It’s been stated that in order to form a Kaita, the Matoran/Toa/Turaga components must be different elements. For example, two Po-Matoran can’t be in the same Matoran Kaita, but if one of the Po-Matoran were to become a Shadow Matoran, would they be able to fuse then with a Matoran of a third element? Do the rules apply to their current element or their original one?
Follow up: could three Shadow Matoran form a Matoran Kaita if they were all different elements before becoming Shadow Matoran?
