Origin

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.

Creation

Blockbuster was created by Louise Jones Simonson and Walter Simonson in 1986 and first appeared in X-Factor # 10.

Major Story Arcs

Mutants Massacre

Blockbuster first appeared in comics when, on Sinister's orders, the Marauders massacre the underground community of mutants known as the Morlocks. In the course of the massacre, the Marauders, including Blockbuster, clash with various superhuman champions, including the mutant adventurers known as the X-Men. The Norse god Thor is summoned to the Morlock Tunnels by his ally, the frog Puddleglup, happens upon Blockbuster following his torture of the mutant Archangel. Thor kills Blockbuster to avenge the innocent Morlocks he has slain. Thor then burns his remains, along with those of the slaughtered Morlocks. 
 
Sinister however uses his technology to clone the Marauders. Blockbuster and other previously-slain Marauders return during the demonic invasion of Manhattan referred to as the Inferno. Blockbuster is among the Marauders set by Sinister to defend his orphanage/laboratory headquarters. Blockbuster is slain by the mutant Havok, who had, along with most of the X-Men, been tainted by the demonic invasion, becoming more bestial and aggressive.

Though the X-Men discovered and deactivated many of Sinister's Clone Vaults after the events of the crossover saga X-Cutioner's Song, Blockbuster returned with the other original Marauders, when they attacked the X-Mansion.

Messiah Complex

Blockbuster's body is seen later being "eaten" by Predator X after he and the rest of the Marauders arrive at an Alaskan town. The Marauder's goal had been to find a mutant baby, a current rarity; they had also encountered the Purifiers, another group searching for the child. It is unknown if Sinister's cloning samples survived after M-Day, and whether he will be cloned again

Astonishing X-Men

More recently, Blockbuster was seen, again cloned, when fighting some of the X-Men. He was quickly dealed with and killed once more.

Powers

Blockbuster possessed various superhuman physical attributes as a result of natural mutation and, possibly, from augmentation from Mr. Sinister. Blockbuster possessed great superhuman strength, the exact limits of which were never defined. However, Blockbuster was sufficiently strong enough to lift at least 70 tons. Blockbuster's advanced musculature generated considerably less fatigue toxins during physical activity than the musculature of ordinary humans. He could physically exert himself at peak capacity for about 24 hours before the build up of fatigue toxins in his blood began to impair him. Blockbuster's bodily tissues were much harder and more resistant to physical injury than those of a normal human. He could withstand great impact forces, powerful energy blasts, exposure to extremes of temperature and pressure, and falls from great heights without being injured.
