Yup that's right.
As I work on the Silver Age for the Zenith Universe, I have my Superman (Guardsman) and I have my Wonder Woman (Lady America) but I am missing a Batman. The guy who uses brains and skill instead of powers. The guy who everyone wonders if he is a hero or a villain. The guy, who when the American Government says "Unmask or go to jail." in the 50's doesn't say anything, he just ignores them and keeps going.
Now the hard part of this is that I don't want him to be a dead-to-rights rip-off of the Bat. Certainly Guardsman doesn't strike anyone as Superman on first blush. He isn't an alien, he started in 1944 and was powered by a magical helmet. Lady America (nicknamed the American Amazon for those who might miss it ;) ) isn't directly Wonder Woman either. She has no powers, uses Martial Arts and is a wrapped in the flag patriot. Essentially she is Wonder Woman masquerading as Captain America.
So how to have a Batman who isn't really a Batman at first glance.
I am wracking my brain on this one and coming up empty, so I turn to you all for input, ideas and guidance.
One caveat, please don't offer me characters from your own campaigns or creations unless you are also giving me permission to use them in publishing ventures (for which proper credit will be given to you if the character is used) as well as to twist, fold, spindle and/or mutilate as I see fit to make them work in the Zenith Universe.
Just had to get that out of the way.
