He absorbs Nebby after it turns into the box legendary so he has an infinite source of light, and they separate after you beat the shit out of him. Nebby feels bad for Necrozma because it could tell he was in pain when they were fused, so when you find Necrozma in his normal form again on Victory Road and catch him Nebby is ok with fusing willingly with Necrozma instead of forcefully so that Necrozma doesn’t have to be in pain anymore.
Any future Pokémon that are actual antagonists will probably be done similarly to this, since they won’t wver make a Pokémon truly evil.
