Malevolence

Calum completed his Lego star Wars Malevolence ship.

It starred in The Clone Wars, season 1 episodes 2 to 4.

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 dual ion cannons, capable of disabling enemy ships, mounted on both sides of its hull. The ship was first spotted by Republic forces around 21 BBY by Jedi General Ares Nune and Clone Commander Kite, who were on an inspection in the Phu system. Grievous took the opportunity to fire the ion cannons on Nune's fleet, destroying it.
