Donarion

Sun: It zips around, on sharp lookout for an opening. It concentrates electrical energy within its large jaws and uses it to zap its enemies.

Moon: It produces electricity via an electrical organ in its abdomen. It overwhelms bird Pokémon with shocking beams of electrical energy.

Ultra Sun: It has an organ that generates electricity in its abdomen. It concentrates energy in its strong jaws and fires off powerful jolts of electricity.

Ultra Moon: Vikavolt flusters opponents with acrobatic flying maneuvers. This creates an opening for it to deliver an electric beam attack.

Sword: It builds up electricity in its abdomen, focuses it through its jaws, and then fires the electricity off in concentrated beams.

Shield: If it carries a Charjabug to use as a spare battery, a flying Vikavolt can rapidly fire high-powered beams of electricity.
