I'll be the first to admit that I am not fan of the movie-verse, but I have to state that it's pretty stupid to bring Megatron back after he has turned into Galvatron. Correct me if I'm wrong and they are separate characters (like in IDW)

 

Wrong section.

 

Sorry, excuse me. I'm new at posting here. Going to fix it  

 

Don't worry, a passing moderator will probably move it to the right section.
It's kind of odd, but in the Unicron/AEC continuity, Megatron would be upgraded to Galvatron by the end of one series, then be back as Megatron at the start of another. I also seem to recall that in the Marvel UK continuity, we had Galvatron and Megatron at the same time. Regardless of precedent, I think it's kind of stupid. Why did Bay introduce Galvy in the first place only to revert him now? Granted, he didn't intend to come back for 5, but still. I still kind of wish they had done a full continuity reboot as well, but that ain't ever going to happen. Regardless of what he's called, I don't like Megatron's new face design. The tusks look stupid, and make him look kind of like a knockoff Ultron. I just hope they have a good reason for being back, but I'm not counting on it.
