The RX-79(G)Ez-8 Gundam Ez8 is a reconstruction of a heavily damaged RX-79(G) Gundam Ground Type using whatever parts the Earth Federation Forces engineers could find.
The resulting amalgam of spare parts was given the new model number RX-79[G]Ez-8, code named the Gundam Ez8 (Ez8 standing for "Extra zero-8"). The Gundam Ez8, despite being constructed largely of spare parts, was actually capable of a slightly higher performance than the existing RX-79[G] Gundam Ground Type. By removing the fixed weapons in the left side of the chest the Kojima Battalion engineers were able utilize the extra space to improve upon its power plant mechanism and boost reactor output, which gave the Gundam Ez8 a higher generator output, better propulsion, improved mobility, and superior overall performance. The Gundam Ez8's armor placement was also revised, giving it added protection around the cockpit block and chest, and around the ankles.
To compensate for the removal of the chest-based vulcan and multi-launcher cannons, the Gundam Ez8 had a 12.7mm anti-personnel machine gun placed in the mecha's abdominal region, as well as twin 35mm machine guns mounted in the head. The Ez8 still retained the two beam sabers stored in the compartments in the sides of the legs, and was still capable of using all of the armaments its predecessor could, although Shiro heavily favored the 100mm machine gun. The traditional Gundam "V-fin" communications array that was mounted on the forehead was also done away with, opting instead to replace it with a more durable and more function-efficient rabbit-ear communications antenna on the right side of its head. The Gundam Ez8's backpack design was left unchanged allowing it to still mount mission packs and other necessary field equipment options.
