The Screaming Skulls were a mercenary and smuggling band who would do anything that made money. They seemed to have a "uniform" of a single earring. In 2494, they were led by Declan Moore and his second-in-command, Jack. They owned a freighter called the Privateer. Under his leadership, they declared they wouldn't hide their identity. They often hung out openly in clubs such as "The Pit". By 2502 they were led by Wendell Carver and his assistants, Dasch and Mithras. They owned a ship called the Cutlass which bore a strange alien artifact.
