPH IS MISSING!!" I shouted. "What a shame..." Donnie said, cleaning a knife. "Oh, hi Donnie!" Mikey said, waving and smiling.

"Donnie, do you know where Raph is?" I asked, but he shook his head. "I'm afraid not, my dear Y/N-" he said.

Mikey soon walked over to Y/N and patted her back, don't worry (cute nickname), we'll find Raph! Right Donnie?" He said, looking over at him. Donnie was frozen again. "Donnie? Donnie! DONATELLO?!?!" Mikey said. "Maybe his song will snap him out of it-"

"Loom 16, take Corridor B. Down the stairs, past the Ibis Tapestry. Sliding bookcase after bookcase, show the way to the hall. Up the pole, to the hole in the waterfall! Donatello! With the book in his hand, saves the day and proves to everyone he's the man!"
Mikey rapped. I looked at the orange turtle in confusion.
"How did you get that song? You weren't there!" I said. "He was singing it in the shower once" Mikey answered. We both turned to look at Donnie, but he had disappeared.

When it was nighttime, Donnie had repeated the process he did to Raph on Mikey. After he finished, he threw the second turtle away in the dumpster. "Just one more to go...." Donnie muttered, smiling creepily afterwards.
