Are you extra certain about the Mata hands? The whole thing might be part of a larger, single mold. G1 had quite a few of those way back when.
With a couple of bizarre exceptions, an overwhelming majority of these fall squarely in the realm of "identified" for me. That Vakama Hordika shot never ceases to elude me, though. If I had to guess, it's from an old foreign-language ad that got taped or photographed as a still from someone's crappy TV.
@Vezok Haha, we all know who it depicts, man. Who do you think we are?
I mean, if it was on the Bionicle Wiki, there's no way to tell. You gotta think for yourself, and not let a wiki blindly tell you what is canon and what's not.
