Darkness (Duel World)
The World of Darkness, known as the Jet-Black World (漆黒の世界, Shikkoku no sekai) in the Japanese version, is the fourth Duel World in Yu-Gi-Oh! World Championship 2008.
This world introduces the player to Tag Duels, and entering it for the first time adds Tag Duel Mode to World Championship Mode.
Neo-Spacian Dark Panther will explain the mechanics of Tag Duel to the player and also puts the player in a practice Duel to demonstrate. After this, he'll become the player's default tag partner. Most Single Duel opponents can be unlocked as Tag Partners for the player by defeating them 10 times. Any Duel Ghost the player may have downloaded can also be partnered with.
Ocassionally, the player can find Nurse Reficule the Fallen One, and she may randomly change the appearance of the player's face for 500 DP. The player cannot change the result, but the game does not save automatically after having their face changed, so players can reset the game to get their previous face back if they do not like the result.
Duel Spirits teams[edit]
Now, this place has several teams waiting for the player. Defeating each of them 5 times will unlock the respective team in World Championship Mode.
- Mythical Beast Cerberus and Darkblaze Dragon (unlocks Decoy Dragon and Different Dimension Dragon)
- Goe Goe the Gallant Ninja and Lady Ninja Yae (unlocks Sasuke Samurai and Sasuke Samurai #2)
- Vanity's Fiend and Vanity's Ruler (unlocks Machine King and Perfect Machine King)
- Dark Mimic LV3 (gets the player in a 1v1 Duel against it; unlocks nothing)
Once in a while, there will be a treasure chest around the area. The treasure chest can either contain nothing, DP, card, or be a Dark Mimic LV3 that will duel the player in a one-on-one Duel.
There's Renge, Gatekeeper of Dark World waiting at a corner. The player can talk to him, and each time the player does so, the player will find themselves in a Tag Duel with some Dark World denizens. The player will also have to ante a card with "Dark World" in its name in order to begin these duels. The teams are:
- Kahkki, Guerilla of Dark World and Zure, Knight of Dark World
- Goldd, Wu-Lord of Dark World and Sillva, Warlord of Dark World
- Brron, Mad King of Dark World and Reign-Beaux, Overlord of Dark World (defeating this team unlocks themselves in Tag Duel mode)
Also, since the player is wagering a card, the player will also get a Dark World card each time the player defeats a team.
Once the player beats all three Dark World teams, the three teams that normally appear in the area will be stated to be brainwashed. The player has to defeat each team to return them to normal, and then a castle will appear.
Castle[edit]
The player will be greeted by Gogiga Gagagigo and Mobius the Frost Monarch. The player has to defeat them, and they will afterwards be challenged by Vampire Lord and Vampire Lady. Defeat both teams and they unlock themselves in World Championship Mode.
Alien Infiltrator arrives, grumbling about the player undoing the brainwashing, and disappears into the sky.
Sky[edit]
The map has expanded - the player heads up into the skies and takes on more teams.
- Harpie Queen and Harpie Girl (unlocks Harpie Lady 1 and Harpie Lady 2)
- Metal Shooter and Satellite Cannon (unlocks Adhesive Explosive and Blast Sphere)
- Lich Lord, King of the Underworld and Alien Hypno (unlocks Alien Mars and Alien Psychic)
UFOroid also appears on occasion. Correctly guess the symbol it is thinking of, and it will give the player a "Roid" card.
After beating each team once, Alien Infiltrator and Alien Shocktrooper will challenge the player to a brainwashing Duel - this one is computer-controlled. After the player beats them, they unlock themselves in World Championship Mode, and reveal the gate to the next world.
Gate[edit]
When the player goes to the next gate, the player is to face the guardians, Dark World Guardian - Gigori and Underworld Guardian - Moley, and their five Deck combinations. The player needs to beat three to proceed to the World of Order, and beating all five unlocks Aster Phoenix in World Championship Mode.
Stone Monument[edit]
The Stone Monument will appear once the player has defeated every team five times each. The stone monument has a carving of Vennominaga the Deity of Poisonous Snakes. The player needs to summon Vennominaga and use its effect to win the Duel in order to unseal it. Beating the monument will unlock Professor Thelonious Viper in World Championship Mode.
