What's the official name for this Nihilego form(e)? I see some people call it the "mother beast" while Bulbapedia just refers to it as a "merged" form.

Do you think it will ever become obtainable (sans Lusamine obviously)?

What would its stats look like? Typing change?

Seriously I need some answers, or at least some cool headcanons from other anons, because my autism is flaring up again.
