A fan's no fan if they hadn't made any fan OC's. Meet my old TMNT oc, revamped and all, Black Lotus.

Inspired by the Triceratons, I made my own alien species, the Carnakai. A Reptoid sub-species, known as the most dangerous predators of the universe.
Carnakai are a savage, bloodthirsty species, wanted as the perfect soldier/assassin by all alien armies and feared for the difficulties of killing them. The skin is leathery thick, they're fast and agile and they're known for their excellent eyesight, seeing things as sound, smell and being able to see in the dark. It's their strongest point, but also their weakest. Take out their eyes and they're helpless. It's a well hidden secret among Carnakai that they're scared of water or any water-like liquid, cause that disturbs their vision. They have a second eyelid to protect their eyes and clean them non-stop to keep a perfect vision.

Lotus was bought when she was still in an egg and raised by the Triceratons to become their secret weapon in their army, but later fled to become an freelance assassin with her new partner, Mona Lisa (an actual TMNT character all fans just love to redesign. Me too).

Lotus is a very cranky, grumpy alien. She's aware of all the hate and fear towards her species (and that she's possible even the last of her kind), which makes her a cold person and hates everything too.
Until the day she got the assignment to abduct four turtles from planet Earth.

And old watchers of mine will remember her as Mikey's girlfriend.
I found it a funny idea that Mikey would be the only one who manages to befriend the most dangerous alien species and gets a romantic relationship out of it.

I took some inspiration of the velociraptors of Jurassic Park while redesigning Lotus. Including the raptor language as the Carnakai primitive language --> https://www.youtube.com/watch?v=9cCJOYn7e0w
