You may have noticed the little “dots” in the center of the BOHROK KAL headplates, seen for example in the ToyFare article . Those little dots are actually identifying symbols of the BOHROK KAL. The above image is some detail from a TAHNOK KAL headplate, as seen on the inside-back cover of the BIONICLE ™ Issue 9 comic.

Click the above image to get a look at all six BOHROK KAL symbols. These were scanned from the inside-front cover of the BIONICLE ™ Issue 9 comic and then enhanced for detail. And yes, the symbols look almost exactly like the BOHROK KAL “hands”.
