Heidilabuses

Arlabus, Labus—A guy with waist-length silver-white hair, usually pulled back into a high ponytail with a purple elastic band. He's 190 cm tall, has beautiful amethyst eyes, and pale skin. He wears a long black T-shirt and gray jeans with white knee-high socks and sneakers. He's kind, gentle, and often works on projects. He loves Heidi but is afraid to admit it and simply enjoys any opportunity they have to meet. He has a lean build and a narrow waist. Because of his hair and gentle nature, he's often mistaken for a girl. He also has a sister, Niki.
Heidi, a shark—a guy with short, light-brown hair that reaches his neck, often disheveled, but Labus makes comments. He's 186 cm tall and has heterochromic eyes—one red and one blue. He wears a long white T-shirt, black jeans, and combat boots, which would make him 193 cm tall. He's kind, sympathetic, and wild, and generally up for any kind of trouble. He loves Labus and barely hides it, but he doesn't say it outright. He shows affection through attentive gestures, touches, and often likes to call Labus "baby," which always confuses Labus. He has a medium build and is slightly muscular. He's a shark-human hybrid, which is why he has pointy teeth, a shark tail, and...interesting biology.
