So two things, the character of Kevin does take some inspiration from the character of Jet from Avatar the Last Airbender but set up to be even more tragic, Kevin is like Jet with all of Jet's nobler traits stripped away, while obviously I don't want to spoil what's going to happen, Kevin's story will end very differently from Jet's but I do try to emphasize it really is a tradgedy because in his story in Fictionpress I show Kevin as a Kitten really was a lot like Marzipan, he seemed to have a bit of 'imagination magic' maybe not to the same extent as Marzipan, but he would entertain himself by going on whimsical imaginary adventures inspired by the toys in his room, but unfortunatly Kevin's Mom was a bit of a 'Karen' and she most likely passed on her 'spoiled brat' values to her Son.

Down deep, in one of the secret hiding places the 'Runners' used, a hidden room in the underground between the surface and the Downdeep-Downdeep, a group of the Supply Runners led by Kevin Felidae, once an ordinary Cat-Boy from the affluent Mizzer town of Dahlia, now he was a miserable Bank Cashier on Viola Strierra, he and his fellow Suplly Runners made use of the fact they worked in the fancy parts of Capitol City to smuggle food and other supplies to the fugitives hiding the even deeper forgotten places under the city, very dangerous work because if they got caught the Wranglers would not hesitate to make sausages out of them!

Kevin was so good he was seen as a leader among the runners, even born and bred Native Humanimals of Viola Strierra were led by him, they admired the Black Cat's wit and cunning!

But at the moment, they watched as the Black Cat paced back and forth like a big cat at the zoo, his tail lashing in agitation! Just a few minutes ago he had met Ichabod, and when he learned he was Marzipan's fiance the Cat-Girl that Thespian Cat Gus Cheshire had been speaking so fondly of and had promised to indroduce Kevin to his her as he had been impressed how how well Kevin's bringing of supplies had taken care of his sister and her family, but also when he learned about Kevin's past on Mizzer and he he had made up imaginary adventures as a Kitten he remarked on how Marzipan so often did the same, so much so it was clear she preferred to live in her own imaginary world rather than the dull, boring world of homework and chores "You two would be perfect for each other..." Gus said just before he left.

Now of course Kevin had never met Marzipan. He had only heard about her, and he had no idea what her adventures had been so of course it was only logical she might have already found someone over the course of her own adventures...But to learn that this Cat-Girl that he had been told was so much like him, had not only fallen for a human, which over the course of his enslavement, Kevin had come to see as the lowest form of life, but such a scrawny, homely one at that! With a bulbous nose like a turnip and such scrawny, splindly arms and legs upon looking at him the words Kevin immediately thought were 'Anemic' and 'Are they even feeding you?' if Kevin wasn't such a city boy, even before coming to Capitol City his hometown of Dahlia was basically Mizzer's equivilent of Beverly Hills he might have thought Ichabod looked like a Scarecrow as the Native Children of Planet Alderbaren who knew about the history of the Arkham Rogues when they had been exhiled to Plnaet Alderbaren initally they mocked Ichabod by calling him 'Scarecrow's Boy' since his Father was the Scarecrow but after a while they simply called him 'Scarecrow Boy' since he looked so much like his Father he was just like a Scarecrow anyway.

"Stupid, this is stupid!" Kevin hissed to himself as he paced on all fours like an animal which on Mizzer such displays of primordial animal instincts were frowned on, but Kevin didn't care anymore because he knew back then such things were all because they were trying to impress the humans who they Mizzer Humanimals believed were always watching from afar, judging their every move, talking to the Mizzer humans revealed they had been doing no such thing, which instead of feeling relieved that the Humans didn't hate the Humanimals for not being exactly like them, Kevin just felt angry that they weren't actually all powerful gods who could have protected them from the Wranglers, really he should have been angry at his own people for building up the humans in their minds as Gods despite all evidence to the contrary but it was because Humanimals like his Mother got social power from 'the game' of striving to be the most 'human' i.e. the most ordinary, work an office job, have your nuclear family but raise your children to always be ashamed of their animal features and instincts and raise them to also get a boring office job 'the most human kind of work' tell them to never seek out fame and disgrace their family by showing off their shameful animal bodies because above all the Mizzer Humanimals took it to mean, if it makes you happy it must because it appeals to your animal instincts, therefore you should strive to be as boring as possible and be sure your life is as miserable as possible, but his Mother wasn't miserable, no as a rich housewife cat in Dahlia she was seen as a Humanimal who was as 'close to human as possible' so she found her joy in lording over her status and judging 'lesser Humanimals' but Kevin was seperated from his parents too young to ever realize this...And it was that, that was the catalyst for his deep hatred of all humans...The night of the invasion he had been captured with his friend Emrald while in the park, they came to Viola Strierra with no idea of where their parents were, eventually after much asking around Kevin finally learned some Humanimals had seen his parents, they were being sent to the Slaughterhouse for being 'unruly' if Kevin had developed a bit more wisdom over the years, he would have realized his parents doomed themselves by believing because they were rich Humanimals they were somehow exempt for the tradedy that had befallen all of Mizzer including the humans they Humanimals worshipped, their refusing to deal with the new sistuation and instead continue to act like they did on Mizzer, with his Mother yowling for her rights like she yowled for the manager at a resturant, Kevin never got around to seeing the flaws of his parents, instead in his anger and grief he blamed all humans, the Wrangler humans who killed them, and the Mizzer humans for not protecting them, and he became no different from his Mother.

It was all he could do not spit in disgust, as Ichabod began explaining his story of how they had come to liberate the Mizzerans, Kevin feighning politness had Ichabod wait in one room as he went down deeper to vent to his fellow runners.

His fellow runners, both Mizzeran and Native Viola Strierra Humanimals watched anxiously as none of them quite felt the same hatred towards humans as Kevin, and the Native Humanimals were aware of the Ancient Prophecy that told the destiny of the Humanimals, the final part of that prophecy was that the truest and purest love between a human boy and a Humanimal girl will be what liberates all of Humanimal kind at least that's the essence of the prophecy they heard, and they had a feeling, and intution deep in their animal hearts that this human boy and this Cat-Girl were very likely the pair the prophecy spoke of!

It was only Monty a young Mouse-Boy who was a Native Viola Strierra Humanimal who timidly raised a hand "Uh, Kevin I know you were probobly looking forward to meeting this Cat-Girl but if she's already spoken for...Well there are always more fish in the sea..."

And that was when Kevin leapt up and pinned Monty to the floor! Causing all the other runners to gasp as such an act of a Predator Humanimal doing that to a Prey Humanimal was such a deep violation of Humanimal Society's Predation Taboo.

"Have you forgotten why we're here?!' Kevin yowled to the pinned and squirming Mouse beneath him "The reason we're toiling in slavery while the humans enjoy the fruits of our labors?! Remember why we fight! Humans are our enemy!"

"OK! OK!" Monty squeaked "You're scaring me!"

Kevin got up and released the terrified Mouse-Boy "I'll get 'im..." Kevin said more rambling to himself than to anyone else "I'll show her! She's better off with her own kind...Yes...I know exactly how to get that human out of the way..."

The Other Runners looked at each other worried that Kevin's plans which they were now too frigtened to stop might doom all of Humanimal Kind

So originally I was going to end showing what the other three Turtles were doing but Kevin's backstory ended up taking up all of the chapter, but really when you have a character who's now evil and used to be...Not evil if not overtly good you kind of have to establish the reasons for the change, there are reasons tradgedies are longer than comdies and why villans are some of the most complex characters in fiction
