Why on Earth would the FF join the Avengers?
It would depend upon how they are introduced, being after instead of before The Avengers like the comics. So far in the MCU, if enhanced you are part of "The Avengers", if deemed worthy and then you have those seen as second class, for lack of a better term, unaligned or criminal grouped enhanced beings like Scott Lang. So perhaps Johnny upon getting his power looks up and thinks we, or I can be an Avenger while Reed would be holding out that we are much better than them and don't need to join.Why on Earth would the FF join the Avengers?
