-Gundam Barbatos: About 300 years ago, the Calamity War drove by humanity itself caused the civilization decline. Barbatos is an ancient MS produced in that era. Even with that era's technology mounting 2 Ahab Reactors and making them operate in parallel high output was extremely difficult, so 72 machines using a Gundam Frame fuselage were rolled out. All of those 72 machines have an individual name registered to them, Barbatos' Gundam prefix is a rare name for a MS to bear. The burden on the pilot is high due to the high output and high maneuverability, however it's mitigated by the implementation of Inertial Control due to the use of Ahab Particles generated from the reactor when a phase transition occurs inside its vacuum device. The cockpit structure is positioned in front of the reactor to take advantage of this. Among the same frame machines, Barbatos has been adjusted for an emphasis on versatility, it has the potential to adapt to every circumstance by performing exchanges of all sorts of equipment.
-Mikazuki Augus: boarded the Barbatos when Gjallarhorn attacked the CGS HQ facility then became its pilot. He has received the Alaya-Vijnana(storehouse consciousness concept from Buddhism) System surgical treatment 3 times and still returned alive. This system grants excellent spatial awareness and since ancient MS require rapport from an Organic Device Sytem, compatibility with Barbatos is very good. Inspired by Gjallarhorn attack, he participates with the mobilized children including Orga Itsuka in starting up Tekkadan. He has never been to school and can't read properly.
