New information has been leaked through CoroCoro about the new forms for Necrozma. It confirms that they are fusions of Necrozma and the other legendary saying that Necrozma absorbs the other. It's Solgaleo form is called Necrozma Mane of Twilight and it's Lunala form is called Necrozma Wings of Dawn. (Potential Lycanroc Dawn form?) It is also said that the new forms have Sunsteel Strike and Moongeist Beam respectively.
Over-dramatic much, Pokémon? Wings of Dawn? Mane of Twilight? This is not a freaking ROMANTIC MOVIE, alright?! I really hope Dawn is revealed. Even if that's just my OCD chanting 'must have equal dogs must have equal dogs'. #MissingNo
I was really hoping that Solgaleo and Lunala would absorb Necrozma (or possibly be wearing it as armor) and not the other way around.
Aww man. Then I take it Nebby is going to be absorbed by Necrozma. Poor Lillie...she's going to be devastated.
So it seems that Necrozma is the Alolan version of Kyurem. Interesting to see how this will play out. Necrozma isn't an ultra beast, so maybe that's why it is the third main legendary for the region. It kind of reminds me of that Deoxys black triangle from Birth Island... Spoiler
Japanese is always more dramatic in naming conventions. I am really not surprised by it, but I do like it.
