Vikavolt is a beetle-like Pokémon with a large pair of mandibles. Its small orange face has robotic, yellow eyes and is covered by a blue carapace. The mandibles extend from this helmet. They are blue on the inner surface and yellow on the outer surface. At the base of each mandible is a large spike and the inside is lined with short spikes. Its body is black and divided into three sections by yellow rings. The last two sections have a yellow spot on each side. On its back is a pair of wide, flat wings that are transparent with blue wing covers. It has four legs; the front pair of legs has two claws, while the back pair has only one.
Vikavolt produces electricity with an organ in its abdomen and controls it with its huge jaws to fire powerful electric beams. When it clasps a Charjabug in its legs, it is able to utilize it as an extra battery. This allows it to continue firing powerful attacks. However, during fierce aerial fights, it will release Charjabug to make itself lighter and more mobile. It is an adept flier, capable of acrobatic maneuvers such as tailspins and sharp turns. Even as it weaves through complicated tangles of branches in the forest, it is able to maintain high-speed flight. It is known to have a rivalry with Pinsir and Heracross. As shown in the anime, it likes to drink tree sap.
A Shiny Vikavolt appeared in SM119, under the ownership of Horacio, having evolved from his Charjabug at Vast Poni Canyon. It was entered in the Vikavolt race, where it went up against Sophocles's Vikavolt and other Trainers' Vikavolt, but lost.
