 Geordi LaForge has been promoted faster than any Star Trek character  before or since. In the first season, Geordi was a Lieutenant junior  grade; in the 2nd season, a full Lieutenant; 3rd season, a  Lieutenant Commander. (Other characters have had that many ranks,  but none were promoted as fast as Geordi was.)  _"Star Trek: Voyager" (1995) Timeless (#5.06)_ (qv), took place in  the future, where Geordi was a Captain.
