a patient of Dr. Phayne's. He lives on the estate and at night he undergoes procedures to enhance his intelligence. He is exposed to small amounts of a green compound intravenously. An accident is caused by a new patient believing he is in pain and the cascade of green liquid overdoses Desmond and creates an explosion. The overdose exposes a super-strong man calling himself Blockbuster. He rampages from the building in pain and knocks an attacking Hawkman unconscious. Blockbuster was later mind-controlled by Necromancer to help her steal an artifact from a Washington D.C. museum, which brought the attention of Hawk and Dove. They teamed up with Batman and Robin to stop Blockbuster and Necromancer. Mark Desmond later appears as a member of the Secret Society of Super Villains upon having been recruited by Outsider. When Catwoman breaks out of Arkham Asylum, Mark Desmond and Signalman confronted Catwoman on a rooftop, which ended with Catwoman being knocked out. Roland Desmond Roland Desmond became the second Blockbuster after a severe illness forced him to be treated with experimental steroids.

Roland's plan was to build a criminal empire in Blüdhaven that would eventually enable him to extend his dominion over Gotham, Star City, Metropolis, and New York's underworlds. For that purpose, he bought the corrupt elements of the city's police department, most notably Police Chief Redhorn and Inspector Dudley "Deadly" Soames. Despite his swift and vicious consolidation of power, Blockbuster's hold on Blüdhaven's organized crime was nevertheless weakened by the intervention of the city's new protector, Nightwing (Dick Grayson, the former Robin), who, with Oracle's help, foiled Desmond's plans at every turn. Oracle often removes money from Blockbuster's accounts and he has a man working to stop and find Oracle,
