Wing Gundam is one of the five Gundams sent to earth during Operation Meteor in the series Gundam Wing. It was created by Doctor J and is piloted by Heero Yuy.
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. It was code-named "Gundam 01" by the OZ forces, and was also capable of transforming into a fighter-like "bird mode" for added mobility and atmospheric flight.
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 much of the mobile suit's armor fairly intact). These factors made the Wing Gundam extremely tough to stop when it was launched to Earth to fight OZ. When it was first deployed in Operation Meteor, it was intercepted by an OZ reconnaissance team headed by Zechs Merquise. In the ensuing fight, the Wing Gundam destroyed twoOZ-07AMS Aries with a single shot, but was pinned by Zechs's Leo and fell into the ocean. It was recovered from the ocean bottom shortly thereafter by Duo Maxwell, and fought in many more battles until it's primary pilot, Heero Yuy, self-detonated it in Siberia. Zechs Merquise eventually rebuilt it at the OZ base in Antarctica, and it continued to fight again until Heero Yuy left it on the ocean bottom again while he went into space, due to it's insufficient combat capability in space. This time Sally Po recovers it from the ocean floor and sends it to the Sanc Kingdom, where once Heero returns, he uses it to defend the Sanc Kingdom until he abandons it at Luxembourg for the more powerful OZ-13MS (Gundam Epyon). OZ later recovers it, and repairs and upgrades it with boosters for space travel. It is at this point the Wing Gundam sees it's last bit of service when Lady Une uses it to save Treize Khushrenada from Libra's main cannon. Heavily damaged, Lady Une abandons it and it is unknown if it was ever completely destroyed.
