BB is a grimm creature I made a while back for a mission I was running. It's basically Arakune from Blazblue, classified as a grimm. It's amorphous form made it a bitch to fight physically though for the sake of ending that crapshoot of a mission eh stuff was fudged. Anyways one of the things BB would have been demonstrated being able to do is disguise itself as a humanoid. Kinda sorta, since it's a manufactured grimm. You know, someone decides to think "Hey maybe I can make my own Grimm" and BB is the product.
I chose arakune because I felt he matched the general aesthetics of grimm: black, red, white masks. Granted it's not animistic at all (Unless you include ameboid), but as we could see in V4, there exist grimm who don't really look like animals such as the Geist and Nuckaleeve, give or take.
When I first saw the pic I thought it was a cross between Ruby and Arakune, though upon further inspection who the humanoid part is suppose to be.
