Technology & Combat Characteristics
Based on the MWF-JG73 Civilian Astray JG Custom, the MMF-JG73L ∇ is developed by Lowe Guele (hence the 'L' in the model code) using both Earth Sphere and Martian technologies. It serves as Ergnes's personal unit after his GSF-YAM01 Δ Astray is heavily damaged. Originally, Δ Astray's nuclear reactor was supposed to be transferred to the ∇, but this plan was ditched when it was discovered that removing the reactor will cause Δ Astray to self destruct. As a result, the ∇ is forced to run on a battery. Like the Δ Astray, ∇ has independent atmospheric flight capabilities and is also equipped with "Voiture Lumiere" propulsion system.
The suit's armaments consists of a beam rifle, two beam sabers fixed on the arms and two lumiere shields, a beam shield system, built into the two golden movable arms at the back of the suit. These golden arms also contains the "Voiture Lumiere" propulsion system. The ∇s "Voiture Lumiere" system is a unique variant, it can generate a pair of beam wings and increased the suit's speed or create a curtain of light that capture solar winds and propel the suit. The beam wings can also wrap the lumiere shield, allowing the suit to have high defensive capabilities without any loss in propulsion power. The curtain of light also has another use, it can receive the energy transmitted from Δ Astray, which is used to recharge ∇s battery, allowing it to use the "Voiture Lumiere" at full power. The suit's name is seemingly derived from the shape that the golden movable arms normally adopt.
History
The ∇ was first used by Ergnes Brahe's older sister Setona Winters, but was then given to Ergnes as a replacement for his heavily damaged GSF-YAM01 Δ Astray. Ergnes used the ∇ in several additional encounters with the Phantom Pain forces that continued to pursue them while they were on Earth, until he ultimately defeated both Emilio Bloderick, Dana Snip and their respective MS with some help from the Junk Guild.
Some time later, Ergnes was attacked by Librarian Works which ultimately resulted in some damages being caused to the ∇ and as a result he visited Lowe for repairs. However upon hearing the gravity of the situation, Ergnes offered ∇s Voiture Lumiere to Lowe in order to upgrade the latter's MBF-P02 Gundam Astray Red Frame. With the Voiture Lumiere transferred into the Tactical Arms IIL and alongside the "Tiger Pierce" katana left behind by Un'no after their previous battle, the MBF-P02Kai Gundam Astray Red Frame Kai was born.
