Darren Cross

Darren Cross was a self made millionaire, he created and headed his company, Cross Technological Enterprises, and made it a success to rival the top competitors. However, Darren was diagnosed with a rare heart condition. He used his own technology to create an experimental nucleorganic pacemaker to save his life. Although a success, the nucleorganic pacemaker mutated Darren's body to and gave him superhuman abilities. A side-effect of the mutation was that Darren would quickly overuse and burn out his heart. Multiple heart transplants were performed, but each heart was removed when overused. Desperate, he kidnapped heart surgeon Dr. Erica Sondheim to replace his damaged heart. He also kidnapped 'donors' from slums.

Darren Cross was later recruited by the Homines Verendi to attack the Marauders.
