Silly idea I had while I was watching the movie: we know that the Harvester is a giant machine built to destroy suns for energy. Now my thought on this was: could it be an impression of Unicron? a line-up of semi-similarities I saw: big machine(harvester) - unicron can be seen as a big machine eats sun for energy(harvester) - eats planets for energy(unicron) is feared by everyone except a few decepticons(harvester) - is feared by everyone while sometimes the decepticons use him(unicron) The only thing that I can think off that can dispower my statement is that the Harvester isn't a transformer and that I have read an interview with Roberto Orcci on rottentomatoes. He explained that there was an idea for tf3 with unicron but he wasn't that keen on it because of the size of Unicron and that there would be a lack of emotions for him(I can't explain it that well, check rottentomatoes for the full interview.) So what do you guys think about this?
