Fictional character biography Mark Desmond The first Blockbuster was Mark Desmond, a chemist who desired to increase his physical strength. Experimenting on himself, he succeeded in making himself stronger and taller, but as a side-effect of the process he also became almost mindlessly aggressive. The mentally debilitated Desmond was cared for by his brother Roland, a local criminal, who kept their mother from discovering what Mark had done to himself. Roland manipulated his brother into committing crimes on his behalf until they came into conflict with Batman and Robin. Bruce Wayne had once rescued a young Desmond from drowning, and he discovered that he could calm the enraged adult Desmond by removing his cowl and showing his face. Desmond later found himself clashing with Batman on various occasions. Blockbuster absorbed energies from the Alfred Memorial which gave him some powers and was once substituted for the super-strong undead villain Solomon Grundy from Earth-Two due to a machine that was substituting people from both Earths. Green Lantern caused him to fight Solomon Grundy, leading to them both briefly getting the fight knocked out of each other. While Solomon Grundy was taken back to Earth-Two by the Justice Society of America, Blockbuster was handed over to the police by the Justice League. Blockbuster joined the Secret Society of Super Villains briefly for a battle with the Justice League. King Kull enlisted Blockbuster, Penguin, Queen Clea of Earth-Two, and Ibac of Earth-S to wreck Atlantis and use a cloud to sink islands. They are thwarted by Superman, Wonder Woman of Earth-Two, Green Arrow, and Spy Smasher of Earth-S. Later, Amanda Waller recruited Desmond for her revived Suicide Squad. He was killed fighting Darkseid's creation, Brimstone. In 2011, "The New 52" rebooted the DC universe. Mark Desmond is
