TMNT one-shots!

Klunk

*Kind of a cross between 2012 and 2003, Also be warned of character death*

Mikey gripped his controller like a madman as he worked his fingers over it, tongue out in concentration. He was currently in the lead of his racing game, and he wasn’t planning on getting beat. 
“Mikey, get off the back of the couch!” Leo barked, nearly startling Mikey out of his shell.
Mikey made an incoherent noise as he rolled onto the couch.
“Leo! You made me lose!” He threw his controller to the side, falling dramatically to the floor.
“I’m booored!”
“Shuddup Mikey, I’m tryin ta read here!” Raph scowled.
“I hate being bored.”
A sigh sounded by the garage entrance. “Finally, I finished fixing up the battle shell.”
“Hey Don,” Leo greeted.
“Doooniee!” Mikey shot up. “Can I drive it? Can I drive it?”
“No. Absolutely not.”
“Awww… Please, Donnie, please! I’ll be super-duper careful, I promise!”
Leo glanced between his two youngest brothers, pursing his lips in amusement. 
“Mikey, I said no.”
Mikey pouted. “Pwease?”
Donnie groaned, sliding a hand down his face.
“I promise nothing will happen, I-”
“Alright! Alright!”
Raph chuckled from his corner, looking up from his comic book.
“Ya betta kiss all yer hard work g’ bye Don.” 
Mikey was too excited to rebut Raph’s comment and Donnie just ignored him. With a deep reluctant sigh, Donnie chucked the keys at Mikey. 
“Woah! Chill D, nothings gonna happen,” Mikey chirped, flashing him a grin before skipping away. 
Donnie fell to the couch, head in hands.
“You ain’t gonna supervise ‘im?”
Donnie lifted his head to look at Raph. “No, I’ve accepted my fate. He’s the one who’ll have to clean his own mess.”
Leo shook his head. “Poor Battle Shell…”
“Poor me! I’m the one who’ll have to rebuild it all over again!”
Raph snorted. “Mikey’s right, you gotta chill Don.”

*Meanwhile in the garage*

“Aw yeah!” Mikey whooped, tossing up the Battle Shell keys before catching them again.
He jumped inside and started her up, smiling wildly to himself.
“Ok, easy does it-” Mikey slowly pushed down on the gas and the vehicle lurched forward before he stopped it again.
“See, you’ve got it, no sweat!”
He started forward again, with more confidence this time. The tires crunched over the loose gravel that stretched out across the garage floor. It was satisfying to feel so in control for Mikey. 
“This is great-” A horrific shriek sounded from somewhere below, making Mikey yelp.
He slammed the brakes and scrambled out of the Battle Shell. He began to tremble as he got down on his hands and knees to look underneath the armored van. He screamed before he could even bring a hand to his mouth. There, on the cracked cement, lay a ball of orange fur surrounded by blood, spewed out across the pavement like the red of a sunset unrolling across the sky. Another scream escaped his lips, coursing roughly through his throat, leaving it raw and dry. He screamed and screamed until his lungs couldn’t take it and his lips were sticky from wiping his tongue across them. He reached out for his beloved cat but his arm seemed to have a mind of its own. 
“K- Klunk?”
There was no movement that indicated life, so he called to her again, just in case she hadn’t heard.
“Oh God! I should have listened to Donnie! I should have listened!” He wailed.
“Klunk, please wake up, please wake up!” He stretched his hand out again, and this time it came into contact with the stiff cold fur that had once been so warm. 
“Wake up! Come on Klunk! You’re so cold, let’s go inside and I’ll wrap you up in a real fuzzy blanket and I’ll feed you some tuna, you’re favorite!” He paused, sniffling.
“Then we’ll go to bed and...”
Silence consumed the young turtle. His eyes began to water and he wiped them furiously, angry at himself because there was no one else to be angry at, no one else to blame. This was his fault. All his fault. 
“Klunk…”
Mikey grit his teeth together, and in a fluid motion, he picked up his cat from the floor and held her to his chest, unconcerned by the sticky substance that painted his plastron and hands in a dark crimson.
His vision blurred with stinging tears as he shuddered out a painful sob.
After what seemed like an eternity, Mikey lifted himself from the floor, legs quaking like jello. He set Klunk down on the floor again, no longer able to see her like that. 
His steps we're sluggish and each one filled to the brim with remorse. He entered the lair in complete silence. He was scared of his brother's reaction, but he was so out of it that he didn’t have time to think of a good lie. 
"Mikey?" Leo was the first to notice him, as he looked over from the tv.
Leo's face froze for a second before he gasped, attaining the attention of both Donatello and Raphael. 
"Mikey? Is that blood? Are you hurt, what happened?"
Raph, despite the panicked look in his eyes, smirked. "Told ya he'd get inta trouble."
Leo shot him a glare as Donnie stood up and made his way to Mikey.
"Mikey?" He asked gently, finding his unusual silence unnerving.
Mikey peered up to meet his eyes and Donnie's breath caught in his throat. 
"Mikey, are you crying?"
Mikey wiped at the stray tears, making a pathetic attempt to control his inner turmoil. 
“N- no…”
“Are you hurt?” 
“I- no.”
“Mikey-”
“Then where’d all that damn blood come from shell-for-brains?” Raph questioned before his face darkened. “You didn’t kill anyone did you?”
He surely had been joking, but that assumption hit too close to home.
A long strangled cry left Mikey's mouth and his legs finally betrayed him. Donnie caught him by the elbows, lowering him to the floor, his face scrunched as if he were deep in thought. 
Mikey would’ve laughed at Raph’s startled face, but his heart was in too much pain, and even if it wasn’t, his sobs surely would’ve drowned out his laughter. 
“Woah, woah, I was jus’ jokin’ Mike.”
Mikey shook his head, unable to form any words, which was frightening since Mikey always had something to say. 
His three brothers stared at him like he was a museum exhibit, unsure of what to do. 
After a moment of hesitation, the leader grabbed Mikey by the shoulders and pulled him into a hug. 
"Klunk…" Mikey finally choked out, his voice muffled into Leo's shoulder.
"Klunk, what about Klunk?" Donnie questioned.
Mikey pulled away from Leo, with a whimper. "Donnie, you were right! I should have never driven that stupid car!"
Leo exchanged glances with Donnie, and Raph took the chance to step in.
"What happened to your cat?" 
Mikey wailed like a child. "I hit her!"
Donnie's eyes widened. "That could be serious, I have to check on her-" 
Donnie went to stand up but Mikey caught his arm, yanking him back down. 
"Mikey, let go!"
“What are ya doin? She’s obviously hurt!” Raph motioned to the crimson liquid on his little brother.
"Donnie- She's dead!"
The room was engulfed in silence but it only lasted a few seconds before the youngest had once again dissolved into sobs. His frame shook with their intensity and it took every fiber of his being not to scream like before.
“Mikey- Are you sure she’s dead? Maybe she just looked dead from under the car?”
A strange pang of anger twisted in Mikey’s gut. He knew he shouldn’t take his anger out on his brother, but he couldn’t help it. Blaming someone else was so much easier than blaming himself right now. 
“I held her donnie!” He screamed, hands quivering. He took a breath, lowering his voice.
“I tried to wake her up, but she was cold and hard and-”
Leo bit his lip. “Oh Mikey…”
“I don’t know what to do! I don’t want her to be dead! I- It was my fault!”
Raph kneeled down to Mikey’s level, frowning deeply. “Mikey I’m sorry…”
He opened his arms with lack of anything better to do.
Without question, Mikey leapt into his arms, hiding his face in Raph’s chest.
Out of all his brothers, Mikey knew that Raph understood what it was like to lose a pet. 
“Raph, what do I do?” He hiccuped.
Raph held his shaking brother close, rubbing circles on his shell in a comforting manner. 
“I don’t know Mikey, I don’t know…”
“I killed Klunk!”
“I know Mikey, but you didn’t do it on purpose, she knew that.”
“That doesn’t change the fact that she’s dead!”
Raph sighed. “There’s nothing you can do Mikey.”
Leo jabbed Raph in the side, making him yelp and glare over at him. 
“You’re not helping Raph!”
“Oh ya, what do you know ‘bout losing a pet?”
Leo released a breath, lowering his eyes. 
“Mikey, listen to me. Klunk loved you to the very end, don’t doubt that, she would never blame you for what happened.” 
Donnie nodded, “It was an accident, and the best thing you can do now is help her move on…”
“Move on?” 
“We should have a funeral.”
Raph rubbed Mikey’s head. “Where do you wanna bury her?”
Mikey shrugged, not feeling like talking.
“Well, there’s not many places in New York, but we could go to the farmhouse, how does that sound Mikey?”
Mikey stayed silent for a few seconds before nodding slowly. “Yeah, I think she’d like that.”
Leo gave him a sad smile. “It’s going to be ok Mikey…”
“Yeah…”

I might do a part 2, let me know if I should.
