Notation Listings are broken up by television series. However, this does not mean that there aren't continituty overlaps. For example, The Gransazers (2003), The Justirisers (2004) and Super Fleet Sazer-X (2005) all appear as part of the Super Star God franchise. Furthermore, some characters overlap between those series. In the event of this, there will be a listing in each series list although they might lead to the same bio. The "year introduced" tag also references the year the episode from that series debuted in which the character was introduced. For example, the Showa King Ghidorah was introduced in Ghidorah, the Three-Headed Monster (1964) but is cited here as being introduced in 1973 as that's when the first Zone Fighter (1973) episode with the character aired. These listings are primarly of TV shows, although do include attractions, a few direct to video movies and also one theatrical film, Super Fleet Sazer-X the Movie (2005).
