The Japanese Osiris card #G4-02

In the anime and manga Yu-Gi-Oh, Slifer the Sky Dragon is one of the three Egyptian God Cards (The other two God Cards are "The God of Obelisk" (Obelisk the Tormentor) and "The Sun of God Dragon" (The Winged Dragon of Ra).). In the original Japanese manga, it is called "オシリスの天空竜" (pronunciation: Oshirisu No Tenkûryû; lit: "The Heaven Dragon of Osiris") or "Saint Dragon - The God of Osiris".

Initially passed by Malik Ishtar (Marik Ishtar) to his "puppet" - the "Pantomime" (パントマイマー; a.k.a. Strings), it is the second God Card appeared in the manga. The two poles it represents are "goodness" and "evil".

Effects

Warning: Plot details follow.

(The effects stated in this section are based on the Japanese anime and/or manga of Yu-Gi-Oh!. The real Osiris card does not have any effect printed on it (see "The real Osiris card").

Abilities shared by all three God Cards

(The two abilities stated above are preferential to the one below.)

Note: In both the
manga and anime, during the duel between Yugi Mutou (Yugi Moto) and the "Pantomime", Yugi used the Trap Card "Spellbinding Hexagram" (六芒星の呪縛, a.k.a. "Spellbinding Circle". Effect(in anime/manga only): a chosen monster on the field cannot attack; its ATK is lowered by 700 points.) to stop Osiris 's attack. Although "Hexagram"'s effect was negated after 1 turn, it did affected Osiris. One may then conclude that the ability stated above is wrong. However, this is not true.

In fact, the reason behind this "contradiction" is that the author of Yu-Gi-Oh!, Kazuki Takahashi, somewhat considers "Hexagram" as a Spell Card in the card game. Although the phrase "Trap Card" did appeared on the "Hexagram" card in the manga, and all characters referred to it as a "Trap Card", it was still considered a Spell Card in terms of gameplay. Whether this contradiction is caused by that miswritten phrase, or that Mr. Takahashi forgets about what was indicated on the "Hexagram" card, or even that "Hexagram" is in fact a Spell Card with Trap properties(!) is unknown.

In fact, similar problems have appeared before in Yu-Gi-Oh! manga. In the double duel between Yugi Mutou-Katsuya Jonouchi (Joey Wheeler) team and the Paradox Brothers, the big brother of the brothers (the one with the Chinese word "迷" on his forehead) used "Release Spell" (魔法解除. Effect: negate all Spell effects received from your opponent. Note: the picture on this card is almost the same as that of "De-Spell" (魔法除去), but these two cards have different names and effects.) to destroy Yugi's "Hexagram" card (still indicated as "Trap Card"). However, unlike the previous case, this time the "contradiction" did not appear in the anime, as what was used there was the card "Remove Trap" (effect: destroy 1 face-up Trap Card on the field.) instead.

Unique abilities

According to the anime and manga of Yu-Gi-Oh!, the Osiris card has the following unique statistics (unlike most other cards, in both the Japanese anime and manga, the text on the God Cards are written in English):

With what are observed in various duels, a more complete description of Osiris 's abilities can be concluded:

Note: in the real Yu-Gi-Oh! card game, monsters can be summoned in either face-up or face-down positions. However, in the manga, monsters can only be summoned in face-up positions. (i.e., there's no Set or Filp Summon.) So, whether or not the word "summons" includes setting and Filp Summoning of monsters depends on individuals.

The real Osiris card

The real Osiris card was first released by Konami as a special pack-in Japanese card in the first version of the Japanese GBC game "Yu-Gi-Oh! Duel Monsters 4: Battle Record of the Strongest Duelists (最強決闘者戦記)Yugi/ Kaiba/Jonouchi Version" in December 2000. It was released again by Konami in March 2003 as a special pack-in card in the Japanese GBA game "Yu-Gi-Oh! Duel Monsters International - Worldwide Edition" (Japanese version of another GBA game "Yu-Gi-Oh! Worldwide Edition - Stairway to the Destined Duel"), this time with both Japanese and English text printed on it.

The real Osiris card, regardless of which version, is ILLEGAL in all official tournaments. This is mainly due to the following reasons:
