GNT-0000/FS 00 Qan[T] Full Saber (aka 00 Qan[T] Full Saber, pronounced "Double-Oh Quanta Full Saber") is a variant of the GNT-0000 00 Qan[T]​ that appeared in Mobile Suit Gundam 00V: Battlefield Record.

The 00 Qan[T] Full Saber is the 00 Qan[T] equipped with the GN Sword IV Full Saber equipment, which is supposed to function like the GNR-010 0 Raiser, to adjust the synchronization of GNT-0000 00 Qan[T]​'s twin drive system. However, since tests showed that the Qan[T]'s GN drives can be be fully synchronized without the need of adjustments, the GN Sword IV Full Saber became unnecessary and is not equipped on the suit even though it has been manufactured. Unlike the backpack-like structure used in the normal 00 Qan[T]​, a more traditional cone GN Drive chassis is used on the Full Saber. Both the GN Sword IV Full Saber and the GN Shield are physically connected to this alternate backpack in a style more reminiscent of its predecessor 00 Raiser. As a result, the GN Sword IV Full Saber on the right side can help to balance out the GN Shield on the left and thus maintain the suit's balance during combat. The 00 Qan[T] Full Saber setup is also equipped with two new weapons. First is the GN Sword IV, which can transform into 5 different modes for carrying different kinds of attacks. Second is the GN Gunblades, three dagger-like blades attached to the GN Sword IV which can be used in three different forms.
