Yeah, he was just hollering because the Matrix was passed to Ultra Mangus and NOT destroyed, which he would have obviously preferred.

 

Of course the irony of all this is that, had he simply steered clear of Cybertron and it's moons, he probably could've consumed half the universe before the Matrix would have ever been an issue.

Maybe he hoped to catch them offguard before anyone figured out how to use the Matrix.

 

In the Marvel comic run Unicron powered down and drifted towards Cybertron to try avoid Primus detecting him and preparing Cybertron for battle. Which when you think about it is pretty weird considering if a big planet was drifting towards you I think somebody would notice.

The answer is "funky light show"; he only inflicted actual damage via his hands of doom and stuff.

 

Hmmm.. I have to disagree, he inflicted damage to several spaceships with his whirlwind breath or whatever that was.

I just want to know what had happened between Unicron and the Matrix before to where Uni knew it could hurt him?
