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 cream-colored 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.
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. Vaporeon can also glide in the air for moments because of its fins.
Vaporeon are very difficult to observe in the wild, as they are quite rare. 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. It is found in the same regions that Eevee can be found in.
