World Devastators
From Ewokpedia
World Devastators, also known as World Smashers, World Sweepers, Planet Smashers, City Destroyers, Planet Eaters, City Devastators, Planet Devastators, or City Eaters, were gigantic death star rip-offs, successors of the Imperial Leviathan, with strong tractor beams attached to them that could wreak havoc on planets. They were designed by Umak Leth and employed by Emperor Palpatine's clones, which his spirit inhabited. The first World Devastator was built out of the Constructicons, a team of Imperial robots that turned into various construction vehicles and broke quite easily.
[edit] Characteristics
Although it is debatable at great, nerdy and boring length if the World Devastators were deadlier than the Death Star, they were undoubtedly more efficient. The Death Star could merely destroy worlds, while the World Devastators could use a targeted world's material resources to make Tie Fighters and shit. Their primary tactic was to land on the surface of a planet. There, its mighty tractor beam projectors would literally tear the planet beneath them apart, thus making them "planet killers". They were similar in function to the Star Forge.
