Bio: Dietzel was injected with the ZXX serum, developed to try and replicate the effects of the Super Soldier process that produced Captain America.
Was forced into a confrontation with Captain America at an orphanage and was on the brink of overpowering Captain America when a boy from the orphanage ran up and beat on him, trying to make him let Captain America go. Dietzel fled, and was told by Silas X. Cragg (the man who invented the ZXX serum) that the boy at the orphanage was in fact Dietzel's son.
Renaming himself Blockbuster, Dietzel sought out wealth so that his son would never have to sink to the depths that he had. He robbed a bank which brought him into a confrontation with Omega The Unknown. After a struggle, Omega The Unknown let Dietzel leave with the money after he explained it was for his son.
Later, Dietzel robbed a diamond store and was once again brought into confrontation with Omega The Unknown when a reward was offered for his caputre. Dietzel was on the verge of snapping Omega's neck when he was incinerated from behind by a blast from the Purifier Gun of The Foolkiller, who had judged Dietzel as a fool.
