And then they all explode. Multiple times. Because Transformers movies.

 

You forgot to mention that some robots may urinate or fart during the movie, because audiences love that. See? Just like a Hollywood brainstorm session

How were they duped?

 

That sounds like garbage tbh

 

Megatron used a human politician to exile them. Optimus agreed to the exile thinking they were being kicked off Earth. They all boarded the shuttle and... Surprise! It was a trap. They were set on a collision course with the Sun. They were tricked into thinking the shuttle was being used to send them off Earth peacefully into exile. Hence they were duped.

In all fairness, the humans were too. By this guy and his smear campaign against the autobots.



Unlike this guy...

Who only pretended to leave to teach the humans a lesson about needing him. While thousands were killed. awesome.  

Edit: the end of my post was cut off. So I fixed it.

 

No, really?  

 

Thinking about it, Sentinel already told Optimus he was going to enslave humanity and make them rebuild Cybertron with Earth's remaining resources. Sentinel's kind of an idiot for killing his slaves. Wonder if Optimus even thought that Sentinel would do that?
