How difficult would it be for Galvatron to TCB now that Optimus is gone? None of the remaining autobots can face him. He can whipe them out if he wants, and also any kind of human armed force that tryes to face him. And he can do this all alone. Probably he still has some of the bots made by humans, and can call some of the "dozen" remaing cons. Who is going to stop him? Or he will go to sleep for a couple of years to save the plot?
and why are we supposed to believe they stayed in our planet, would fight for any other tan optimus, or even care about humans?
Maybe they'll learn to like us over movie 5. That, and while they may not like humans, I doubt they'll like Galvatron anymore. So him coming around trying to boss them around would probably upset them.
I would think he would get those cons and build up a huge army for a power grab from the humans. If he could "infect" those man made robots whose to say he can't just make more transformium or may know where that location is they find it at in the movie since he was hooked into their computers. May make a whole new army it said one seed would make a city sized piece of the metal, that would be a big army. Galvatron may not even want to bother with the Dinobots I wouldn't if they were just off in the woods somewhere and didn't care what I was doing.
Well, if I threw a nuke at a building made out of Titanium, it'd still be destroyed. Doesn't mean titanium isn't strong.
