Voltorb are spherical Pokémon with no arms or legs. They look like a Poké Ball with a face, minus the button; their top half is red, while their bottom half is white. They were first seen in the plant where modern Poké Balls were invented. Voltorb and their evolution, Electrode, could be forms of energy, but it is unknown where that energy came from or how it created them. Because of the similarities with the Poké Ball, it has been suggested that Voltorb are artificial Pokémon, created with some form of human involvement.
Voltorb are easily agitated, and are known to self-destruct due to anger.
Voltorb are generally found in power plants and other areas with electric fields, and due to their volatile temper and habit of exploding out of anger are generally considered pests. They are also found on farms guarding the crops and fruit there, and are usually painted the same color as the fruits they guard. It is common in Kanto and Johto.
This Pokémon was unavailable prior to Generation I.
