The "ZAKU", an acronym for "'ZAFT Armed Keeper of Unity", is the main mobile suit of ZAFT during the Second Alliance-PLANT War.

A notable feature of the mass production ZAKU is its ability to use interchangeable Wizard Packs similar to the Striker Packs of the GAT-X105 Strike Gundam.


Created sometime after the end of the First Alliance-PLANT War, the ZAKU series included the ZGMF-X999A ZAKU Mass Production Trial Type which was produced prior to the signing of the Junius Treaty, and its successors which were designed to comply with the Junius Treaty: the ZGMF-1000 ZAKU Warrior and ZGMF-1001 ZAKU Phantom as well as their variants. When ZAFT held a competition to determine the first MS in the New Millenium Series of next generation mass production MS, the ZAKU Warrior participated and defeated the initial design of ZGMF-X2000 GOUF Ignited and ZGMF-XX09T DOM Trooper Original Spec Type.

Several units based on the ZAKU series would serve as a testbeds for experimental weaponry and design features that would be used in later Gundam-type mobile suits. The ZAKU Splendor is used to create the ZGMF-X56S Impulse Gundam, while the Providence ZAKU would be developed into the nuclear powered ZGMF-X666S Legend Gundam.

  • ZAFT's ZAKU is an obvious homage to the Universal Century's Zaku. The Trial Mass Production ZAKU has similarities to the MS-05 Zaku I while the ZAKU Warrior bears the greatest resemblance to the MS-06 Zaku II.
