MSM-03C Hygogg

The biggest obstacle for Zeon’s Earth invasion plan was to conquer the oceans. Therefore, many amphibious mobile suits were designed for effective combat performance under the waves. The high power generators required needed to be able to fit into the new, sleek, hydrodynamic body designs, yet maintain maximum power output. Some of the designs made using data gathered from experiments under the simulated oceans of space colonies proved to be failures (MS-06M Zaku Marine Type) under actual atmospheric operations, while others needed only minor revision. The MSM-03C Hygogg (as well as the MS-07E Z'Gok-E), falls into the latter category, being an overhaul of its successful cousin, the MSM-03 Gogg.

The MSM-03C Hygogg was designed to pair up with the MSM-07E Z'Gok-E, in the "Silent" operation under the command of U-boats (U-Con, Mad Angler, etc.). Depending on mission requirements, an underwater jetpack can be equipped for boosting up and jumping purpose.

With the revised mono-eye layout, better mobility through the redesigned shoulder armor, and its smaller size (total height 15.4 m compares to 18.3 of the original version), the Hygogg is one of the better amphibious MS designs produced during the One Year War. Its weapons included 4 torpedoe tubes, mounted in the head, an attachable hand missile unit, and beam cannons, mounted in the palms.

Many Hygoggs were designated to the territories of North America, South Africa, South Asia, and the Australian continent, the most famous of which being those assigned to the Cyclop team in an attempt to steal the RX-78NT-1 Gundam "Alex" prototype from the Federation's Arctic Base.
