10 Insane Times Heroes Became Horror Villains

10. Batman - The Batman Who Laughs

What if Batman was the Joker? What if Batman was Judge Death might be more accurate, in this case.

Infected by the Joker at the point of the Clown Prince of Crime's death, this alternate-universe Batman became a hybrid of both, combining the Bat's tactical nouse with the Joker's bloodlust sadism.

Traversing from universe to universe, this Batman who Laughs would stop at nothing until every other version of himself was either infected or killed.

Never underestimate 'our' continuity's Batman though, who valiantly powered on through his own poisoning to defeat the Batman who Laughs, cure himself and save both Gotham and the Commissioner from his vile machinations. As anyone who has ever sat through a Friday the 13th sequel knows, however, the end is never really the end, and the Batman who Laughs 'lives' on, to further poison the DC Universe with his insanity.

Judge Death himself would be proud.
