Billy Mar-Vell is actually a young boy who, when he shouts the word "Kree!", transforms into the super-scientifically enhanced adult hero named Captain Marvel.
History
His fellow members in the Judgment League Avengers only know the adult Captain Marvel, and are not aware of his secret identity or true age.
After Angelhawk, Canary, and Goliath found Super Soldier, Captain Marvel soon joined and formed the Judgment League Avengers. He was transported by Dr. Strangefate with other members of Judgment League Avengers to battle Thanoseid. When Mariner was accused of blowing up oil freighters the U.S. government branded him an eco terrorist and Captain Marvel and other non metamutant members of the JLA captured him and imprisoned him without a trial. When the other meta mutant members of the JLA found out about Mariner they broke him out under Mister X but Captain Marvel and the other non metamutant members of the JLA were not going to give up without a fight.
