The GF13-017NJII God Gundam (aka G Gundam, Burning Gundam in the English dub) is the titular Mobile Fighter of Mobile Fighter G Gundam. It was the second Mobile Fighter used by Neo Japan in the 13th Gundam Fight, and is piloted by Domon Kasshu.

The successor of the GF13-017NJ Shining Gundam, the God Gundam was developed by Dr. Mikamura almost single-handedly and customized for Domon Kasshu. Even in Normal Mode, its power surpassed that of the Shining Gundam's Super Mode. In addition, it could achieve an even more powerful state called Hyper Mode.

Its chest was equipped with the Energy Multiplier System, a unique system that allows energy to be refined in a similar manner to Qi. When piloted by Domon, the King of Heart emblem would appear upon it. It was part of a larger system called the Artificial Aura Generator. The six Core Lander wings on its back (which were named "Dream", "Illusion", "Bubble", "Shadow", "Dew", and "Lightning", after a passage from the Diamond Sutra) and the two short antennas on its head serve as magnetic field generating devices, while the two long antennas function as intelligence-gathering devices. When Hyper Mode is activated, the Energy Multiplier opens up, the six wings deploy, and a ring of light appears on the God Gundam's back, coating it in a magnetic field that improves its mobility through a full-body magnet coating.

The God Gundam was armed with a pair of head-mounted vulcan guns, a pair of 3-barrel machine cannons mounted on the upper chest, and a pair of beam swords known as "God Slash". In Hyper Mode, it was capable of using a finisher move known as Bakunetsu God Finger, a refined and more powerful version of Shining Finger. Its forearms were covered in armor known as "G Knuckles" or "God Finger Protectors", which were based on the finishing move of Neo Albania's Gundam Fighter during the 12th Gundam Fight.
