A LEGO "Character and Creature Building System" or (CCBS) skeleton with an upper limb piece and a red armor piece.
The same setup as the last picture, but I am holding a Kanohi Mask Ruru from Bionicle onto the hole to replicate how it would look if it were attached.
The same thing as before, but from a different angle.
I admit that I'm a #CCBS defender, but I DO wish that the CCBS Armors allowed for Stud and Axle connections so we could put #Bionicle #Kanohi on them. Would be fun to turn masks into Pauldrons or something.
