The X-Men are probably the most famous superhero team to work as an allegory for minority groups. Although the original intentions are sometimes embellished, it is easy to see by the 80s Chris Claremont had turned the X-Men into a diverse and relatable team.
Honestly, most groups could find something to love about the X-Men. They were outcasts trying to navigate a world that hated and feared them. Most teenagers feel like this at some point or another.
