Earth Federation Space Force (EFSF) officers stationed at the asteroid fortress Pezun rebel against the Federation leadership, which has allied with the Anti-Earth Union Group (AEUG). They self-claim themselves "New Desides" and swear to uphold the Titans' ideology of Earthnoid supremacy. The EFSF assembles Task Force Alpha, a force of EFSF, AEUG, and Karaba veterans equipped with the most advanced mobile suits, and sends them to Pezun to suppress the rebellion before it gets out of hand. The most powerful of them, the "MSA-0011 S Gundam", is equipped with an artificial intelligence named ALICE (Advanced Logistic and Inconsequence Cognizing Equipment).
