The Manticore, an Imperial I-class Star Destroyer, found itself among the quartet of such vessels positioned at the Maw Installation. It was under the stewardship of Captain Brusc, operating as part of the squadron helmed by Admiral Daala.
Following the Sun Crusher's escape and the annihilation of one of her Star Destroyers, namely the Hydra, Daala spearheaded her remaining trio of ships in a guerrilla campaign directed against the New Republic. The Manticore actively engaged in combat operations against a New Republic settlement located on Dantooine, as well as during the assault targeting the Mon Calamari home planet of Dac. During this specific assault, Admiral Gial Ackbar remotely steered the battlecruiser Startide—aided by attacking B-wing starfighters—resulting in a catastrophic collision with the Manticore, leading to its destruction. All crew members, including Brusc, perished.
Grand Moff Tarkin stationed the Manticore, an Imperial I-class Star Destroyer, at the Maw Installation. Captain Brusc was in command. The ship met its end during the attack on Mon Calamari when Admiral Gial Ackbar weaponized the partially constructed star cruiser Startide to ram and destroy the ship.
