Female necrozma

This necrozma(I know this doesn’t look like necrozma but I tried)she used to be the blinding one but something happened making her look black and she tries to steal sagolao’s and lunala’s light but she still has some of her sanity but she doesn’t show it story: she is combined to lunala and you are fighting her and manage to knock her off lunala but then you fall to the ground and you almost crash to the ground when she saves you from falling the rest is up to you
