"Let the Finals Begin!", known as "Battle Ship Takes Off!" in the Japanese version, is the eighty-first episode of the Yu-Gi-Oh! anime. It first aired in Japan on November 13, 2001, and in the US on August 30, 2003.
Seto Kaiba is waiting with his brother Mokuba for the Battle City finalists to arrive. The first three finalists, Yugi, Joey and Mai arrive with their friends (Tristan, Serenity, Téa and Duke). Marik Ishtar, the next finalist, arrives but is still using his disguise of Namu. Joey is suspicious about his true motives, but eventually dismisses it. Bakura arrives even though he is still injured and announces he is also a finalist, baffling everyone. Odion Ishtar comes in at this point, creating a commotion as Yugi, Kaiba and Joey recognize him as Marik, and Odion continues to identify himself as Marik and another finalist.
Mokuba introduces Kaiba Craft 3, a huge airship where the finals will take place. The airship lands and all the contestants enter, although Yugi's friends are initially not allowed as they are not finalists but Mokuba persuades Kaiba to let them on. Kaiba orders the airship to leave, even though the remaining finalist has not arrived but at the last minute Ishizu Ishtar enters with a mask over her face to conceal her identity. Since she is the finalist, the Battle Ship can take off without delay.
The finalists spend time alone in their designated rooms, except for Joey who is with Serenity and later Tristan, Téa and Duke, who do not have their own rooms. Yugi plans his deck while talking to Yami Yugi and they agree that Bakura is once again under the influence of the Millennium Ring. The finalists are called to the main hall to decide who will duel first.
Differences in adaptations
A scene of Yami Bakura violently eating steak and saying "Not enough blood." is removed from the dub.
When Yugi, Joey, and Mai are asked to show their six locator cards, all three show seven cards instead of six.
After Bakura reveals he is a finalist, the scene of Marik (still in the guise of Namu) shows him without a Duel Disk.
When Roland and Isono announce that the actual location is on a blimp, Marik is still seen without a Duel Disk, and Kaiba mistakenly has his on his right arm, but then it switches back to his left arm, like everyone else's shown.
The two men asking to see the locator cards are Isono and Roland, but they are switched after this episode. Mokuba calls the second man at the blimp Roland, but later the first man is called Roland, who is the referee.
The following cards appeared in this episode.
