Kaite gives his second ZAKU to another mercenary, Serpent Tail member Elijah Kiel, after accidentally destroying Elijah's beloved customized ZGMF-1017 GINN. His ZGMF-1001 ZAKU Elijah Kiel Custom replaces the hand grenades with hardpoints for a GINN's heavy sword and incorporates a variation of Trans-Phase armor. While most Trans-Phase equipped mobile suits are permanently set in a particular color scheme, Elijah's ZAKU is normally gray and briefly turns red when hit by enemy fire. In addition, Elijah's ZAKU includes his trademark "buster sword" head fin and can mount 3-tube "Pardus" missile launchers on its legs, as well as a customized flight-capable Wizard Pack. The shoulders can also be fitted with small beam cannons, removing the shoulder shield in the process.
The ZAKU Elijah Kiel appears to be a modified version of the all around unit, the ZAKU Phantom. One of the major modification is the Trans Phase Shift armor system, making this variation the superior of all ZAKUs in terms of armor. Elijah's ZAKU, besides being able to mount the standard, Blaze, Gunner, and Slash Wizard packs, it is also equipped with its own custom Wizard pack. This Custom Pack grants the Elijah Custom greater mobility similar to the Blaze Wizard pack but features more thrusters and two side mounted beam cannons for extra firepower.
- MMI-M633 Beam Assault Rifle
- The same model of the beam rifle used by the regular mass produced ZAKU. It also has the high rate of fire as the ZAKU's.
- MA-M8 beam tomahawk
- The same model of the melee weapon of the ZAKUs mounted on the shield. However unlike the ZAKU, Elijah Kiel uses the Tomahawk as a thrown weapon.
- MA-M3 Heavy Sword
- Because Elijah had previously owned a GINN, the heavy swords were then transferred to the more powerful ZAKU and still functions the same.
- M68 Pardus 3-barrel Missile Launcher
- A similar version of the leg-mounted missile launchers of the GINN Assault Type is still available for the Elijah Kiel custom.
- M68 Cattus 500mm Recoilless Rifle
- The same model of beam rifles that is used by the GINN Reconnaissance variation are still used the same way as the ZAKU.
- Beam Cannon
- A pair of beam cannons which the ZAKU Elijah Kiel Custom can equip, these weapons are shoulder-mounted, meaning the ZAKU cannot equip its shoulder-mounted shield as well as both cannons.
Because Kaite Madigan had unintentionally disabled Elijah Kiel's GINN, Kaite had given Elijah one of his own ZAKU's in debt. Elijah had then proceeded to install the Trans Phase Shift armor into the ZAKU and improve it's armaments with the leftovers of his GINN. It was later replaced when Elijah had acquired his own advanced mobile suit, the Vent Saviour Gundam.
