It's an age old question, but one that always provokes some interesting thoughts - and I'm also finding my answer changes over the years. If you could pick one superpower - invisibility, superstrength, flight, etc - which would it be? Is there a superpower that is vastly underused in the whole comic-book genre? As an extension of the question, is there a superhero you wouldn't mind being or do you think that the great power and great responsibility would be a bit much?
