Blockbuster

Mark Desmond is the former head of Cadmus Labs' Washington, D.C. facility. He later used Project Blockbuster to mutate himself into a powerful monster, referred to by Superman as "that Blockbuster creature".

Personality
As Mark Desmond he is a strict stern man who uses G-Gnomes to manipulate his staff and security officers while willingly conducting illegal genetic experiments in the underground Cadmus labs. He is manipulative and very impatient yet also very protective of his labs and experiments. As Blockbuster he is a raging monster apparently incapable of human speech.

Appearance
For a standard caucasian male, Mark Desmond had long hair which was tied back in a pony tail. He wore a standard white lab coat, glasses and had slight wrinkles on his face and streaks of white in his hair indicate he is over thirty.

History
Mark Desmond was an agent of Cadmus and, given the circumstances, probably knew about 'the light' as the board called it. He was soon appointed as head of Cadmus' genetic labs in DC. Then, after a small fire broke out at the ground level of the Cadmus facility, three sidekicks breached security and freed his top secret Project Kr also know as Superboy. Although Superboy turned on his would be captors, Aqualad was able to communicate with him and get him to change sides just as Desmond was about to clone the three before killing them. After an extended chance through the Cadmus facility, Desmond was forced to use project Blockbuster to restore 'order' to Cadmus. He fought the newly formed Young Justice team to a standstill before Robin devised a plan to electrocute him and bring the roof of Cadmus' ground level down on top of him. He is last seen being carried away, still unconscious, by the Green Lantern duo (John Stewart and Hal Jordan).
