The MSN-03 Jagd Doga (ヤクト·ドーガ) is a Newtype-use mobile suit introduced in Mobile Suit Gundam: Char's Counterattack. It is piloted by Gyunei Guss and Quess Paraya. The Sleeve-customized version is piloted by Zechst Ade as seen on Mobile Suit Gundam Unicorn: The Noble Shroud manga.

Based on the frame of the mass-produced AMS-119 Geara Doga, the MSN-03 Jagd Doga was a special suit designed to be used by Neo Zeon's Newtype pilots. Developed using data from the evaluation tests of the AMS-120X Geara Doga Psycommu System Test Type and the AMS-119N Röte Doga, it has a Psycho-Frame cockpit for controlling the six funnels stored on its shoulder-mounted funnel pod shields. Unlike previous mobile suits that utilize funnel weapons, the Jagd Doga cannot recharge its funnels. Other weapons of the suit include a beam saber with attached heat knife for close combat, two triple missile launchers behind the funnel pod shields, and a beam assault rifle for Gyunei's unit, while Quess' unit carried a mega Gatling beam gun.

The Jagd Doga's sensors, thrusters, and nuclear reactor have also been significantly improved compared to those on Geara Doga. As a result, it has greater speed and mobility, and more power for its weapons and other systems. In terms of performance, the Jagd Doga was the second most powerful mobile suit in the Newborn Neo Zeon's arsenal, second only to the MSN-04 Sazabi.

In U.C. 0096, Quess' Jagd Doga was repaired and modified by the Sleeves for their own use. A Geara Doga's right arm served as a replacement for the original that was lost during the Second Neo Zeon War. However, it also lost the right arm's funnel pod shield because of this. Other modifications include a Geara Doga's backpack replacing its original one, two funnels for its remaining funnel pod shield, and it was repainted yellow and dark gray and given the personal markings of units used by the Sleeves.
