The Le Cygne was a Gundam-type mobile suit developed and constructed by Anaheim Electronics (AE) before the start of the Gryps Conflict. A test unit specifically designed for use by AEUG pilot Asuna Elmarit, an A-rank newtype, it is considered a reflection of Asuna's test data. The Le Cygne's shared the frame of the MSA-003 Nemo and its concept was unusually traditional for its time, whereas the Gryps-era mobile weapons saw rapid development in TMS (Transformable Mobile Suit) technology. This unit featured a sleek design and also drew inspiration from the MSN-00100 Hyaku Shiki, as it was designed to be a light, fast and highly agile unit. The machine's overall frame was greatly simplified, with emphasis on mobility and ease of maneuverability, and therefore lightly armored. The backpack was a miniaturized four-thruster type that enabled quick and precise movement. The Le Cygne had distinctive shoulder parts that were actually all-purpose compartment bays which protruded forward. The slide rails inside the hatches of these bays could store a hidden gatling gun and also stored the unit's main beam sabers. These components could easily be removed and replaced for a variety of mission roles.
It was determined that Asuna was the only pilot who had the ability to maximize Newtype response feedback to the Le Cygne itself. In addition, simulation data that reflected Asuna's past simulator trials in AE's Amman branch had been inputted into the control system and were adjusted to extract the best possible performance from the Le Cygne.
