GNX-Y901TW Susanowo

The Susanowo is an upgraded version of the Masurao. The red components have been changed to white ones, which makes the Susanowo much more greatly resemble an Overflag than before. Rather than the GN Beam Katanas of the Masurao, Susanowo wields a pair of solid state GN Katanas that can be combined into one sword-staff weapon. In addition, its abdominal cavity mounts a particle cannon. Its Trans-Am system has also been upgraded, though the exact nature or improvement of such is unclear.

The name, Susanowo, (スサノオ ?, also romanized as Susano'o, Susa-no-O and Susanoo) is the Shinto god of the sea and storms.

Combat Characteristics
A rather strange instance in that it is a custom of a custom, Susanowo is designed near-exclusively for close combat, having been built specifically to combat thw GN-0000 00 Gundam. It possesses extreme speed and strength, but lacks any kind of durability.

GN Katana
The Susanowo has two solid GN katanas that can be joined together.

GN Cannon
The Susanowo's primary energy weapon is the GN particle cannon, a powerful particle beam weapon concealed within its abdominal cavity. The particle beam forms a large orange beam at the abdomen and the shoulders help charge the particle projectile for firing. It is unknown if the Masurao also mounted this weapon.

Trans-Am System
Refined over the system mounted on the Masurao, the Susanowo is capable of matching even the speed of 00 Raiser while in Trans-Am. As Susanowo lacks powerful enough internal G-dampers to compensate for its speeds in Trans-Am, this mode is very hazardous to the pilot's health.

History
Appearing first at the L5 colony, Mr. Bushido appears and challenges Setsuna to a duel in his new Susanowo, after revealing his identity as Graham Aker. Setsuna agrees, though he remains distracted throughout the middle portion of the duel by the nearby encounter between Louise Halevy and Nena Trinity. As the fighters simultaneously enter Trans-Am, Graham is carried along with Setsuna in a quantum brainwave experience, wherein Setsuna explains that he finally understands the true nature of Aeolia's plan. As the battle continues, Susanowo briefly gains the upper hand by disarming 00 of its GN Sword II, but the Gundam counters with a blade block that snaps Susanowo's katana in half. Setsuna quickly makes short work of Susanowo with his beam sabers, and the unit's helmet shatters to reveal that underneath the samurai armor lay the original GN Flag. Setsuna refuses to finish Graham and leaves with Graham contemplating to commit seppuku. He however doesn't do so and after the defeat of the Innovades is seen meeting Billy Katagiri. What has happened to the Susanowo remains unknown.
