I do not own the TMNT show or any of the characters (I do in my dreams). I only own this fanfiction. Thank you to my awesome little brother for this AWESOME idea. I really didn't want to start a new story, but the idea was fresh in my head and I just had to!

Enjoy! :3

"Don't worry Timothy. I'll turn you back to human." Don told the canister holding Timothy. Donnie was sitting in the garage that doubled as his lab. Carefully, he was mixing chemicals to try to turn Timothy, a.k.a. The Pulverizer, back to human. At the moment, Tim was a bunch of organs surrounded by goo in a giant canister.

At first, Don was kind of disgusted by the floating eyes that would watch him as he worked, but now he was used to it. Don hoped that the chemical would turn human and make him STAY human.

"Hey Donnie." Leo said, walking in.

"Hey Leo." Don said without looking up. He stuck his tongue out in concentration.

"Have you figured it out yet?" Leo asked, pulling up a seat next to Don.

"I think I have. I'm about to test it. Can you get a few robes or something in case it does work?" Don said, standing up. Leo left the room to get the robes. He picked up four and walked back in.

"Okay, here." Leo said, laying them on Don's desk. Don held the oversized test tube up, inspecting it one more time before he used it.

"Prepare to be human Tim." Don said, twisting off the lid to the giant canister. Slowly, he held the chemical over the top. As he began to tip it, Raph and Mikey ran in. Don held the test tube upright.

"Leo! Tell Raph to stop chasing me!" Mikey yelled, running close to Don.

"Tell Mikey to stop giving me giving me reasons to chase him." Raph said, catching up to his little brother.

"Go away guys!" Don said, taking a step away from the canister.

"Be careful! You might break some—" Leo was cut off. Mikey ran to close to Don and bumped into him. Don fell to the ground, letting go of the test tube. Don fell into Leo and Leo fell into Raph and Mikey. The four turtles were piled together in the middle of the room.

The test tube flipped around in the air, spilling the chemical everywhere. The chemical landed on the four turtles and the empty test tube fell to the ground, shattering. They all cringed. The chemical stung and burnt their green skin. Raph tried wiping the stuff off, but it didn't work. The chemical had already seeped into his skin. Mikey curled into a ball on the floor, wrenching in pain. Leo was on his knees and held his head.

Don shot up and grit hi teeth. His eyes were shut tight to keep the chemical out. He felt his skull changing shape and it hurt badly. The pores on the top of his head opened and hair grew out. Don felt his two fingers split, creating four long and skinny fingers with one thumb. Finger nails pushed up through his finger tips. His shell fused into his back, creating his spine. He felt his feet get skinnier, two of his toes splitting apart like his fingers. The toe that didn't split got smaller and took shape into his big toe. Toe nails sprouted up though the matrix and covered the tops of his toes. He felt himself grow a few inches taller, his body stretching. Don fell to the ground, gripping his head.

The next morning…

Don woke up with his teeth grinding. He slowly sat up and looked at himself. He immediately jumped up and put on a robe.

Good thing Leo got four robes! Don thought as he laid a robe over each of his brothers.

Mikey was the awake. He sat up and screamed. Leo ad Raph shot awake. Raph wrapped his robe like a towel around his waist.

"What? What happened?" Leo asked, jumping to his feet. He looked down at himself and blushed. Quickly, he grabbed the robe off the ground and wrapped it around him.

"You're human!" Mikey yelled, pointing to all his brothers, "I'm human!" Mikey pointed to himself. The four boys rushed to the bathroom to look at their reflections.

Don had stringy, light brown hair that almost reached his shoulders. His eyes were still far apart, but his nose filled the space a bit. His face was long and skinny. He smiled and say the big gap where a tooth used to be.

Mike had blonde curly hair. Freckles lined his cheeks. His face was round and childish. His baby blue eyes sparkled.

Raph grinned at his new look. He had spiky, dark red hair with some in his eyes. His face was very pointed. Where his neck met his shoulder, Raph noticed a big lightning shaped scar.

Leo gave a sideways smile at himself, Karai was right. I AM adorable. Leo thought. He had dark brown hair with bangs. His face was a little angular. He looked at his dark blue eyes and gave a toothy smile.

"We're humans!" Mikey yelled, turning to face his brothers, "High thre— I mean, uh, high five!" Mikey said, his hand shooting in the air. His brothers smiled and gave him a high five.

"What's going on in here?" Splinter asked as he opened the bathroom door, "What did you do Michelangelo?" He asked, looking down at the little blonde boy.

"Why is it always my fault?!" Mikey asked, putting his hands up in defense.

"What happened?" Splinter asked Don and Leo.

"I was trying to turn Timothy back to human when Raph and Mikey ran in and bumped into me. I spilt chemicals all over us." Don answered, "This will probably wear off within a week or so. I'll do some tests to see how the chemical affected out DNA." Splinter nodded.

"You all need clothes. I'll see what I have in my room." Splinter said, leaving. Don lead his brothers back into his lab.

"I'll need a blood sample," Don said, sitting down at his desk.

"Then get one from you." Mikey said.

"You didn't let me finish. To get good results, I'll need a sample from ALL of us" Don said, picking up four needles. Mikey's eyes widened and he started to leave. Raph grabbed Mikey's arm and pulled him back.

"Come on Mikey. You can go first so you can get it over with." Don said. He stood and started walking over. Mikey's pupils were the size of pinpoints. Leo and Raph held his down by the arms as Don took the sample. Mikey's eyes were watery and his face was very pale.

"Is it done? Is it done?" Mikey asked over and over, his eyes closed. Don finally got the sample (Mikey had been able to stay still for five whole seconds).

"You're done Mikey." Don said. Leo and Raph released and sat down, out of breath. Mikey collapsed into his seat.

"Sorry." Mikey said, twiddling his thumbs.

"It's alright. We know how you are around needles." Don said, getting the sample from Leo. Leo cringed a little then relaxed. Don walked over to Raph and quickly got the sample. He sat the three needles down and picked one up for himself. He bit his lip as he stuck the needle into his own arm. He scanned the blood and results popped up on his computer screen. His brothers gathered round.

"So?" Leo asked, leaning up.

"So what?" Don asked, scrolling down the page.

"What does it say egghead?" Raph demanded.

"Well, according to this, there isn't one trace of turtle in our entire bloodstream. We really ARE humans. For good." Don said, spinning around in his chair.

"Really?" Leo asked, dumbfounded

"Like, live normal lives humans?" Mikey asked, jumping up.

"Is there any other kind? Don asked, standing. All four boys cheered smiles on their faces.

"We can go to the surface during the day!" Raph said, "Without having to hide!"

"We can go to school!" Don said, him and Mikey fist bumped.

"Yay, school." Raph said sarcastically under his breath. Don rolled his eyes.

Maybe April will actually like me now, since I'm human. Don daydreamed, smiling like an idiot.

"What are you smiling for? Excited for school?" Leo asked Don. Don snapped out of it.

"Yeah. Sure." Don said, walking away.
