Brock Rumlow (Frank Grillo) looked like an awesome SHIELD Agent during Captain America: The Winter Soldier, but comic book fans’ spider sense was going crazy as they knew Rumlow was better known by the name CROSSBONES. They were proved right when Rumlow turned heel and revealed himself to be a HYDRA Agent. Soon though The Falcon (Anthony Mackie) battled him and Rumlow was taken out by a collapsing building and taken into SHIELD custody…until now!
The leaked set picture shows Rumlow (Grillo) in full Crossbones attire:
Crossbones was created by writer Mark Gruenwald and artist Kieron Dwyer in Captain America #359 (October 1989). Crossbones usually appears as a henchman of the Red Skull. He carried out the assassination of Captain America, although Sharon Carter, who was under hypnosis at the time, is believed to have fired the fatal shots.
In the comics a young Brock Rumlow led the Savage Crims gang on New York’s lower east side. After he assaulted fifteen-year-old Rachel Leighton, two of her brothers assaulted Brock, and the elder brother was killed. Rumlow fled, entering Taskmaster’s school for criminals. Within three years, he became an instructor there under the name Bingo Brock.
As a mercenary, Rumlow enlisted with Albert Malik, the communist Red Skull, in Algeria, serving him under the name Frag until he was sent to invade Arnim Zola’s Switzerland chateau. Ultimately the only team member to survive the assault, Rumlow there met and impressed the original Nazi Red Skull, Johann Schmidt; this Skull accepted Brock’s services, code-naming him Crossbones.
Red Skull sent Crossbones to observe Baron Zemo’s progress acquiring the Bloodstone fragments and to obtain them. He stowed aboard Captain America’s flagship, and entered Zemo’s ship to steal the Bloodstone fragments. He overpowered Diamondback, and shot a crossbow bolt that coupled with Captain America’s shield. Crossbones was forced to shatter the Bloodstone fragments when the alien entity known as the Hellfire Helix used it to take control of the body of Heinrich Zemo; the destruction of the Bloodstone discorporated the Hellfire Helix. Knowing that his master would be infuriated by the loss of the Bloodstone, Crossbones kidnapped Diamondback, taking her to Madripoor as bait for Captain America. He challenged Captain America to retrieve her, but the Captain defeated him, although Diamondback escaped, and the Red Skull ordered Crossbones to desist and return to headquarters. The Red Skull then ordered him to retrieve the Controller after the Controller’s breakout from the Vault. With the Machinesmith, Crossbones investigated the disappearance of the Red Skull.
Crossbones assembled the Skeleton Crew from the Skull’s henchmen and became their leader, searching for the missing Red Skull with them. They battled theBlack Queen and her Hellfire Club mercenaries. Crossbones enlisted the aid of psychic Tristam Micawber to locate the Skull. Upon finding him, Crossbones took the Skull to Skullhouse for convalescence. Crossbones always remained loyal to the Red Skull, even tracking him down when he is imprisoned and is left to die by Magneto.
He next attended AIM’s weapons exposition. He battled Daredevil during a failed assassination attempt against the Kingpin. He battled Bullseye during Bullseye’s failed assassination attempt against the Red Skull. He battled Captain America again and was defeated. He later recounts how he met the Red Skull. The Red Skull assigned him to discover who killed the Skull’s spare clone bodies. Alongside the Skeleton Crew, he battled the Schutzheilligruppe in an attempt to rescue the Red Skull but was captured. He was rescued from the Schutzheilligruppe’s custody by Arnim Zola’s fake Avengers. Crossbones was eventually fired for questioning the Red Skull’s decision to ally himself with the Viper.
Desperate to regain his position as leader of the Skeleton Crew, Crossbones kidnapped Diamondback, imprisoning her in an abandoned subway station and forced her into a brutal regime of combat training. Crossbones believed that he had brainwashed her into betraying Captain America, but Diamondback was actually laying a trap for Crossbones. She stole samples of Captain America’s blood from the Avengers’ mansion, then accompanied Crossbones to the Red Skull’s mountain fortress. The two were captured and imprisoned, and the Red Skull rehired Crossbones on a temporary basis. He was later attacked by Cutthroat, new leader of the Skeleton Crew, who feared that Crossbones will try to take back his position as the Red Skull’s right-hand man. Crossbones killed him, never realizing that Cutthroat was actually Diamondback’s older brother, Danny. Crossbones later stabbed Diamondback during her escape attempt, only to later save her with a blood transfusion in order to use her as bait, He was critically wounded by flying shrapnel during an assault on the fortress by Captain America and Falcon, and imprisoned.
Imprisoned in the Raft when Electro breaks the inmates out, Crossbones was seen fighting Captain America and Spider-Man. The latter kicked Crossbones in the face, knocking him out.
After he escaped from prison, Crossbones became a mercenary and assassin for a number of organizations, until he was rehired by the Red Skull, who was later apparently assassinated by the Winter Soldier. Crossbones and his new lover, Synthia Schmidt (the Red Skull’s daughter), began hunting the Soldier’s commander, Aleksander Lukin. They plotted to crash a stolen World War II era plane into the new Kronas Headquarters in London, only to have their plane destroyed by Red Skull’s Sleeper robot. While they escape the destruction of the plane, they found Agent 13, and are about to kill her, only to be stopped by the appearance of the Red Skull. They begin working with Red Skull/Lukin, whose minds both share Lukin’s body.
Following the Civil War storyline, Captain America and his Anti-Registration heroes surrendered to Iron Man and his Pro-Registration heroes. While being led from Federal Courthouse, Captain America was shot in the shoulder by Crossbones, who was taking orders from Red Skull. Crossbones tries to escape in a helicopter but was tracked by Falcon and the Winter Soldier. Winter Soldier then beat Crossbones into unconsciousness, while Crossbones simply laughed in his face. Falcon then turned Crossbones over to SHIELD custody.
In Fallen Son: The Death of Captain America, Wolverine along with Daredevil and the help of Doctor Strange, broke into S.H.I.E.L.D. to interrogate Crossbones and threatened to kill him. Crossbones revealed no knowledge of his hiring by the Red Skull. Wolverine left him a bloody mess on the floor after being convinced by Daredevil to spare his life.
S.H.I.E.L.D. Director Tony Stark arranged for Professor X to scan Crossbones’ mind for information, but Professor X found that someone (implied to be Doctor Faustus) had erased several parts of his memory in order to prevent such a scan. Sin and a new incarnation of the Serpent Squad have broken Crossbones free of S.H.I.E.L.D. custody. They then capture Winter Soldier when he confronts Lukin to find out his relationship with the Red Skull.
When Sin and the Serpent Squad attacked the Senate Building, Bucky Barnes (formerly Winter Soldier), arrived as the new Captain America. After battling and injuring many of the Squad, Crossbones attacked Barnes. After a brutal fight in which Crossbones launched Barnes out of the building. Bucky was saved by the intervention of Natalia Romanova, and he shot Crossbones several times in the chest. The gravely wounded Crossbones was then taken into S.H.I.E.L.D. custody once again.
At the start of the Heroic Age event, Crossbones has become a member of the new Thunderbolts team formed in the aftermath of Siege. Government agents, working with Luke Cage, add Crossbones to the team knowing that he cannot be reformed, hoping that his extreme methods will alienate the other Thunderbolt members and push them towards rehabilitation. During the team’s first mission, Crossbones was exposed to corrupted Terrigen Mists; during the events of Shadowland, Crossbones manifested the ability to fire a powerful, piercing beam of energy from his face, theorizing that this ability originates from his exposure to the Terrigen mists. He uses this ability to murder a police officer. Fearing that the Thunderbolts are close to being disbanded following Cage’s decision to leave, Crossbones attempted to escape alongside Ghost and Juggernaut. During the attempt, Crossbones used his new ability to fight an unsuspecting Steve Rogers. Crossbones was defeated and discharged from the Thunderbolts, after Ghost revealed his murder of the police officer. Crossbones is shown incarcerated in a padded cell wearing a straitjacket, apparently no longer able to use his energy beam.
During the Fear Itself storyline, Crossbones was constantly harassed while he was behind bars, because he was both a former Thunderbolt member and a neo-nazi. Shortly after when he was being beaten up by more thugs, the Juggernaut unintentionally causes a break out in the prison facility called the Raft. Man Mountain Mario (the cousin of Man Mountain Marko) helps defend Crossbones from the thugs. While the two of them were trying to escape, Mario told Crossbone about his grandma who helps criminals leave the border. Crossbones manages to escape and returns the favor by killing Mario to help with his escape. In Fear Itself: Youth in Revolt #2 he confronts some of the former Avengers Initiative members in New Jersey after he escapes the Raft. He fights Gravity, Frog-Man, Geiger, Scarlet Spiders, and Firestar; when he’s surrounded he tosses a grenade at Gravity but Geiger catches it and is seriously injured, creating an easy distraction for him to escape.
