Can some one help me out here. In ENERGON Omega Supremes head does that little pop off and transform thingy. Is Omegas essence in that little robot and he just wears the body like armor, or is that like a little head master dude with its own spark?
I believe it's just his own essence in a smaller body. Remember, this is Japan that wrote it, and Headmasters in Japan weren't "Nebulans", they were just the smaller component of a larger robot.
The 500th Episode (the one with all the wacky tag team battles and the really cool footage of the combiners linking up) established Omega's head as something like the Japanese Headmasters - he calls down his larger body, in train mode, much the same way that Optimus would summon his supermode components, or any other Super Robot would summon their extra parts to go to their superform for that matter.
i like this concept. i wished they had made cyb metroplex the same he had the protruding head an all.
