Entei

Entei is a Fire-type Pokémon from the Pokémon series. It is a legendary Pokémon native to the Johto region, and is part of the Legendary Beasts along with Raikou and Suicune. It appears at #244 in both the Johto and National Pokédex.

Entei was originally one of three Pokémon, along with Raikou and Suicune, who perished to its death when the Burned Tower (then known as the Brass Tower) mysteriously burned down 150 years ago. After the fire was extinguished, the three Pokémon were resurrected by the legendary Pokémon Ho-oh into their current forms. It is said that Entei's barks are powerful enough to cause volcanoes to erupt. It races across the land in an effort to exhaust its unrestrained power.

In M.U.G.E.N, Entei was made by Otto under the name "Yuiitusin".
