Zombies are undead beings created through the reanimation of a human corpse. They appear in The Mummy. Unlike most versions that are a result of science and/or disease, these were created by Ahmanet who drained the lifeforce from her victims and then brought them back with magic.
The Zombies first appear when Ahmanet is released from her sarcophagus after the plane crash. Still weak from her mummification, she starts sucking the lifeforce from people to regain her lost powers.
