Technology & Combat Characteristics

Before Veda settled on the use of humans as Gundam Meisters, there was a competing plan where the meisters are all Innovades. As such, mobile suits specifically for Innovades were also designed and developed in the spaceship, Celestial Being, independent from the Gundams used by human meisters. Unlike the human use Gundams that have their own specializations, Innovade use machines were designed with the concept of having several support-use units operating alongside versatile Gundam-type units. Incorporating weapon technology from the GN-005 Gundam Virtue, the GN Cannon specialized in long-range attacks, providing rear fire support for the CB-001 1 Gundam during battle.

The GN Drive of the GN Cannon is installed in its back, while its armament consisted of four GN Long Cannons mounted on the torso, and eight GN Missile launchers located in both shoulder armor as well as both front skirt armor. To allow the mobile suit to fire its cannons continuously and to meet their huge GN Particle consumption, large GN Condensers are fitted on the arms, and the large back armor on the rear waist doubled as particle storage tanks. Years later, following the defeat of Celestial Being in 2308 AD, the Innovators used the GN Cannon's data for their own purposes. Most notably, the leader of the group, Ribbons Almark, combined the mobile suit's data with that of the 1 Gundam to create the CB-0000G/C/T Reborns Gundam Origin, which was then improved into the CB-0000G/C Reborns Gundam. There are also indications that the Innovators leaked the mobile suit's data, as the GNX-607T/BW GN-XII Cannon's head sensor unit shares similar components with the GN Cannon's.

History

To sabotage the recruitment of humans for the role of Gundam Meisters, Beside Pain mortally wounded Grave Violento via mind controlling Hixar Fermi. He was aware that Gundam Meister 874 would quickly detect his actions and would move to eliminate him, so he shipped his mobile suits over in advance. He then deployed two CBY-077 GN Cannons from the same hangar that 874's GNY-0042-874 Gundam Artemie had launched from moments ago, and they were powered by GN Drives transferred from the 3rd generation Gundams.

The two GN Cannons took the initiative and fired at Artemie using their GN Long Cannons. They then maintained their distance from the Artemie as they continued their attacks. Both units were shut down when 874 activated Artemie's Trial System, but they reactivated when 874's use of the Trial System was overridden by Tieria Erde, who had activated the same system on his GN-004 Gundam Nadleeh. Beside Pain then revealed himself to 874, and uncloaked his CB-001 1 Gundam.

Beam shots from the two GN Cannons and the 1 Gundam repeatedly striked the Artemie, damaging it bit by bit. However, the fatal shot from 1 Gundam was blocked by the GN-XXX + GNR-000 Sefer Rasiel, piloted by a dying Grave. Beside Pain then engaged Grave in a one-on-one duel, and the two GN Cannons did not interfere. When the 1 Gundam was defeated, Beside Pain attempted to transfer his personal data to one of the two Innovades controlling the GN Cannons, who were also under his control. However, he was killed by Grave before his data was fully transmitted. The two GN Cannons remained silent and were presumably recovered by 874's comrades.

Beside Pain reappeared in 2312 AD. He revealed that the one killed in 2302 AD was a clone, and he was actually piloting one of the two GN Cannons and observing the battle.
