Granted, nobody wants to be labeled a mutant, but I think we all want to have superpowers. If I could choose among the X-Men, there are two that really appeal to me: Angel and Pyro.
Angel has big wings that allow him to fly. That's an invaluable asset for any superhero and it seems to be something very liberating.
Pyro can manipulate fire, which doesn't seem like a big deal nowadays, but check the movie Castway to see how difficult it is to make fire without any help. Plus, fire just seems much cooler than ice. Likewise, Pyro is just so much cooler than Iceman, aka Bobby.
Both Angel and Pyro remind me of Greek myths (Icarus and Prometheus) but I'm probably reading too much into this.
All I know is that I definitely don't want to be Storm - talk about a party pooper.
And which X-Men would you like to be? (It's Ok to say Storm - I wouldn't mind having Halle Berry's real-life superpowers.)
