He is the most calm of the three and acts as the leader of them. Unlike Stella Loussier and Auel Neider, he has no known block word.
Together with his comrades he sneaks into the PLANT colony Armory One, where he steals one of the three new Gundam-type mobile suits, the ZGMF-X24S Chaos. After that he is involved in two other battles in space (the first in the debris belt, the second on the remnants of the destroyed PLANT colony Junius 7) and after the start of the Second Bloody Valentine War, Sting and the rest of the Phantom Pain go to Earth. There they are again involved in several battles against the ZAFT ship Minerva, however with no great success. During this time Sting often fights against Athrun Zala in the ZGMF-X23S Saviour. Sting and his two comrades later investigate the ZAFT-controlled city Diokia, where the three for the first time meet Shinn Asuka and Athrun Zala, however none of them knew who the other is. During the Battle of Crete the Chaos is damaged by Kira Yamato’s ZGMF-X10A Freedom however it is quickly repaired to accompany the GFAS-X1 Destroy piloted by Stella, which destroys several citys in Europe. When the battle reaches Berlin Sting fights against three MVF-M11C Murasame units from the Archangel and is defeated when the Chaos is cut in half. Despite the Chaos being destroyed, Sting somehow managed to survive and was transferred to the Earth Alliance stronghold Heaven's Base in Iceland. There he became the pilot of one of five GFAS-X1 Destroy units and was sent out to defend Heaven's Base when ZAFT's Operation Ragnarok began. He is eventually killed by Shinn Asuka and his ZGMF-X42S Destiny when Shinn impales Sting's cockpit with his Arondight anti-ship sword.
