At the 2010 Motor City Comic Con, I met a guy who was a superhero and did wear purple, although probably just for the duration of the convention. I don't know who he was, but he was the Phantom to all who asked.
The Phantom is an interesting superhero in that he has no super powers. That's doesn't sound much like a superhero to me. Ahh but he is a superhero and he has been fighting bad guys for about 80 years.
On second thought, if he doesn't have any super powers but is a superhero, perhaps I could be a superhero, too. Then I would dress in purple and achieve my dream.
