I couldnt help but notice that alot of people seem to be saying they'd like to see Megatronus before Unicron, though when you think about it, they can't really do that. I mean, sure, it makes sense to introduce the lesser evils first, though if this series is really going to get into the Mythos of Unicron and Primus along with the 13 Original Transformers (i mean, if any series ever will, its this one) then we need to have things introduced to us in a certain order. If they start with the 13, then we learn of Primus and Unicron through the backstory of the 13. Then, when the bigger guys are introduced, there's nothing to tell, no story, only what happens, no mythos. But by bringing in Unicron (and Primus?), then we get to hear about them, then deal with them. then, at a later point, we are introduced to the Fallen, or the 13, then get to hear their tale and deal with them. Now obviously most of that is speculation, but it makes sense, doesnt it? I can see it playing out like that in the future. I think that may be why Unicron is in the spotlight first.
