Batman's consistent heroism without a single power helped make him a staple of comic book culture. He also paved the way for other superheroes without powers in the industry. However, there are a few powerless heroes who would beat Batman in a fight, even if the Caped Crusader had prep time.
Updated on September 9, 2022 by Scoot Allan: There are several ongoing and sometimes heated fan debates that discuss various characters who can defeat Batman. The Great Darkness and his powerful Dark Army took Batman down a peg during the Dark Crisis on Infinite Earths. Batman is usually at his best facing stronger villains with incredible powers. However, there are some comic book characters without powers who could still give the Dark Knight a run for his money.
Tony Stark has often been equated as Marvel's version of Bruce Wayne, albeit with a little extra charm. However, Stark may have more in common with DC's Lex Luthor, given their choice for evening wear. Stark's biggest advantage when going up against someone like Batman are the powerful Iron Man armors in his closet.
While Batman has his own armored suit and a few heavier-duty models, Iron Man has a suit built for every occasion and any potential enemy he encounters. Both heroes excel with some prep time, but Batman won't have enough firepower in his utility belt to deal with Iron Man's latest war machine.
