King Ra is the ruler of the Land of Fairies in the potentially imaginary realm known as Nowhere. When he heard that Jimmy Jupiter was the only boy of his generation that could mentally project his body into their realm, he sent his aid the Blue Fairy to bring the boy so that the he could show Jimmy the wonders of his realm.
Jimmy lost his way, however when he eventually met with the King, the King made good his offer. After showing Jimmy the royal candy garden he charged Fairy Delight to showing Jimmy around the kingdom.
His subsequent activities are unknown.
