Entei (Japanese: エンテイ Entei) is a Fire-type legendary Pokémon. It is not known to evolve into or from any other Pokémon.
Along with Raikou and Suicune, it is one of the legendary beasts created by Ho-Oh after the burning of the Brass Tower. Out of the three beasts, Entei is said to represent the flames that burned the Brass Tower.
Entei is a massive lion-like Pokémon with some mastiff qualities. It is covered in brown fur with a long, thick mane covering its neck. It has gray plates surrounding the cape that makes it look as if smoke is coming out of a crater on its back, and a plate beneath the cream belly fur on its chest. Entei has white paws with apparently retractable claws and brown paw pads, and black cuff-like bands on its legs. It has a red face with a white plate that resembles a handlebar mustache on its face, and a three-pointed yellow crest on its forehead. Entei's head appears to resemble a kabuto, a samurai helmet.
It is said that an Entei is born whenever a new volcano appears. It is also said that whenever Entei roars, a volcano erupts somewhere in the world.
