Re: Which members of the Guardians of the Galaxy should join the Avengers?
None of the ones announced for the GOTG movie need to be Avengers, ever.
Of the comic-book GOTG that apparently don't get the call for the big screen: Mantis, Moondragon, and Vance Astro are the only ones who have done stints with the Avengers. Other than those three, there's no crossover with the Avengers at all.
