- Solgaleo can turn Sunsteel Strike into a Z-Move known as
Sunshine Smasher
in Japanese. It can also be used by Dusk Mane Necrozma. - Lunala can turn Moongeist Beam into a Z-Move known as
Moonlight Blaster
in Japanese. It can also be used by Dawn Wings Necrozma. - Necrozma (and its forms) can also learn a new move, known as
Photon Geyser
in Japanese. It's a Psychic-type Special move.
Both moves appear to deal huge damage and bypass abilities. CoroCoro also states that the Rotom Dex can be upgraded during the game to allows certain features like Pokémon gaining more EXP and using Z-Moves more than once.
