Vaporeon is the result of an Eevee’s exposure to the radiation of a Water Stone. Vaporeon is a composite creature sharing physical traits of dogs, cats, and fish. Vaporeon’s body is light-blue and has a white collar. 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 molecular structure is close to water, and its body glitters when sunlight hits at certain angles because of it. Because it’s molecular structure is so closely resembled to water, it can melt into water with ease, out of view from prey and predators. Many people who first see this Pokémon believe it is a mermaid.
Vaporeon are highly adapted to aquatic life. Unlike its pre-evolution, it has the ability to breathe underwater. As stated previously, they have a unique molecular structure. They have the ability to “melt” into a body of water and disappear completely from view. They can also manipulate water molecules, giving them the ability to learn Water-type attacks their previous evolution could not.
Vaporeon also have the ability to walk on water.
Because it’s a fully evolved Pokémon, Vaporeon can learn Hyper Beam and Giga Impact.
Vaporeon are very difficult to observe in the wild, as they are somewhat uncommon. When they are in the water, they are virtually impossible to see. While they are much easier to see while they are resting onshore, they possess the ability to rearrange themselves on a molecular level, causing themselves to “melt” into the water. It is likely that many mermaid stories were spawned by Vaporeon sightings, as their tails resemble those of mermaids. When Vaporeon’s fins begin to vibrate, it is said to be a sign that rain will come within a few hours.
Vaporeon are always found close to water, and prefer large, clean lakes.
Vaporeon first appeared in The Battling Eevee Brothers, under the ownership of Rainer.
Vaporeon was also seen under the ownership of one the Kimono Sisters in Trouble’s Brewing and Espeon Not Included.
An old woman named Galea owned a Vaporeon in On Olden Pond.
Ash battled against a Vaporeon in the Pokémon League entrance exam.
In Mewtwo Strikes Back, a Vaporeon owned by Fergus was one of the Pokémon that were captured and cloned by Mewtwo. The Vaporeon clone is seen again in Mewtwo Returns.
Vaporeon made a small cameo in the beginning of Giratina and the Sky Warrior together with an Eevee and the other six Eeveelutions.
Red temporarily controlled a Vaporeon, which was actually his Eevee switching between its evolved forms. It soon evolved into an Espeon, which disallowed any further switching.
