Entei

Entei is a Legendary Fire-type Pokémon first appearing in Pokémon Gold and Silver Versions. It is one of the three Legendary beasts created by Ho-Oh alongside Suicune and Raikou, and is said to represent the fire that burned down Brass Tower.

In the Super Smash Bros. series, Entei has appeared in every game since Super Smash Bros. Melee. It can be summoned out of a Poké Ball (or a Master Ball in Super Smash Bros. for Nintendo 3DS / Wii U), and when summoned it uses Fire Spin (Fire Blast in Super Smash Bros. Melee) to create a large pillar of flame around itself that damages opponents.
