How does a fused Necrozma learn Sunsteel Strike or Moongeist Beam?

Question

(I am playing Ultra Sun and have just captured him)

I remember seeing some answers on Necrozma's moveset page that show him learning both Photon Geyser and Solgaleo/Lunala's signature moves depending on it's form. I see that Necrozma learns Photon Geyser at lv. 50, but am wondering how he obtains Sunteel Strike or Moongeist Beam. Is there a certain move he needs to have in his moveset (such as Kyurem learning Glaciate or Scary Face)? Or was I misinformed? Thanks.

Answer 1

Because Necrozma fuses with Solgaleo and Lunala, it acquires their signature moves. No, it does not need any move to acquire either Sunsteel Strike or Moongeist Beam, just needs to learn them.

To fuse Necrozma, you must use the N-Solarizer or N-Lunarizer.

Comments

Both Necrozma and Solgaleo/Lunala MUST be in your party in order to fuse them together.

Yes I'm aware of how they fuse, I was wondering what happens to Necrozma's moveset for it to obtain the move (by level up, by tutor, etc)?

It gets to learn the move instantly when it changes form.

Okay so you're just prompted to learn the move kinda like when a pokemon evolves?

No, it does it for you automatically, unless you have Necrozma with 4 moves already.
