Okay, this may sound like a dumb question, but I'm really curious to know. Who is the most powerful member from X-Men, and the most powerful member from the Avengers? From X-Men side, I'll say Phoenix and from the Avengers side, I'll say Thor. Any suggestions?

Wait you mean every person that was a avenger ever at one point or another?
