The ZGMF-X19A ∞ Justice Gundam (aka Infinite Justice, Justice) is the successor to the ZGMF-X09A Justice Gundam introduced in the anime Mobile Suit Gundam SEED Destiny. It is piloted by Athrun Zala.
Developed as a successor to the ZGMF-X09A Justice Gundam, the ZGMF-X19A ∞ Justice Gundam also incorporates technology from ZAFT's Second Stage Series such as the Variable Phase Shift armor. Adjustments were made to reflect Athrun Zala's combat data, practically making the ∞ Justice his dedicated mobile suit. The ∞ Justice's close combat capability is enhanced over its predecessor's and is armed with a number of unique weapons such as leg beam blades and a carrier beam shield that is a combination of a beam shield, a beam boomerang and a grapple stinger.
The ∞ Justice carries on its back a flight unit that can be deployed as a separate support unit/subflight unit. This Fatum-01 is an improved version of the original Justice's Fatum-00 with higher overall performance, and is armed with a pair of beam cannons as well as several beam blades. The suit can dock with the METEOR unit for additional firepower as well as speed, and can fire at multiple enemy units simultaneously using the Multi Lock-On System. As with the Justice, ∞ Justice is design to operate alongside another mobile suit, in this case, the ZGMF-X20A Strike Freedom Gundam, and is stationed on board the warship Eternal. Like the Strike Freedom, the ∞ Justice is equipped with Neutron Jammer Canceller, Hyper-Deuterion Engine, and has joints as well as inner frame made of PS armor materials.
The Hyper-Deuterion Engine is a new type of nuclear reactor and due to its massive output, the ∞ Justice has extremely high mobility and maneuverability. Meanwhile, the phase-shifting of its joints and inner frame as a result of the PS armor materials give them strength and near human flexibility while also enhancing the suit's combat abilities. Additionally, the ∞ Justice is able to discharge excess residual energy within the body through the joints' glowing effect, which is silver instead of Strike Freedom's gold. The ∞ Justice has a shorter V-fin than its predecessor as the performance of the sensor unit within the head crest has been greatly enhanced.
