ISS Belligerent

In the dark mirror universe, the ISS Belligerent was an Excelsior-class battle cruiser starship in service to the Terran Empire in the 24th century.

In 2366, the Belligerent crossed over to the alternate mirror universe. There, she set a trap for the ISS Enterprise-D. When the Enterprise arrived, the Belligerent was waiting for her. What the Belligerent did not know was that the Enterprise did not come alone. She was accompanied by a fleet of Terran Imperial starships and also by Federation starships from the primary universe led by the USS Enterprise-D. After a battle, the Belligerent was destroyed by the combined forces of the Empire and the Federation.
