Piper

Piper (voiced by Chiara Zanni) is the 14-year-old navigation and tactics specialist of the Storm Hawks. She's also a crystal specialist, capable of refining raw crystals into usable ones, an art considered difficult at best; "Crystal Mage" is the official term. Piper often devises elaborate plans for the team to follow, though more often than not they only manage to complete part of the plan before simply improvising, annoying her, but consistently puts up with it because of their friendships with her. She is very opinionated, often to the displeasure of her teammates, and will freely speak her mind.

Despite her more intelligence-oriented station, Piper is a capable fighter. She is a master of a unique style of martial arts called "Sky Fu" (the Storm Hawks' equivalent of Kung Fu) and her knowledge of crystals make her attacks in battle unpredictable, since her crystal-powered staff could potentially have one of any number of effects. She was able to maintain a steady battle against Master Cyclonis by herself, eventually forcing Cyclonis to retreat by breaking the crystal on her staff. She also fought Cyclonis in "The Masked Masher", successfully fending off her attack and remarking that Cyclonis "fights like a girl." Piper later discovers that she has a strange ability to imbue the power of crystal within Aerrow, later to be called "The Binding". The untrained power weakens her considerably at first, but she is restored to health when she and Aerrow come into "perfect attunement", something even Cyclonis herself is not capable of.
