Taking some inspiration from KiraZala 16, here I go
GNT-0000/TS- 00 Qan[T] Twin Saber
GN Sword IV Full Saber
GN Buster Sword Kai (basically the GN Buster Sword's blade part with a green edge)
GN Long Gunblade (GN Sword IIs with a green edge)
GN Short Gunblade (stored on knees)
GN Shield III
Before the GN Sword V and the GN Sword Bits were completed, Celestial Being decided to upgrade its old weaponry in case of a fight against the ESF. To that end, they took the incomplete 00 Qan[T] and gave it modified versions of the weapons used by the 00 Gundam.
