Chapter 1: Mysterious liquid
A/n: Hello everybody! Since my first story Choices was liked by some of you, I give you my second story: "Experiment 107". You might be wondering what that is, but you'll find out in the story. It's main character is Donnie (who else?), but he won't be in every chapter. Have fun reading!
It was a daily patrol. The four turtles jumped from rooftop to rooftop. Suddenly they saw footbots brake in in a science lab. They waited for the bots to come out, and then they attacked. One of them was holding a canister with an unknown yellow liquid in it. He tried to get away while the others distracted the turtles, but Leo spotted him. "Donnie!', he yelled, "Behind you! Don't let him get away!" Donnie turned around and ran after the fleeing footbot. While running, he threw his bō staff like a spear and the knife in his staff hit the head of the bot, causing it to fall. Donnie picked up the canister. The label said: "Experiment 107". "What is it, Donnie?" Leo asked after the fight was over. "I don't know", Donnie answered, "But I will find out after some tests." "Let's head back to the lair then" Leo said.
Back at the lair, Mikey ran to the TV to watch one of his favourite shows, Raph went to his dummy to blow off some steam and Donnie headed for his lab. He closed the door and gathered some chemicals. He putted one drop of the mysterious liquid under the microscope and looked. "Interesting" he muttered to himself. Then he poured a little of the liquid in a test tube and poured another chemical in it. Nothing happened. He wrote down everything he did and saw. He did some powder in it and it turned brown. "Fascinating." He grabbed his laptop and searched information about experiment 107. He found out that a Russian scientist was working on it to get rid of evil, but it was unfinished and very dangerous. It can be used to make a villain good, but it can also be used to turn someone evil. But the guys didn't know that. Donnie went on experimenting until the liquid turned red and exploded. At least, the part he was working with. The rest heard the explosion and rushed to the lab. Donnie was on the ground, unconscious. They tried to wake him up, but without any luck. "Donnie? DONNIE, wake up bro!" Mikey said. "What happened?" Raph asked. "I don't know. I heard an explosion and went looking", Mikey answered, "When I came in, Donnie was already like this." "Raph, get Splinter", Leo ordered, "Mikey, help me get Donnie to his bed." "Okay" Raph and Mikey said. Raph left the lab to get master Splinter while Mikey and Leo carried Donnie on the bed in his lab. "What has happened, my sons?" It was Splinter. He entered the lab and looked at Donnie. "We don't know. We heard an explosion and went looking", Leo explained, "When we came in, there was a bit of red smoke, which faded quickly. Then we saw Donnie lying on the floor, unconscious." "Red smoke? Was he experimenting on something red?" Mikey asked. "No, I think he was experimenting on that canister we got from the footbots. That wasn't red, it was yellow" Leo said. "Leo? You have to see this" Raph said. It was the glass bottom from a test tube with one red drop in it. "Is this the cause of the explosion?" Leo asked. "It sure looks like it", Raph answered. "I hope Donnie wakes up soon" Mikey said. He looked sad. "Don't worry, Mikey", Leo said, "I'm sure he'll be fine. Why don't you prepare some soup for when he wakes up?" "Okay" Mikey said and he left the lab. Leo looked at Donnie. "You don't think he's gonna wake up any time soon, do ya?" Raph asked. "I dunno", Leo said, "Hard to tell without Donnie." "Come on, fearless. Let's make sure Mikey is okay." Leo let Raph take him away. Mikey was in the kitchen searching for a big pan to put the soup in, but he was so upset that when he found one, he accidently dropped it. He couldn't hold the tears back anymore and he fell on his knees. Raph ran to him and gave him a hug. "He isn't gonna wake up, is he?" Mikey asked crying. "Of course he is gonna wake up. It'll just take some time, that's all" Raph said giving his little brother another hug. "Come on. Let's watch some TV." Raph and Mikey sat down on the couch and turned on the TV. Leo looked at them. "I hope Donnie will wake up soon", he thought, "For all of us."
