Thunderstorm is an Electric-type status move introduced in Pokémon Uranium. It causes a Thunderstorm for five turns, dealing damage to all Pokémon except Electric- and Ground-types. Thunderstorm is the signature move of the Volchik line.
It is one of the only ways to summon the Thunderstorm weather condition, the other being Yatagaryu's Stormbringer ability.
