Life Model Decoy
A Life Model Decoy (or LMD for short) 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 or strong EMP, they are indistinguishable from the original.

As an android, a Life-Model Decoy possesses all of the various superhuman attributes:
- Superhuman Strength - An LMD is super-strong and possesses strength beyond the human limit.
