Technology & Combat Characteristics
The ASW-G-08 Gundam Barbatos Lupus fought a fierce battle against the mobile armor Hashmal in the vicinity of Chryse, a city on Mars and was so severely damaged that it was sent to the Saisei's MS workshop for a major upgrade. Data sampling of Barbatos Lupus' fight with Hashmal was also conducted during the overhaul. To match the combat data of Mikazuki Augus, who was increasing his compatibility with the mobile suit through the Alaya-Vijnana System, the machine's response speed was increased to the limit of its theoretical value. The arms' frame structure was also upgraded and reinforced. The tail parts of the Hashmal was transplanted onto the back of the mobile suit, and through the Alaya-Vijnana System, Mikazuki controls this tail blade as if it was a limb. Overall, the Gundam Barbatos Lupus Rex is customized for close combat, and its silhouette gives it a more ferocious look than its predecessors. The word 'Rex' means 'King' in Latin, and this is fateful as Mikazuki is going along with Orga Itsuka, whose aspiration is to be "King of Mars."
History
The ASW-G-08 Gundam Barbatos Lupus Rex made its combat debut during Tekkadan's attack on JPT Trust, a Teiwaz subsidiary headed by Jasley Donomikols. It easily dispatched JPT Trust's mobile suits, and ended the battle by killing Jasley through destroying the bridge of his ship with the Ultra Large Mace.
It was later sent to Earth to assist in McGillis Fareed's coup of Gjallarhorn, and played a role in disabling the mobile suits at the organization's headquarter. It then engaged the ASW-G-XX Gundam Vidar in the headquarter's basement. Initially, Barbatos Lupus Rex had the edge, but they fought on more equal terms when Vidar's Alaya-Vijnana Type E was activated. The fight stopped after ASW-G-01 Gundam Bael's intervention, and Vidar retreated back to space.
During the battle between the Arianrhod Fleet and McGillis's Revolutionary Fleet, which Tekkadan had allied with, the Barbatos Lupus Rex was kept occupied by the unrelenting EB-08jjc Reginlaze Julia as per Rustal Elion's plan. This neutralized the effects the Gundam had on the battle. Later, when Tekkadan came up with a daring plan to charge into the Arianrhod Fleet, the Barbatos Lupus Rex was deployed as the vanguard. It then clashed with the Reginlaze Julia again and severed the latter's left arm. However, it failed to stop the Reginlaze Julia from interfering with the ASW-G-64 Gundam Flauros (Ryusei-Go)'s Dainsleif shot at the enemy flagship, and as a result, the attack missed its mark.
When Tekkadan's Mars headquarter was surrounded by the Arianrhod Fleet, the Barbatos Lupus Rex was deployed alongside the group's remaining mobile suits to buy time for the non-combatants to escape via the secret tunnel underneath the base. The mobile suit was heavily damaged when the Arianrhod Fleet launched an orbital Dainsleif bombardment. Despite this, it continued fighting until its pilot, Mikazuki, passed away from his fatal injuries.
