KC mass production Disk
It is prominently used throughout the Yu-Gi-Oh! second series anime.
Unlike the previous Duel Disk, it did not need to be thrown. When it first appeared in the anime, sealers flew out of the Duel Disk to the sides of the Dueling area to produce the Solid Vision holograms. These were removed later. In the manga the holograms were projected straight from the Duel Disk itself.
The Monster Card Zone is along an arm blade. The Spell & Trap Card Zone is a series of slots behind each Monster Zone. In the anime, the blade could be folded up when not in use. In the manga, it could not be folded up, nor do the sealers that produce the Solid Vision make an appearance. In the manga, there is no Spell & Trap Card Zone slots, but instead the Monster Card Zone serves an all purpose for every card, meaning that both players are limited to five cards. The manga and anime designs of the Battle City disk are notably different in other ways: the manga design is a single solid piece, while the anime design "folds" into a more compact shape when not in use.
Directly underneath each monster slot is another slot for Spell and Trap Cards. If a Duelist was to activate a Set card, they would activate a button on the round portion of the disk. Another slot can open on the front end of the disk that is used for the Field Spell Card. The center of the disk includes the Main Deck and Graveyard slot and Life Point counter. The bottom part of the Disk, which goes around the user's arm, also contains a retractable cable that could be attached to Dueling Arenas if one player opted not to use a Duel Disk.
The Disk is able to eject cards the Duelist wants into their hand.
Prior to the Battle City Tournament, KaibaCorp developed the second generation Duel Disk, the first one to be released to the public, which were issued to the participants of Battle City. Originally, only those of eligible ranks to participate in Battle City (at least Level 5 out of 8 stars in the original, or at least 4 out of 5 stars in the dub) could apply for a Duel Disk. After the tournament was over, the device was distributed to public. The disk accepted counterfeit cards printed and used by the Rare Hunters; whether this is an oversight or intentional is unclear, but Kaiba did mention that one of the reasons for the tournament is to flush out the Rare Hunters, so the latter is probable.
In Yu-Gi-Oh! R, Richie Merced wielded a Black Disk, a special one-of-the-kind Duel Disk that only the strongest individual of the Card Professors Guild is allowed to wield. It is a KC mass production Disk with jet black colors, produced by Yako Tenma. Keith Howard defeated Richie and took the Disk for himself, only to lose a duel (and the Disk) to Katsuya Jonouchi, who gave it to Tilla Mook as returning the Duel Disk he borrowed from her earlier. Tenma installed an anti-cheat alarm onto the device, making it unable to accept cards that were not drawn from the Deck, as Keith found out when he attempted to sneak a "Ring of Destruction" from his wristband onto the zone.
In Yu-Gi-Oh! 5D's, this version of the Duel Disk was used by citizens of Satellite, while the people in New Domino City used more modern versions. Yusei Fudo uses a modified version of this Disk, while Jack Atlas's Disk resembles this one in style, but with a straight edge.
The toy company Mattel produced replicas of this Duel Disk. There are a couple of notable differences between the Mattel Duel Disk and its fictional counterpart. Spell and Trap Cards are loaded into the bottom of the blade (the opposite side to the anime version). Most notably, it cannot project holographic images. Also, the edge is not shaped like a blade.
While the toy Duel Disk was advertised as being compatible with the TCG, there are a few flaws that make this impractical:
- Most players used card protectors to prevent damage to their cards. Cards in protectors will not fit into the Duel Disk. Unprotected cards may get corner damage from the monster holding tabs on the blade's upper face if not used carefully.
- The Deck Zone can only hold about 50 to 59 cards safely. The Academy Duel Disk can hold 65 cards in total. While most players stick to the minimum, there are those who use bigger Decks and cannot use the Duel Disk. Though, the new rules made a maximum of 60 cards making the limited holding capacity problem moot.
- The Graveyard can only hold about 20 cards. This would present a problem when playing against someone who relies on running an opponents Deck out.
- No place for the Fusion Deck or banished cards.
- This is also true in the anime, as banished cards are often seen placed into the Duelist's pockets.
- The Life Points counter can only go up to 9990 life points. While both players start with 8000, 4000 or 2000, it could rise to 9000 or 10,000+ Life Points due to card effects. The reason for the zero at the end is because while there are four buttons on the disk, only 3 of them change the counter, the last one lights up the display. This also serves the problem that some cards can cause the Life Points in the ones place to be a number different than zero.
- The way the Duel Disk moves from stand-by to in use is also different. In the anime, the Graveyard is locked over the Deck and the two field parts are retracted into the main part of the disk. When triggered, the field parts and graveyard are unlocked and the central piece rotates the graveyard and field into play position. The toy however does not have a rotating center and the two halves of the field aren't locked in closer to the central piece. When the player triggers the toy into play mode, the smaller half of the field, which is spring loaded, is released from it's lock at the same time as the larger half which has a weaker spring, and thus, the smaller part pushes the larger part into play position.
