Blockbuster is a member of the Marauders, a team of superhuman assassins brought together by the mutant thief Gambit when he was in the employ of the enigmatic Mister Sinister. On Sinister's orders, the Marauders massacred the underground community of mutants known as the Morlocks. In the course of the massacre, the Marauders, including Blockbuster, clashed with various superhuman champions, including the superhuman mutant adventurers known as the X-Men.
The Marauders, including Blockbuster, originally died during the demonic invasion of Manhattan that came to be known as the "Inferno", but Sinister has the technology to continually clone the Marauders thanks to his retaining samples of their DNA. Recently, Blockbuster was killed by Predator X.
