The ZGMF-XX09T DOM Trooper is a prototype heavy mobile suit introduced in the anime Mobile Suit Gundam SEED Destiny. It is piloted by Hilda Harken, Mars Simeon and Herbert Von Reinhard.

A modified design of ZAFT's ZGMF-XX09T DOM Trooper Original Spec Type, the DOM Trooper is armed with an enhanced beam saber stored on the back-mounted EZ Wizard, a "Screaming Nimbus" in the abdomen, a handheld "Giga-launcher" capable of firing physical projectiles and high-powered beams, and a pair of shoulder-mounted CIWS. The DOM Trooper also mounts a defensive "Solidus Fulgor" beam shield generator, the same type used by ZAFT's ZGMF-X42S Destiny Gundam and ZGMF-X666S Legend Gundam, on each forearm. Its large body and legs mount numerous thrusters, giving the DOM Trooper excellent mobility in spite of its bulk. It also possesses a hovering system built into its legs for moving rapidly over land. As seen in the series, the DOM Troopers' capabilities far exceeds that of the mass production suits of ZAFT.

A trio of DOM Troopers can utilize a special attack known as "Jet Stream Attack", which allows them to combine the power of three mobile suits into one through a highly synchronized attack. This maneuver involves the three units attacking in rapid succession, with each using a different weapon, and the lead pilot activating the "Screaming Nimbus". The "Screaming Nimbus" produces a "cloud" of particles with both offensive and defensive capabilities that spread out to form a barrier around the DOM Troopers. This has the end effect of allowing the DOM Trooper to tear through groups of enemy units with ease while still having a certain level of defense from enemy fire.
