My theory of a Mother Grimm is about as likely as the Grimm being the ancestors of humans. There's currently nothing supporting the possibility of such. However, the Mother Grimm originates from the fact that Monty had said in a podcast once that the main antagonist is a female. Which may refer to Cinder (but her arc supposedly ends next volume), the Queen (if Cinder isn't the Queen) and/or the Mother Grimm (If she is separate from the Queen)

Evil is subjective. And the Grimm are anything but that. Yes, the Grimm aren't evil. Because they're just doing what their base instinct tells them: Kill mankind. The proper term is that they're entities of chaos, whose purpose is to destroy humanity.

Grimm Dragons are awesome, yes. But everyone wants that already. I want something less generic.

Hell, you know what would be more awesome than that and the cheetah Grimm?

Motherfuckin' Grimm Phoenix. A bird burning with BLACK FIRE.

Eh. I'm one of those self-depreciating douchebags who always thinks his works is garbage unless it compares to masterpieces. :P

That's possible, as it's still up to air whether Cinder is allied with the Grimm or not. For all we know, she could be fighting AGAINST the Grimm.
