Hold discussions about the Millenium series. These movies are unique, as most of them are their own movie, with no sequels (with one exception), and all are direct sequels to the original movie, though Final Wars appears to be more a sequel to an alternate version of the second movie. Movies in the Millenium series include:
Godzilla 2000 (1999)(lol?) · Godzilla vs. Megaguirus (2000) · Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack (2001) · Godzilla Against Mechagodzilla (2002) · Godzilla: Tokyo S.O.S. (2003) · Godzilla: Final Wars (2004)
