Blockbuster was one of the Marauders involved in the massacre of the Morlocks. He helped Harpoon and Sabretooth ravage Angel's wings before encountering Thor. During a brief and vicious battle, Blockbuster succeeded in breaking Thor's right arm. However, Thor violently hurled his enchanted hammer Mjolnir at Blockbuster and killed him.
A clone of Blockbuster was used by Mister Sinister when the Marauders confronted the X-Men near the Morlock tunnels again months later. However, he was corrupted by the influence of the Inferno and became demonic.
While tracking Threnody and X-Man, he was killed by Arclight, lured into attacking him by Grey's illusions.
He was seemingly cloned again and continued to serve Sinister until he was killed during their raid into Alaska in search of Hope Summers.
Somehow, he came back to life again and rejoined the Marauders gathered by Da'o Cao Mạnh seemingly against his will as the others, and attacked the X-Men. He was eventually found fleeing out, terrified, but was killed by Warbird before Wolverine could stop her, as he wanted information.
After being resurrected, the Marauders struck off on their own, once again massacring the Morlock population. This lead an angered Chamber, their new leader, to rejoin the X-Men. When the X-Men re-encountered the Morlocks, the Marauders fought briefly, but ultimately surrendered, professing their innocence. Not believing them, Chamber burned them to death with his psionic flame.
Following the foundation of a mutant state in Krakoa by the hand of Charles Xavier and his allies, Blockbuster, and the other Marauders remained in the clone farm where they had been reborn. They were enslaved and held captive by the Goblin Queen, who planned to use them as foot soldiers for an invasion of Krakoa. Blockbuster's former teammate Greycrow and his new team the Hellions destroyed the clone farm and killed Madelyne. Before leaving, Greycrow killed Blockbuster, freeing him to be resurrected by the Five.
