An upgrade to the Rotom Pokédex adds Roto-Loto, which allows the player to use boosts, akin to O-Powers from the previous generation and Z-Rotom Power, which allows players to use up to two Z-Moves per battle.Pokémon Ultra Sun (ポケットモンスター ウルトラサン Poketto Monsutā Urutora San) are role-playing video games developed by Game Freak, published by The Pokémon Company, and distributed by Nintendo for Nintendo 3DS. New Z-Moves are available for multiple Pokémon, including Solgaleo, Lunala, Lycanroc, Mimikyu and Necrozma. Three new activities have been added: Mantine Surf, which allows the player to surf across the region's seas-it also serves as an alternate way of earning Battle Points Alola Photo Club, which allows players to take pictures of their player character with Pokémon in various poses and Ultra Warp Ride, which allows the player to travel through varying Ultra Wormholes and encounter Ultra Beasts in their own worlds-in addition to finding legendary Pokémon from every game in the series, up to three times, and an increased chance for shiny Pokémon to appear. Players can now travel around the Alola region to collect Totem Stickers, which allow the player to receive a Totem-sized variant of a Pokémon. Also, a new Lycanroc form was added, Dusk Lycanroc. In addition, there are new forms for the legendary Pokémon Necrozma, dubbed "Dusk Mane" and "Dawn Wings" forms, which are achieved by absorbing the legendary Pokémon Solgaleo and Lunala, respectively it is conceptually similar to Black and White Kyurem from Black 2 and White 2 and Lusamine's mutated form from the original Sun and Moon. Ultra Sun and Ultra Moon introduce new Ultra Beasts: Stakataka, Blacephalon, Poipole and its evolution, Naganadel.
