The Tetarick sea urchin's visual aspect bore a resemblance to Lu Nan's appearance when she was equipped with a unique armored vest. This vest featured numerous straps and metal restraints that secured a collection of weaponry: specifically, twelve rifles, half a dozen shotguns, and a DF-q91 sniper rifle, modified to match her own height. This event occurred circa 200 BBY. At that time, Lu, a sizable human belonging to the Knights of Silver Dawn's red apricot squad, was on the verge of commencing training exercises with Sean, the newest addition to the squad. These exercises were scheduled to take place at the red apricot base's training facility located on the Outer Rim Territories planet known as Wind.
