"H…hello? Guys?"

Donatello looked around nervously. He was surrounded by darkness. An uncomfortable darkness.

He started to walk, but seemed to be stuck on the spot he was standing on.

"What the shell?"

He again tried to move, but no use. Suddenly he heard something.

"Hello? Mikey?"

Donny turned around to where the sound had come from. "Mikey, if that's another one of your pranks -!" A loud growl was heard. Donny whirled around. "M…Mikey?" Don saw something move. He took a few steps near it, surprised at the fact that he was able to move. Slowly making his way towards the shadow, Donny's eyes narrowed. Suddenly he heard a loud roar. His eyes widened.

"No…"

Blood red eyes stared back at the turtle. The figure blinked once.

"WHOA!" Donny felt himself being pulled inside the ground, the eyes still staring at him.

And then he fell. Donny screamed in fear.

To his surprise he landed inside their lair.

"Ow…what the -?"

Donny got up and rubbed his head. He looked around. Everything seemed just normal.

CRASH!

Don whirled around. Mikey was lying on the ground. He had crashed through the wall of Donny's room. "MIKEY!" Mikey didn't seem to hear him. The orange banded turtle struggled to get up.

"Donny, no!" Don's eyes widened. Why did Leo -?

Another loud roar. And Leo was sent through the wall. Donny was too startled too move.

"Leave 'em alone!" And another loud roar. This time it was Raphael who crashed through the wall. Donny trembled in shock and disbelieve. What was going on?

"Guys!" The purple wearing ninja ran towards his brothers, wanting to help them up.

He bent down to take Raph's arm, but…

It wasn't tangible. Donny couldn't touch his brother.

The second youngest ninja looked at his hands, then at his brothers. They didn't even seem to notice him. "What in the shell -?"

The wall cracked open once more. A big dusty cloud prevented Donny from seeing the cause. Leo, Raph and Mikey stood, eyes wide.

The cloud vanished. Donny gasped. A big, croc-like turtle was glaring at the three injured turtles, its blood red eyes shining bright.

Donatello couldn't believe what he saw. "No…no, this can't be!"

The monster roared loudly and swiped Raphael against the next wall. The red banded warrior growled his famous growl. Leonardo and Michelangelo jumped onto the monster, trying to calm it down.

"Donny, stop it!" "That's not you!"

This only let the monster's rage grow. It grabbed the orange clad turtle and threw it against Raphael.

"Mikey!"

Then the monster grabbed Leonardo and crashed him onto the ground, its left claw at the leader's throat.

Mikey's eyes widened. Raph screamed. Donny only stared.

Leo looked at the monster, his voice hoarse: "Donny…little brother…no…"

The monster growled louder than ever and raised its right claw.

"LEO!"

After one blink the scene was gone. Donny was back in that dark black place, still in shock and breathing heavily.

He fell onto his knees, whimpering. This didn't just happen, it couldn't -!

Don heard a slight growl. He looked up, hatred in his eyes. The blood red eyes were still staring. Don awaited the monster, the mutant, to finally come out of the shadows, to face the turtle.

Steps were heard. The figure stepped out of the shadows.

Donatello's eyes went wide. A gasp escaped his throat. His body started to tremble.

He was staring at himself.

"NO!"

Donatello darted up in his bed, breathing uneven, heart racing.

This hasn't just been a normal nightmare. It was too different from the others.

"Donny?" "You okay, bro?" "What's the matter?"

Don felt arms wrapping around his body, hands patting his head and running over his chest.

He was trembling. The pain in his leg had gotten much worse. The nightmare was still flashing inside of his mind. It killed him on the inside

Soothing circles were rubbed on his shell. "We're here, little brother."

His sweating head was caressed. "Don't worry, Donny."

His chest was stroked. "Ya bros are protectin' you, kiddo."

He killed Leo.

"Calm down", Mikey whispered.

He killed Leo.

"Nothin's going ta hurt ya", Raph soothed.

He killed Leo.

"Just relax", Leo cooed.

Don killed Leo.

It wasn't just Don's mutation who killed Leo. Don did it. Don did it himself.

"We're right here." So what? What was the use in them being here?

"It's alright." No, it wasn't!

"Just a nightmare, bro." No, it was not 'just a nightmare'!

Donny felt it. He killed his brother. Donatello killed his big brother.

A sharp pain ran through his leg. Donny winced. He looked down at his leg.

The muscles were growing.

Don screamed. He pushed his brothers away. He flew out of the room, leaving his brothers with startled expressions on their faces. Leonardo clenched his fists. "No…"

Raphael smacked his arm.

"Snap outta it, Leo! We gotta go after Donny!" Leo looked at him…and nodded. With that, the three brothers went after the purple clad turtle, which was almost out of the lair.

"Donny! Wait!"

Tears were welling up Donny's eyes. The pain in his leg was unbearable.

*Stay away,*, Don thought desperately, *Stay away from me.*

The pain was getting worse. And worse. The muscles were growing faster. Rage was boiling up Donny's chest.

"No, NO!"

He collapsed onto the ground, gripping his leg, trying to stop the muscles from growing. But he knew that wouldn't have any use.

The growing muscles had moved up to Donny's belly, chest, hands. Don looked at them, with begging and hopelessness.

"No, no, please!" Donny sobbed, moaned in pain, cried. He was so scared!

His brothers caught up to him. They froze at what they saw. Leo started to tremble.

He shook his head. "No…this can't be. Not now. Not now!"

Don had jerked up. He was standing, his whole body trembling and the muscles growing.

He turned around.

His brother's gasped.

Donny's eyes were shining in a blood red color.

And he whispered, his voice deep and so different from his usual voice. It was filled with begging.

"Help…me…"

The three brothers just stared. Donny let out a blood freezing scream.

The next thing he knew was that he was hungry. His stomach longed for food.

His eyes caught a pleasing meal. His prey seemed to be horrified.

How much he loved that!

Donatello growled and darted forward. His prey dodged, eyes wide.

Oh, how much Donatello loved to play with his food! He whirled around and growled again.

One of his sacrifices was protecting another one, with an orange bandana.

Donatello growled. He immediately knew which one of his three sacrifices he wanted first.

He darted forward to the orange and red banded beings. The red one let something like a growl escape his mouth. Pathetic. The orange one seemed uneasy over something. He kept trying to get away from the others protection, but then he clung onto him in fear.

Donatello heard a voice.

"Donny, no!"

He didn't care. He was close to his food. He raised his claw and stroke the red being against a wall.

The orange one's eyes widened. "Donny, no! Wait!"

Donatello roared.

SWIPE!

The orange clad being fell to the ground, unconscious.

Donatello made his way towards the being, to finish it off.

"Donny, stop it!"

Donatello's eyes widened!

"Don't ya dare ta touch Mikey!"

He had started trembling.

"YOU ARE GONNA PAY FOR THIS!"

.

.

.

Realization found its way into Donatello's face. He sunk his claw. What did he just do? He tried to kill his little brother! Mikey was lying on the ground, unconscious, because of him!

Donny shook his head. He trembled back from the on the ground lying turtle and ran.

He ran and ran and didn't take a glance back. His monster body made him able to bust through the wall of the lair, out in the sewers.

Leonardo and Raphael ran towards their baby brother.

"Mikey? Mikey, wake up!"

Raph was holding the youngest close and shook him slightly.

He looked up to Leo.

"Leo, what just happened?"

Leo was about to answer when he heard a gentle, but firm voice.

"My sons, what is going on?"

Both, Raphael and Master Splinter were now looking at Leo.

The blue clad turtle took a deep breath.

"Donny is having a relapse."
