Black Dwarf (Cull Obsidian)

Part 1: The Dossier: An At-a-Glance Summary

Part 2: Origin and Evolution

Publication History and Creation

Black Dwarf first appeared in a cameo in New Avengers Vol. 3 #8 (September 2013) before making his full debut in Infinity #1 (October 2013). He was created by writer jonathan_hickman and artists Jerome Opeña and Jim Cheung as part of their epic-scale Infinity crossover event. The creation of the Black Order, also known as the Cull Obsidian in the comics, was a significant addition to the Thanos mythos. Hickman conceived of them as Thanos's “evil Avengers,” a group of powerful and terrifying generals, each with a distinct personality and skillset, who could act as credible threats on a cosmic scale. Black Dwarf was designed to be the powerhouse of the group—the “Hulk” or “Thing” of the team—a being of immense physical strength and durability whose purpose was to break anything, or anyone, that needed breaking. His design by Cheung emphasized this, portraying him as a hulking, horned brute wielding a massive, technologically advanced axe, visually communicating his role as the battering ram of the Order.

In-Universe Origin Story

The origin of Black Dwarf, like the other members of the Black Order, is shrouded in a degree of mystery, built more on their actions than a detailed backstory. They are presented as beings found and “adopted” by Thanos from worlds he conquered, chosen for their immense power and unwavering loyalty born from fear and fanaticism.

Earth-616 (Prime Comic Universe)

In the prime Marvel comic universe, Black Dwarf's story begins as an established general in Thanos's army. During the Infinity event, Thanos launches a multi-front invasion of Earth while the majority of the avengers are off-planet dealing with the threat of the Builders. Thanos dispatches his five generals of the Black Order to different strategic locations on Earth to secure the planet and, secretly, to locate his Inhuman son, Thane. Black Dwarf was assigned what was arguably the most challenging target: Wakanda. This technologically advanced and well-defended nation, ruled by King Black Panther, was a fortress. Believing his overwhelming strength was sufficient, Black Dwarf led his forces in a direct frontal assault. This proved to be a catastrophic miscalculation. The Wakandan army, led by Black Panther and bolstered by the genius of shuri, mounted a ferocious and brilliant defense. They outmaneuvered Black Dwarf's forces, repelling his invasion and forcing him into a humiliating retreat. He was the only member of the Black Order to fail in his initial mission. Upon returning to Thanos's command ship, Black Dwarf faced the Mad Titan's wrath. For his failure, Thanos stripped him of his command and expelled him from the Black Order, leaving him to guard their base of operations. However, during the Avengers' counter-attack on Thanos's forces, Black Dwarf was given a chance to redeem himself. He engaged in a brutal battle against a contingent of Earth's heroes, including Ronan the Accuser. Despite his immense power, Black Dwarf was ultimately outmatched and killed when Ronan smashed his head with the Universal Weapon. Years later, during the Avengers: No Surrender storyline, Black Dwarf was mysteriously resurrected by the Grandmaster's cosmic brother, the Challenger, to serve in his new version of the Black Order. He fought against the combined forces of the Avengers and the Lethal Legion but was ultimately defeated once more. His final fate was being vaporized by the Grandmaster when the cosmic game concluded.

Marvel Cinematic Universe (MCU)

In the Marvel Cinematic Universe, the character's name is changed to Cull Obsidian, and the Black Order as a whole are referred to as the “Children of Thanos.” This name change was likely made to avoid confusion with eitri, the King of the Dwarves of Nidavellir who forges stormbreaker, and to streamline the terminology for a film audience. Cull Obsidian's origin is presented similarly to the comics: he is one of Thanos's adopted children, a loyal and fanatically devoted warrior raised to serve as a general in his armies. His history before his appearance in Avengers: Infinity War is not detailed, but he is shown to have a long-standing working relationship with his siblings, particularly ebony_maw. His story in the MCU begins in 2018 when he and Ebony Maw are dispatched to New York City to retrieve the Time Stone from doctor_strange. They arrive via a Q-Ship and immediately engage in a destructive battle with Tony Stark, Doctor Strange, wong, and Peter Parker's spider-man. Cull Obsidian proves to be a physical match for Iron Man and nearly overpowers him, but he is ultimately thwarted when Wong uses a portal to teleport him to a desolate, frozen landscape, severing his hand in the process. He later reappears with a prosthetic arm during the Battle of Wakanda, seeking the Mind Stone from vision. He leads a contingent of Outriders and engages multiple heroes. He has a notable confrontation with Bruce Banner, who is piloting the Hulkbuster armor. Despite Banner's inexperience with the suit, he manages to trap Cull Obsidian's prosthetic arm in the armor's gauntlet, activates its repulsor flight system, and sends the alien powerhouse rocketing into Wakanda's defensive energy shield, where he is graphically disintegrated. An alternate timeline version of Cull Obsidian from 2014 travels with Thanos's army to the present day in Avengers: Endgame. During the final battle at the ruins of the Avengers Compound, he is a major threat on the battlefield, rampaging through the heroes' forces. He is last seen being crushed underfoot by Scott Lang as giant-man. This marked the final end for the character in the MCU, as he was erased from existence along with the rest of Thanos's army by Tony Stark's use of the Infinity Gauntlet.

Part 3: Abilities, Equipment & Personality

Part 5: Iconic Events & Storylines

Infinity (2013)

This storyline marks Black Dwarf's debut and his most significant character arc. As Thanos invades an Avengers-less Earth, he sends Black Dwarf to conquer Wakanda. Confident in his power, Black Dwarf leads a direct assault, expecting to smash through the nation's defenses. However, he is met with fierce, technologically superior resistance led by Black Panther. The Wakandans use advanced energy shields, sonic weaponry, and strategic guerrilla tactics to decimate his forces. Black Dwarf himself is engaged and held at bay by T'Challa and the Wakandan army. Utterly defeated and repelled, he is forced to retreat, the only one of Thanos's generals to fail his mission. This failure leads to his disgrace and expulsion from the Black Order, a defining moment of humiliation for the character.

Avengers: No Surrender (2018)

In this weekly Avengers epic, Black Dwarf is resurrected by the Challenger, a cosmic being who has captured Earth to use it as a game board for a contest against the Grandmaster. Black Dwarf, along with the other original members of the Black Order, is reformed to act as the Challenger's primary fighting force. He participates in several large-scale battles against the assembled Avengers teams, once again serving as the group's muscle. His role in this story is primarily that of a powerful obstacle for the heroes to overcome. His journey ends when he is personally confronted and killed by Ronan the Accuser, a poetic echo of his first death at the hands of the same Kree warrior.

Avengers: Infinity War & Avengers: Endgame (MCU)

In the MCU, Cull Obsidian's role is spread across these two culminating films. In Infinity War, he is a primary antagonist. He first appears in New York alongside Ebony Maw to seize the Time Stone. His raw power is put on full display as he battles Iron Man and Spider-Man, nearly killing the former before being temporarily defeated by Wong. He returns for the film's climax at the Battle of Wakanda, where he is a relentless force on the front lines. His fight with the Hulkbuster is a key action sequence, ending in his memorable death as he is obliterated by Wakanda's force field. In Endgame, a version of Cull Obsidian from 2014 travels to the future with Thanos's army. He participates in the final, cataclysmic battle against the unified forces of the Avengers and their allies. He is shown rampaging across the battlefield, fighting Korg and clashing with Drax and Star-Lord before being unceremoniously stepped on and crushed by Giant-Man. His two distinct deaths in the MCU films solidified his role as a formidable but ultimately disposable threat.

Part 6: Variants and Alternative Versions

As a relatively recent addition to the Marvel mythos, Black Dwarf does not have as extensive a history of alternate versions as more classic characters, but he has appeared in other media.

Avengers Assemble (Animated Series)

Black Dwarf appears in the Avengers Assemble animated series as a member of Thanos's Black Order. His appearance and powers are largely consistent with his comic book counterpart, serving as the team's hulking brute. He acts as a physical threat for the Avengers, particularly the Hulk and Thor, to overcome. The animated series streamlines the Infinity storyline, with Black Dwarf and the Order serving as recurring antagonists for the season.

Marvel: Ultimate Alliance 3: The Black Order (Video Game)

The character, named Cull Obsidian as in the MCU, plays a significant role as a primary antagonist and boss in this Nintendo Switch exclusive title. The game's story is a loose adaptation of the Infinity saga, with the Black Order seeking the Infinity Stones on behalf of Thanos. Cull Obsidian is encountered as a boss multiple times, often paired with another member like Ebony Maw. His moveset in the game reflects his immense strength and his MCU weapon, featuring heavy smashing attacks, charges, and area-of-effect ground pounds, making him a challenging obstacle for the players' team of heroes. His prominent role in the game, which is even subtitled The Black Order, helped to further cement his status as a key member of Thanos's inner circle for a wider audience.

Notes and Trivia

1) 2) 3) 4) 5)

1)
Black Dwarf's name in the comics is a direct astronomical reference. A “black dwarf” is a theoretical stellar remnant, specifically a white dwarf that has cooled sufficiently that it no longer emits significant heat or light. This naming convention is shared by another Black Order member, Supergiant.
2)
The character's name was changed to Cull Obsidian for the MCU. “Cull” means to selectively slaughter or remove from a group, and “Obsidian” is a dark, volcanic glass. The name effectively translates to “Slaughterer of Stone,” reflecting his role as a powerful destroyer. The name “Cull Obsidian” is also an alternate name for the Black Order itself in the original Infinity comic storyline.
3)
Creators: Jonathan Hickman, Jerome Opeña, and Jim Cheung. First appearance: Infinity #1 (October 2013).
4)
In the comics, Black Dwarf is the brother of Corvus Glaive. This familial connection is not mentioned or implied in the Marvel Cinematic Universe, where the members are all referred to as “Children of Thanos.”
5)
Despite his immense power, Black Dwarf holds the dubious distinction of being the first member of the original Black Order to be defeated in the Infinity event, and he has died twice in both the comics and the MCU, making him arguably the least successful member of the group.
