I know that I am out on a limb here, but maybe Shockwave is referring to his pet as Galvatron. I watched the movie twice and the second time I thought I heard Galvatron.

 

yeah its just Optimus, not sure why people try to pretend to come up with new things. guess we ran out of stuff to talk about.

 

I went to the part you're talking about, but all I heard was

"Ohh chahh wahhh! Optimus!"

 

He said "BUY MY TOY! OPTIMUS!".

 

I am at work so i cant be on long but trust me, this isnt made up. Shockwave really does say this. Its no chaos patterns, wishful thinking, or boredom. Its as clear as day on a HQ sample of it.

 

"Get out of this movie, OPTIMUS! I want more screen time!"

"what was that?"

"That......was Megatron's loyal servent, CHUGWAY!"

 

haha i went back and listened, it deffo sounds like what ts said but i think its just a coincidence and Cybertronian mumbling.

 

Shockwave also says "colossus" when he tells the driller to destroy the building.

 

This.

Come on people.

 

Shockwave also says "Victory Logical" during the Chicago battle.

 

It makes no sense to mention Galvatron when Megatron turned into Galvatron. Did Shockwave watch the animated film or something?

 

Thus my theory that he is schizophrenic.

And man I swear we're not making it up, I've listened to it a thousands of times, and you can [clearly] hear "WATCH" along his words [the first one sounds also an awful lot like "Megatron/Galvatron"].

 

Hes really says "Damn its, Optimus!"

 

Unlikely, you can hear a "TCH"-sound among his words.

 

(...face palm...)

In Chernobyl:
its the sound of the driller uncoiling around him...THEN he clearly only says "OPTIMUS."

 

Unlikely, you can hear the Driller sound at the background AND another sound who sounds an awful lot like Shockwave's voice saying "MEGALVATRON WATCH, OPTIMUSSS!"

 

If Galvatron/Megatron was supposed to be watching, all he would have seen is Shockwave chip off underground...

 

I heard "watch out now optimus" 

 

But He says something before "watch".

 

"watch out optimus" is what i'm pretty sure I heard but I still heard a screeching noise that sounded like tron...
