An upgraded and repaired version of the Gundam Aerial. First seen on Episode 11 of Gundam Suisei no Majo's first season/cour, it then made its proper debut in Episode 12. Suletta Mercury remains as its pilot.
Aerial's upgrade to the Rebuild is reminiscent of Gundam GP-01 Full Vernian Zephyranthes from Gundam 0083, such as having additional thrusters, armor, and the upgrade and repairs being done at the same time after its initial form got heavily damaged in a previous combat. It also has a mouthpiece with single vent, a rarely used Gundam face design that is only seen in few Gundams such as Bolt Gundam from Mobile Fighter G Gundam, Raigo Gundam from Gundam SEED Frame Astrays, and Gundam G-First from Gundam U.C. 0096: Last Sun.
In Season 2, it is revealed that the Gundam Aerial/Rebuild is either the current body or contains the consciousness of Ericht Samaya.
Its real life mechanical designer is JNT, who is also the designer of the base Aerial and Gundam Lfrith.
