The Merciless was a Venator-class Star Destroyer that was assigned to Drewika Zirátæ during the Clone Wars. The ship was supposed to be Zirátæ's flagship, but it was largely replaced by Zirátæ's personal ship, the Victory. The ship did participate in several important battles, including the Battle of Coruscant. The ship was destroyed during the Battle of Utapau, but its legacy carried on its name. Zirátæ's Executor-class Star Destroyer was named the Merciless in honor of this ship.
