Vaporeon is a Water-type Pokémon. It has a sleek, blue body with features of both aquatic and feline creatures. A distinctive light-blue ruff encircles its neck, and a fin-like crest sits atop its head. Its most notable feature is its mermaid-like tail, which helps it swim. Vaporeon's cellular structure is similar to water molecules, allowing it to melt and become invisible in water.
