Griknaz, a Gamorrean of the male persuasion, held the position of Refinery Security Force Captain on Hutta under the employment of Vobbara Yusinduu. Unusually, he possessed the capability of speaking Basic with exceptional clarity and eloquence, a trait that distinguished him from others. Formerly, he had achieved renown as an Arena Champion. While directing his security personnel to quell a rebellion of slaves against Yusinduu, Griknaz encountered both the Alliance Commander and Sa'har Kateen. In the presence of his Hutt superior, Griknaz engaged the pair in combat, swiftly discerning that they operated independently. Despite his efforts, he was defeated and injured. The pair then attempted to extract information from him regarding the whereabouts of a shuttle owned by the Hidden Chain. However, before Griknaz could utter a response, one of Yusinduu's subordinates executed him, acting on the Hutt's command.
