So let me see:
Supermen:
Pre-Crisis Superman
Post-Crisis Superman
Red Sun Superman
Superman 1 Million
Superman Prime
Superman (Kon-El)
Electric Superman
Batmen:
Batman
Batman Beyond
Batman 1 Million
Kingdom Come Batman
Hmm, I wonder who'd win this fight? 🙄 Even with prep, the Batmen go down hard. If I missed a Superman or a Batman, I apologize, but it wouldn't make a difference to the outcome even if I did.
