bu now almost every hero ever created was an avenger
who was never an avenger but should be one?

me, i would like to see IKARIS from the eternals in the team, he is a VERY powerful charecters with cool costume and can
add the (sort of) god factor to the team.

Silver surfer and fire lord - for the cosmic element

ghost rider - for a supernatural element

the Invisible woman - very powerful and strong woman , it the thing can be on 2 teams so can she
(i know, she was an avengers for 3 issues but she can be back)

who else?
