Though he's not the most intelligent of Superman's foes, what Bizarro lacks in brains he makes up for in brawn—as both villain and antihero.
Few villains in the DC Universe are Superman's equal in power, but there is one who can always go toe to toe with the Man of Steel in a fight—his twisted doppelganger, Bizarro. The tragic result of a bizarre science experiment gone horribly wrong, Bizarro is an imperfect duplicate of Kal-El, with none of his intelligence or self-control. Looking like a pasty white, zombie-like version of the Last Son of Krypton, he invariably strikes fear into those he encounters. Often a creature more to be pitied than feared, Bizarro nevertheless is as dangerous as it gets...whether he means to be lethal or not.
There have been many versions of Bizarro over the years, some created by science and some by magical means, but he has been a persistent thorn in the side of Superman since the earliest days of the Silver Age. Usually wanting nothing more than to be seen as the hero that his famous counterpart Superman is, he has often developed a strong hatred for his "perfect" brother. Sometimes misguided, sometimes genuinely malevolent, and even sometimes a true hero himself, Bizarro is nevertheless a force to be reckoned with.
