The FA-010A (FA-010B) FAZZ is a prototype mobile suit from the Gundam photo-novel series Gundam Sentinel. According to the designer Katoki Hajime, the FAZZ was a testbed unit designed by Anaheim Electronics to test out several of the features that would be put into use when they would construct the FA-010S Full Armour ΖΖ Gundam. The acronym FAZZ (pronounced as "fahts") stands for Full Armor ΖΖ. The FAZZ tested the concept of adding extra armour components to critical structural points to make the unit more structurally sound. However, the FAZZ itself had the necessary equipment to transform into the G fortress removed to simplify construction costs, and the armour components of the FAZZ can not be removed or ejected, so the unit is incapable of transforming and combining into G-Fortress mode like the standard MSZ-010 ΖΖ Gundam was capable of doing. Also, the FAZZ's High Mega Cannons were totally inoperable. While the back-pack rods resembling the Hyper Beam Sabers equipped by the ΖΖ, they were instead Beam Cannons derived from S Gundam's back pack cannon.
The feature of this variation is the second most powerful Hyper Mega Cannon(official output of 79.8MW) for long-range fire support.
