Eduardo Flamingo is an emotionless, unfeeling killer that has a tendency to eat his victim's faces after he has murdered them. According to Gabriel Santo, Flamingo has an impeccable kill record. Jason Todd has rallied a defense against Flamingo, but wound up with a bullet wound to the face and knee-cap. Flamingo then turns his attentions to Red Hood's partner Scarlet. Flamingo then tugs at the seams of Scarlet's mask before she gashes him with one of her blades. Feeling responsible for the girl and her condition, Robin jumps into the fray to help, but receives four bullets to his cape-protected spine for his troubles, paralyzing him from the waist down. Dick Grayson delivers a much-deserved boot to Flamingo's face. It is ultimately Jason Todd who finishes things up. When Dick is nearly tossed over the side of the building, Jason uses a construction digger to scoop Flamingo up along with other assorted rocks and debris and deposit him over the edge plummeting to the Earth below. Commissioner James Gordon later tells Batman that Flamingo's body was never found.
In September 2011, The New 52 rebooted DC's continuity. In this new timeline, Flamingo is first seen among the villainous inmates at Arkham Asylum. He joins the inmates seen attacking the Batman before Joker appears to come to Batman's aid and the pair work together to beat back the group of rampaging inmates. During the "Forever Evil" storyline, Flamingo appears as a member of the Crime Syndicate of America's incarnation of the Secret Society of Super Villains. During the "Gothtopia" storyline, Flamingo was later seen among those who have taken over Arkham Asylum. He and Nocturna later get knocked out by Batman. While Batman is teased by Julia about his romantic failure with Catwoman, he gets distracted when Flamingo's motorcycle skids past him. Batman makes a hurried u-turn and catches up to his prey, running him down, and sending the assassin flying from his bike. Batman has taken down Flamingo and allows the man to wake in a cemetery. Batman watches Flamingo get up and leave, in order that he can follow him back to his employer. En route, Flamingo receives an invitation to Catwoman's impending murder. Batman follows Flamingo to the Moffat Building, where he discovers the aftermath of the shooting. Dragos Ibanescu lies dead and both Catwoman and Killer Croc are traumatized by Jade McKillen's death.
