Also known as: オーライザー, 0ライザー
Celestial Being support craft. Unites with the 00 Gundam, forming the 00 Raiser and stabilizing the twin GN Drive performance to create a more powerful Trans-Am and using it with complete safety (unlike the base 00 if it uses Trans-Am by itself, which will cause the GN Drives to overload, and risk having their total destruction as a worst-case scenario).
As an individual unit, the 0 Raiser is equipped with GN Beam Machine Guns, GN Micro Missiles, and GN Vulcans.
Piloted by Saji Crossroad.
