  • This move was created for Pokémon Uranium

Expunge is an offensive Nuclear-type move introduced in Pokémon Uranium. It is the signature move of Hazma, though other Pokémon may call it using Nature Power in irradiated areas.

Unlike most Nuclear-type moves, Expunge is super-effective against Nuclear-type Pokémon. Its accuracy increases to 100% during Nuclear Fallout. It can also be used to purify corrupted Nuclear Pokemon.
