Decimator
The Decimator is a fictional weapon mentioned in the Star Wars Expanded Universe.
The Decimator is a massive mechanized unit capable of destroying land, air, and sea units. Its main offensive weaponary is a small globe, similar to a lightning globe. The globe charges up power and unleashes a tight beam, not unlike the Death Star's superlaser, and destroys its target. It also seems that this beam can be used to attack multiple opponents.
The Decimator experiment was conducted on Eredenn Prime in the Erediss system. The General of the Confederacy of Independent Systems, Sev'rance Tann captured it and continued onto Alaris Prime, a Wookiee colony, where they were manufacturing the Decimator. Using a captured Data Droid, Sev'rance Tann managed to take control of the Decimators. When she reported in to Count Dooku, he ordered her to the planet of Sarapin, which supplied large amounts of power to Coruscant. With the newly-acquired Decimators, Tann had no trouble taking over the planet and even killed Jedi Commander Jor Drakas. Echuu Shen-Jon later responded with a strike team, but the General was long gone.
Count Dooku had ordered Sev'rance Tann to set up Decimator foundries on the remote world of Krant. Echuu was able to track her here using information extracted by Confederacy officer Zian Finnis. Echuu led an invasion of decimator facilities on Krant as well as a Trade Federation mining outpost on Krant's moon, Aereen. The campaign on Aereen led to the death of the wealthy Trade Federation businessman Plure Barron. As Barron died, he told Echuu that he was too late and that the Decimators had already been prepared for shimpment offworld. Echuu swiftly landed a strike force on Krant. Aided by some stranded Wookies, Echuu stormed the Decimator facilities and eliminated all of the Decimator machines that the Confederacy had built, along with their factories. Echuu was confident that he had destroyed all the decimators the Confederacy had built, but it is not known whether all the Decimators were destroyed, or if some Decimator devices survived the Clone Wars.
