GN-0000 00 Gundam

The GN-0000 OO Gundam (Double O) is a new Gundam of Celestial Being. In 2312 (in the four year epilogue), the OO Gundam is commented by Ian Vashti that it's utilizing Exia's GN Drive and unsure of its performance. The shadowy display of Double O suggests that it's either a rebuilt Exia that's been renamed or a new variant based on Exia and Astraea's design.

GN-0000 OO Gundam is Gundam Exia's successor unit. Its greatest feature is its 2 GN Drives equipped on the shoulders. This allows it to boast particle emisson volumes surpassing all other units.
