Rokk Krinn

His parents struggling for work on the impoverished, metallic world of Braal, Rokk Krinn left at the age of 15 for the mother world of Earth to find work to assist his family. Following his flight, Krinn helped save billionaire R.J. Brande from an assassination attempt along with Garth Ranzz and Imra Ardeen. Brande was impressed by the youth and offered them work founding a team of young super-heroes. Rokk accepted and became Cosmic Boy, the team's first leader.
