Disclaimer: I do not and never will own the teenage mutant ninja turtles, I just love to write about them.

Chapter 14

Leo's P.O.V

"You wwwill not get away with this ttturtles" buzzed Stockman.

"And you thought you could get away with illegal genetic engineering?" Donnie mused from his place behind the desk of computers. We had destroyed nearly all the hard evidence and material of the experiment: the notes, the supplies, any samples., ext. Donnie is currently double checking for electronic data that he might have missed as well as confirming that this was the last lab.

"All good Leo, let's head out of here."

"You got everything Donnie?"

"Yep I triple checked"

"No turtles" Stockman laughed "i sttilll have the warhouse across town. Once I find the DNA I require it will be complete. You may have won today, but I will defeat you next time our paths cross"

"No Stockfly" I said shaking my head "neither you, shredder, Peirce, or anyone will ever have any super soldiers"

"Oh Yess, and once I've completed this mission I will destroy you your brothers and become Shredder's right hand mann."

The noise of approaching footsteps interrupted Leo's comeback, Donnie had hijacked the system and had turned off security systems, but Stockman had probably found someway to call backup. "Sorry stockman gotta fly" Leo smirked before shooting up his graveling hood and taking off with Donnie through the skyroof. "Come on" Leo yelled over his shoulder taking off down the rooftop. Overall things had gone well, they had destroyed all stockman's illegal work on the serum and if the others mission had gone successful at the warehouse then all serum was as good as never existent.

"If all goes as planned the others should be pulling around the corner any second" Donnie responded, his triumphant smile mirroring Leo's. A sudden wave of pain shot through Leo, over the deafening sound of the gun, Donnie could hear Leo's cry as he shakally grabbed his shoulder, stumbling backward toward the wall, in shock. "Leo" Donnie's screamed running over to his brother, as Leo sank to the ground the pain pulling him into shock.

"Not so fast turtles, you will not get away from this that easily" Tiger Claws voice rang out. "The shredder may have use of you, I have done some research although it is all now destroyed" the cat snarled as he approached. "Before you destroyed this information I learned your secret cub" the cat's smile spread across his face venomously, before turning to address Stockman and Razar who had just appeared. "Stockman here is the DNA you need to complete the experiment"

"Iz do not understand..these turtles destroyed everything.."

"No not everything" The tiger's eyes gleamed "the leader carries a secret, he may have destroyed your lab but his blood holds the DNA. He is the lab rat from Perice's experiments"

"Him?" Stockman gaped, before smiling evilly "oh this is better than expected"

"You brought the key right to us little one" the tiger grinned.

No one's P.O.V

Donnie felt chills run up his spine as he stared at the assassin before him. Donnie pushed the emergency button on his t-phone behind his back, sending up a prayer that his brother's had destroyed the pre-serum; before taking a defensive stance in front of his brother.

"Now now cub" the tigers teeth gleamed as he stared circling Donnie.

"Come on turtle it's three against one" Razer chimed, his eyes gleaming in anticipation for battle "do the math" Stockman sneered

"And I thought you were supposed to be the smart one"

"You don't stand a chance" Donnie gulped determined not to let anyone near his injured brother.

Razar and stockman raced forward simultaneously, attacking Donnie skillfully and with determination. Taking turns in their attacks so that the observant turtle never had time to think out an attack, forcing donnie to go into defense. Donnie was able to knock Stockman unconscious without much difficulty but was having trouble taking down Razar, whose attacks seemed to be getting more vicious as the fight progressed. Forced retreats sending Donnie further and further away from Leo. Tiger claw's lips spread into a viliouncious grin as Razar pushed donnie further down the rooftop leaving the downed leader completely vulnerable.

"All this time, the ingredient Stockman needed to finish his little experiment was right in front of our noses and we didn't even know it." The tiger sneered as he approached Leo, who seemed to have become aware of the dangerous situation he was presently in. Clenching his teeth down to hold back a scream of pain, Leo pulled himself onto his feat, back against the wall for support as he reached for his katanas, winching in pain as he lifted his right arm. Biting back the pain, Leo looked on his face set in a look of determination. Courageously holding his twin swords out in front of him, beckoning his opponent forward.

"Fooling child, you don't possibly stand a chance" without another word Tiger Claw leapt forward his sword meeting the fearless leaders. Despite the blood loss and the throbin in his shoulder Leo's skill, strategy, and agility coupled with peer determination were enough to keep Tiger Claw at bay.

"It is a shame Leonardo that Stockman needs you alive. You are a worthy opponent, you should die on the battlefield. Instead you shall die as a lab rat." The tiger growled ducking back from Leo's attack just in time. Leo's sword sang as it swept by the tiger's face, traces of whiskers dancing to the ground.

"Today is not my day to die" leo's ice blue eyes cut through the dark night, his face set with determination.

"Many men have often thought that before entering battle" Tiger Claw growled before leaping forward in a half spin sword flying, "they often find that they are WRONG"

"Shouldn't the guys be here by now" Mikey asked leaning out the window, gazing up as the Shellraiser pulled to a stop outside the building that stood as a cover for Shredder's lair.

"This was the meeting place" vince confirmed pulling the car into park. "Let's give them a minute, like us they might have run into enforceable distractions" as on cue everyone looked over to Karia.

"Oh come on, I did not put your stupid plan that far behind"

"Er" Raph growled, starting to pace in front of the door. "I don't like this Mr. punctual is never late, and teamed with doctor Donnie they shouldn't be running behind like this" he stopped suddenly pulling out his sias. "I'm going after them"

"Raph no" Vince stated calmly trying his best to sound like his twin (after all Leo had put him in charge, so it seemed logical to take on his standpoint in this situation.) "Were sticking to the plan knowing Leo and Don they will too, it's best just to stay put"

"Stay put..stay put?" Raph growled, pointing his sia accusingly at the blue masked turtle. "How am I supposed to stay put when our brother's could be in trouble?"

"I have to agree with Raph on this one" Karia sighed walking over to stand beside Raph.

"Well that's a first" Mikey said from his place beside Vince.

"Well yeah, Raph is usually a hot head" Karria said rolling her eyes receiving a "hey" from the red banded turtle. "But on this occasion" the kunoichi continued "the hot head has a point. I know my father even with security running low with the diversion you caused at the warehouse, the place will still be well guarded by Tiger claw at least. He rarely leaves my father's side, and even alone he poses quite a threat. We should go provide back up"

"Dude I agree" Mikey said turning his big blue eyes to the eldest brother.

Vince sighed "guys I'm worried too, but it's best if we stick to the plan we need to nnnnrr" vince suddenly grabbed his shoulder struggling to hold back a scream of pain. "Vincy" Mikey was by his brother's side in an instant "what's wrong? Are you hurt?" Mikey asked confused to find no injury on his older brother to explain the outburst. Vince shook his head slowly, fighting to control his breaths. He let his ice blue eyes travel up to meet the green and blue concerned eyes of his brothers. "Leo's hurt"

"Take that you overgrown dog" Donnie spit his kick sending Razar hurtling over the side of the rooftop and into the dumpster far below.

"Donnie" hearing his name the genius turned around just in time to brace himself enough that the hug from his younger brother didn't send him toppling to the ground. After a shocked second Donne smiled and returned the embrace, "I love you too little brother"

"Donnie are you hurt?"

"No raph I'm fine...oh no..Leo" donnie ran over to the wall where he had left Leo during the fight only to find a small pool of blood. Sounds of clashing swords pulled his attention to the other side of the wall where Tiger Claw and Leo were fighting. Leo's right arm hung limply at his side, his chest heaving the blood loss obviously taking a toll on him. "Is that all you got you overgrown cat" Leo spat, blood dripping from his mouth. Tiger Claw growled before charging forward sending a kick that knocked an exhausted Leo to the ground, his sword at the leader's throat standing over him. "Too bad we need the blood flowing through your veins, I would much rather kill you now. I've spilled so much of it already, it's a shame I won't have the honor of taking your life turtle" A sudden impact sent the cat flying into a wall. "Stay away from him" Vince spat.

"Well well, the notes said there were twins. I just thought you were dead. Too bad your DNA isn't prepared, it would be nice to have a backup in case this one dies. But I don't think our current bug of a scientist can deal with that. So I guess I'll just have to kill you" With that Tiger Claw swung his sword at Vince, who smoothly dodged and countered. Filled with rage and fury that powered his attacks, sending a startled Tiger Claw retreating away from the injured leader.

"Leo" Raph wailed raising to his fallen brother's side

"Oh no..Leo..bro can you hear me" Mikey cried holding Leo's hand. Leo moaned slightly as he tried to sit up looking around wildly for his twin whose voice he had just heard.

"Easy Leo, doesn't look like he hit anything vital, but your still losing too much blood. I'm going to need to get him back to the lair stat. Mikey help me carry him, you'll have to drive. Raph Karria, go help vince Stockman and Razar should stay down but keep an eye out just in case and get back to the lari pronto"

"Got it" Karria stated, Raph nodding in agreement before turning to his wounded brother. "Hang in there Leo"

"Mikey grab his legs, I got his shoulder, alright come on let's move"

"Tiger Claw" Karria yelled kicking the assassin in the face, before skillfully ducking into a drop kick swipe that send the tiger kurtling back. Providing the opportunity for Raph and vince to addvance, their hits and kicks sending the Tiger further back toward the edge.

"Its over Tiger Claw, the pre-serum and all Perice's notes are destroyed. The super serum is as good as gone, like it never existed"

"You and your master failed, catnip its over" Karria spit.

"And you never ever better come near me or my family again" Vince growled his twist kick sending the overgrown cat flying over the edge of the roof and into a garbage truck below.

"That should do the trick" Karria stated after a moment "he shouldn't be bothering you for a while at least"

"Yeah maybe the taste of trash will make him rethink some life choices" vince mused optimistically.

"Come on guys, we should move" Karria said after a moment, and the three ninjas took off into the night.
