The System-Turn A 99 (WD-M 01) Turn A Gundam (also known as "Turn A") was first discovered in CC 2345 when the Moonrace's Dianna Counter army arrived on Earth and attacked the city of Nocis; at that time the city was holding a Coming of Age ceremony for Loran Cehack and Sochie Heim where they danced and offered prayers in front of the "White Doll" statue. When the Moonrace forces attacked the "White Doll" statue crumbled revealing the Turn A. When Loran and Sochie took shelter inside the cockpit, it activated and automatically fired at the Moonrace forces (who were unaware of any mobile suits on Earth). After several battles with the Moonrace armies, the Turn A became the symbol and main military might in the struggle to resist the Moonrace's attempts at colonizing Earth. The Turn A's main propulsion was provided by an I-field Beam Drive System, which left the suit completely hollow and allowed it to be filled with extra armaments and rocket thrusters. Standard armament consisted of two beam sabers and a beam rifle. The Turn A was even equipped with an I-Field barrier protecting it from all sorts of attack including nuclear weapons. It's nanomachines onboard are capable of an attack named "Moonlight Butterfly" (named after the effects of the attack when active), however, 3 requirements have to be met in order to unleash this attack, the nanomachines, the energy and the program to activate the attack. The two turn series MS both contained only 2 of the requirements, which rendering them unable to unleash that attack alone. Both have sufficient energy to start the attack but Turn A only have the nanomachines and Turn X only have the program to activate the attack.
