There was also an added stipulation: if one of the protagonists were to lose, the Big 5 also threatened to take their bodies for themselves and escape into the real world. To do so, they force their participation in their own virtual Duel Monsters tournament, in a similar vein to Kaiba's Legendary Heroes games. The Big 5 seek revenge against Kaiba, as well as Yugi Muto for foiling their plans to take over the company on two different occasions (by defeating Maximillion Pegasus and the Big 5's Mythic Dragon in Legendary Heroes). Forcing many of its passengers off the ship, the mysterious force leads them into another room, where they reveal themselves to be the Big 5, who are the five former board members of KaibaCorp, who were fired by Kaiba before the Battle City tournament for attempting to take over his company from underneath him. However, the trip takes a mysterious wrong turn, and finds itself landing in an undersea fortress - apparently, a mysterious force is set on revenge against Kaiba. The Virtual World arc can be seen as a sequel to the Legendary Heroes arc (episodes 43-45) as it features The Big Five looking for revenge within a virtual reality system similar to the one they were defeated in.Īboard Seto Kaiba's airship, the eight Battle City finals Duelists prepare to head for Alcatraz ( KaibaCorp Island in the English dub), the site of the semifinal and final rounds of the Battle City tournament. When a member of Yugi's group Duels in this Virtual World, he/she is given a Duel Disk by their opponent, and they must build a new Deck. It is also not known whether a Deck Master card counts as against a Duelist's main (or Fusion, if the Deck Master is a Fusion monster) Decks, as this concept is not elaborated upon in the anime.

It is not explained how a monster that cannot be specially Summoned, or a monster that can only be Summoned in a special manner (such as "Fusion only") can be designated as a Deck Master, as no such monster was used as a Deck Master in the story arc. If the Deck Master is itself Tributed or otherwise replaced, the new monster would become the new Deck Master, and the old Deck Master's abilities were lost (in theory, the old Deck Master could be returned by normal means - but without the Deck Master abilities, although this point is not elaborated upon in the story arc).

However if the Deck Master is destroyed, its controller automatically loses the Duel. The Deck Master can also be specially Summoned to the field, without any prerequisite such as Tributes, Fusions (for Fusion Monsters) or rituals (for Ritual Monsters). As well, it appears that some Deck Masters retain their normal special abilities to be used as their Deck Master abilities, such as " Jinzo's" ability to negate all Trap cards and Nightmare Penguin's ATK increase of all WATER-Attribute monsters. It is to be noted that even Deck Masters which otherwise have no special abilities (such as Normal Monsters) have a special Deck Master ability. Each Deck Master has a unique special ability, which can be used at any point in the Duel as many times as desired. In these Duels, each player would select a Deck Master, which begins the game outside of the playing field. The large majority of the story arc revolves around a new gameplay element, which is created specifically for this story arc, known as the " Deck Master".
