Sting, along with Auel Neider and Stella Loussier, are the three Extended pilots of the Earth Alliance’s special forces team, called Phantom Pain. 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. 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 Phantom Pain go to Earth. On Earth, he and his comrades engage in several battles with against the ZAFT ship Minerva, but meet with little success. Sting often fights against Athrun Zala in the ZGMF-X23S Saviour.
