New Union's Armored Gestalt. officially named the "Desda" for the head engineer of the mech. It's more commonly known as the "Number 6" or "Six" as a play of the acronyms and model number.
The basic model is the NU/M-06. A very versatile and modifiable AG, it was designed to be a general model, capable of working efficiently in virtually all terrain and environments. Its origin is based in the enemy's own AG.
The NU/M-06L, the 6 Cannon, is a fire support variant of the basic Number 6. There have been few changes to the AG but the back unit was replaced with a cannon toting version. The cannon has its own sensory unit and is capable of long-range viewing.
The NU/M-06A, the Aqua Six also known as the "Fish-eye". An aquatic variant of the 6, it was proposed as an attempt to improve aquatic performance of the basic 6. Though the basic model was designed to handle well in all environments its performance in deep water was less than optimal due to the inefficiency of rockets. To fix this the Aqua Six was given several hydrojet attachments, giving it higher mobility in water. This proved useful in combating even the enemy's aquatic AGs that were designed for aquatic combat from scratch. The sensor was also changed to a compound, mono-lens "fish eye", designed for the low light and translucency of deep water. Several torpedo launchers were also attached as side weapons, raising the combat efficiency.
The NU/M-06C, the 6 Commando. It is a heavily modified version of the original 6. It's almost a new design given the modifications to improve almost every aspect of the AG. Its performance almost exceeds the high power prototype of the entire series.
The NU/M-06S, the 6 Shooter, is a modified 6 Commando. The modifications were minor: a change to the shoulders to provide extra thrusters for mobility and a new visor with a long-range camera. It is equipped with a high output beam rifle, capable of equipping a long-range barrel.
The NU/M-00, the only suit commonly called the "Zero". The Zero is the basis for all later New Union AG designs and while it shares appearances with the basic "Six" the internals, armor material, and head are radically different. Its performance is much higher than the "Six" and is the equivalent of the "Six Commando", though the armor is superior on the Zero.
