| Origin |
Having highly developed
magnetic skills at an early age Rokk Krinn became
Braal's greatest professional MagnoBall player, enabling him to support
his impoverished family. His many fans nicknamed him "Cosmic
Boy," a title he continues to use with pride.
On a galactic MagnoBall promotional tour, Krinn, along with Imra Ardeen (Saturn
Girl) and Garth Ranzz (Lightning Lad), prevented the assassination of
interplanetary entrepreneur R.J. Brande. Impressed by the teens'
bravery, the industrialist convinced them to form the
Legion
of Super Heroes. |
