The box says "Omega Combat armor." Throw in the mech tech points on the weapon modes of the basic HA figures, and I'm starting to think Omega Supreme could be a big Autobot combiner in this film, with Prime being the central point of combination.
Take of that speculation what you will.
Props to who posted images in the first revealed Ultimate Prime combined pictures mode thread, of the Gundam that had the wings pointing down...Totally saw the video here and was like, "wow, what a difference that makes." Still not very interested in it, but hey, at least I'm not so deterred by it anymore, lol.
Also, no alt-mode for Leader Ironhide?
What gives?! lol.
