Zombie is a status in Final Fantasy VIII. The afflicted receives damage from curative items and magic and Regen, and is instantly killed by Life magic and items. Absorption abilities' effects are reversed. Targets under this status gain innate immunity to Instant Death and Doom, take double damage from Holy-elemental attacks, and halve damage from physical attacks (the in-game Information menu erroneously states that Zombie increases attack power).
The effect remains indefinitely, even after battle. Elixirs, Megalixirs, and Full-cure will completely reduce the HP of party members afflicted with Zombie, rather than prioritizing healing the status. Outside of battle, healing items and spells will have no effect.
Zombie halving physical damage received can be used defensively, as it also stacks with Protect. The player will not be able to heal with curatives, but can still heal by absorbing elemental damage with Elem-Def-J.
The Zombie effect can be useful against the Sorceress enemies who are not immune and they can then be easily dispatched with curatives.
