Lusamine's Nihilego, Pokémon Wiki

This Nihilego is a Rock/Poison-type Pokémon owned by Lusamine. At Ultra Megalopolis, Lusamine sent Nihilego. As she wept at something being taken away from her, she embraced Nihilego, calling it as "her child", and fused with it. None of Nihilego's moves are known.
