YRMS-106 Hi-Zack Pre-Production Type

The YRMS-106 Hizack Pre-Production Type is prototype mobile suit that appears in the novel Advance of Zeta: The Flag of Titans.

Technology & Combat Characteristics
Developed by Anaheim Electronics, the Hizack eventually became the company's first mass-produced mobile suit. Aesthetically similar to the famous Zaku II, the primary mobile suit of the old Zeon forces, this distinctive design could only have been created by Anaheim, which had merged with the Zeonic Corporation, once the Principality of Zeon's main mobile suit manufacturing firm. The Zeonic Corporation’s experience in mobile suit development is incorporated into the unit's overall construction, giving it the same high operating reliability, combat effectiveness and ease of production as the Zaku II, although mechanical reliability was not compromised. Featuring a modular construction, the Hizack is capable of equipping beam weapons and a host of various optional parts, it is also the first mass production machine to include a linear seat and panoramic monitor as standard equipment.

History
The Hizack entered service with the Earth Federation Forces in UC 0084, and a test evaluation unit was assigned to the Titans Test Team to investigate whether it should be adopted by the Titans as well. Its resemblance to the Zaku made the Hizack unpopular with the Titans, but their need to ensure a sufficient number of mobile suits for their growing organization, they are ultimately left with no alternative.

RMS-106C HiZack Cannon with Armor Unit
The “cannon pack” previously tested on the GM Sniper III can also be attached to the Hizack, which is unable to use multiple beam weapons at the same time, in order to increase its firepower. The Hizack was designed from its development stages to provide operational flexibility through this kind of modular replacement, and it can be adapted essentially without modifications by exchanging parts. Due to the subsequent appearance of mobile suits with higher generator performance which can use more beam weapons, this machine never enters mass production, but it’s used for rear support in certain operations. A detachable general-purpose armor unit can also be installed on its chest.
