JSM-08 Zogok

The JSM-08 Zogok was an extremely powerful aquatic Mobile Suit developed from the JSM-07 Zgok. It outmatched the Allied UAG-79 Aqua GM and had equal performance to the Gundiver.

History
The Zogok was first seen during the Battle of Leyte Gulf where it took down several squads of UGM-79 GM's and even a Gundam FSD. Despite their performance, they were not enough to win the war as they were produced too little, too late.

Many more of these units were produced by Japan in the 21st Century and are the backbone of the Japanese Navy
