User blog:TheVision185/Mavel: Avengers or not?

My friend says all of Marvel are Avengers. Obviously, those Utopian X-Men aren't avengers. And, I don't think 3/4 of the Fantastic 4 count as "Avengers" either. What do you think? Please let me know. And, is there such thing as an ultimate? Because, as far as i know, Spider-Man, Power-Man, White Tiger, Iron-Fist, and Nova are all Ultimates.
