As a superhero, you could be forgiven for thinking that when you join an elite super-team like the Justice League, the last thing you need to worry about is disloyalty. After all, you’re banding together with a bunch of equally-heroic, like-minded individuals dedicated to fighting a common enemy. And yet a startling number of betrayals have taken place across the many incarnations of the League that have formed since its inception way back in 1960!
Of course, sometimes the reason for this treachery is that the Justice League member in question was suffering from the effects of mind control, brainwashing, or some other kind of mental hoodoo. But other times, their motivations are a lot more calculated – if not necessarily always badly intentioned – and are therefore a lot harder to forgive.
Indeed, one League member betraying the trust of the rest of team is always taken very seriously, and this otherwise compassionate fraternity of heroes has even resorted to expelling guilty parties from their ranks (at least temporarily). Regardless of the reason, nothing hurts worse for a crimefighter than when one of their costumed peers stabs them in the back – which is why I’ve pulled together this list of 15 Justice League members who betrayed the team!
