Rokk Krinn comes from planet Braal, where everybody has magnetic powers to defend themselves from the local metal-based fauna.
Some time later, Rokk was traveling in a passenger ship that also carried philantropist RJ Brande. When telepath Imra Ardeen found about a plot to assassinate Brande, Rokk and Garth Ranzz stopped the attempt on Brande, who suggested the three teenagers to form a team, so they became the founding members of the Legion of Super-Heroes, Rokk as Cosmic Boy, Garth as Lightning Lad, and Imra as Saturn Girl.
- Cosmic Boy is the second Legion of Super Heroes minifigure, after Lightning Lad.
