A mass production combat MS created by Mars Zeon in the U.C. 0110s-0120s. It is the result of combining MS technology brought by former Zeon/AEUG veterans, movable frame TR-1 series tech by former Titans exiles, as well as original Zeonmobile suit designs with modern designs like the AMS-119 Geara Doga. Although its outward appearance was virtually identical to the original MS-06 Zaku II (but the outside pipes are all dummies), it was constructed from modern materials making it much lighter.
Similarly, its internal components were based on the Geara Doga's and because of improvement in technology, the RF Zaku not only had a higher performance than the original Zaku, but it could even out-perform the Geara Doga in some areas.
