Dawn Wings Necrozma

As the storyline of Pokemon Ultra Moon progresses, Lusamine, the head of the Aether Foundation, will desire to open an Ultra Wormhole in order to stop Necrozma. After doing that exact thing with the help of Nebby, it will be up to your player to ultimately stop Necrozma once and for all. However, as you go to restore Nebby at the Altar of the Moone, Necrozma will open an Ultra Wormhole and fuse with Nebby, thus turning into its Dawn Wings Form. It is here that you will first battle Necrozma; however, you won't be able to capture it just yet.

While in its Dawn Wings Form, Necrozma will be a Psychic/Ghost Type Pokemon with the ability of Prism Armor. In this given battle, it will be at Level 55 and know the moves Moongeist Beam, Moonlight, Psychic, and Power Gem.
