Deathshead

The Deathshead was a Xyston II-class Star Destroyer of the Coalition of the Red Star that was the first of the new ships to launch from the Moon. It was infamous for destroying the planet Remnant.

History
"Send the Deathshead to a world they know. Let it burn."

―Victor Nevarez gives the order for Remnant to be annihilated

The Deathshead was the only Star Destroyer of its class that was part of the Immortal Armada of Darth Trethium. On the orders of Victor, the Deathshead was the only starship to successfully launch from the Moon while the remainder of the armada was stationed on Exegol, their numbers are too expansive to all leave the planet simultaneously without being guided out by a navigational beacon.

Nevarez later ordered Grand Admiral Eilert Salazar to choose a planet with connections with the Grand Alliance to destroy as a show of force. The frigid world of Remnant was chosen, and the Deathshead used its upgraded axial superlaser to obliterate the entire planet. After this, the Star Destroyer fled back to Exegol to join the invasion fleet. As the armada prepared to invade Earth, the USS George W. Bush with the Earth Defense Fleet, and eventually the Free Worlds Fleet, came and destroyed nearly all of the starships, including the Deathshead and its crew.
