It is quite curious, given its height, that the only birds found in the Vast Poni Canyon are the nocturnal Murkrow and the thickly armored Skarmory; Alola as a whole teems with birds, and the canyon is most easily accessible from the air. Curious, that is, until one learns of one of the canyon's rarest pokemon, an evolution of Charjabug spurred on by its magnetic field: the deadly Vikavolt, the terror of the skies.
Many a Kahuna of Poni Island was frustrated by raids from the bandits who called the Vast Poni Canyon home and sought to subjugate them once and for all, but the canyon's narrow walls could be barricaded by even a couple competent pokemon trainers. But Alolan warfare, like that elsewhere in the world, relied heavily on flying pokemon to survey and bombard the battlefield – and the canyon's outlaw settlements relied as much on the open air clearings as it did its caves. Generations of Kahunas sought to fly their Toucannon and Oricorio above the canyon's walls to seize it from the air, the later ones against the advice of their advisors. The advisors were right, for whenever they tried, a bunch of Vikavolt would inevitably zap whole fleets out of the sky.
Even in modern times, Vikavolt are considered a symbol of Poni Island; not the Poni of the Kahunas, some kind of orderly mirror image of the rest of Alola, but a symbol of the wild and free land which Melemele, Akala, and Ula'ula could never hope to emulate. Even today, Vikavolt play a key part in keeping Poni Island wilderness – most recently, by snapping an attempt to string power lines to its remote villages in order to supercharge themselves!
