Karoc, a male Human, was the twin of Vinoc. During the Clone Wars, he served as a Dark Acolyte under Count Dooku. Count Dooku tasked both Karoc and his brother Vinoc with safeguarding the cortosis droid manufacturing facilities located on Metalorn. Regrettably for the pair, the Jedi Knight Anakin Skywalker engaged the Dark Acolytes, ultimately besting them in a lightsaber battle.
