When a boy Beowolf loves a girl Beowolf enough...

Okay, seriously. At the moment, it's not exactly clear yet where they originate. From the bits of info that we have. Four possibilities pop up.

A.There's a Mother Grimm (referred to as the Grimm Reaper by a few) that gives birth to the creatures of Grimm out there.

B.Grimm emerges from an animal who lost its soul. This also brings the possibility of humanoid Grimms into existence, as this theory hinges on the idea that the Grimm comes from the lack of Aura.

C.They're pretty much the equivalent of dinosaurs that didn't go extinct and act as the natural predators of humanity.

D.They are humanity's experimentation with aura going FUBAR.
