Nintendo latest Direct live stream revealed some details about Pokemon Ultra Sun and Ultra Moon. As expected, the game’s story will revolve around Necrozma, who will capture either Solgaleo or Lunala (depending on your version) to form new variations of the Prism Pokemon, similar to what went down in Black and White 2.
The new variations of Necrozma are called Dusk Mane Necrozma, and Dawn Wings Necrozma (Solgaleo and Lunala respectively) and each game will also get an all-new Ultra Beast. Ultra Sun will get UB Burst while Ultra Moon gets UB Assembly. Both new Ultra Beasts are just as funky and borderline nonsensical in their design, but they promise to add new strategy to battle.
Also for Pokemon trainers who purchase the eShop re-releases of Gold and Silver will get a free Celebi to port into Ultra Sun and Ultra Moon, so look out for that as well.
