Dedenne is a small, round, orange mouse-like Pokémon, whose whiskers are in shape of antennas, which it uses to communicate with far-off allies. It has orange pouches on its cheeks that charge electricity, and its belly is a pale yellow. It has round black ears with light yellow insides, and a long black tail with a star-like tip. It has an aradicular tooth that can be seen on its upper jaw. Its tail can absorb electricity from power plants or house outlets. It can then fire electricity from its whiskers.
