This gundam paper model is a SD MSM-07 Z'Gok, a mass production amphibious mobile suit, the papercraft created by jolulu. There are mass production and Char Aznable dedicated two versions. MSM-07 Z'Gok was first featured in the anime series Mobile Suit Gundam, and later appeared in the OVA series Mobile Suit Gundam Unicorn.
The Z'Gok's success came from what it learned from the Gogg's and Acguy's errors. The Z'Gok was very agile and fast in and out of water. MIP also replaced the bulky ballast water tanks used by the Gogg and Acguy for cooling off the mobile suit for out of water operations with an air cooling fan system. Notably, the weapon layouts were improved. Overall, the MSM-07 Z'Gok is considered the most successful amphibious mobile suit line produced by the Principality of Zeon during the One Year War.
Each of the Z'Gok's hands featured built-in mega particle cannons for easier and more precise aiming. Each hand also had three-claws which could be used to thrust into the Earth Federation's mobile suits or they could be used to smash things as well. The Z'Gok also had six 240 mm missile launchers built into the head with five rounds.
