The fifth unit of the Earth Federation’s Tsentr Project, the Medius Locus was a real robot that served as the testbed for armor made from Lasmunanium alloy, which had the ability to self-repair and evolve. It was not equipped with a Terminus energy engine for fear of its effect on the Lasmunanium. The Medius Locus was also loaded with the advanced artificial intelligence AI1 All-In-1. It was designed to be a well-rounded machine and was armed with a coating sword and a divided rifle.
The Medius Locus was stolen by Eldy Middi and Albero Est. Albero served as the main pilot while Eldy supervised AI1. Albero’s former subordinate Hugo Medio and Eldy’s former student Aqua Centolm gave chase in the Terminus energy-powered Tsentr unit. Albero and Eldy aligned themselves with several factions seeking to conquer Earth in order to let AI1 gain experience. After many encounters with Hugo and Aqua, the Medius Locus eventually acquired the TE engine of the other unit.
The TE Engine greatly powered up the Medius Locus, causing the Lasmunanium to evolve and change the robot’s shape. The Medius’ second form was that of a super robot. Its armaments included eight riot boomerangs, two spiral fangs, and the Terminus blazer. It was able to create a TE Sphere barrier thanks to the TE engine. It also had the ability to create Y??-01 Telgum and Y??-02 Flonnes from Lasmunanium. AI1 continued to gather combat data by fighting many enemies. As the apocalyptic events of the Tuning and the Human Instrumentality Project got underway, the source of Mutron energy, the Star of La Mu, appeared. Eldy has AI1 absorbed the star, which caused the Medius Locus to evolve further.
The third form of the Medius was far different from the previous two. The machine now resembled a giant monster and attacked with brute force. Eldy and Albero had no control over this form; only the berserk AI1 did. AI1’s core unit continued to expand and eventually absorbed the machine.
