Mars

His name is Mars. When he was born, he was actually pretty small and almost didn't survive. While he was growing up, others would tease him for his little stubby horn that was barely a horn at all, how weak it would be compared to the others. They also made fun of how weird his vapor glowed, how unnatural it was and how Mars never would fit in because of it. Though despite all that, Mars was determined to be strong, and eventually grew up to become a brute, and his horn became curved and sharp, his vapor putting fear and awe into others. He's very protective of his family and friends, and when dueling others with his horn, it's as if he dances and effortlessly defeats others with it's curve. His dominating ability is speed. He has a kind and loving heart, but can sometimes break into rage when his friends or families get hurt or picked on, or when others anger him. In his highest rage state, it's very hard to calm him down and can be dangerous and unpredictable, often he doesn't realize the damage he causes until his anger subsides and he returns to a calm state. But that's common for Fumi's with glowing vapor, and there's not much he can do about it. Others fear him for it, but he really is kind at heart and wants the best for his family and friends.
