A mobile suit made by Anaheim Electronics and piloted by the main character, Jona Basta. It was developed as a prototype for the RX-93 Nu Gundam, and many portions of its body are made from identical parts. Because it was intended mainly as a testbed for data collection, there are many areas that have not been equipped with armor, leaving the frame structure exposed. Created as a testbed, the base machine is armed only with head vulcans, and during Operation Phoenix Hunt it uses a variety of interchangeable armament provided by Luio & Co.
The golden third unit of the Unicorn Gundam, created using construction data from the white first unit and the black second unit, and based on a full psycho-frame that was delivered early for testing purposes. It went missing in U.C. 0095 after an incident in which it ran wild.
