|Video game debut|
DarkNite, known as Card Majin in the Japanese version, is the main antagonist in a few of the Yu-Gi-Oh! video games. He is capable of transforming into a more powerful form known as Nitemare. Both forms are called Card Majin in the Japanese version. A majin is a malevolent deity that causes misfortune and disaster.
Yu-Gi-Oh! Forbidden MemoriesEdit
When Heishin awakens DarkNite, he attempts to order him claiming it is part of the pact, but Darknite says that he does not recall making a pact with Heishin. When Heishin begins to plea with DarkNite, he quickly grows tired of the conversation and turns Heishin into a card. Finding it to be nosiest and ugliest card he ever created, DarkNite burns it saying it doesn't deserve a place in his Deck.
DarkNite then turns to Atem and Seto saying that they would make nice additions to his Deck. Seto reminds Atem about the Millennium Item Cards. Atem then holds out the cards forcing DarkNite back. Unable to fully hold him back, the prince is left to duel DarkNite. After losing once DarkNite refuses to accept his defeat and turns into Nitemare demanding another Duel. Atem proceeds to defeat Nitemare, sending him back to where he came from.
The Falsebound KingdomEdit
In Yu-Gi-Oh! The Falsebound Kingdom, DarkNite is the final boss. He is described as a "dark spirit," who is turned loose by Scott Irvine after the hero (either Yugi or Seto) dismantles Irvine's virtual world, The Kingdom.
Though DarkNite has only one monster, it is one of the powerful Egyptian God Cards. Which god card is faced depends on the hero, and seems to correspond to the God each hero has the most rivalry with; Yugi faces "Obelisk the Tormentor,"and Seto faces "Slifer the Sky Dragon," After defeating him, The Kingdom is shut down once and for all.
DarkNite doesn't appear in Joey's storyline, since it is a prequel to Yugi's storyline, where he faces Marik who uses the "The Winged Dragon of Ra" as final opponent.
On a replay game, it is possible to face him as Nitemare, whose God card will have maxed-out stats.
