What is the weakest team in fiction that could defeat Chris Claremont's X-Men?
Some clarifications
1. Chris Claremont's X-Men includes every character that was a member of the X-Men while Claremont was writing the title.
2. They get feats from every 616 Marvel story written by Claremont, including those he wrote after his iconic run. The board's consistency rules still apply, it's just that the only things that count re Claremont's works
3. It must be an actual team of characters that defeats them, not just a collection of characters from the same series
