His feet pounded against the hard stone of the roof as Mikey sprinted close behind his two older brothers. His blood felt heated and adrenaline rushed through his veins. Time was of the essence, as Leo kept reminding them, and Mikey kept hoping that by some miracle, they weren't too late. He pushed his muscles to the limit as they hopped rooftop to rooftop. He was tired, but he needed to keep his focus; his brother's life depended on it.

His bright blue eyes shone with determination as they locked onto the tiny form of Bebop on the street below. The warthog in the flamboyant purple jumpsuit was zipping along on his motorcycle through the Upper West Side, completely oblivious the three turtles on his tail as he sped toward the riverside district.

It had been three days since Donnie was taken while searching for parts in the scrapyard. When he didn't come home that night, Leo, Raph and Mikey had all gone out to look for him. After they found his phone crushed and thoughtfully left for them at the scrapyard, they had really started to worry.

They had searched everywhere, even going to the burned out shell of Shredder's lair to investigate. It had been close to a year since the Shredder had fallen, and though he was no longer a threat to them, Rahzar, Bebop and Rocksteady were still out there and still very dangerous. They were likely suspects, but unfortunately, that list was fairly long. Donnie was nowhere to be found, and the atmosphere in the lair was heavy with tension when they returned empty handed.

It didn't take long for Leo's tactical brain to start working overtime. He got the idea that the street gangs may know something. Mikey and Raph had shared a look and a grin when their brother put this idea to them. The youngest knew his brothers better than about anybody. Beating up gangsters for information was among their favorite things. That, and jelly bean and garlic pizza.

The Purple Dragons, though a bunch of boneheads, were smart enough to talk when the angry beast, also known as Raphael, started shaking them down. After a good deal of intense interrogation, and several broken noses, they learned that Shredder's lackeys were the ones who had taken Donnie and did have him hidden away somewhere, though none of the Dragons seemed to know where.

They had staked out Shredder's old base for two days, without success. Everyone's nerves were on edge, especially Raph's, though Leo was having difficulty keeping himself composed as well. Trying to keep his brother's from going off the deep end had been a Herculean task, but Mikey was up for the job. It was among many of the things that he did best.

Finally, Bebop showed his ugly mug around the abandoned building. Raph had first spotted the mutated thief sneaking through a window when his cloaking device failed for a minute. He cursed and struck the device, which reactivated and hid him from sight. An hour later, he reemerged, carrying a box of Stockman's lab equipment that he loaded onto the back of his motorcycle. Climbing onto the bike, he revved up the engine and sped off down the street. The turtles followed close behind, silent as shadows.

Bebop turned up a deserted side street that lead to an abandoned cannery warehouse. Leaning into a hard right turn, he drove the motorcycle up the ramp into the warehouse's loading docks, disappearing into the darkness. The three brothers stopped on the roof directly across the street. Raph unsheathed his sais, spinning them in his large fingers.

"Come on, let's get Donnie out of there!" Raph growled impatiently and stepped up on the ledge. Leo grabbed his arm, holding him back.

"Hold on, Raph. We aren't even sure that that's where they're keeping him."

Raph shifted his weight and threw a glare at his older brother. "Where else could he be? We destroyed Shredder's lair when we took him down, so his goons had to go somewhere!"

Mikey couldn't bear the sight of his two oldest brothers butting heads like this. In fact, it really annoyed him, since it was wasting time. He stepped forward and placed his hands on their shoulders.

"Guys, can you not do this now? D could be dying in there!"

Leo's expression softened, then he shrugged off his brother's grasp.

"Alright."

Shooting a look at Raph, he folded his arms. "If we are going to go down there, we need to stick to the shadows and scout it first. We can't just go in there blindly."

"Fine." Raph bit out, sheathing his sais with a huff.

In a fluid motion, the three of them climbed down and dashed across the street. They stuck close to the outer wall of the warehouse, using the shadows to their advantage. Things seemed clear on the outside as they scrunched down next to a dumpster full of construction waste.

Mikey felt Raph place his hand against his plastron, reminding him to stay close to the wall. A frown formed on his face. I know how to be stealthy, he thought to himself bitterly, I don't need these guys holding my hand through this.

They huddled close together, the silence nearly deafening as they carefully observed their surroundings. Not a single sound could be heard anywhere, not even the scampering of little rat feet. It was unnerving and Mikey felt a chill shoot down his spine.

"You would think a warehouse would have some noise," Leo whispered hoarsely as he shifted closer to Raph. His brother nodded shortly in agreement, his wide green eyes roving the surrounding uncertainly.

The three turtles inched along the side of the building until they made it to the back corner. A smirk spread across Leo's face as he pointed upwards. Mikey and Raph followed their brother's gaze. Above some metal crates against the wall were a row of large windows, their glass panes propped open. The leader made a series of complicated hand signals and the three of them climbed up the boxes. The windows were still four or five feet out of reach, even standing on top of the crates.

Leo cupped his hands and gave Raph a leg up, getting him closer to the window panes. Raph carefully eased one of the windows further open, and slipped inside without a sound. Mikey stepped into Leo's hands and grabbed Raph's outstretched forearms, allowing his big brother to pull him inside. Together, they pulled Leo up and through the window.

They stuck to the shadows and hopped down behind some large conveyer lines. Mikey peeked around a stack of rusty machinery and instantly recognized the towering figures of Shredder's goons. His blue eyes grew wide as he took in the sight before him.

Rahzar and Rocksteady stood in a semicircle around Donatello, who was was curled up on his side on the floor. Bebop was unloading the lab equipment onto a long table, pushing aside piles of trash to make room.

Donnie slowly eased himself up off the floor, holding his side. Blood oozed from a large gash, dripping off his fingers onto the concrete. Rahzar loomed over him, the tips of his claws stained with dark rusty patches.

"I'm not going to ask you again," the dog mutant growled darkly as he flexed his bloodstained claws.

Donnie coughed painfully, struggling to push himself to his knees. He held his middle tightly with both arms and ducked his chin into his chest.

"I already told you," Donnie wheezed, his reddish-brown eyes gleaming with defiance, "I won't make it, so you might as well kill me."

"This is waste of time," Rocksteady commented, swinging his hammer into his open palm menacingly, "Let us just crack his shell and get it over with."

"No, you fool!" Rahzar stepped in front of him. The two large animals squared off fiercely, Donnie seemingly forgotten.

"We need him alive!" Rahzar snarled, "He's the only one who has successfully created the retromutagen." He lifted his finger and pointed towards Rocksteady's chest. "Don't you want to be human again?"

Rocksteady grumbled reluctantly as he roughly pulled Donnie to his feet by his arm. The wounded turtle swayed heavily as his knees buckled. The rhinoceros snarled in Donnie's face, nostrils flared irately.

"If the turtle knows what is good for him, he will start making retromutagen and stop wasting the time." He tipped Donnie's face upward with the broad side of his hammer, forcing the turtle to look him full in the face.

A hard lump formed in Mikey's throat as his indignation rose to fever point at the sight of his brother's bruised and swollen face. He couldn't take this anymore. He had to save his brother and he had to do it now.

"Booyakasha!" Mikey gave his signature battle cry as he charged toward the group of mutants.

"Mikey, wait!" he heard Leo cry out behind him.

Too late, the duo saw the youngest turtle charging out at them, and Rahzar quickly shoved Bebop aside. The warthog stumbled back a step, taken aback by the brash action.

"Yo, watch your claws fool, this is a brand new suit!"

Rahzar gave a grunt and ignored the warthog. He swung his head around and bared his fangs at Mikey, preparing to strike. Before he could even make another move, Raph dove down and planted his foot in his face, sending the dog-like mutant flying backwards. Leo sprinted past, katanas raised, headed straight for Rocksteady. The irate rhinoceros gave an indignant roar, swinging his hammer at Leo's head.

"G-guys," Donnie sputtered out after a coughing fit. Mikey made straight for him, helping him to his feet.

"Come on, Donnie. We gotta move, bro."

He wrapped his brother's long arm around his shoulder to support him. Blood was still gushing from his wounds, and as Mikey got a closer look at him, he realized that his skin was extremely pale. Donnie leaned on him heavily, his breathing shallow and labored. He issued moans of pain as he clung onto his brother, trying to keep himself steady on his feet.

"Hang on, D. Just a little farther," Mikey coaxed, willing Donnie to move faster; even a little bit.

Somehow he managed to get Donnie a few feet before his brother collapsed against him in a coughing fit. He tried to urge his brother to keep moving as he glanced around at the skirmishes going on around them. Raph was parrying the wide slashes of Rahzar's large claws. The loud clangs of metal striking metal, mingled with grunts echoed throughout the warehouse. Leo had knocked the hammer from Rocksteady's hands and was now dodging the wild swings from the metal sickle.

"Hey, we need to move!" Mikey cried urgently, tugging on his arm. Donnie's muscles spasmed violently as he tried to move faster. His legs failed him and he sank to his knees, breathing heavily. In a panic, Mikey put all of his strength into heaving his brother to his feet again.

He managed to hoist more of Donnie's weight onto him so that he could carry him, but Bebop zipped right up to them and tried to land a blow to his head. His fighter's instincts kicked in, and he immediately knocked him away with his nunchucks. The warthog cried out in pain before turning on his invisibility device.

"Yow! You think you can take me, punk?"

Mikey released the chain of his kusarigama and threw it at the space where he last heard Bebop. A loud thunk, followed by an exclamation of pain told him that he had hit his mark. The invisibility stuttered, revealing the warthog for a fraction of a second, before completely camouflaging himself again. Great, this is gonna get annoying, Mikey thought bitterly.

Once more, he threw his weapon towards the incoming time the chain flew by unhindered, only striking thin air. The weighted chain fell to the concrete floor with a clatter.

"Mikey, what are you doing? Get Donnie out of here!" Leo shouted as he dodged Rocksteady's horn.

Mikey whipped his head back toward Donnie with panic in his eyes. Donnie clung onto Mikey for dear life as his wounds continued to bleed unhindered. His eyes were becoming cloudy and his head lolled forward. It was evident that he was struggling to maintain consciousness.

"Donnie! Bro! You gotta stay awake. Stay with me!" MIkey cried out in desperation, giving his brother a little shake. Donnie's brown eyes fluttered rapidly before he deliberately blinked, trying to keep his eyes open.

"I'll… try," he breathed painfully.

A loud hum sounded off to their right and Mikey leapt to the side, covering Donnie with his shell. The laser struck him in the arm, causing him to stumble to the ground. A jolt of pain shot through their bodies from the impact. An agonizing cry of pain erupted from Donnie; the pain was just too much for him to bear.

Mikey realized at that moment, he couldn't fight off Bebop with his brother hanging onto him. He was just too much dead weight. To keep his brother safe, he needed to set him down somewhere. He tried his hardest to ignore the searing pain in his arm; it was nothing compared to what Donnie must be feeling.

After calming his nerves, he shrugged off the pain and pulled himself to his feet. Adjusting his brother's weight, he used both arms to lift him up off the ground in a fireman's carry. There wasn't much time, and at the moment the warthog outclassed him in speed.

He glanced around, turning and twisting his head as he searched for a safe spot. Immediately, he noticed a stack of wooden crates next to the back corner of the room. Most of the fighting took place in the center, so it seemed like a good idea to place him away from the fray.

Using all the muscles in his body, he pushed himself as fast as he could to the corner. The shadows completely covered the back side of the boxes, so Mikey deemed it perfect spot to hide his brother. He used his legs to push aside some of the boxes and eased Donnie down into the makeshift hiding spot.

"Hey, pay attention to me! Whaddya' think you're doing?" Bebop sassed out as he closed in on them, his lasers humming loudly.

Mikey quickly threw a glare over his shoulder before giving a comforting look to his injured brother.

"Stay put. I'll be back before you know it." He sprinted away before Donnie had the chance to object.

"Come and get me, pork chop!" Mikey catcalled, turning and shaking his tail in Bebop's direction. The warthog indignantly snorted as he fired a couple of rounds from his laser gun at his head. The turtle nimbly cartwheeled out of harm's way, finishing off with a neat backhandspring.

"Ha! Missed!" He stuck out his tongue and blew a fat raspberry at the warthog. Bebop's ugly grey tusks jutted forward as he growled at his tormentor.

"Why you little shit!"

One of the lasers shot past Mikey's head and shattered a crate behind him. Wooden shards scattered out everywhere, followed by a puff of black smoke. Uh oh! Now he was in full panic mode. He needed to lead his attacker away from his older brother before they were both vaporized.

"Hey, watch out!" Raph called as he hurled Rahzar in their direction.

Bebop didn't have time to react as his ally crashed into him. Mikey dove into a roll, barely having any time to dodge the incoming disaster. The two mutants flew headlong into the wall and slid down into a huddled heap.

"Move your spiky boney ass, you oversized mutt!" Bebop's protestations were muffled under Rahzar's weight.

"No, you get off of me, pig!"

The two brothers stood there and watched as their enemies wrestled, rolling around and screeching at one another. Mikey could hear Raph huffing as he glared at the pair of struggling mutants. Before he could make a move, he felt something slam against his shoulder. It happened all too fast, but the next thing he knew, Leo was on top of him with Raph kneeling down beside him, huffing out as he shrugged off the blow.

Rocksteady stomped over to them as they tried to regain their footing with a menacing gleam in his eyes. He swung the hammer over his shoulder, preparing to make a blow at his oldest brother. Mikey's eyes widened as the hammer sliced down towards them.

"No!"

Using his quick reflexes, he wrapped his arms around Leo and rolled to the side. He felt the shock pulse through the ground under him as the hammer struck the floor, sending a shower of concrete pieces flying in all directions. Several shards struck him in the shell as he tried to refocus himself. His muscles started quivering when he realized that they barely dodged being flattened like pancakes. Fear struck his core as the rhino dislodged his hammer, preparing to deliver another swing.

"Leave them alone!"

Raph hooked the rhino's arm with his sais, struggling to hold it back. This bought Mikey enough time to help Leo to his feet. Rocksteady quickly overpowered Raph, and tossed him toward the side of the building. He flew into the wall, making contact with a loud groan.

"Raph!"

Mikey feared for his brother, but the sensation instantly seeped away once his brother hoisted himself on his feet. His emerald green eyes shone with rage as he grinded his teeth, shaking off the impact. There were a few scratches on him, but nothing life threatening.

Man, the rhino-man is seriously tough, Mikey thought to himself as he glanced at Leo. Obviously, his skirmish with Rocksteady had taken a toll on him, because his knees were shaking and there were cuts and darkening bruises all over his body.

Suddenly, a loud crash sounded behind him. Flinching, he knew what was coming, and he dove to the floor, pulling Leo down with him. Lasers shot over their heads, striking Rocksteady in the chest and causing him to screech in agony. A loud metal thump rang through the warehouse as his hammer slammed into the ground.

As another round of lasers fired, Mikey tugged Leo along with him. Raph used the opportunity to tackle Rocksteady to the ground before he sprinted after his brothers. This only seemed to piss off their enemies even more. Bebop became trigger happy, shooting at all three of them in a craze. His shots scattered out everywhere, without aim or purpose.

"We have to get out of here!" Leo cried as he shrugged his brother off of him.

Leo shoved him forward as shouted over his shoulder for Raph to follow. Mikey looked back and his blood froze in his veins when he saw the stacks of crates. He had to go back for Donnie. I'm the only one that knows where he is! He pushed past Leo, and made a mad scramble towards the back of the warehouse.

"Mikey! Where are you going?" Leo called after him.

He pushed his legs to the limit, ignoring Leo's calls. After all, they came all this way to save Donnie, and he refused to just leave him. He just couldn't. However Bebop locked his sights onto him, and shot off a barrage of lasers, firing with everything he had.

"Hahahaha! Who's the porkchop now!" The warthog cackled out maniacally.

Mikey flipped upwards to let the rounds pass underneath him. One of the lasers struck a stack of dark barrels, igniting a fiery blast. The force of the blast propelled him backwards, all sense of security was stripped from , he felt Raph's strong arms grapple him and attempt to drag him away. Heat flared up from the wreckage, and the roar of the explosion was deafening. Debri rained on top of them, and a sense of horror shot through him as he watched Donnie's hiding spot go up in flames in front of his eyes. A large section of the wall had been knocked down, revealing the river beyond the docks.

He saw the shape of what he knew was his brother, flying through the air in a stream of smoke, straight towards the water. His heart pounded relentlessly in his chest and his blood grew hot within his veins. Tears threatened to spill from his eyes as he struggled to tear away from Raph's clutches.

His voice broke free from his throat, tearing it raw.

"DONNIE!"
