Infinite Justice's Fatum-01 subflight lifter is armed with two beam cannons, two short beam sabers mounted on the back of the two beam cannons, a nosetip-mounted beam saber and two wing-mounted beam blades similar to those of the ZGMF-X88S Gaia. Its joints are silver in colour, while its companion and counterpart unit ZGMF-X20A Strike Freedom has gold joints and hands. Like its predecessor, the Infinite Justice can dock with a METEOR unit. The ZGMF-X19A Infinite Justice uses an updated version of the operating system Generation Unsubdued Nuclear Drive Assault Module (GUNDAM) complex.
Infinite Justice makes its debut in Cosmic Era 74, arriving on Earth together with the ZGMF-X20A Strike Freedom during the ZAFT invasion of Orb. It is delivered to Athrun Zala personally by Lacus Clyne, who pilots the Infinite Justice through atmospheric re-entry and lands in the Archangel's mobile suit hangar to give it to Athrun. After talking with Lacus, Athrun takes off in the Infinite Justice to back-up Kira in the Strike Freedom, who was battling both the ZGMF-X42S Destiny and the ZGMF-X666S Legend and manages to chop off Destiny's wrist despite Athrun being injured before the fight. The Justice also plays a highly prominent role in the end of the Second Bloody Valentine War. First, Athrun disables both Shinn Asuka's Destiny and Lunamaria Hawke's Impulse; he then cripples the Minerva by utilizing the multiple beam cutters on the Justice's Fatum-01 backpack to destroy the Minerva's spaceflight engines. Lastly, Athrun used the Justice's backpack, along with help from Mu La Flaga's ORB-01 Akatsuki's DRAGOONs, to destroy Requiem. In Gundam SEED Destiny "Final Plus", when the battle is brought to an end, the Infinite Justice rescues both Shinn and Lunamaria.
