Early Life

Though Rokk is a Braalian, he was not born on Braal; he was born on Earth before his family moved back to Braal. This is why he has more control over his magnetic abilities than other Braalians.[1]

 

Rokk's parents were struggling for work on the impoverished world of Braal, so he left at the age of fifteen for Earth to find work to assist his family. On a spaceship trvelling to Earth helped save billionaire R.J. Brande from an assassination attempt along with Lightning Lad and Saturn Girl.[2]-[3]

 

The Founding of the Legion

Brande was so impressed with the teens' bravery, that he petitioned the United Planets to form a Legion of Super-Heroes – an ever-growing cosmic team inspired by the exploits of 20th century teen super-heroes Superboy and Supergirl. Rokk became became Cosmic Boy, the team's first leader. Eventually they would travel backwards in time to the 20th Century to meet Superboy and Supergirl and welcome them into their ranks.[4]-[5]-[6]

 

During his first year worked as a leader dedicated and being a figurehead as a founding member and the first leader even when just another active member. After sometime, a romance blossomed between Lydda Jath alias Night Girl of the Legion of Substitute Heroes.

 

After time he raised enough funds to bring his family to Earth, but a firebomb went off in the neighbourhood where they lived. His whole family was injured and his mother later died. This led Rokk to almost kill this also encouraged his younger brother, Pol Krinn, to join the Legion Academy as Magnetic Kid. When he agreed with his fellow founders that they were getting old and it was time they resigned, Rokk was pushing for his brother to be elected to the team in his place.
