Killer Time Lineart

Yeah, It's a concept for a fighting game I was thinking about featuring characters from history and fiction. From Left to Right:
El Zorro, Cleopatra, Joan of Arc, Don Quijote and John Henry. There were other characters, but they didn't fit the page(namely, Mulan and Hercules). I haven't settled on what the final boss oughta be, but there's still time. I'm flirting with the idea that it be Caligula...
