When superheroes began to appear around the world, Earth Strike was one of the first to appear in Africa. Together with seven other African superheroes, he founded the group known as the Kingdom, and helped to end a revolution that was tearing through the Congo. But after operating for five years, the team disappeared.

Earth Strike retired after the Kingdom's disappearance, returning to his civilian identity, Dede Yeboah. He became an agricultural attache to the Congolese government. Eventually, he was located by the villain called Massacre, and was apparently murdered. His wallet was found among a group of drug dealers who had been butchered by Massacre.
