Voltorb is an Electric-type Pokémon from the Pokémon series. It evolves into Electrode, it and appears at #100 in the Kanto and National Pokédexes.
Voltorb are spherical Pokémon that look almost identical to Poké Balls, which unfortunate Trainers often mistake them for, only to get electrocuted. They have a short temper and will likely explode without warning.
In M.U.G.E.N, Voltorb has been made by Alexei Roschak. It uses custom sprites and attacks using moves it learns in the Pokémon games.
Voltorb is a slow character that only has three moves, excluding his Specials and Hypers. There is a glitch where it will fall below the floor, however, it can be easily fixed, as jumping will seem to get it out.
