Altron Gundam was built from the damaged XXXG-01S Shenlong Gundam, with the five Gundam scientists quietly using the OZ manufacturing facilities on the Moon to upgrade the mobile suit with new equipment and weaponry. Altron was still a close combat unit, but was given more mid-range weaponry.
While Shenlong had only one "Dragon Fang," Altron was equipped with two of them (hence the name, taken from the Chinese "ertou long" or "two-headed dragon") and their reach has been dramatically increased. The original Beam Trident was replaced with a double-ended Twin Beam Trident, and a Twin Beam Cannon mounted on a flexible tail was added to its backpack, giving it additional ranged firepower.
Altron was also reconfigured with greater mobility, and adapted for space combat with more thrusters and a new pair of wing-shaped binders. These binders, together with the Twin Beam Cannon, are known collectively as the "Futier" equipment. Overall, Altron has twice the fire power and combat capabilities of its predecessor. Added with Chang Wufei's martial arts combat skills when piloting, Altron is one of the most formidable mobile suit in melee combat.
