Technology & Combat Characteristics
As the ASW-G-08 Gundam Barbatos fought many battles with its pilot Mikazuki Augus, it became too damaged to be repaired by Tekkadan. It was then sent to the MS Workshop in Saisei, the home base of Teiwaz, for an overhaul. Based on Mikazuki's combat data, the mobile suit was reconfigured as a close combat unit, and its reaction speed and mobility were also increased, with adjustments made through the Alaya-Vijnana System to bring the machine's movement closer to its pilot's senses. Furthermore, frame parts in the arm and leg joints were replaced by those reproduced by Teiwaz, helping to resolve the accumulated damages and also improved their movability. Lastly, a pair of waist thrusters capable of instantaneous bursts were added at Mikazuki's request, and they were based on the waist-mounted boosters previously used by the Barbatos 6th form. Although the amount of propellant that could be carried by these waist thrusters left much to be desired, Mikazuki was unbothered.
The mobile suit's armaments were renewed to better fit Mikazuki's close combat fighting style, and handheld firearms were kept to a minimum. Instead, it uses exchangeable firearms attached to the forearms. Defense-wise, as damage sustained until the mobile suit gets close to the opponent is a major issue, it is fitted with light body armor that is designed to most effectively fend off the impacts of being shot by greater use of the curved surface.
History
The Gundam Barbatos Lupus was first deployed during the defense of a half-metal mine run by Kudelia Aina Bernstein's Admoss Company. It aided the other Tekkadan's Mobile Suits, the Shiden and Shiden Custom, in repealing the attack of the Dawn Horizon Corps' Garm Rodis. After forcing the enemies to withdraw, the Barbatos Lupus stopped working due to an impact received from its hard landing earlier. Later it was deployed to fight off the Dawn Horizon Corps in space, destroying multiple Garm Rodis and eventually defeating the Hugo used by the group's leader Sandoval Reuters, leading to his capture by Mikazuki.
During the Arbrau-SAU war, it was deployed alongside the Gundam Gusion Rebake Full City and some Shidens to aid Tekkadan's Earth Branch and protected McGillis during the conflict. During a later battle in the same war, it rescued a shocked and inexperienced Hush Middy from a Geirail Scharfrichter.
The Barbatos Lupus was severely damaged in the battle against the Hashmal, a mobile armor from the Calamity War. It was then sent back to Saisei for an overhaul, and was upgraded into the ASW-G-08 Gundam Barbatos Lupus Rex. Before the damaged Barbatos Lupus was sent to Saisei, a group picture of Tekkadan was taken in front of it. A copy of this photo was seen years later in the house where Atra Mixta and Akatsuki live in.
