I think the funniest thing about this is that Superhero Girl actually succeeded. She got a wanted criminal off the street, and now he's reformed and a contributing member of society. Well, one hopes. Considering all the horrible things certain businesses and business people do, maybe King Ninja's just found a new outlet for his crime. But I choose to think he's reformed through discovering his love of working in an office. It happens.
Btw, thanks so much for all the helpful opinions on self-publishing Superhero Girl, and also on the copyright issues. I have a few ideas for a title, and a few options for printers, so thanks very much for pointing me in the right direction. You guys are the best!
