The Starchaser was the spaceship with which Rug Yorkvain participated in the Toro Regatta during the eponymous episode. The ship was destroyed during the race.
The ship had a drop drive, just like the Crimson Light. It was armed with laser cannons located at the rear, but these were taken out by Fox and Little Cato.
The ship was blown up by Rug himself after Gary Goodspeed and Ash Graven boarded it in an attempt to steal the Nymerian Cube.
