Black Noir is the name of three characters from the comic book series The Boys, created by Garth Ennis and Darick Robertson, and the television series and franchise of the same name, developed by Eric Kripke. In both the comic and television series, Noir is a member of the hedonistic and reckless Vought-American superhero group the Seven and is depicted as a "silent ninja" type parody of Batman, Snake Eyes and Deathstroke.

In the comic series arc Over the Hill with the Swords of a Thousand Men, Noir is revealed to be a clone of the Homelander and enhanced with Stormfront's DNA, created to replace him if he ever went rogue. Driven insane by a lack of purpose, Noir resolved to frame the Homelander for various atrocities as part of a plan to gradually drive him insane and replace him. However, after the Homelander and Billy Butcher team up to face him, he is ultimately killed by the latter. In the television series adaption, Noir, portrayed by Nathan Mitchell and Fritzy-Klevans Destine, is instead depicted as a brain-damaged African-American Supe named Earving, who is loyal to Vought CEO Stan Edgar. In The Boys Presents: Diabolical, Noir is depicted guiding the Homelander in his early career. Following Earving's death in the third season finale of the main series, starting with the fourth season Mitchell is portraying a replacement Noir in the series called Black Noir II.

In the comic series, Black Noir is depicted as a member of the Vought-American-sponsored superhero team, The Seven, and the only superhuman created by Vought-American who can beat the Homelander in arm-wrestling. Until the events of the series' climax, it is implied that the Homelander had raped Billy Butcher's wife, Becky, who then died giving birth to a superhuman baby Butcher had then killed, a crime actually perpetrated by Black Noir, who has been impersonating the Homelander during his free time for years. In Issue No. 40, the Boys receive a series of incriminating photos seemingly showing the Homelander engaging in grisly acts of murder, cannibalism, and necrophilia against men, women, and children. The series eventually reveals that the Homelander cannot remember either these incidents or the rape of Butcher's wife, and suggests that the Homelander has dissociative identity disorder and may have sent the photographs to Butcher himself. In private, Homelander shows signs of suffering a mental breakdown, talking to his own reflection in a mirror, and having bouts of nausea over the images, genuinely confused and horrified by their contents, events which a secretly watching Frenchie decides to keep from Butcher. Concluding he is "damned" for the acts depicted in the photos, the Homelander decides to give in to any intrusive thoughts that cross his mind.

Following Herogasm, in which Black Noir randomly "thumbs up" Wee Hughie's posterior while the latter was infiltrating an orgy (revealed in Highland Laddie to have whispered "good soldier" to the deeply traumatised Hughie while doing so), the Homelander resolves to free himself and the superhero community from Vought-American's control. In Over the Hill with the Swords of a Thousand Men, he leads the other superheroes in a coup d'etat against the United States, launching an attack on the White House and killing everyone inside, including the Vought-controlled Vice President, under the guise of doing so for the Guy From Vought. During the subsequent confrontation between the Homelander and Butcher, surmising why Butcher must hate him, Black Noir arrives in the Oval Office and reveals himself to be a clone of the Homelander created solely to kill and replace him if he ever went rogue. In addition, he was also enhanced with Stormfront's DNA making him a binary clone. Gradually being driven insane due to not being allowed to kill the Homelander, Noir reveals that he had committed the atrocities documented in the photos amongst other actions (having destroyed the plane during Herogasm) and raped Becky to set Butcher and the Homelander against one another so that he would be given authorization to fulfill his purpose. Outraged, the Homelander attacks Noir, who proceeds to tear the Homelander apart. Before dying, Homelander manages to seriously injure his former teammate, allowing Butcher to later finish him off with a crowbar, before embarking on his own genocidal plan to kill all superheroes and those "Supes" with the genetic potential to become them.

In the live-action television adaptation, there are two characters who operated as Black Noir:

The first Black Noir is portrayed by Nathan Mitchell while Fritzey-Klevans Destine portrays Noir in flashbacks. Largely silent, he primarily communicates in a series of silent gestures and intimidating body language, and possesses a healing factor coupled with a penchant for artistic exploits, standing toe-to-toe with the Female and effortlessly playing classical music on a piano in the first season. In the second season, Noir is revealed to be the loyal enforcer of Vought CEO Stanford "Stan" Edgar, who directs his every action in combat, including killing the super-terrorist Naqib and tracking down Billy Butcher and the Boys. However, Noir also displays simple, friendly character traits of his own outside of combat, such as giving Naqib's son a teddy bear, befriending a Vought programmer while looking for Butcher, and breaking down in tears upon learning his powers originated from Compound V injections given to him by Vought with his parents' consent as a child. Later, while attempting to apprehend the then-rogue Starlight, Noir is put into a coma by Queen Maeve after she exploits his tree nut allergy by forcing him to consume an Almond Joy and kicking his Epi-pen out of reach.

In flashbacks to the Cold War depicted in the third season, Noir is revealed to be a man named Earving who had begun his superhero career and joined Payback, Vought's predecessor to the Seven. However, Noir and the rest of his teammates were subject to career sabotage and physical abuse by team leader Soldier Boy. In 1984 amidst a joint operation with the CIA to stop a communist government in Nicaragua, Edgar secretly assigned Payback to trade Soldier Boy to the Russian government so Vought can eventually replace him with Homelander, who had been conceived with sperm obtained from Soldier Boy. Throughout, Noir complained about having to wear a helmet that covers his face as he wanted to be the "Eddie Murphy" of superheroes, though Edgar told him Vought believed a publicly black superhero was neither profitable nor acceptable at the time. Amidst an attack on their camp by Nicaraguan and Russian soldiers, Noir led Payback in cornering and attacking Soldier Boy. They eventually succeeded in subduing him, though not before Soldier Boy left Noir permanently disfigured, mute, and brain damaged. In the present, upon coming out of his coma and learning of Soldier Boy's return to America, Noir cuts his tracking chip out of his arm and hides out in an abandoned Buster Beaver's Pizza Restaurant, where its mascots and his imaginary friends reenact the abuse he suffered from Soldier Boy to convince Noir to face him instead of running. Upon returning to Vought, Homelander kills Noir for withholding his knowledge of Soldier Boy being Homelander's biological father. Before he dies, Noir sees Buster Beaver and his friends as they mourn his death and state that they are proud of him.

In the 2021–2022 promotional web series Seven on 7 with Cameron Coleman, which bridges the events of the second and third seasons of the live-action adaptation, Noir is revealed to have awoken from his coma and been charged by Vought with tracking down numerous Supes that had escaped from a psychiatric hospital as well as filming promos for Vought's streaming service, Vought+, on which his film Black Noir: Insurrection is to be released.
