Indeed, from ancien lovers to god-like individuals, there is a lot of theories on that matter.

For the Grimms, the show does not give us a lot to work on, so their existence have lots of theories beyond the fanbase : they came from the moon, they are enraged/cousins of faunuses, they were created in laboratories, they are soldiers of an advanced race... So many theories, and yet so little hints to work on...
