Love these challenges. I am working in building up my portfolio, and having a theme to work on is excellent. My character is called Quesonator, the guardian of cheese, of Spanish descent.
My unexpected hero is called Hen-Man. He's like a Superman version in parallel universe, where people are half human half birds. He doesn't need wings since he can fly, but other Birdians with wings can fly naturally, not as fast or as good as he tho. Depends on how they are born. Some have wings, some don't, but technology is advanced enough so anyone can fly around. There are some who aren't born with wings. If a chick is in need, this guy come to help, due to very low crime rates on Birdia.
An evil team of thugs takes over the city, and a 10yo boy tech genius decides to do something about it. Along with his faithful K-9, he sets up his secret HQ in the warehouse of his dad's old plunger business and emerges as . . . "Dart Boy and Suction Pup" . . . fighting crime at night in an unexpected way. Also, what would it look like as a graphic novel?
