hizack
A fictional mecha from the Gundam series. It first appeared in Zeta Gundam from 1985.
RMS-106 Hizack
A mobile suit developed by the Titans based on the legendary Zaku II series from Zeon.
In order to snuff out the Zeon remnants, the Hizacks were made to greatly resemble the Zaku, but packed much more powerful beam weapons in addition to the Zaku machine guns. Earth Federation Hizacks are blue colored, while the Titans opted for the classic Zaku II green color scheme for their units. The Hizack replaced the GM Quel and was the standard Titans MS at the start of The Gryps War, but was quickly replaced itself by the Marasai.
After The Gryps War some grey colored units were seen deployed by the Neo Zeon Sleeves during their Attack on Torrington base.
