Question: what do you get when you cross a heartless murdering machine with Freddie Mercury? Answer: the Flamingo. As another creation of Grant Morrison during his time on Batman, Eduardo Flamingo is undoubtedly the most flamboyant Bat-villain ever created. Lobotomized by the mob in order to create the perfect hitman, the Flamingo is a sociopathic, psychotic, ruthless killing machine who literally feasts the faces of his victims. After being brainwashed by the mob, he proceeded to kill each member of his family before becoming a contract killer. Oh! And he also happens to have an affinity for the colour pink. Sporting an outlandish pink uniform while riding a hot-pink motorcycle, the Flamingo likes to kill his foes in style while humming and another one bites the dust! (okay maybe that last bit was made up, but you get the point). Although the Flamingo has made only a few appearances since his introduction in Batman #666 (2007), each occasion has been quite unforgettable. The contrast between his appearance and his actions has made the Flamingo one of the most memorable villains created in the last decade.
