Captain Marvel**
Inferior Five
*Azzarello is supposedly writing an OMAC comic for Wildstorm (I think they recently obtained all of Kirby's 4th World stuff), but that doesn't stop me from wanting a crack at the franchise.
**BONE creator Jeff Smith just signed on to do a 4-issue Captain Marvel prestige series, which will kick major ass, but I still can't help but want another spin on the character (see my BIZARRO story "Captain Marvel and the Sham Shazam"). I may want to couple Captain Marvel with Plastic Man and kill two birds with one stone.
