I love these two Unikitty Characters so much I made them TMNT Characters!
Hawkeye Dillan, as a young teen, trained with his brother Eagleclaw under their sensei to become martial arts action heroes. He trained with his brother hard, and they both became great martial arts action heroes. At the end of their training, their sense would bestow the greatest honor: cool sunglasses, symbolizing the right to be the next sensei. But only one was to earn those sunglasses and sensei title that day, and he sensei gave them to Hawkeye. Eagleclaw, mad with jealousy, began to attack everybody and everything in the dojo, screaming that those shades and sensei title belonged to him. Nobody could stop him, not even the sensei, but Hawkeye could. After driving off the bitter Eagleclaw who vowed to return for a rematch, Hawkeye left the ruined dojo and his beloved sensei, swearing to protect the world from people like his brother. Along the way, he encountered the Ninja Turtles, and aided them agaisnt Shredder's minions. He ended up captured by Stockman, who planned to try to use his skills for evil, and mutated him using DNA from both a Hawk and a crocodile, earning him the new name Hawkodile. But thanks to the Turtles, he managed to escape before they could take his mind. He became a regular ally to the Turtles. When Karai became good and decided to try to rebuild the Foot Clan and bring honor back to it, He took a job with her as her bodyguard.
Dr Della Foxglove is a brilliant young mind who was a child prodigy in many sciendces from biology, robotics and quantum physics. She was a scientist who was once captured by the KRaang to help perfect the mutagen. She was rescued by the Ninja Turtles, but not before she got mutated into a fox, where she recieved the name of Dr Fox by Michelangelo. She became a regular ally of the turtles. When Karai became good and decided to try to rebuild the Foot Clan and bring honor back to it, Dr Fox took a job with her as her best scientific mind and strategy-planner.
Hawkodile had an obvious crush on Dr Fox, though she was unawares, because instead of telling her, he'd punch his feelings away because he was out of touch with his emotions. IT wasn't until he developed a condition when his bottled-up emotions reacted with the mutagen in him that caused him to literally shrink under the weight of his crush and he kept getting smaller and smaller until he could confess his crush that he finally decided to tell her how he feels, and they became a couple. They became an ultimate team of Brains and Brawn.
