Life Model Decoy

A Life Model Decoy (frequently known by the abbreviation LMD) is a fictional android appearing in American comic books published by Marvel Comics. LMDs duplicate all outward aspects of a real living person with such authenticity that they can easily impersonate a specific person without casual detection. LMDs first appeared in "The Man For the Job!", a short story by writer Stan Lee and artist Jack Kirby that ran in the anthology book Strange Tales #135 (August 1965), in which the spy agency S.H.I.E.L.D. created LMDs of agent Nick Fury to use as decoys for an attack by the terrorist organization Hydra.

LMDs have been used in numerous Marvel Comics storylines in the half century since their first appearance, and have also been adapted into other media based on Marvel, including films, television series, animation and video games.

Publication history
Life Model Decoys first appeared in "The Man For the Job!", a short story by writer Stan Lee and artist Jack Kirby that ran in the anthology book Strange Tales #135 (August 1965). The spy agency S.H.I.E.L.D. created LMDs of agent Nick Fury to use as decoys for an attack by the terrorist organization Hydra.

A Life Model Decoy is a S.H.I.E.L.D.-designed robot that duplicates all outward aspects of a living person. The owner can see through, speak through, and control everything the Life Model Decoy does. Nick Fury's Life Model Decoys are probably the most common in the Marvel Universe.

It is designed to function as an exact body double for VIPs. Their design is such that they mimic the subject's outer appearance (i.e., fingerprints, hair, all details of the skin), speech patterns, scent, iris and retina patterns, body language, thought patterns (to fool telepaths), and any other biological indicators. Aside from any invasive procedure and vulnerability to strong electromagnetic pulse, they are indistinguishable from the original.
