Black Dwarf was a member of the Black Order. Alongside the rest of the Order, he was hired by the Collector as security for his vast collection. Black Dwarf found himself facing off against Thanos, though he was killed by Nebula using the stolen Embers of Genesis.
Black Dwarf and the rest of the Black Order were hired by the Collector, who seized an opening in the power vacuum when Thanos changed his ways. Under Tivan, Dwarf and the others were given security duty, protecting the museum and the many items within it, Tivan's vast collection.[1]
In 2008, Black Dwarf was on guard duty alongside his brother Corvus Glaive, when the pair were alerted to a disturbance. Upon investigating, they found the Ravagers and realized it was a diversion. Later, as the team attempted to make their escape, having stolen the Embers of Genesis, Black Dwarf gave chase alongside Proxima Midnight.
The pair came to face Thanos, Dwarf marching towards the Titan as he dispatched the numerous Sakaarans. Dwarf swung with heavy blows, Thanos catching his chain hammer with a smile and pushing back against it, landing punches on Dwarf. However, the Titan was thrown off by Midnight, allowing both Black Dwarf and her to viciously beat Thanos. Black Dwarf then slammed Thanos to the ground, and began smashing the chain hammer repeatedly against him. He stopped as Proxima stepped over, ready to execute the Titan, but both were suddenly stopped in their tracks by the arrival of Nebula, who took down Proxima.
Black Dwarf's final moments
Black Dwarf lunged forwards, grabbing Nebula by the throat, roaring as he prepared to crush her. Before he could, however, Nebula opened the canister containing the stolen Embers of Genesis, and allowed a couple of its spores to fly free, right into Black Dwarf's open mouth. Dropping Nebula and coughing, Dwarf had little time to realize what had just happened before the spores activated, blowing Black Dwarf apart as plants burst out, growing at a rapid pace and transforming all of Knowhere into a massive botanic garden.[1]
The character is referred to as Black Dwarf, his original name from the comics, as opposed to Cull Obsidian, the rename his main universe counterpart was given.
