Hey, people, and welcome to another new story, this time it's something different. This story was requested by retro mania, and while I usually don't do requests (haven't gotten anyone before), I found his idea interesting and began working on it, and here is the first chapter.

This story takes place in the old 1980's cartoon, not the 2003 that I usually work with. Let's hope that you all enjoy it all the same, and that I can do everything justice.

Mona Lisa's Humanity

Chapter 1

Chemicals

A month had passed since the incident with captain Filch, the masquerade on the cruiser and the Turtles meeting the salamander mutant, Mona Lisa, and since then, the female mutant had moved in with Splinter and the Turtles, becoming a family member. While living in the sewers wasn't something that she had expected herself to do, it was far better than she would ever had thought, she got her own room and everything, and that was a lot better than how her life had been after her mutation. It certainly didn't hurt that she got to be close to Raphael, he was quite cute after all, and he had made it clear the he thought the same about her, because of this, the two mutants grew to be pretty close friends.

But there was one thing that hindered Mona Lisa from truly enjoying her new life, she still missed her family and friends from her old life. While she was focused on stopping Filch from taking over the world, she didn't have time to truly think about what she had lost, but now that Filch was behind bars, she remembered how much she missed everyone she knew and that she may never see them again. And even if she did meet them again, she wasn't human any longer, and they would most likely be afraid of her.

Her state didn't pass the other mutants by, and they tried their best to keep her spirits up, one more than the others.

Donatello sat in his lab, working with various chemicals, carefully adding a few drops of one chemical to another, watching as the mixture changed colour from red to purple with instances of blue and green.

"Okay… and if I add some-"

"Hey! Donatello! What's up, dude?" Michelangelo almost yelled as he entered the lab.

"Don't do that, Michelangelo! I'm working on some serious sensitive stuff here! The tiniest mistake and it might go kablooie!"

"Sorry, dude. So what is it? It looks mondo cool."

"I'm working on a retro-mutagen for Mona Lisa, so she can be human again."

"Wow, that's outrageous. But why would you wanna turn the little dudette human?"

"Because she misses her family, Michelangelo, her human family. We have all tried to make her feel better, make her feel at home here, but I want to really help her be happy again, and I know making her human again would go a long way, but it's very difficult."

"Why is that, amigo? You did the same for master Splinter once."

"Yes, and it only lasted for a couple of hours, that's one of the things that I need to work with. But the real problem is that Mona Lisa was mutated by radiation, not mutagen like master Splinter and us, so I got my work cut out for me."

"That's some heavy stuff."

"No kidding, but I think I might be on to something. Fetch me the nitro-chlorine."

"The what…?"

"The pink stuff on the shelf, up to the right."

"Coming right up, compadre."

On an asteroid in a distant part of Dimension X, the Technodrome sat stranded without enough power to move anywhere. But the inhabitants were planing to try and change that.

Again.

"Shredder! Get over here!" the brain-like alien yelled from the stomach compartment of his android body.

"What is it now, Krang? Is there a sale on the home-shopping channel?" Shredder asked with a mocking voice.

"Oh, very funny. Did you think that out all by yourself, or did you have to enlist the help of those bumbling mutants of yours?" Krang replied dryly. "I have been monitoring Earth, and have discovered a new power source. The humans have been developing a new super fuel, precisely what we need, and you are going to Earth to steal it."

"And where on Earth is this fuel? Antarctica? The Amazons?"

"New York City. And you have to retrieve it from several different laboratories, since they have developed the different ingredients in separate locations, then you have to use another laboratory to mix them together."

"Why can't we just bring them all here in the first place?"

"Because, you simpleton, several of the ingredients are too sensitive to be transported through the dimensional portal without the risk of exploding upon arrival. Mixing them will make them stable, and I also want you to add one extra chemical to the mixture, that will increase the potency of the fuel a hundredfold. One vat will be more than enough to power up the Technodrome-"

"...so that we can transport it back to Earth and conquer it." Shredder filled in. "Bebop! Rocksteady! Get over here on the double!"

Shortly after, two mutants came running, one rhinoceros and one warthog.

"Eh, you called, boss?" Rocksteady the rhinoceros asked.

"No, I was just warming up my vocal cords for a song."

"Oh. Can I make a request?" asked Bebop the warthog.

"No, you blister brains! We're going to Earth, so get your act together, you mutant morons!"

"I would still have liked a song." said Bebop.

While Shredder and his mutant goons travelled to Earth and began their tour of pillaging the various labs and factories, the turtles were hot on their trail, but never managed to catch or even prevent them from stealing the chemicals. And for as hard as the turtles looked, they weren't able to find where the villains were hiding.

"Shredder has been raiding chemicals for almost a week now, and we still haven't been able to find him. I wonder just what he's up to." said Leonardo as the turtles drove the Party Wagon through the streets of New York.

"No good as usual." said Donatello. "I bet they are trying to make some kind of super fuel for the Technodrome, I can't believe that the area of Dimension X they're in has a lot of energy sources for them to use, or they would have been back a long time ago."

"No matter what dimension, there are always some places where you can never find a gas station." said Raphael.

"Guess we'll just have to wait until he strikes again, and hope we get luckier, but for now, let's head home." said Leonardo.

"Sounds good to me, then I can continue working on the anti-mutagen for Mona Lisa." said Donatello.

"Do you really think that you can make her human again?" asked Raphael.

"I do, and I think I am on the verge of a breakthrough, if all goes well, it will be ready tomorrow."

Raphael was happy to hear that they could help Mona Lisa, but he also felt sad that she might leave them, and him specifically. Would the anti-mutagen really work?

And that does it for the first chapter. I must say, writing in the more cartoony style of the 1980's show was a new experience, but still rather fun, though there were times where I almost fell back the 2003 style, have to keep an eye on that.

Still, I hope that you all liked it, and next time we'll see if Donatello really can turn Mona Lisa human again.
