What if Kari's poison was more deadly than anything

and what if she when for the smallest first

TW: blood

The wind howled through the city of New York as Raph and Mikey stood on the rooftop, surveying the city below.

It was supposed to be a simple patrol.

Go out, stop some muggings, go home eat some pizza,

Mikey shifts his weight from foot to foot, his nunchaku swinging gently at his side.

"Mikey, I think someones watching us," Raph mutters, reaching for his sais.

"You sure?" Mikey asks.

Suddenly, Kari appears out of the shadows, a malicious grin spreading across her face. "I've been waiting for you, turtles. I have a score to settle with ," she hisses her snake-like tongue flicking in and out.

Mikey and Raph tense up, ready to defend themselves. They instinctively get into fighting stances, their weapons at the ready.

"What do you want, Kari?" Raph demands, his expression furious.

"I want Leo to suffer, that's what I want!" she hisses, her fangs bared. "And what better way than to slowly kill his brothers... one...by...one."

With a hiss, Kari's body contorts, stretching and twisting as her arms lengthen and her hands become snake heads

she snarls, lunging forward at Mikey with her snake-arms extended.

Mikey leaps back, narrowly avoiding the attack.

He swings his nunchucks at one of the snake heads, but it misses and thumps against the ground.

Raph charged forward, aiming a powerful roundhouse kick at another snake head.

The impact sends Kari stumbling back, but she quickly regains her balance.

Kari jumps at the two turtles, her snake-like arms stretching and moving with incredible speed.

Raph, anticipating the attack, leaps forward and delivers a powerful kick to Kari's midsection.

The force of the blow sends her flying through the air and crashing down onto the concrete below.

She hits the ground hard, causing her to go unconscious

Mikey and Raph jump down after her.

Mikey kneeling down beside her, making sure she's really out, while Raph whips out his t-phone and hastily dials Leonardo's number.

"Hey Leo we got Kari- yea were fine fearless…. How is she? Unconscious."

Mikey watches as Raph paces as he talks to Leo.

A shiver ran down his spine as he felt something touched his ankle.

Mikey glanced down

And screamed

Before Raph can hang up, he hears Mikey let out a scream.

He turns around to see Kari, her snake-like arms wrapped around Mikey's ankle, sinking her fangs deep into his green skin.

Mikey Kicks Kari in the face causing her to let go as he stumbles backward, clutching his wounded leg.

"Shit!" Raph curses, quickly dropping the phone and running over to Mikey as Kari slithers away and disappears

"Raph, I... I don't feel so good," Mikey manages to get out between ragged breaths, his eyes already looking unfocused.

Raph's face pales in fear as he realizes what's happening. "No, Mikey... Stay with me, buddy..."

Raph says as he shakes his brother, trying to keep him conscious.

A trail of blood drips out of Mikey's nose as Raph picks his phone up from off the ground, his call with Leo still active.

"LEO! Get Donnie and get over here! NOW!" He screams into the t-phone.

His eyes are wild with fear as he looks at Mikey, who's struggling to stay conscious.

"Mikey... Mikey, hang on buddy... Help is on the way... I promise..." He says, laying his brother in his lap and wiping the blood from his nose.

Mikey's head lolls to the side, his eyes slightly glazed as he tries to stay conscious.

He can hear Raph talking, but he doesn't really understand what he's saying.

All he can think about is the pain in his leg and the growing darkness at the edges of his vision.

"Raph...hurts..." Mikey whispers through gritted teeth, his eyes starting to close.

The world is fading into black.

He tries to reach out to Raph, but his limbs are leaden and unresponsive.

His heart pounds in his chest, fear and panic rising as he realizes that he's losing the fight to stay conscious.

Raph shakes Mikey violently, tears starting down his face.

"No Mikey! You can't leave me! Hang on, damn it! Don't you dare leave me!" He begs, as he hears the Shellrazor approaching in the distance.

"I'm gonna get you help, Mikey... I promise...You hear that, Mikey? You're gonna be okay... Just hold on..." He pleads, kissing his brother on the forehead.

Suddenly, there's a commotion as Donatello comes barreling out of the Shellrazor, skidding to a halt beside them.

"Raph, what's going on?!" he shouts, his eyes darting between the two of them.

He drops to his knees next to Mikey, feeling for a pulse and checking his breathing. "Mikey, buddy, can you hear me?" he asks, concern etched on his face.

Mikey feels a hand on his neck, and he tries to focus on Donnie's face, but it's still fuzzy.

He can hear him, though, and that gives him a little bit of hope.

"D... Donnie... hurt..." he whispers, his voice barely audible.

Raph looks to Donnie, eyes filled with a mix of fear and anger.

"She bit him! The snake-bitch bit him!"

"I know Raph I know!" Donnie snaps but Raph as already turned his attention back to Mikey

"Mikey, buddy, you're going to be okay. We're here for you, we're going to get you fixed up and make you better. You hear me?" Raph coos

"Raph, get Mikey to the Shellrazor," Donnie commands. "We need to get him inside and get him stabilized."

Raph nods and quickly picks Mikey up, cradling him in his powerful arms.

Donnie and Raph sprint back toward the Shellrazor as they enter; they see Leo in the driver's seat, concern written all over his face.

Raph climbs in with Mikey in his arms, Donnie handing the phone off to Leo. "Call Master Spliter, Leo. Tell him to get my lab set up!" he shouts, before turning his attention back to Mikey.

Raph lays Mikey down on the bench seat in the back.

Quickly Donnie removes his belt, fashioning a makeshift tourniquet around Mikey's wounded leg.

Mikey grits his teeth against the pain as Donnie tightens the tourniquet. He feels like he's going to pass out again.

"Hang in there, Mikey... just hang in there..." Donnie whispers looking around in the Shellrazor for anything he could use to slow the poison down.

Mikey's breathing is shallow and ragged, but he's trying to stay conscious.

Looking up at Raph and Donnie, a small smile tugs at the corner of his mouth.

"... you guy's lo'k f'nny..." Mikey mumbles, his voice barely audible. He can feel his eyelids growing heavy and his body beginning to go numb.

"Y'you d'don't have to worry... about me... I'm...k..." His voice trails off as Mikey loses the battle to stay conscious, a contented smile on his face.

"No... Mikey..." Raph whispers, tears streaming down his face as he sees his brother's chest stop moving.

Donnie's eyes widened in horror and disbelief.

Mikey's limp body lies there.

"No..." Raph chokes out, his voice cracking. "No... this can't be happening..."

"Raph... I'm so sorry..." Donnie whispers, reaching out to try and comfort his older brother.

But Raph shrugs him off, unable to bear the touch.

Raph looks down at Mikey, tears streaming down his face, and clenches his fists.

"She... she did this to him..." he whispers. "She killed him..."

"Raph-"

"KARI KILLED OUR BABY BROTHER!" Raph screams at the top of his lungs, his voice echoing through the Shellrazor.

"SHE DID THIS! SHE TOOK HIM FROM US!"

Raph punches the metal floor.

"I'M GOING TO KILL HER! I'M GOING TO MAKE HER SUFFER FOR WHAT SHE DID TO MIKEY!" he snarls, tears streaming down his face.

Once they had returned to the lair, they laid Mikey's body down on the couch.

Leo was sobbing into Splinter's shoulder, murmuring words of failure.

As Donnie tried to hold Raph back, the big brother's rage was palpable.

His eyes were wild and his fists were clenched so tightly his knuckles had turned white.

"I'm going to kill her," he growled over and over through gritted teeth.

"I'm going to kill her,"
