Crossbones

Brock Rumlow grew up on the streets of New York’s Lower East Side, leading the violent Savage Crims gang. His cruelty showed early when he assaulted a fifteen-year-old girl named Rachel Leighton. After killing her brothers in retaliation for their defense of her, Brock fled and joined the Taskmaster’s school for criminals. He quickly rose through the ranks, becoming an instructor under the alias “Bingo Brock.” His skills as a fighter, strategist, and killer made him a valuable mercenary, and he eventually found work under the communist Red Skull, Albert Malik, in Algeria. After surviving a failed raid on Arnim Zola’s stronghold in Switzerland, Rumlow impressed Johann Schmidt, the original Nazi Red Skull, who took him in and gave him the codename “Crossbones.”

As Crossbones, Brock became one of the Red Skull’s most trusted operatives, undertaking missions that required precision, violence, and loyalty. He first crossed paths with Captain America while searching for the fragments of the mystic Bloodstone, stealing two shards and later destroying the alien Helix that threatened to resurrect Baron Heinrich Zemo. Later, he kidnapped Diamondback—Rachel Leighton, his former victim—using her to bait Captain America into a trap in Madripoor. Though nearly killed when Cap left him atop a live bomb, Crossbones escaped on the Red Skull’s orders. He went on to work with figures like the Controller and led missions to manipulate and capture powerful individuals, including hypnotizing Namor and orchestrating prison breaks at the Vault.

As the leader of the Red Skull’s elite “Skeleton Crew,” Crossbones assembled dangerous allies like the Controller, the Voice, and Mother Night to serve their master. He led operations against the Hellfire Club’s Selene, clashed with the Avengers, and hunted down the Red Skull when Magneto captured him. Crossbones also fought to eliminate criminal rivals such as the Kingpin but failed due to Typhoid Mary’s intervention. His loyalty was unwavering, though he was temporarily fired after questioning the Red Skull’s alliance with Viper. Operating independently, he briefly worked for a Chicago drug lord and later kidnapped Diamondback once again, imprisoning and torturing her in an attempt to break her loyalty to Captain America.

Eventually returning to the Skull’s service, Crossbones continued as an enforcer until he murdered the new Skeleton Crew leader, Cutthroat, after learning of a plot against him. Captured during a raid led by Captain America and the Falcon, he convinced authorities of his “rehabilitation” by helping stop a terrorist cell, only to escape and resume his mercenary work. He briefly worked for Hydra, bombing New York’s embassy row, and later took contracts such as an assassination attempt on Gambit before rejoining the Red Skull.

During the Red Skull’s later schemes involving Aleksander Lukin and the Cosmic Cube, Crossbones kidnapped and brainwashed Sin, the Skull’s daughter, turning her into his loyal partner. Together, they executed the Red Skull’s most notorious plot—the assassination of Captain America. Working with Doctor Faustus, who manipulated Sharon Carter into shooting Cap, Crossbones acted as the sniper who fired supporting shots during the chaos. Captured soon after, he was interrogated by Wolverine and Daredevil aboard the S.H.I.E.L.D. Helicarrier before escaping.

Crossbones later aided Norman Osborn and the revived Red Skull in an attempt to transfer the Skull’s consciousness into Steve Rogers’ body. When the plan failed and Rogers was restored to life, Crossbones and Sin fled. He was later recruited by Luke Cage into the Thunderbolts, where he briefly gained energy-based powers after exposure to Terrigen Mist, though they were later lost. Despite his forced service, his violent nature and hatred for Captain America remained unchanged.

In later years, Crossbones continued to operate as a killer-for-hire. He took part in missions involving virus outbreaks, massacring survivors to ensure his objectives, and betrayed his employers by killing his targets after extraction. During the Serpent War, he escaped from the Raft prison and joined Sin in a global hunt for mystical hammers tied to the Worthy. He battled Namor and Luke Cage, was nearly killed by Wolverine, and later revived by Daimon Hellstrom to serve the D.O.A., a death-worshiping cult.

Crossbones’ career persisted as he operated in conjunction with Hydra’s new leadership. He appeared at Doctor Octopus’ facilities during the “Ends of the Earth” event, later hunting symbiote hosts such as Mania under the D.O.A.’s orders. When Hydra reemerged under Baron Zemo and the brainwashed Captain America, Crossbones was among its most ruthless lieutenants. He fought Sam Wilson and Ian Zola, engaged the new Captain America in Florida, and was captured in S.H.I.E.L.D.’s reality-altering community of Pleasant Hill. During the uprising there, he nearly killed an aged Steve Rogers before the sentient Cosmic Cube, Kobik, restored Rogers to his prime.

Following these events, Crossbones co-founded a new Hydra faction with the Red Skull and Sin. During Hydra’s takeover of the United States under the “Secret Empire,” he and Sin commanded one of the regime’s super-prisons, enforcing the Skull’s brutal rule.

Appearance: Crossbones has a heavily muscular and rugged physique, his upper body broad and defined with bulging arms and dense, veined muscle structure across his shoulders and biceps. He wears a black tactical outfit with segmented armor plates and ribbed padding covering his torso and legs. The material is matte and ridged in texture, highlighted by narrow white streaks that catch the edges of the folds. His chest armor is reinforced and form-fitting, with thick straps running diagonally over his shoulders and crossing his back. Around his waist is a dark brown utility belt equipped with small pouches and holsters, the flaps fastened securely with buckles and rivets. His pants are a continuation of the same armored material as his upper suit. His head is covered by a black and white mask that fits tightly around his head. The mask is patterned like a skull, with white sections forming angular shapes over his forehead, nose, and cheek areas, while the rest remains deep black. He wears fingerless black gloves, the leather smooth over his palms but creased along the back of his hands and knuckles.

Personality: Crossbones is ruthless, aggressive, and unapologetically violent, defined by his absolute loyalty to power and a deep enjoyment of combat. He thrives in chaos and treats violence as both art and language, favoring brute force and intimidation over subtlety. Cold, disciplined, and efficient, he operates with the mindset of a soldier bred for survival and dominance, never hesitating when a kill is required. Though outwardly crude and sardonic, he possesses a sharp tactical mind and a predator’s awareness, always reading his environment for weakness. His loyalty is earned through respect and strength rather than ideology—he follows leaders like the Red Skull not out of faith, but because they share his belief that fear and control are the truest forms of order. Underneath his hardened exterior lies a deep resentment toward weakness, compassion, and morality, all of which he sees as obstacles in a world where only the ruthless endure.

Crossbones possesses enhanced physical conditioning that places him far above the capabilities of ordinary humans. His body has undergone unknown augmentations that drastically increased his muscle mass, strength, stamina, and overall performance. Daredevil once compared his physical prowess to that of Captain America, as Crossbones exhibits superior durability, reflexes, and endurance. His metabolism is also enhanced, granting him the ability to recover from fatigue more rapidly than normal humans. His strength is at the peak of human potential, allowing him to lift up to 800 pounds and crush the neck of a mutated opponent with ease. His durability enables him to withstand blows that would incapacitate most fighters, including being smashed through a solid brick wall by the Winter Soldier. Despite his bulky frame, Crossbones moves with surprising speed, capable of sprinting between 32 and 36 miles per hour, and his enhanced stamina allows him to perform at maximum intensity for up to an hour before tiring. His reflexes are also highly developed, allowing him to evade multiple gunshots at mid-range.

In addition to his physical enhancements, Crossbones is a master martial artist and one of the world’s most skilled hand-to-hand combatants. He has extensive training in military fighting systems, street brawling, and multiple martial arts disciplines. His mastery of combat led the Taskmaster to recruit him as an instructor at his school for criminals, where Crossbones trained others in advanced techniques. He is also an expert marksman, proficient with firearms, throwing knives, and his signature crossbow. Beyond combat, Crossbones possesses a brutal talent for interrogation and torture, having successfully brainwashed and reconditioned others, including Sin and nearly Diamondback. His skills extend to piloting, and he is capable of operating various aircraft with military precision.

Crossbones’ arsenal includes a wide variety of deadly equipment and weapons. He carries communication devices, one of which is integrated into his gauntlet for field operations. His standard loadout consists of pistols, rifles, a collapsible crossbow, spring-loaded stiletto blades mounted in his gauntlets, and an assortment of explosives and poisoned knives. His preferred means of transportation are typically the Red Skull’s private jet or helicopter. Despite his advanced combat capabilities and tactical discipline, Crossbones’ greatest flaw is his psychopathy—his violent impulses, cruelty, and utter disregard for morality make him as unstable as he is dangerous.
