Another oft-exploited aspect of this is Batmans technology. Sure, he may not have Supermans vast arsenal of superpowers, but he does possess the resources and the technology to level the playing field. The Dark Knight Returns, often held up as Exhibit A of why Batman would beat Superman, showed Batman using a powered exo-skeleton that enhanced his strength to Supermans levels. So even in a direct fight, Batman could find a way to take Superman on in his own game, right? Right? Not necessarily. For starters, technology has its limits. It needs a power source, and it would have to be a power source that can last as long as Supermans own power source. Whats Supermans source of power again? Oh yeahthe sun. As long as that thing is up there, Superman will be able to keep on going. Even if Batman could somehow black out the sun, hed still have the vast reserves of solar energy Superman has soaked up over the years. Eventually, Superman would find a weakness in technology. No matter how advanced technology is, its still made up of smaller components that can fail and with Supermans x-ray vision, telescopic vision, super hearing, superhuman thinking, and heat vision, he could find and exploit a weakness in any sort of Bat-armor. Even if that weakness is just pummeling it at superhuman speed until its pushed to its breaking point.
