A Shadow Hybrid was a prototype starship based on Shadow technology, built by a secret division of Earthforce. It was the first ship to have original Shadow technology in cooperation with Earth Alliance capabilities, equipped with a hybrid version of the Shadow Pulse Ray.
In 2259, one such ship was witnessed to have destroyed the EAS Cerberus, leaving then Ensign Matthew Gideon as the only survivor. In 2267, a modified version of that ship was detected by the Excalibur after it attacked and destroyed a civilian ship in Sector 840. The Excalibur eventually chased the damaged ship down and destroyed it in an asteroid field. Later that year, the Excalibur tracked a carrier wave used by the ship back to a home base in Sector 420.
