The G Eliminator has an attack called Stranglehold that causes massive damage to Zack. To protect himself from this, Zack should cast Regen and Wall as soon as possible. Despite the G Eliminator's high Attack and Magic stats, it is easy to defeat because of its low Spirit and Vitality stats. Therefore, a single Hell Firaga will likely deplete around 9,999 HP, and a critical hit will deplete around 7,000 HP. The amount of damage Zack can deal to the G Eliminator is dependent upon his stats, however.
