Okay, .:KL:. is probably going to kill me for this, but I got a chance to look through the original TGS trailer (The first one, not the 2004 one) and I noticed something very peculiar in the summon scene (the one where the Unknown summons some of his friends). Anyway, when one of the Unknowns was summoned, I noticed electric sparks around that particular one. I checked with the others, and no electric sparks, leading me to believe that that particular unknown is of the thunder element, a.k.a. Larxene. While I know that this is a little far fetched, and that the sparks can be attributed to a lot of things, and that a new electric unknown could have surfaced, but I just thought that it should be known. Look on the trailer to see what I mean. Sorry if I'm wrong, but I just wanted to let you know.
