My guesses (top to bottom, left to right): Chromedome, Brainstorm, Mindwipe, Weirdwolf, Skullcruncher EDIT: going by Trent's link, I am probably right. The only one missing is Minerva, which is logical since they have to design her more carefully in order to create Nightbeat out of the same mold.
Theoretically headmasters do "combine"....as the head attaches to the body and is a separate robot of its own. I imagine that might be what it is referring to.
When are are they going to show off more of the Stunticons? I don't want to see ant more works in progress from these guys unless it is Menasor related.
Nothing is more unattractive then the FP hype machine. Will forget about this until they are released.
