When the five scientists who designed the XXXG-00W0 Wing Gundam Zero in AC 180 went their separate ways, each of them took copies of the plans for their original Gundam design. Master O, who went into hiding in the L5 colonies, then went on to design and build his own Gundam based on their original plans. With the support and blessing of the powerful Long clan, Master O built the XXXG-01S Shenlong Gundam in anticipation of Operation Meteor. However, the Shenlong's intended pilot, Mei Lan Long, was killed during an encounter with Earth Alliance and OZ forces in AC 194. Her betrothed, Chang Wufei, took her place as the Shenlong's pilot. Not wanting to use the Gundam as a tool for genocide, Wufei refused to take part in Operation Meteor's planned colony drop, instead taking his Gundam (named "Nataku" after Mei Lan's nickname in her memory) to Earth to fight OZ's forces directly in a bid for revenge.

Constructed with nearly-indestructible gundanium alloy, "Gundam 05" (as it was code-named by OZ's forces) was armed with the standard head vulcan guns, but being a mobile suit for close combat, it carried a beam glaive as a primary weapon. "Shen long" is Chinese for "god dragon," and the Shenlong Gundam lived up to its name, as its other main weapon was its "dragon fang," composed of the flexibly long right arm and a "dragon head" claw. The dragon fang arm worked effectively both as a grappling and a striking weapon, and it also mounted a pair of flamethrowers, giving the dragon a little more "bite." The Shenlong also carried a "shenlong shield," which doubled as a good throwing weapon. With the same deadly ferocity as his own martial arts skills, Wufei would use his Nataku as his sword of justice against OZ.
