This is my theory on the mask

Originally, there was a sixth [species] of Grimm, one in the shape of a human. As all Grimm featured as of yet have four eyes and bone-like structures, it may be safe to speculate that they had them too. What if (and i dont want to start a war on this) the "black parts" of Grimm dissolve leaving the bone structure. If all of this is true, then the mask that he wears may originally have been, or is, the facial structure of the "sixth Grimm", worn be Adam to strike fear into his oponents.

And, this may be the wrong thread and a longshot, but what if the "sixth Grimm" was hunted to [extinction] by man, and "Crimson" is part of a psuedo-cult trying to [ressurect] them
