So, similar to Beast Boy in the color aspect. Where his animals are green. I like it! Here is some information on Evalynn for better discussion on the storyline aspect:
valynn is a genetically modified human, she was a test tube baby. She was made in a laboratory in America, her sole purpose was to be a weapon that they military could use as the first and last line of defense. Ev and her sister Josephine (Josie) were made at the same facility, different departments though. Ev was made with the Elements department, while Josie was made in the animal department (she can shift into animals). Evalynn is currently 15.
Evalynn's quirk is both fire and ice. She spent the first 10 years of her life at the facility, being trained and enhancing her abilities. The facility, on the other hand, was targeted by villains and was destroyed. Evalynn and Josie barely made it out alive. That was when Lily found them (Elemental), who eventually adopted both of the girls. For the next five year, they continued training, and was able to go to school and become regular girls.
It was when they turned 15 and got the urge to want to go to the best Hero Academy they knew of, and that was UA. They got recommendations to go, but the paperwork took a full semester to process and approved in Japan. When they got approved, all three girls packed up and moved to Japan. Now, Evalynn and Josie started UA in the second semester, while Lily applied to become a teacher there.
Wow, those characters are cool! My sister, Josie, has the same animal ability as Chimera! It would be interesting to write with him. She could be fascinated with him due to his quirk and him reminding her of her sister!
