Electricity has long been known to man, for the multitudes of electric pokemon have coexisted with its ancestors throughout the history of evolution. Yet before the development of modern electric currents, the supply these pokemon produced was too intermittent to have a use outside of battle and lighting. The great exception to this is Luxio, whose electric-charged claws have enlivened Sinnoh's festivals for centuries.
Most electric pokemon produce a bright yellow electricity, which can grow painful to the eyes over extended periods, and produce it through cheeks, tails, or other body parts where they lack precise control, but Luxio produce a blue lightning, more pleasing to the eyes. This electricity gives Luxio fur its light blue color, although an old belief persists that the black portions of their fur are the result of burns from their internal electric current, and that blue is its natural color. This lightning is most commonly used to light up the eyes or fists of large statues in a blue glow, and to bring them to life, opening doors and smashing rocks as their body sparks with Luxio energy.
In Egypt, this was the origin of the great Sphinx, a statue half-Luxio, half-man, no longer operational and covered in desert sand. In Sinnoh, the statues themselves are mostly lost, but this sight is amply recorded in its histories, and the art developed with Luxio animation is believed to be either the direct predecessor of or the inspiration for the great golems of Mount Coronet.
Soon after man learned to control electricity, they were inspired by the Luxio to bring not statues, but drawings to life. Many early works of animation, such as the shiny title character of Jungle Emperor Xio, paid tribute to these mighty pokemon.
