This is gona be confusing for people that aren't into the cartoons, we had "devestator" (brawl) in the first one geting fucked up now in the sequel we have something by the same name but looking totally different.
Thats assuming of course they actually keep the name devestator.
I dont get how that wheel thing was only one of the constructicons, if thats just one (and it looked to be 1.5-2.5x the size of prime) id hate to see how large the fully assembled devestator is.
The decepticons badly need mroe screen time to develop their characters more, i think that would be more interesting than listening to labeouf say "nonononononononononnnonononononno" like he does in every fucking movie he's ever been in.
