Raikou (Japanese: ライコウ Raikou) is an Electric-type legendary Pokémon. It is not known to evolve into or from any other Pokémon.
Along with Entei and Suicune, it is one of the legendary beasts created by Ho-Oh after the burning of the Brass Tower. Of the three legendary beasts, Raikou is said to represent the lightning strike which ignited the fire that consumed the Brass Tower.
Raikou is a yellow tiger-like creature with black stripes that resemble lightning bolts and a white under-side. Raikou has a skinny, light-blue tail with an electric spark-shaped formation at the end. Raikou appears to have a grayish-purple cape that is supposedly made of thunderclouds. Most of Raikou's face is white with a light-blue "X" on its face and a gray crest on its forehead. Raikou has red eyes and long fangs in its upper jaws that make its appearance similar to the sabre-tooth cat.
