Yu-Gi-Oh! Worldwide Edition: Stairway to the Destined Duel

This game takes place in Battle City.

Start of Game Duelists

• Mokuba Kaiba: The easiest duelist in any Yu-Gi-Oh! game. His strongest card is Kanan the Swordmistress and the only trap card he uses is Magic Jammer. Occasionally, when you challenge Mokuba, Kaiba will intercept and you will duel him instead. He does not play monsters in defense mode, making him always wide open for an attack. Also, sometimes he has a Cyber-Stein and a Blue-Eyes Ultimate Dragon and may use them as a combo.
• Tea Gardner: She runs a deck filled with female cards such as Fire Princess, Marie the Fallen One, Sonic Maid, and Lady Assailant of Flames. She'll also pull out fusion monsters like Mystical Sand and Warrior of Tradition from time to time.
• Joey Wheeler: Joey runs a lot of luck-based cards like Skull Dice, Graceful Dice, and Time Wizard.
• Yugi Motou: Yugi mainly runs Magnet Warriors and Spellcasters. He is one of the hardest opponents in the game.
• Seto Kaiba: Seto Kaiba is also a hard duelist. He tries to acquire tributes for his Blue-Eyes White Dragon and if given the opportunity he will use the effect of Cyber-Stein to summon his Blue-Eyes Ultimate Dragon.
• Mai Valentine: Mai runs a general Winged Beast-Type / Wind-Attribute deck with Harpies as her centerpiece. Be careful if you run Cyber Harpie because she can use your own Harpie to activate Elegant Egotist to summon Harpie Lady Sisters.
• Mako Tsunami: Mako Tsunami runs water monsters and the Field Spell Card Umi. He can often pull off an annoying combo of Umi and Tornado Wall that prevents him from taking any Battle Damage.
• Espa Roba: Espa Roba uses a loose "psychic"-themed deck with cards that can allow him to "see" your deck such as Big Eye and Light of Intervention. His most powerful monster is Jinzo.
• Weevil Underwood: Weevil uses Insects, and his goal is usually to bring out his Insect Queen. He also uses many Flip Effect monsters such as Needle Worm, Parasite Paracide, and Man-Eater Bug
• Rex Raptor: Rex Raptor uses Dinosaurs such as Two-Headed King Rex.
• Solomon Muto: Solomon doesn’t quite have a theme however, he does have an Exodia set in his deck.
• Ryo Bakura: He mostly uses the Destiny Board cards and Gravekeeper's Servant.
• Ishizu Ishtar: Her deck is filled with rather powerful Light-Attribute / Fairy-Type monsters such as Hysteric Fairy, Dunames Dark Witch, and The Forgiving Maiden. Some of her other cards include Luminous Spark, Soul of Purity and Light, and St. Joan.

Late Game Duelists

• Marik Ishtar: Dark Monsters leveled with Gravity Bind.
• Bandit Keith: Gamble Cards and Machines
• Duke Devlin: Dice Cards
• Maximillion Pegasus: Pegasus runs a deck filled with Toons
• Rare Hunters: If you lose to them, they will steal your cards. In the early game they are encountered randomly when you talk to passengers, but later you can unlock them as regular opponents.
  • Exodia Rare Hunter: Exodia
  • Strings: Revival Jam
  • Lumis and Umbra: Masks
  • Arkana: Dark Magician
  • Odion: Lots and lots of Trap Cards
• Shadi: He will copy the deck of one of the other opponents in the game (for example Yugi, Kaiba, and Marik).

Glitches

• Bandit Keith, has an unplayable card in his deck; a level 1 monster with 0 ATK/DEF and no card art. This card disappears from his hand after it is drawn.
  • Sometimes the screen will randomly go to a screen where Keith declares the duel a draw.
  • When he activates "Gamble", and calls it wrong, you better hope to finish him off that turn, or stop his card with anything you have, because when the game tries to go to his turn, it skips it, which ends the duel, (which it shouldn't, as it should let you start another turn) resulting in a DRAW.

• If you have already begun to have the random announcements proclaiming that rare hunters are on the loose and enter one of the tournaments there is a chance that Marik will show up as your random opponent, even if you haven't faced him in the normal storyline.

• Fighting Espa Roba the day before a Challenge Cup makes it not happen, for some reason.

• If you press any button when you or your opponent uses Graceful Dice or Skull Dice, the game will freeze. Normally you can get by this by pressing the A button to skip the cut scene sequence that freezes the game.

• If you use Premature Burial on Sangan, and then use Dark Hole, you'll be able to use Sangan's effect twice instead of once

• If you don't like your target week targets press START to bring up the language menu. Then leave the language alone and press B the guy will announce target week again and give you two new targets.

• Try reviving The Immortal of Thunder face down with Spear Cretins effect,

if your opponent attacks and kills it you get 3000 LP for the flip effect and they lose 5000 LP when the copy of Immortal is put in their graveyard. (Spear Cretin just creates copies of cards from the graveyards that, once destroyed, end up in the wrong graveyard)

• Use Polymerization on a Witch of the Black Forest on the field along with a fusion substitute monster to fuse them into Musician King and trigger the effect of the Witch twice.

• Use Change of Heart twice in one turn, on 2 different monsters that are next to each other. When you end your turn, the first card will return normally, but when the second returns it overlaps the first, never to be seen again anywhere that duel.

• Normally Hourglass of Courage has to be face-up on the field for 3 full turns for its double ATK/DEF effect to work, but if you use Call of the Haunted to revive it during your opponent's turn, its effect is applied on your next turn, even though this is only the second turn.

• If you have Exodia the Forbidden One or any other Exodia piece on the field and the other pieces in your hand, it is declared a tie.

• The spell card Makiu had the following lore: Select either "Left Arm of the Forbidden One" or any Thunder-Type monster. Destroy all opponent's monsters whose DEF is lower than the ATK of the selected card. During this turn, you cannot conduct your Battle Phase.
