The Zaku I was the world's first nuclear-powered MS to achieve combat status in the UC timeline. Developed from the Zaku I was developed from the MS-04 Prototype Zaku, and featured technologies that would become standard in all mobile suits. The MS-05A ran a thermonuclear reactor developed and manufactured by the ZAS company that provided the Zaku I with an unlimited power source. The reactor was cooled by stored liquid hydrogen during missions in space, and an air-cooled system when operating on Earth. The Zaku I used the head-mounted Mono-Eye camera system, which was used in conjunction with several cameras mounted around the mobile suit's body and granted the pilot excellent visibility from the enclosed cockpit. The Zaku I also incorporated laser sensors, infra-red sensors, and a powerful computer to facilitate the MS' operation. In combat, the Zaku I is an effective melee fighter. A reference to the original anime, the Zaku I's tackle is highly destructive and can do very good damage at higher levels when paired with the tackle damage parts. Zaku I pilots must be cautious though because the defense and HP ratings of this MS are some of the lowest in the game. This is countered by the very low bounty for this MS. At low levels, this MS respawns before the pilot.

Tips and StrategiesEdit

The Zaku I is very weak compared to most other suits in almost every category. Even though it is a melee type, the 2-hit combo with its heat hawk does not do much damage, roughly 800 points per hit. Its main strength is that it is cheap, about half the cost of its successor, the Zaku II at level 1, and thus, its respawn time is very short. It is best used as a short range support unit.

Although being weak in most fields, if paired with a tackle damage part, it's tackle is lethal, use it's tackle very wisley to do heavy damage.
