Character: Suicune

Suicune is one of the three "Legendary Beasts" that are featured in Pokémon Gold, Silver, and Crystal. According to legend, the Legendary Beasts were reincarnated by Ho-Oh from the spirits of three Pokémon which died in the fire that gave Burnt Tower its name. They are awakened in this tower in their first video game appearance. It is the incarnation of northern winds, which always blow as it passes throughout the world. It also embodies the compassion of a spring, so as it travels, it seeks out pure reservoirs of water, and using its power, it instantly purifies dirty, muddy, or otherwise polluted water into the clearest of liquids by simply stepping into it.

In Pokémon Crystal Suicune is the star Pokémon, in a similar way that Pokémon Gold showcased Ho-oh or Pokémon Silver showcased Lugia. Eusine, a mysterious trainer, appears throughout the course of the game. He is set on meeting and catching Suicune, and will battle the player for that honor. Eventually, Suicune can be caught by heading to the Tin Tower after obtaining the Clear Bell. Three old men will challenge the player to a battle and if they are defeated, they will allow access to a floor where Suicune waits to battle.

Suicune makes various appearances in the anime, mainly appearing before Ash and his friends. It is featured in various episodes, and it plays a role in the movie, Pokémon 4Ever.
