History
Xartan Ships were a type of spaceship that made up the Xartan attack fleet. One such ship had landed on Earth and sent out numerous Carbon Copy Men to mimic and replace various key people in New York City, also capturing Mayor Harris and Jane Foster. Thor attempted to investigate the ship but was magnetized to its hull and lost his grip of Mjolnir which caused him to revert to the mortal Donald Blake and himself be captured and brought aboard the ship.[1]
