The Gump is a heavily-customized MSZ-010 ΖΖ Gundam piloted by an aged Judau Ashta in the Mobile Suit Crossbone Gundam: Skull Heart side-story and Mobile Suit Victory Gundam Side Story A unit featured first in Mobile Suit Crossbone Gundam: Skull Heart, the machine was piloted by Grey Stoke (supposedly a 60-year-old Judau Ashta). The unit is battle-worn, and has been repaired with many junk-parts in order to maintain a barely-humanoid shape with different arms and legs. The head remains disguised as well, and yet the body and double beam-rifle (and the pilot) strongly hint that the unit is indeed the ZZ Gundam. The same unit, which obviously received further repairs, was also seen in the Mobile Suit Gundam V side story written by the same author as Skull Heart. This time, the pilot is almost 20 years older. The head of the unit was still disguised, but was forced to fire its hidden High Mega Cannon, breaking apart the disguise to reveal the head of ZZ Gundam. The suit's power was not enough to support the more-than-60-year-old cannon, and could only light up the battlefield. Still, it revealed the true Zong from its illusions, and helped Uso Ewin defeat the enemy.
