Roland Desmond became the second Blockbuster after a severe illness forced him to be treated with experimental steroids. In the wake of a detonation of the Dominator's gene-bomb in Earth's atmosphere, Roland was wracked with seizures and rushed from prison to a hospital. Steroid treatments reacted with his genetically altered cell structure to enable him to become a hulking creature like his brother. Unlike, Mark, however, Roland had control of his transformations—and his mind. The new Blockbuster soon lost his ability to revert to normal but was captured before he could do anything about it he had ran wild in the Southwest, but Batman and Starman brought his rampage to an end.
