The GNX-Y901TW Susanowo (aka Susanowo) is an upgraded version of the GNX-U02X Masurao that appears in season two of Mobile Suit Gundam 00, piloted by Mr. Bushido

A upgraded variant of the GNX-U02X Masurao, which was redeveloped with improved and additional offensive systems, the Susanowo is a true match in close combat for the GN-0000+GNR-010 00 Raiser. It possesses incredible speed and strength, but lacks any notable durability. The red components featured on the Masurao have been recolored to white, making the Susanowo resemble the SVMS-01O Over Flag even moreso than the Masurao. Weapons-wise, the Masurao's GN Beam Katanas have been upgraded into a pair of solid powered sabers resembling katanas, which can be combined into a staff-like weapon.[2] In addition, its abdominal cavity mounts a chargeable GN Cannon, known as the Tri-Punisher. Its Trans-Am System has also been greatly improved compared to that of the Masurao, though the exact nature of such upgrades remains unclear. Beneath its armored head is the head of an Over Flag, and it was specifically taken from the late Daryl Dodge's Over Flag. The Susanowo's antennas and shoulders are similar to the Masurao's, save for the extension of the shoulder spikes and small spikes on the antennas
