It is not known to evolve into or from any other Pokémon.
Along with Raikou and Entei, it is one of the Legendary beasts resurrected by Ho-Oh after the burning of the Brass Tower. Of the three Legendary beasts, Suicune is said to represent the rains that quenched the flames of the burning Brass Tower.
Suicune is a slim, quadrupedal, blue, mammalian Pokémon with white stripes and dark blue markings. Suicune has a thick, blue mane and a blue tail. It has purple eyes, a long snout and ears with purple on the inside. Suicune has a Small blue sphere in its mane with another larger one on its tail.
Suicune has the power to walk across water and purify dirty water with one touch. It travels across grasslands in search of water to purify by following the north wind. Northern winds always seem to blow stronger in its presence. In Pokémon Crystal, Suicune is said to be the closest of the Legendary beasts to Ho-Oh. It is also said to have a link to the Unown. In the anime, Suicune is heroic, serious, and calm during dangerous situations. Suicune is believed to be both the embodiment of the north winds and compassion of pure spring waters.
Suicune made its debut in Don't Touch That 'dile, where Ash and his friends first encountered one as they were heading towards New Bark Town. Suicune was seen standing on a small island in a lake, appearing as a mysterious silhouette of blue energy. At first, Ash did not understand what Pokémon it was and wanted to catch it. However, Suicune leaped into the fog and vanished as soon as Ash made an attempt to battle it.
