BioDamon is one of the few descendents of the People of the Vale. As a young boy, he and his mother, Juanita, travelled to the ruins of his people’s kingdom. Juanita expressed her wish that their old home would be resurrected, which inspired Damon. He searched for Victini in hopes of resurrecting his people’s old kingdom by using Victini’s power.
Damon's Sigilyph was used to control the Sword Castle while it moved in the air. It helped focus the energy from Victini to power the movements of the Sword Castle.
