8 Superheroes Who Had Their Identities Exposed
4. Batman
Batman's secret identity might just be the superhero community's worst kept secret. Not that his allies seem to be able to figure it out or anything, or because his villains are necessarily better at it either, but because Bruce's romantic partners keep figuring it out.
Although obviously not one of said romantic partners, Bane deduced the Dark Knight's identity simply by looking at his jawline, pausing for a second, and going "hey, that kind of looks like Batman's." Surprisingly few Batman villains have put two and two together, and if they do, most prefer to keep the secret to themselves, as they'd rather their rivals weren't privy to the same information.
Petty? Yes - but it also makes sense. Why would the Riddler want the world to know Batman is Bruce Wayne - or even Bane, for that matter? It matters more to them if they're the only ones to know, with both having exacted plots against the World's Greatest Detective after they discovered his secret.
But back to Batman's love interests. All just seem to figure him out at one point or another, with Silver St. Cloud the first to do so. Others to have deduced the Caped Crusader's identity include Tim Drake, Lex Luthor and the Joker, but the threat of revealing it to the public is what makes the knowledge so valuable.
