>Hurr durr Superman can't have a health bar because he shoudn't get hurt by gangsters and bank robbers

Then don't have him fight standard human mooks like Batman and Spider-Man do? Supes regularly faces wacky aliens, monsters, robots and 5th dimensional imps. The main crime syndicate of Metropolis, Intergang, even use advanced weapons and technology taken straight from Apokolips. I know normalfags and casuals aren't aware of this but for fuck's sake it's not that hard to come up with decent enemies for him to fight in a game that you can believably lose to.
