This Voltorb is an electric-type Pokémon owned by Jet.
Jet registered his Voltorb, Oddish and Dodrio for the speed course. Voltorb was used in the Hurdle Dash where it was easily able to outspeed Gold's Sudowoodo. Voltorb was the first Pokémon Jet used in the Relay Run. It was shown to be fast, easily getting a huge lead in the race. Voltorb was later switched for Oddish.
None of Voltorb's moves are known.
