KC mass production Disk The KC mass production Disk is the second Duel Disk model made by KaibaCorp . It was first issued to participants of the Battle City tournament . It is prominently used throughout the " Yu - Gi - Oh ! " second series anime . Characteristics . 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 ; whether this limits to a maximum of five cards on the field per player or not is not determined . Directly underneath each monster slot is another slot for Spell and Trap Card s . 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 Arena s if one player opted not to use a Duel Disk . The Disk is able to eject cards the Duelist wants into their hand . History . 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 . These Duel Disks were the only model used until Doma used the Chaos Duel Disk . 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 ! GX " these Duel Disks were used by the students at Duel Academy prior to being given the Academia Disk s . 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 . In " Yu - Gi - Oh ! ARC - V " , this model of Duel Disk was seen being used by the people of the Standard Dimension before Leo Akaba reinvented the ARC System . In " Yu - Gi - Oh ! VRAINS " , the body of the Duel Disk used by Yusaku Fujiki is similar to this model . Real world . 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 : Non - canon appearances .
