Disclaimer: I don't own anything, just the oc. Also, Morphagen was my very first oc that I created.

It happened randomly. It was just an average night. Nothing cause it to happen whatsoever. But it did happen. Whether it be fate or just a random occurrence, that's completely up to one's opinion. On one normal night, something abnormal happened. In the kraang building, an average batch of mutagen glowed.

It glowed brightly, much brighter than any other canister. Then there was a shatter as it broke out of the container it was held in. It fell onto the floor and began to take form. It became almost humanoid, growing legs and arms, fingers, and a head. The body it formed almost looked like one of the ninja turtles. But not quite, it didn't have a turtle shell.

It's hands had five fingers on each hand. But it's feet were more like shoes, no toes whatsoever. The mutagen swirled inside it's body, like a clear balloon filled with liquid. It's eyes were normal, but it's irises were gray, colorless. It didn't have a nose or ears, but it's mouth was normal. It had perfect pearly white teeth, but it's tongue was the same greenish color as the mutagen.

And so it happened, mutagen itself has mutated. There was now a creature that was living mutagen. The ooze that mutated the turtles and Splinter and every mutant, spontaneously mutated itself.

When the mutagen creature's mutation was complete, it didn't take long for the Shredder to get it in his possession. This creature intrigued him. He wondered what it was capable of. And how he can use it against the turtles.

Shredder circled around the ooze creature, looking it over. Then stopped in front of it. "I am the Shredder, creature. And I own you now. Do you understand what I say?" He asked. He had a collar put around the creature's neck. And pushed a button that was in his hand. The creature flinched in pain and grabbed at the collar as electricity course through it's body.

The creature looked up at him into his eyes for a moment when it was done, then looked away. "Y-Yes, I understand." It spoke softly. The man in front of him scared the mutant greatly.

"That's good. Now, do you know what you are?" Shredder then asked. The mutant creature gave a quick nod.

"Yes. I am mutagen, or ooze, that mutated. Now I am alive." It said. The mutagen creature didn't know why it knew what it was and what it could do. But it just did.

"So tell me then, what are you capable of? What can you do?" Shredder asked. Even though it was a question, to the mutant, it didn't sound like a question. It sounded like an order.

The mutagen creature looked up at Shredder again. "I'm not sure how to explain it. But I can show you if you let me touch you." It said, bringing up and hand to touch Shredder, but not moving to yet.

"So be it. You may." Shredder gave permission. Then the ooze mutant took the few steps to touch Shredder.

It's skin felt weird. It was like a person's skin, soft and smooth. But also like holding water balloon. It was a weird cross between the two. Like nothing there ever was before. But it was only for a second and the creature brought his hand back.

Then it took a step back and closed it's eyes, focusing. It glowed as it's body changed. And soon the creature became the Shredder himself. It looked at the real Shredder, waiting for his reaction.

"Interesting. But is it just an illusion? Like a hologram." Shredder asked.

"No. I have become you now. And I know all of your skills and abilities." The morphed Shredder said, in Shredder's voice as well.

"We'll see about that." The real Shredder said right before he attacked. The two fought but it didn't last long. Shredder quickly saw that the creature spoke the truth. It did obtain his abilities. The morphing creature turned back into it's true form when it was done.

"Congratulations creature. I do in fact have use of you. With your ability you're going to help me hunt down my enemies. After much practice, you will eliminate my enemies, the turtles. And then you will bring Hamato Yoshi, Splinter, to me. Am I understood?" Shredder said.

The mutant looked up at him with a distraught look. "But, I don't want to-" He was saying but was cut off as Shredder pushed the button once again. The mutagen creature grabbed it's collar again. It let out a sound of it's pain as it fell onto it's knees.

"You will do as I say. And you will call me Master Shredder. Am I understood?" Shredder said, more stern this time. He then stopped the shock collar.

"Y-Yes Master Shredder. I will do what you say." It said as it kept it's head lowered.

"That's a good mutant. Now get up. You're training starts right away." Shredder said as he turned and began walking away.

And train the little mutant did. And after a while, the plan was set and ready. The mutagen mutant was going to infiltrate the turtles lair and eliminate them as them. Then it will trick Splinter and bring him here to Shredder. A simple plan really. There was no room for mistakes.

One night, a seemingly regular bird flew over head and landed on a rooftop. Then a cat scurried down a fire escape and into an alleyway. Then a rat squeezed through a grate and into the underground below. Then there was a cockroach scurrying its way across the wall.

The turtles were in the lair, go about their normal day. It was just after training, so they were taking time to relax a bit. The genius turtle of the group, Donatello, was in his lab. The ever workaholic typed away at his computer, drawing up blueprints, and did experiments. The usual stuff for him.

"Hmm?" Donnie noticed a roach on his desk as he worked. He smiled as he moved his finger so that the roach could climb onto it.

"Hello there little guy. Interested in what I'm doing? It's nothing much really. Just upgrading the t-phone. I'm thinking of making it a bit sleeker in design. I don't really have use right now for a spy-roach. So you can scurry off now." Donnie said to the roach and let it off his finger. "But make sure to not let Raph see you." He added.

The roach then disappeared and a rat made it's way to the kitchen area. Mikey was in the kitchen making a, what he calls a "snack". The rat climbed up onto the table and made a squeak. Mikey turned when he heard the sound and smiled at the rat.

"Aww. Hey cuddly buddy. You must be hungry." Mikey said. Then he got a cheese-sickle from the freezer and broke off a piece. He gave it to the rat and then petted it. It started eating the little piece of frozen cheese.

"Just don't get a brain freeze little guy. Wait... can rats get brain freezes?" Mikey wondered. Then he shrugged and let it go for now. The rat scurried off with the piece in its mouth and disappeared. Mikey went back to making his "snack".

The rat scurried through the lair, running over Raph's foot. Raph freaked a bit when he felt it, thinking it was a cockroach. But deadpanned when he saw it was a rat. The rat looked at him, it's nose twitching and the piece of cheese in it's mouth. Raph got annoyed when he saw it.

"Mikey! Stop feeding the sewers rats! If you keep feeding them, they'll keep coming back! And then we'll never get them to leave." Raph yelled out to Mikey, crossing his arms. The rat ran out of the lair and turned the corner so no one would see it.

The rat then glowed and turned into the mutagen mutant. It ate the piece of cheese it was given. It took this time to think. It still needed to get Leo's DNA. But how to get close to him? And then the mutant has to eliminate them. But who would work well against who? It gently touched the collar around it's neck.
