Whether you are die-hard comic book fan or a guy on the street who knows next to nothing about comics, you know who the joker is; talk about any top list from the greatest villain of all time to dc comics top villain, joker has hardly ever missed the top spot. though the joker has fought many superheroes from dc universe, namely the superman and the wonder woman; his last stand was always facing the dark vigilante who looks over the gotham city; the batman. the joker is a yin to the batman’s yang; he just cannot fathom the idea of batman’s morality and has become obsessed to make batman see the error of his ways.the character of the joker was created by bill finger, bob kane, and jerry robinson for the debut issue of the batman comics on april of 1940. the character of the joker was initially planned to be killed by the end of the first arc, but his popularity among the fans become the key to his survival and now, even after 75 years, he is still known as one of the greatest villainous character ever written. joker is certifiably insane, mass murdering lunatic, he is truly a rebel without a cause. like his counterpart, the batman, the joker has no super power or special ability but unlike the batman he has no cause to do what he does. the clown prince of crime creates mayhem for the sake of chaos, and this makes him actually the most dangerous villain. without further due let’s get on to the reasons why the joker is the ultimate villain of all time.we have seen that most powerful of the villains have the reason behind the carnage they cause but not the joker. he is the agent of chaos, and he needs no other reason, joker sees the world as one cruel joke, with corrupt authority figures as its head. he holds no one and nothing dear and that leaves him with no weakness, he simply has no reason, not cross every line there is; he does whatever amuses him. he is an epidemic of violence; he wants to destroy the order of the world and bring the anarchy.
