OMG DUDE I'VE BEEN WONDERING THE SAME THING FOR YEARS!!! LIKE WTH?!? WHERE TF ARE THEY??? i still have yet to find an answer

Where where they when...(Yes I know there might be a few avengers in these but they needed more)
Wanda kidnapped a town
Parker was dealing with Mystero
Nat was exploding things
SHE HULK WAS EXSITING
The Eternals where ethernaling...

Etc...

by Parker you mean Peter Parker? lol

Yea lol

iron man was blowing up his suits, thor was fighting dark elves, hawkeye was on a random shield mission, and the hulk was acting as Iron man's therapist (as seen in the post credit scene in iron man 3)

Yes (he was old)

Iron man was in Miami I think and hulk was not being hulk

VACATION, DANG IT!
