Or that pokemon is gender blind, or doesn't fit into a chess analogy... O.o
Yes, but won't you think that there would be a Pokemon not known to Team Plasma that could be a part of the trio and yet there would be a way to stop Team Plasma? Who knows, there may in fact be 2 Team Plasmas rules by 2 Queens (bosses) (note the hidden picture in the video on filb.com) and that Reshiram and Zekrom are merely kings to both of them because of their coloring and also by how they seem to match?
