"Legendary Planets", known in Japan as the "Planet Series" (Ｐ(プラネット)シリーズ, Puranetto Shirīzu), are a major plot point from the Yu-Gi-Oh! GX manga, which were created by the father of Aster Phoenix while he was possessed by Tragoedia. The series consists of ten powerful cards, each analogous to one of the planets in the solar system at the time of the manga's first release, although, strangely enough, it also includes the sun. The cards are named accordingly, with all of them possessing some sort of reference to their respective planet (or star in "The Sun's" case) within their names and card arts. Though not initially revealed, all the cards in this group have an ability that saps small amounts of energy from duelists who wield them. This energy was used by Tragoedia to unleash his heart from "Winged Kuriboh".

NamesEdit

In the OCG and Japanese manga, the Planet Series naming convention is The (adjective) PLANET (with the exception of "Terra Firma", whose OCG name is "Elemental Hero The Earth"). The words are written in upper case English. In the English manga, the word "the" is removed, whereas in the TCG, with the exception of "Venus" (who is just called "Splendid Venus"), the names are kept the same as the OCG name, minus the capitalization. "Terra Firma" was used in place of "The Earth" for unknown reasons.

MembersEdit

In the GX manga, Alexis Rhodes has faced many of the revealed Planet cards, and she has lost each match when she faced one. In her match with Jaden Yuki, she fought "Terra Firma". Against David Rabb, she lost to the "The Big Saturn". And she also lost to Reggie MacKenzie, who used "The Splendid Venus". She later faced Aster Phoenix in the American vs Japanese one-on-one matches, and lost to his newly obtained Planet "The Grand Jupiter". The fifth monster of this series, "The Tyrant Neptune" is used by Jim Crocodile Cook in his Duel against Atticus Rhodes. But unlike his sister, Atticus won his match against a Legendary Planet. The sixth monster, "The Despair Uranus" is used by Adrian Gecko against Jaden, however, Jaden managed to defeat The Despair Uranus and Adrian. "The Tripper Mercury", the seventh Planet monster is used by Jesse Anderson to defeat Syrus Truesdale. Chazz Princeton managed to defeat Axel Brodie and the eighth planet card, "The Blazing Mars".

In chapter 54, Aster Phoenix was given the last card of the planet series by Principal MacKenzie. Four chapters later, it is revealed that he was given "Jupiter". "The Suppression Pluto" was used by Atticus. Chapter 60 reveals that Principal MacKenzie himself holds "The Supremacy Sun", a card based on the star at the center of the solar system, which keeps all the planets in place rather than a planet itself.
