The Gundam Series (ガンダムシリーズ Gandamu Shirīzu?) is a metaseries of space opera anime created by Sunrise studios that features giant robots (or "mecha") called "Mobile Suits" (MS); usually the protagonist's MS will carry the name Gundam.
The metaseries started on April 7, 1979, as a serial TV show called Mobile Suit Gundam. That first TV series has since spawned a franchise that has come to include works released in numerous media. Titles have appeared in the form of multiple television series and OVAs, movies, manga, novels and video games, among other modes. The story from the original 1979 series has been considerably extended with sequels, prequels, side stories and alternate timelines. As a result, the title Gundam has become a collective term for the seven distinct but related timelines that can be pieced together from the stories that appear in the Gundam franchise.
The original timeline for the Gundam series was the Universal Century (UC) series, which included Mobile Suit Gundam (1979) and Mobile Suit Zeta Gundam (1985). Since the 1990s, alternative timelines have been produced and developed, including the Future Century, After Colony, After War, Correct Century, Cosmic Era, Anno Domini and Advanced Generation timelines.
