I see. This theory is similar to the 'One Hivemind' idea since long, long ago.

I won't say that it's wrong, just that I've already stated reasons why I don't think the Faunus are that directly related with the Grimm. Even if it was, I don't think the humans know it yet.

Also, I forgot to mention something in my theory; just putting it here as reference since it doesn't affect both of our theories. While we know that the Grimm's body would dissolve into black smoke, it can be that only the black body and flesh that does that.

Maybe the exoskeleton doesn't dissolve. This reinforces the idea that the masks somehow controls and keeps the Grimm alive.

Also - this is a small chance, but - it could be possible weapons are forged from Grimm exoskeleton. We already know that it's so ridiculously tough that almost nothing could penetrate it. It may make excellent material for forging weapons.
