'''''Yu-Gi-Oh!''''' (遊☆戯☆王 ''Yūgiō'', translit. "King of Games", occasionally called "''Yu-Gi-Oh! A Game of Darkness''", "''Yu-Gi-Oh! first season''", or "''season zero''" by fans) is the title of the first anime series based on adaptation of the [[Yu-Gi-Oh! (manga)|''Yu-Gi-Oh!'' manga series]]. The 27-episode series was produced by [[Toei Animation]] and aired on [[wikipedia:TV Asahi|TV Asahi]] from April 4 to October 10, 1998.

While this series is not directly connected to ''[[Yu-Gi-Oh! (second series anime)|Yu-Gi-Oh! Duel Monsters]]'' (known internationally simply as ''Yu-Gi-Oh!'', produced by [[wikipedia:Nihon Ad Systems|Nihon Ad Systems]] and aired on [[wikipedia:TV Tokyo|TV Tokyo]]), both anime series are based on the ''Yu-Gi-Oh!'' manga. To distinguish the two series, some fans refer to this series as "Season Zero"; however, it is a different series entirely, not merely an earlier season of ''Yu-Gi-Oh! Duel Monsters''.

Manga plots were re-written so that they could take up an entire episode's worth of time. Also, the level of violence was reduced between the manga and the anime. Finally, a minor character in the manga, [[Miho Nosaka]], became a main character in the first This series along with [[Yugi Mutou]], [[Katsuya Jonouchi]], [[Anzu Mazaki]], and [[Hiroto Honda]]. Characterization was slightly modified. For instance, Miho is a "ditz" in the anime while in the manga she is a shy student librarian. Also, Honda is Jonouchi's verbal sparring partner instead of his crony has never been released in Toei's animeEnglish.

New characters and ==Adaptation==Manga plots, such as those relating to the four game masters, were added, and there are more occurrences of [[Seto Kaiba]] and re-written so that they could take up an entire episode'''Duel Monsters''' ('''''Magic and Wizards''''' in the original Japanese manga) than in the corresponding manga. Unlike the second series, the card game (Duel Monsters) is not the sole focus s worth of the show. Howevertime, and the Duel Monsters rules have been updated, becoming more like those used in the [[Duelist Kingdom]], even though this anime never gets to that point. The last episodes level of the series focus on the battle between Yugi and [[Dark Bakura]]. This series had different voice actors and different character designs than the second series (e.g. Seto Kaiba's hair is green in Toei's anime). The series has not been licensed for an English-language releaseviolence was reduced.

==Yami no Game==In this series[[Miho Nosaka]], Yami Yugi doesn't challenge people to who was a duel of Duel Monsters. Insteadminor character in the manga, he would challenge them to became a Shadow Game, or Yami no Game, where he would then explain the rules. However, the person main character in question would cheat and the Doors of Darkness will openanime series, thus Yami joining [[Yugi would do a Mutou (Toei)|Yugi Mutou]], [[Penalty GameKatsuya Jonouchi (Toei)|Katsuya Jonouchi]] upon the person, and whatever they obsess over the most would be their nightmare[[Anzu Mazaki (Toei)|Anzu Mazaki]], such as their makeup falling off and showing their true face or watches fusing to their being[[Hiroto Honda (Toei)|Hiroto Honda]]. Duel Monsters With her expanded role, her personality was not also changed; Miho is a "ditz" in the main point of anime, but in the show but was played manga she is a few timesshy student librarian. Additionally, Honda is Jonouchi's verbal sparring partner instead of his crony in this anime series.

New characters and plots, such as those relating to the four game masters, were added. While [[Duel Monsters]] (Magic and Wizards in the original Japanese manga) is not the sole focus of the anime, it and [[Seto Kaiba (Toei)|Seto Kaiba]] appear more often than they did in the corresponding manga arcs that were adapted. Duel Monsters' rules have been updated to more closely match the rules used in [[Duelist Kingdom]] in the manga, even though this anime series did not adapt the Duelist Kingdom arc. The series ends with the battle between Yugi and [[Dark Bakura]]. [[Nihon Ad Systems]]' ''Yu-Gi-Oh! Duel Monsters'' anime re-adapted the manga in a different way to this series. Voice actors and character designs differ from this series (e.g. Seto Kaiba's hair is brown instead of green). ==SeiyūShadow Games=={| borderIn this series, Yami Yugi doesn't challenge people to a duel of Duel Monsters. Instead, he would challenge them to a [[Shadow Game]] (''Yami no Game''), where he would then explain the rules. However, the person in question would cheat and the Doors of Darkness will open, thus Yami Yugi would do a [[Penalty Game]] upon the person, and usually whatever they obsess over the most would be their nightmare, such as their makeup falling off and showing their true face or watches fusing to their being. Duel Monsters was not the main point of the show but was played a few times.  ="1" style="background: #f8f8ff; border: 1px solid #88a; border-collapse: collapse;" cellspacingCast="1" cellpadding=The ending credits of each episode features three pages of voice roles.* Characters appearing on the first page are listed below as "2main".* Characters appearing on the second page, at least once, are listed below as supporting.* Characters only appearing on the third page are listed below as minor. {|- styleclass="background: #ccf;wikitable"!
