I don't have them handy. But one Zod had no armor...he looked kinda like M. Bison. The second Zod is the one in that HUGE red armor, but under the armor, he was a Superman clone. The third Zod was also in pretty big armor, except it was black and had spikes coming out of it. He also wore a helmet, but under it, it was some tough old dude with male pattern baldness. Looked a bit like Ra's Al Ghul, lol. Which one(s) are you familiar with?
Yup, that's Zod #2, who is really a Superman clone underneath. I don't remember the history...in typical Kelley fashion, it's kind of murky and convoluted. All I know is that he used to be some guy, he hated Superman, I think he somehow got trapped in the Phantom Zone, where he learned all about Superman and Zod, then ended up with Superman's face and body and took on the identity of Zod.
Or something.
