Lion Boy is a young male child who looks like a lion. He is partnered up with his pet Jarib in the circus. He found Jarib when he was a cub and has been teaching him how to roar ever since. He believes that his friend can roar that he is willing to disobey the ringmasters orders to do a Cowardly Lion show for him. He helped Marco and his friends when they where traped in the desert. He took them to the circus so they can get out of the sun. Ringmaster did not like them for not being payed guests but Lion Boy insists that they are his guests. At the end Lion Boy stood up for Marco and his friends against the Head Soldier and it was when he was shoved away that Jarib got enough courage to roar a mighty lions roar.
