Been thinking about the same concept- possible reason why the big fellas toy wont have robot forms? (other than the cost of the development and tooling).
After some examination I reccon i saw one of the feet transforming and waiting in position to merge - didnt seem reluctant to hook up? I could be wrong though.There was one 'master' robot and the rest were made slaves once gestalt transformation began. I would have to watch it again but I seem to remember Scavenger chaining in the other constructicons to merge them together across the entire body rather than having one robot for each limb etc as in G1. The other constructicons didn't seem to happy about it. Would explain why the separate units couldn't get up after being hit by the rail-gun too.
Ill tell you one thing for sure- once i get the movie on dvd im going to be doing a lot of slow motion detective work. Every time i watch the movie i seem to find something new!![]()
