Ep 16. On the Wrong Track, Part 1

Yugi and his friends are on their way to the Battle City Finals when they are suddenly derailed by a subway car that has mysteriously gone off-track. As they investigate the scene, it becomes clear that this is no ordinary subway accident. The tracks have been tampered with, and the culprit is still at large.

As Yugi and his friends search for clues, they come across a group of suspicious individuals who seem to be involved in the incident. One of them, a man named Zigfried, claims to be the president of a large corporation that is responsible for the maintenance of the subway system. However, Yugi and his friends remain skeptical of his true intentions.

Despite their reservations, Yugi and his friends are determined to find out what really happened to the subway car. They follow a trail of clues that leads them to an underground laboratory, where they discover a shocking truth: the accident was not an accident at all, but rather a deliberate act of sabotage.

With this new knowledge, Yugi and his friends must race against time to stop the mastermind behind the attack before they can strike again. But they soon realize that this will be no easy task, as the villain is more cunning and dangerous than they ever could have imagined.

As the stakes continue to rise, Yugi and his friends must use all of their skills and resources to navigate the dangerous territory of the underground laboratory and defeat the enemy once and for all. Will they be able to uncover the truth and save the day, or will they be derailed by the forces of evil? Only time will tell in this thrilling episode of Yu-Gi-Oh! season 4.
