MS-13 Gatsha
Also known as the Gasshia, it is a compact Zeon Mobile Suit originally created as an amphibious unit and later developed as a close quarters Space attack mecha. It is armed with dual Missile Pods, Claws and a powerful short-ranged Spiked Mace launcher gun (called the "Hammer Gun").
It somewhat resembles the Spartan Destroid mecha from Choujikuu Yousai Macross.
