Star Trek

Star Trek is one of the most famous science-fiction continua. It was created by Gene Roddenberry. The basic premise is that in the future, Earth and a number of other planets form the Federation, with a military/exploration arm known as Starfleet. Most of the series feature a crew of humans and other creatures on an exploratory vessel, charting unknown space, aiding those in danger, and getting into scientifically slightly-implausible but very exciting scrapes, from which they always escape narrowly.

The Original Series
This starred William Shatner as Captain James T. Kirk, with Leonard Nimoy as Spock, voyaging on the starship Enterprise. Fan magazines often published fanfiction of these two characters in a romantic or physical relationship; the term slash to designate male/male pairings originates here. The original Mary Sue also appeared in TOS fanfiction, as a parody of the common archetype.

The Next Generation
Patrick Stewart stars as Captain Jean-Luc Picard of the starship Enterprise (the fourth or fifth vessel to bear this name since the days of the now-legendary Kirk).

Deep Space Nine
The only series not set on a ship; this follows the adventures of the crew of the space station Deep Space Nine.

Voyager
Kate Mulgrew stars as Captain Kathryn Janeway, of the starship U.S.S. Voyager, which is catapulted to the Delta quadrant and must make its way home over unimaginably vast distances.

Enterprise
A prequel series, set before the time of Kirk.
