When the Brass Tower burned, it was a sudden downpour carried by a northern wind which finally quashed the flames. Some say that it was in gratitude for this storm that Ho-oh, just reawakened, created Suicune to be god of the north wind, while others say that the spirit of the wind itself entered one of the fallen pokemon, carrying with it the power of water. Either way, what it did not bring Suicune was the power of flight, for the north wind which sweeps down upon the Johto plain is so heavy with water that wings become waterlogged and birds struggle to fly.
Suicune is called the north wind because of this legend, and because like the north wind brings pure water and blows dirt and grime out to sea, so does a simple touch of Suicune's foot turn the most toxic stream a shining blue. This fact has given it countless priests and shrines, who spend their time leading prayer and environmental cleanup efforts alike in polluted cities like Celadon and Goldenrod. Suicune does not always blow from the north, for if it did, it would reach the south pole and stop blowing. But sometimes, Suicune allows itself to be taken too far on the wind it calls home, and returns from the antarctic carrying an aurora in its fur. This is how it rests, for Suicune, unlike its siblings, fears the consequences of stopping. A walking Suicune, after all, is a slow breeze, but wind at rest is merely air and not wind at all.
Every now and then, a child's life is saved from fire by a sudden storm carried on the north wind and they grow up to chase legends.
