This page is in need of a major rewrite, which it will get eventually.
Sailor Stars
The anime series hadn't finished when the Sailor Stars myu came out, but the basic plot is similar to the anime -- only there is no Kakyuu. The Starlights arrive on Earth, and Galaxia sends out her soldiers to collect the Sailor Crystals of the planet. Galaxia isn't defeated at the end of the series, she manages to kill almost everyone but Sailormoon fights back and Galaxia flies away.
They use the idea of time travel in this myu deciding that if they destroy Sailormoon in the past she won't exist in the future.
The galactica soldiers are called Galactica Sailor Soldiers, and they consist of: Sailor Iron Mouse, Sailor Tin Nyanko, Sailor Pewter Fox, Sailor Titan Kerokko, Mc Fly, Sailor Buttress, Sailor Theta, Sailor Phi, and Sailor Chi.
Eien Densetsu and Eien Densetsu Revised
(written by a friend)
The number of her soldiers is reduced to Sailor Tin Nyanko, Sailor Titanium Kekkero, Sailor Theta, Sailor Phi and Sailor Chi. Queen Beryl's minions are, Kunzite and Zoicite. Chaos is also in this Myu, but its intentions stay secretive until the end. Galaxia makes a deal with Beryl to work together to destroy Sailor Moon and her Soldiers, and Beryl agrees. Tuxedo Kamen is killed in the beginning, being revived as a Soldier working for Galaxia. Galaxia though, "gives" him to Beryl. The truth about Galaxia is revealed to Beryl by Sailor Pluto, which is the fact that she is merely "using" her and will eventually turn on her. Beryl does not see this truth until herself and both of her generals are attacked by Chi, Phi, and Theta. As the three Soldiers struggle, Galaxia does nothing to help her own minions out, leaving them to be defeated. After they are defeated, she herself proceeds to destroy Kunzite and Zoicite. When Tuxedo Kamen is sent out to kill Sailor Moon, Beryl protects her. As he is about to strike her with a fatal stab, she takes the hit for her, thus ending her life. She also learned that Tuxedo Kamen/ Endymion never did care for her, and was just an act on his part from being revised under Galaxia's control. In the end Tuxedo Kamen is healed, and Sailor Moon goes to face Galaxia for a last time. Galaxia though, is healed turning into "Sailor Galaxia". Chaos reveals its true intentions and attacks Sailor Moon. Sailor Galaxia though, saves Sailor Moon, proceeding to attempt to "seal" Chaos like she did in the past. Her attempts fail, and Sailor Moon is left alone with the Sailor Star Lights to defeat Chaos herself.
In the revised version of "Eien Densetsu" the only difference is that just Beryl herself is revised, and Galaxia does not have Sailor Tin Nyanko and Sailor Titan Kerokko. The same fate overall happens.
Shin Densetsu Kourin
This myu is quite different from "Sailor Stars" and "Eien Densetsu". For one, when Queen Beryl is revised, so is the Amazon Trio. The Amazon Trio is originally working under Queen Beryl, but betray her when Galaxia once again turns on her. Now you are probably wondering why Galaxia would turn on her if they are basicaly working for the same agenda, correct? Well like always, when you have no more use to Galaxia, she will kill you. The Trio originaly turn the Sailor Moon's Soldiers under Beryl's control, but when they switch sides they turn them Galactic. In the end like Sailor Uranus and Neptune attempted, they try to use Galaxia's power against her. Of course it is to no avail, because Galaxia possessed no "Sailor Crystal".
The end results in Beryl's death, and Galaxia being turned good. Sailor Moon is attacked by Chaos, and Sailor Galaxia helps her thus going after Chaos herself. The Trio in turn go after Galaxia to try to defeat Chaos as well. Once again Sailor Moon is left to fight alone. After Chaos is defeated, Sailor Moon revives the fallen soldiers.
Starlights ~ Ryuusei Densetsu
I'm not sure of the plot, but it seems to be another version of Sailor Stars. The Sailor Animamates to appear in this one are: Sailor Aluminum Seiren, Sailor Lead Crow, Sailor Iron Mouse, and Sailor Metal Papillon. Kakyuu doesn't appear in this story, but the Starlights do.
Kakyuu Ouhi Kourin - The Second Stage Final
Almost exactly the same as Ryuusei Densetsu except Kakyuu does appear. Galaxia also seems to turn into Sailor Chaos in this one.
