They specifically cut that scene out for the sequel. Barricade rules: he'd make a good agent on Earth for either Starscream or Soundwave.
I think Ironhide would have damaged Megs or done more than Jazz did. Ironhide was all about his guns and I could see him trying not to engage Megs in melee, but rather just blast him from a distance. Jazz is second-in-command and Barricade seemed like just a low-level grunt. I definantly think Jazz could have taken him. Here's my "what if" - what if the Prime in the live-action movie had skills like the Prime in G1? Instead of rolling into Mission City and knocking over some garbage cans, what if movie Prime rolled over Blackout and then shot the hell out of Brawl/Devastator?
Word! But seriously though. What if Bonecrusher would have gone for Ironhide on the freeway? Think Ironhide would've emerged victorious like Prime?
