I know there's a slight chance this happens but after all he WAS the Omega Lock in the WFC universe and since there are some rumors regarding Stonehendge being the Omega Lock, is there a possible Omega Surpreme cameo, maybe he will fight the Combacticons? I dunno it will most likely not be the case but still what do you think? Personally I can't see that happening but who knows?
Don't really think we need him yet. And truthfully, I don't trust the writers enough to see them do him or any of the other "big guns" justice.
