The Shenlong, the fifth Gundam created for Operation Meteor, was developed by Master O for the Long clan of the L5 colony cluster. The Shenlong's name means "God Dragon" in Chinese, reflecting the heritage of this proud warrior clan. 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.The Shenlong Gundam is designed especially for melee combat, in which capacity it benefits from the martial arts skills of its pilot Chang Wufei, who would use his Nataku as his sword of justice against OZ..

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. Its most devastating armament, though, is the "dragon fang" built into its right arm. The dragon fang arm worked effectively both as a grappling and a striking weapon, and it also mounted a pair of medium-range flamethrowers. The Shenlong also carried a "shenlong shield," which doubled as a good throwing weapon.
