Quote1 Say it. "Damn all of them. There's only me." Say it. Say it! Because the city was built on divisions. Dead flower dolls. Gotham isn't a garden! It never was! It's a wild, bloody meadow! So stop wasting your lives! Don't take the pennies! Come to the land of giants! Go get what's yours get it! And let what's here die as it should, and grow something wonderful in it's place! Quote2
Mister Bloom src

Mr. Bloom was a Gotham City power broker and enemy of Batman.

Before gaining his powers, the man who would become Mr. Bloom was an anonymous participant of Daryl Gutierrez's underground metahuman experiments in Blossom Row. Said experiments resolved to grant ordinary civilians metahuman powers through the consumption of a device known as a "seed". Mr. Bloom was the only successful subject and after he was imbued with powers, he destroyed the lab and appropriated Daryl's research and his moniker as Mr. Bloom.


After disappearing for years, Mr. Bloom returned to Gotham City after the chaotic events of Joker's endgame. With his arrival came a new wave of former crooks turned metahuman powerhouses such as Precious Precious[1], Gee Gee Heung[2], and Qi Tsu. He provides his "seeds" to a select few, acting as implants that once rooted inside the body will grant their hosts extraordinary superpowers at the cost of their lives. Mr. Bloom then went on to try and sell his "seeds" to The Penguin. However, when Mr. Bloom revealed he had no intention giving Penguin his own "seed", Penguin had Mr. Bloom shot through the head. Through thanks to his meta abilities, Bloom survived being shot and impaled Penguin and his men, before leaving them all to bleed out.[3]

Mr. Bloom would go on to hijack a police zeppelin and crash it into a press conference meeting hosted by Geraldine Powers, in which James Gordon was meant to resign from the mantle of 'Batman'.[4] Despite indiscriminately killing several of the prominent business and government officials at the event, he claims that he is only there to celebrate with them. Mr. Bloom declared to Geraldine Powers that he wanted her to continue her Batman program, mockingly giving her a dollar bill as a "donation", before Batman and "Rookie" attacked him. Mr. Bloom would be temporarily subdued when Batman used the magnetic field of the Batplane to trap Bloom against the bottom of the plane, though he would escape by using his metapowers to create an electric discharge that deactivated the plane.[5]

"Don't let what happened to me happen to you friends. Be me today. Be this me. I'll give you the chance."

-- Mister Bloom

Batman located Mr. Bloom after his escape hiding out in a warehouse within The Narrows and after a brief confrontation -which resulted in the temporary destruction of "Rookie"- defeated the criminal thanks to a signal blocker designed by Julia Pennyworth and was arrested. Batman and the Gotham City Police Department transported Mr. Bloom within the Bat-Truck through The Narrows as a way to parade his capture. However, just before Batman was about to unmask Mr. Bloom, the Bat-Truck was attacked by metahumans dressed up like Mr. Bloom, allowing the criminal to escape once more.[6] Mr. Bloom grabbed Batman and took him with him as he escaped and began growing nearly two stories tall, allowing him to address the city and explain that he wants to grant the people of Gotham the chance to rise up and take their future in their own hands, revealing that he had planted his "seeds" all over Gotham. This causes numerous Gotham citizens to scrounge up these "seeds" and place them in their bloodstream, granting them metahuman powers, but symbiotically, granting Mr. Bloom more power himself.[7]

Task Force Z

"Does saving a life entitle you to that life, Geraldine? This seems to be the moral question going around these days."

-- Mister Bloom[8]

After his supposed death from being absorbed into a collapsing 'strange star'[9], Mr. Bloom was recovered by Powers International under the orders of CEO Geraldine Powers and was kept locked up in one of her laboratories for years.[10] Geraldine Power's would force Mr. Bloom to join a science division along with the Resurrection Man to create the Lazarus Resin pills that would eventually be used by Task Force Z. However, after learning that he would not receive his freedom or any money for completing this experiment, he caused the Powers International laboratory to explode and escaped.[11]Mr. Bloom would later be covertly recaptured by Project Halperin and forcefully indoctrinated into Task Force Z by Director Crispin.[12]

Mr. Bloom's first mission while press-ganged as a member of Task Force Z involved raiding a warehouse controlled by Mr. Freeze and his gang, who had been smuggling crates of Lazarus Resin.[13] During this mission, he temporarily abandoned his teammates -who were frozen in the warehouse- to pursue and kill Mr. Freeze, returning to save his field leader Red Hood from the zombified Arkham Knight by feeding her Lazarus Resin pills which satisfied her hunger.[14] He would later accompany Task Force Z in obtaining and reanimating the corpse of Floyd Lawton[15] and preventing the Kobra Cult from distributing the Lazarus Resin pills[16].
