I forget WHO
was the one who commented, in a chat group, on what Barricade might have been doing during the final battle during the movie. They get credit for the initial idea of a "coffee break". X3 I just ran with it, this picture being the result.
Yes, I know
in the comic that Prime tossed Barricade through a highway pillar, but I'm going strictly by film-canon, here. The comics were drawn before the finalized cut of the film. Thus, Barricade and Scorponok are unaccounted for, in the final tally (it was never clear if Scorpy reunited with Blackout or not).
