Vaporeon :
It is not a legendary pokemon. Vaporeon is a Water-type Pokémon introduced in Generation I. It is the Water-type evolution of Eevee.
Vaporeon shares physical traits with aquatic animals and land creatures in appearance. Vaporeon's body is light-blue with a white ruff around its neck. Vaporeon has cream-yellowish ears-like fins made of webbing on both sides of its head along with a third on the top. Vaporeon has blue ridges that run down the length of its spine and on to its tail-fin. The tail resembles that of a fish.
Vaporeon's molecular structure is close to water, and its body glitters when sunlight hits at certain angles because of it. It has a graceful, slender body shape, further adapting it to aquatic regions so it could swim faster. Its face is feline in structure, with a short muzzle and a small, triangular nose. Vaporeon is the result of an Eevee's exposure to the radiation of a Water Stone.
