Geonosion Ultra-class Star Destructors were built by Geonosians under the supervision of Boba Fett during his take over of the galaxy. They had two hundred Ultra-Lasers that, when fired simultaneously, could destroy an entire planet. During the Battle of Coruscant of the galaxy wars, the Star Destructor split Coruscant. The only one that could get to the control room without being shot at was Yoda.
