>>58083960Necrozma's forms are Necrozma forms, he absorbs the light of Solgaleo and Lunala's forms, they aren't there, they are just fuel, the pokemon in question is Necrozma. And no, the cores and cells not being pokemon isn't cope, it's a fact, it doesn't matter if we talk about lore or mechanics, those don't qualify as pokemon and can't be used as pokemon, so they can't be counted as forms, you can only possibly play with Zygarde's dog, snake and giant form.
You may as well think Rotom got too many forms over the years because he can get into machines that are also not usable as pokemon.
