Necrozma has split into dusk and dawn versions. Details about these mysterious beings will be unveiled later. This is the new-model 2DS, not the original version. In Pokemon Ultra Sun, it will know the move Fire Fang, while in Pokemon Ultra Moon, it will know the move Thunder Fang. Not much else is known about them. Oh, and if you're in Japan, you get arguably the better option: A Pikachu edition of the 2DS XL instead. The new design launches November 3. The special Rockruff that evolves into Dusk Form Lycanroc is given to players who buy Pokemon Ultra Sun and Moon by January 10, 2018. Special themes for each game will also be available for fans who purchase Pokemon Gold Version or Pokemon Silver Version by January 15.
If you purchase either one of the virtual console releases of Pokemon Gold and Silver on the 3DS, you can get a Celebi for Pokemon Sun & Moon or Pokemon Ultra Sun & Moon. The new portable will be available on November 3rd, just a few weeks before the latest Pokémon games hit the handheld on November 17th.
