The RX-78-02 Gundam (RX-78-02 ガンダム?) is the titular mobile suit of the Mobile Suit Gundam: The Origin manga. It was piloted by Amuro Ray during the One Year War.

Technology & Combat Characteristics


The RX-78-02 Gundam's primary armaments include a pair of beam sabers, mounted one to each side of its backpack, as well as the same beam rifle used by its predecessor, the RX-78-01 Prototype Gundam. In addition to this, it has a pair of Vulcan guns mounted in its head, a small Gatling gun in a recessed compartment on its right shoulder, and a pair of shoulder magnums on the left shoulder. A pair of machine guns and magazine are mounted in the left forearm.

The RX-78-02's armament is supplemented by a hyper-bazooka, and it is able to exchange its backpack for one that mounts the same armament as the Prototype Gundam, with the left beam saber replaced by a powerful cannon.


U.C. 0078

The project was proposed by Tem Ray in the year U.C. 0078 after he watched the footage of a MS-04 operating in the A Bao A Qu region. He immediately realized that, had the Federation gone ahead with mass-producing the Guncannon, geared toward ship combat at the time, the mobile suits would fare poorly against these Zakus. While the Federation at first believed the RX-77-01 would suffice, Tem's theory was proven true during the Battle of Mare Smythii, in which 4 MS-05 Zakus, alongside the MS-04 Bugu, wiped out the 12 Guncannons of the Iron Cavalry Squadron, and thus illustrated to the Federation the need of a Mobile Suit geared toward for Mobile Suit Combat, leading to the approval of the RX-78 Gundam development Project. Amuro Ray later discovered that his father was not just working on colony construction as he discovered the suit's blueprints and a scaled-down RX-78-02 arm in his father's room [1].

One Year War (U.C. 0079)

Side 7 (September)

On the day Zakus infiltrated the Noa colony, Amuro Ray was at his computer accessing top-secret Federation data. After coming across another security layer, he opened a file containing a diagram of the Gundam's head. He saw the name "RX-78 Gundam", more "weird numbers" and schematics. As Fraw entered his house, Amuro also saw a diagram of a Zaku and how it had a fusion engine within its torso, strengthening his beliefs that his father had more than just colony blueprints [2].
