The Malevolence was a Subjugator-class heavy cruiser active during the Clone Wars. It served as the flagship of the Confederate General Grievous. The massive ship was longer than four Venator-class Star Destroyers and sported massive ion cannons, capable of disabling enemy ships, mounted on both sides of its hull. The Malevolence was a Subjugator-class heavy cruiser. 4,845 meters long, it possessed two twin ion cannons. Once fired, the wave from the cannons would expand over greater distances and disable any enemy spacecraft upon impact. After the ion cannon had disabled an enemy warship, approximately 500 turbolasers were mounted on the ship's enormous hull to fire upon the disabled vessel. The vessel's power plant operated by recapturing waste heat and propulsion by-products. The design required a gigantic hull and was required to vent its stored energy on a regular basis, which was adopted to the ion cannons.
