The ASW-G-08 Gundam Barbatos Lupus Rex (ガンダムバルバトスルプスレクス?) is the main mobile suit featured in the latter half of the second season of Mobile Suit Gundam IRON-BLOODED ORPHANS. It is piloted by Mikazuki Augus.

Technology & Combat Characteristics[]

The 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.[1] Data sampling of Barbatos Lupus' fight with Hashmal was also conducted during the overhaul.[2] 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.[1] Movement of the frame's joints were also delicately tuned to match the pilot's actual sensations.[1] The suit's cockpit hatch was changed from its predecessors' top opening method to a front opening style in consideration of Mikazuki's worsened disabilities.[3]

To more intuitively reflect Mikazuki's fighting style, the suit's arms were enlarged and elongated like a beast, and various weapons are fitted on the body.[1][4][5] The arms' frame structure was also upgraded and reinforced.[1] The tail parts of the Hashmal was transplanted to the suit's back, and through the Alaya-Vijnana System, Mikazuki controls this tail blade as if it was a limb.[1] Overall, the Gundam Barbatos Lupus Rex is customized for close combat, and its silhouette gives it a more ferocious look than its predecessors.[1][4] 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."[1]


  • Ultra Large Mace
Developed for Gundam Barbatos Lupus Rex by Teiwaz's MS workshop, besides fitting Mikazuki's combat style, this heavy weapon also takes into view combat against battleships.[1][3] The telescopic handle helps to close the gap with enemy unit.[1] When not in use, it can be mounted on the rear waist horizontally.[1]
  • Pile Bunker
The tip of the mace and the bottom of its handle are equipped with a pile bunker each.[1]
  • Tail Blade
The Hashmal's tail parts were transplanted onto Barbatos Lupus Rex's back, and combined with a blade made of rare metals for better close combat performance.[3][5] The resulting tail blade can retract or extend to strike opponents as directed by Mikazuki through the Alaya-Vijnana System, and is useful for one against many or other unfavorable combat situations.[2][5]
  • Rex Nail
Due to the Rex Nails mounted on the fingers, the arms of the Barbatos Lupus Rex can function as powerful weapons that can pierce opponent machines.[1] Like the Tail Blade, the Rex Nails and the suit's toes are made of rare metals.[6][2]
  • 200mm Gun
Each forearm contains a built-in 200mm gun.[1] This weapon is a further development of the Gundam Barbatos Lupus' firearms.[2]
  • Heel Bunker
Barbatos Lupus Rex is equipped with pile bunkers on both heels.[5]
  • GR-H01 9.8m Battle Axe
A close combat weapon used by the Graze that the Barbatos Lupus Rex obtained temporarily during its last battle.[7]
  • Anti-Ship Lance Mace
An optional lance-shaped mace designed for anti-ship combat, it has a telescopic handle.[8]

Special Equipment & Features[]

  • Sub-Arms
A sub-arm is stored within each forearm.[1] When deployed, the black part on the back of the forearm will flip open, and the sub-arm will unfold into its full length.[1]


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 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.

Notes & Trivia[]

  • The Barbatos Lupus Rex's appearance, with its claws and extendable tail blade, bears a resemblance to a demon, which is fitting as it is named after the demon 'Barbatos'.
    • In Latin, Lupus means "wolf", and Rex means "king", while Barbatos is derived from the latin "barbatus" which means bearded. So "Barbatos Lupus Rex" literally means "Bearded King of Wolves" in latin.
  • The unused concept design for the final battle, which features the left shoulder armor from a Reginlaze and Barbatos 1st Form's left arm, can be replicated in Gunpla form using parts from the HGIBA MS Option Set 9.
