The Megacruiser is a very advanced spaceship that originally belonged to Slix Vigma.
Little is known about the exact origin of the ship or Slix Vigma, but by its debut in Grudge Match, it already fulfilled its role as a space coliseum. Slix Vigma commands the ship across the galaxy in search of new contenders, abducting them from their planet and forcing them to fight for the entertainment of the public. The ship is equipped with different rooms, the main one being the central coliseum and its secondary arenas. It also has rooms where the prisoners reside and eat, and the command center where Slix Vigma, and his sentry robots manage the situation of the ship.
Slix Vigma would kidnap people from their home planets and teleport them onto his ship, where they would be forced to fight in gladiator-like battles for the entertainment of the inhabitants of each Galaxy the Megacruiser went to. To keep its prisoners in line, they were outfitted with electric badges that shocked them if there was any hint of rebellion. The ship is incredibly large and capable of carrying thousands of people, including spectators and fighters.
At the conclusion of Grudge Match, Ben left Kevin on the ship while he escaped. In Back with a Vengeance, it is revealed that Kevin took control of the ship and used it for his own purposes. He located Vilgax with it, and, after a brief skirmish, the two villains made a temporary alliance against Ben and used the ship to return to Earth. It is unknown what happened to it after their defeat.
