A Little History
As a member of the Braalian race, Cosmic Boy has the ability to control and manipulate magnetic forces. However, his control of magnetics is far superior to the others from his home planet.
At the tender age of 15, Rook left his home world for Earth. He did this because he saw that his parents, Ewa and Hu Krinn, were constantly struggling to find and keep work on Braal.
Shortly after arriving on Earth, Rook, along with other heroes Garth Ranzz and Imra Ardeen, successfully prevented the assassination of the well-known billionaire, R.J. Brande.
Brande was different from the other inhabitants on Earth. Unlike most Earth dwellers, Brande was actually a shapeshifter in disguise known as Ren Daggle. As a consequence of a fever known as Yorggian Fever, Daggle was unable to shape back and therefore stuck in human form.
Brande, impressed by the three, offered them the chance of a lifetime. He commissioned them to become a group of heroes known as the Legion of Superheroes and for Krinn to be their leader. Now the leader of the Legion of Superheroes, he took on the moniker of Cosmic Boy. The rest, as they say, is history.
Over the course of the next couple of years, Cosmic Boy transformed himself into one of the most respected leaders in DC. With him at the helm, the Legion of Superheroes grew from just three members to over fifteen during those few years.
