Duel Academy's students arrive at Domino City for their field trip. Jaden Yuki, Syrus Truesdale and Tyranno Hassleberry purchase guidebooks to visit the city's landmarks. They visit the pier where Yugi Muto Dueled Joey Wheeler, while the latter was controlled by Marik Ishtar's Millennium Rod. They later arrive at Solomon Muto's Kame Game shop. They introduce themselves to Solomon, and upon explaining that they are from Duel Academy, he allows them to come inside, explaining that Yugi is probably off on another journey (in the dub, he says that Yugi "went to the market to get some olives three years ago"). He offers to be their tour guide for the rest of the day, and he takes them to the sites where Yugi Dueled Seeker and Strings. He lags behind as they continue to their next destination, and is kidnapped. They split up to search for him, and run into Chazz Princeton. He tells Syrus and Hassleberry that they are to meet the kidnappers on the roof of a building - the same building on which Yugi and Seto Kaiba once Dueled Umbra and Lumis.
They do so, and are met by the kidnappers - Frost and Thunder. They are to Tag Duel them. Frost plays "Side Attack", which essentially changes the format of the Tag Duel to that of two single Duels - Syrus and Thunder may not attack Hassleberry and Frost, and vice-versa. Frost and Thunder Summon "Ice Knight" and "Thunder Knight", respectively, and Tribute them to Summon the "Monarch" monsters of the same Attribute - "Mobius the Frost Monarch" and "Zaborg the Thunder Monarch". They also play a combination of "Reflector Bit" monsters, which lets them reflect damage to their oppnents. Hassleberry is reduced to 1100 Life Points before Syrus' second turn comes.
Tributes "Ice Knight" to Summon "Mobius the Frost Monarch" (2400/1000) in Attack Position. Its effect activates, destroying "Jurassic World" and Hassleberry's Set card.
Activates Continuous Spell Card "Mobius Castle", decreasing the ATK and DEF of all Dinosaur, Winged Beast, Plant, Beast and Beast-Warrior-Type monsters that his opponents control by 500. "Dark Driceratops" loses 500 ATK and DEF (1900/1000).
Attacks and destroys "Dark Driceratops" (Hassleberry 4000 → 3500).
Summons "Archeonis" (300/1300) in Attack Position.
Activates "New Ultra Evolution", Tributing "Archenois" to Summon "Dark Tyranno" (2600/1300) in Attack Position, whose attack points decrease by 500 due to "Mobius Castle".
Attacks, but Frost activate his face-down "Bit Shoot", Special Summoning "Reflector Bit" (0/0) from his Deck, which redirects target of the Battle damage to Thunder, who activates his own face-down "Bit Shoot" to Summon a "Reflector Bit" (0/0) and activates its other effect. Should he take damage from Frost's "Reflector Bit", he can inflict 500 damage to Syrus (Syrus 4000 → 3500).
In the English version, the guidebook that Hassleberry reads from incorrectly states that Pegasus handcuffed Yugi and Joey for their Duel at Domino Pier. Syrus corrects him on this. This is not present in the Japanese version, as both had the same guidebook, which was said to have been written by Solomon Muto. Solomon's own depiction in the English version was of a senile old man, while in the Japanese version, he appeared just as he did in the previous series.
