YMMV: Queen Millennia
- Crowning Music of Awesome: Most people remember this series because of its hauntingly beautiful theme music by Kitaro.
- That'd be quite a feat, since he only performed the music for the film, not the series!
- Fanon Discontinuity: Many Matsumoto fans wish they had never made Maetel Legend due to the fact that it definitively shows Yayoi herself becoming evil and transforming into Queen Promethium of Galaxy Express 999-shades of Anakin Skywalker in Revenge of the Sith. Yes, there is a Palpatine type character that's responsible for this meaning that she is clearly manipulated into doing so. Previously, it was believed in fanon that Yayoi was instead the daughter of Promethium and that Yayoi would eventually become Maetel in 999.. Many prefer the 1982 Queen Millenia as the definitive resolution Yayoi sacrifices herself. End of story
- Idiot Plot: Several plot threads only work out because every faction forgets critical information they already have or ignore the obvious whenever it's most convenient for the plot.
