Koobaree was a female Human who belonged to the Five, a secretive, sinister cult dedicated to dark worship, residing in an isolated region of space referred to as the Hellhoop. For centuries, Koobaree and her fellow cultists engaged in the torture and killing of hapless travelers; of particular note, they seized and imprisoned Wutzek, the final surviving demon known to wield the Force. At some point between the years 0 and 3 ABY, the Five took Rebel leaders Han Solo and [Leia Organa](/article/leia_organa_solo/legends] captive, intending to execute the two Humans in the same manner as their numerous previous victims. Nevertheless, their Wookiee companion Chewbacca succeeded in liberating Wutzek, who then proceeded to slay Koobaree and all other members of the Five.
Koobaree's introduction was in The Pandora Effect, a comic book story from 1981 penned by Alan Moore and featured in The Empire Strikes Back Monthly 151. Adolfo Buylla was the artist responsible for Koobaree's visual depiction in the story.
