The most recent trailer for Infinity War has already shown us that Peter Quill won’t take any of Tony Stark’s crap when they get to work formulating a plan to take Thanos down, so now it’s a matter of waiting to see if they can get over their rivalry when the battle kicks into high-gear.
Having said that, they have never met each other before, which means Avengers: Infinity War will be the first time that either of these heroes has met someone with a similarly dry and sarcastic sense of humor.
When it comes to smartasses, no one can compete with Iron Man or Star-Lord.
