...

"Donnie?! What's that?" The four brothers were currently at a Kraang base, searching for whatever their plan was. They knew something was up, because there communicator orb had gone off. They were, at this moment, staring down at a giant container full of..well..they didn't know yet.

"How am I supposed to know!?" Donnie asked in a whispery tone.

"Because your the smart one!" Raph said.

"Ok...umm...it looks like...blue..mutagen?" He said, examining it awfully well from where they were.

"what does it do?" Mikey asked, also expecting him to know everything.

"Again...I DONT KNOW!" He screamed.

"Kraang heard the one known as the turtles from what is is known as the ceiling." They heard Kraang bots start firing up at them.

"Nice job Donnie!" Raph scolded. "At least now I can bust some Kraang heads." He said, jumping from the ceiling, everyone else following.

They all parted, screaming a battle cry with their weapons in hand. Donnie, with his bo staff, began spinning it, reflecting all the blasts from their guns. He then began hitting each one, jumping in the air doing flips. Meanwhile, everyone else was doing their own thing.

"Kraang! Kraang must protect project 1517!" One robot yelled. Donnie quickly looked up at the giant container of blue mutagen.

"Project 1517? Maybe I can use it for retro mutagen!" He said to himself. He started to climb up to the top of the container, while the Kraang bots were distracted, or so he thought...

"Donnie!? What are you doin bro!?" Mikey screamed.

"Donnie? DONNIE! STOP!" Leo demanded. Donnie ignored them while focusing on climbing.

"Almost...there...yes!" Donnie reached the top, looking down on the blue mutagen. "Hold on! Im gonna see if I can use it for retro mutagen!" He yelled to his brothers. Donnie grabbed a small container(I don't know where. In these sort of things they just show up.) and very carefully no to touch the mutagen, he filled the small container.

"DONNIE! LOOK OUT!" Leo screamed, cupping his mouth. All of his brothers looked up at him with terrified faces.

"DONNIE!" They all said in unison. Donnie looked down at them in confusion, then when he was about to climb down, he felt himself loose his balance, from something behind him forcefully jabbed him.

"Wooaahhhh! WooooaaAAAAHHHHH!" He screamed swinging his arms back and forth, trying to keep his balance. He heard three gasps, when he finally lost his balance, began to fall into the mutagen.

"AHHHHakslkjealcnekjx!" He fell into the electrifying mutagen. It felt like electricity was flowing through him, and it felt..amazing!

At first he thought he was dying and drowning. But then, once he realized, he felt.. incredible! He began to swim through it, doing flips, swirling around like a ballerina.

He reached the top, and looked down at his three brothers.

"Donnie..your..your ok!" They said.

"Not only that! I FEEL GREAT!" Donnie exclaimed. He jumped out of the mutagen and onto the ground before them.

"Lets go! I have the mutagen!" The four ran out of the building as fast as they could.

...

"So...what happened?" Leo asked as they walked into the lair.

"I don't know exactly, but it felt amazing. It felt electrifying. But in a," Donnie yawned tiredly mid-sentence." good way." His eyelids were as heavy as boulders.

"Bro? You tired already?" Raph asked.

"I don't know," He then yawned louder this time. "why. Im gonna go to bed...see ya." Then walked off to his bedroom, leaving three confused human sized turtled.

"Lame." Raph said breaking their silence. Raph walked off to the kitchen to grab some pizza, with Mikey following. Leo still stood there, being filled with worry for his brother.

Leo then walked into the kitchen too.

"Do you guys think the mutagen might of done something to Donnie?" Leo asked. Mikey and Raph both starred at him blankly.

"Uhhh...maybe..but he seems fine to me." Raph answered.

"Yeah bro! Chillax! He's fine!" Mikey said, swinging an arm over Leo's shoulders.

"Okay..but I'm still gonna talk to 'im in the morning." Leo said, grabbing another slice of pizza.

(Donnie POV)

I felt like my whole body was boring in fire. Everything ached in pain, but for some reason, I couldn't seem to do anything. I could do was lay on my bed, with my eyes closed, feeling incredible pain throughout my body. I felt the need to scream for help, but all I could do was just...lay there.

It was almost like, I was transforming or something..OH NO! The mutagen! Maybe it did something to me! Im totally freaking out now! But I can't do anything! I need to warn my brothers! Sensei! APRIL! Oh how I love April. Why do I have to be such a screw up around her!

Enough thinking about April, I thought to myself, focus Donnie. Just..wake up. Then the pain will end, hopefully, then you can ask for help!

Easier said then done, or should I say thought then done.

Before I could attempt anything, I felt deep slumber over power me.

Well, thats the first chapter! DUN DUN DUUUUUNNNN! Please tell me what you think! :D
