Crystal's story starts out about as normally as any pokemon trainer's story would start out, young, adventurous, and filled with the determination to see what the wide open world has to offer. However she never would have guessed she'd end up as a legendary pokemon at any point, no less that she ended up that way by the good graces of the legendary Ho-oh only shortly after capturing Suicune herself. She now lives her life as the adopted child of Suicune and whenever she isn't out swiftly running at surprising speeds to purify bodies of water as her mother would she is simply resting in her well hidden den which is home to quite possibly some of the most clean and pure water in the world.
