That's what the comic books did.elvor0 said:To be fair/I always find it strange that there's such a big argument about that when TDKR is the most famous example, respectively to the two people I've quoted. The only reason that worked in The Dark Knight Returns was because Superman had just eaten a nuke and the US was suffering the effects of a nuclear winter, thus preventing Supes from regaining his strength and the fact that he spent most of the fight trying to get Bruce to stand down. I love me some Bats, I'm a huge fanboy, but that's why it worked. Heck, Bats didn't even really do that much planning for that fight. Shows up in a mecha suit, that presumebly he'd been working on for a while because he was getting gold, and just tells Green Arrow to shoot Superman at the appropriate time, that was the whole plan.
The movie universe is a completely different thing, possibly with completely different rules.
Man of Steel has never established that this is a realistic universe.
Sure, it looks like our Earth but regular humans may be able to reach action hero video game character levels of power (from what I've read, in terms of what he will be capable of, this Batman will blow all the previous ones out of the water), which combined with a power armor will probably be enough to match Superman's power levels.
