Jeff is a 200 meters long, worm-like alien living in abandoned subway lines on New York City. The name of his species has never been revealed.

Biology[edit | edit source]

Jeff is most likely lithotrophic as it has been mentioned that he eats inorganic garbage and he was seen biting off half of a subway train. He has an elongated body with no visible appendages; a large, four-mandibled mouth filled with thousands of sharp teeth; a pair of small eyes and a short, flower-mimicking antenna.

History[edit | edit source]

Jeff is one of the many extraterrestrials whose existence is kept in secret by the Men in Black. Zed mentioned that he remembers when Jeff was as small as a regular Earth worm, implying that Jeff may have been born on Earth, or lived on it for most of his life.
