Suicune

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

In Super Smash Bros. Melee, Suicune appears as a Poké Ball Pokémon. When it is summoned, it uses Blizzard, creating an icy whirlwind around itself that freezes any nearby opponents. It returns in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U with the same role (and can appear from a Master Ball in the latter games), though it now attacks with Aurora Beam; Suicune fires a horizontal laser across the screen that heavily damages any opponents in its path.
