I always bought into the notion that the best way to break into comics was to write a character whose title doesn't sell much, giving you the freedom to do almost anything you want, since nobody will much care. So, Alan Moore got to do cool stuff with Swamp Thing, and Frank Miller got to play with Daredevil. I always imagined myself writing an obscure character like Man-Bat or Dr. Midnight or OMAC or Red Tornado. But I would love to do Green Arrow or Superman. Or, hell, X-Men, why not?
