Vaporeon is a composite creature sharing physical traits of fish, dolphins, cats, dogs, and possibly other animals. It is a quadruped with three small toes on each foot. Vaporeon's body is light blue and it has a white ruff around its neck just behind its head. Vaporeon has yellow ears made of webbing and has a fin on its head resembling its ears. Vaporeon has a pointed pattern of dark blue on its head that encompasses the backs of its ears and head-fin. It also has blue ridges that run down the length of its spine and on to its tail-fin, and the paw pads on its hind feet are dark blue like the ridges. Vaporeon's finned tail is said to look similar to that of a mermaid's. Vaporeon's molecular structure is close to water, so its body glitters when sunlight hits at certain angles.
