Griknaz was a Gamorrean male. A former Arena Champion, with the unique ability to speak Basic clearly and fluently, he later acted as the Captain of the members serving Vobbara Yusinduu on Hutta. Griknaz was leading his forces against a slave uprising against Yusinduu when he was confronted by the Alliance Commander and Sa'har Kateen. Under the watch of his Hutt employer, Griknaz duelled the two, and quickly realized they were independent agents. He was ultimately overwhelmed and left wounded, to which the two interrogated him for the location of a shuttle belonging to the Hidden Chain. Before he could say a word, one of Yusinduu's men gunned down the Captain on the Hutt's orders.
