Malevolent
Malevolent was an EF76 Nebulon-B escort frigate that saw service with the Imperial Navy during the Galactic Civil War. During Imperial Fleet Operation: Clean Sweep, the vessel challenged the Rebel Alliance frigate Endeavor to a ship-to-ship duel which included both warships' contingents of starfighters.
Behind the scenes
While the occurrence of the space battle depicted in this mission, as well as the participants, was C-canon within the Legends continuity, the outcome depends on the actions of the player and is therefore indeterminate. For lack of other canonical information, it should be assumed that the battle had no lasting effect (such as the destruction of either starship).
