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. Doctor J, who went into hiding in the L1 colonies, then went on to design and build his own Gundam based on their original plans. Of the five Gundams that would be built, Doctor J's XXXG-01W Wing Gundam most closely resembled the original Wing Zero in form and armament. Packing beam sabers, vulcan guns and machine cannons, its weaponry was topped off by its powerful "buster rifle," capable of firing an energy beam wide enough to destroy several enemy mobile suits in a single shot. The buster rifle's only drawback was that it was only good for three shots before it needed to be recharged. "Gundam 01," as it was code-named by the OZ forces, was also capable of transforming into a fighter-like "bird mode" for added mobility and atmospheric flight.

Of course, the Wing Gundam could take almost as much punishment as it dished out. Built of nearly-indestructible gundanium alloy, the Wing Gundam could withstand everything from heavy weapons fire to direct missile hits (even its own self-destruct system left most of the mobile suit fairly intact). These factors made the Wing Gundam an extremely tough monster to stop when it was launched to Earth to fight OZ during Operation Meteor in AC 195. And in the hands of its suicidal pilot, Heero Yuy, it was truly a force to be feared.
