Re: Should Whiplash be brought back for IM3?
While I'd say no for the most part, I wouldn't mind it (if they DID), if they used him to show Tony getting overconfident again, just before the Mandarin shows up.
In other words, Vanko attacks, Tony whips his butt easily and explodes with "remember how he put up a fight before, now I can take him down with a one repulsor tied behind my back" arrogance.
Would nicely set up the shock of his life getting thrashed by the Mandarin or one of his employees (Ghost?).
I like the 'rogue's gallery' reason too, even if he's seen just sitting in a cell next to Blonksy - awesome!
