A simple question with the obvious answer being he is the world’s smartest man and yet he only wears a kevlar suit with a steel plate to protect his heart to protect himself from bullets, however, that’s not what I feel is his biggest weakness. no batmans biggest weakness is he likes Femme Fatales way too much. especially if they’re around 5 foot 7 to 8 inches tall with black hair. From batman number 1 story The Cat to Batman: Nightwalker (GN) Batman just can’t help falling for a bad girl…fortunately For Bruce the Femme Fatale he (generally) ends up with happens to be The Feline Fatale or a Wonder so he does not turn to evil.
(It can be argued that Wonder Woman as the Ultimate (good girl) Femme Fatale )
however aside for the obvious what do you think batmans biggest weakness is?
