Changes
During this time, Jaden and the Academy return to the dimension to search for Jesse and arrive in a different section of the dimension. While Jaden and the students battle the members of a Duel Monster empire, Jesse is possessed by [[Yubel]]. Intending to use Jesse as an avatar through which to secure the dimension in preparation for an evolution to a more powerful form, [[Yubel]] is opposed by Adrian Gecko, who challenges him for dominance even as Jaden rushes to challenge [[Yubel]] himself. Although [[Yubel]] was weakened a duel with Zane it had just previously had, it still beat Adrian, and recovered its strength in the process. However, when Jaden finally duels [[Yubel]] to save Jesse, it is revealed that Yubel actually removed Jesse's soul from his body and placed him inside the Rainbow Dragon before taking over. Although Jaden manages to free Jesse, [[Yubel]] escapes and duels Jaden herself.
As Jaden and [[Yubel]] dueled, Syrus, showing how much of a true friend to Jaden, follows suit after the two and on the way Syrus ends up talking to [[Chazz Princeton]], who was supposedly 'killed' along with Alexis, [[Tyranno Hassleberry]] and Atticus. Chazz tells Syrus that when they disappeared in front of Jadens eyes during a duel against Brron, the king of the dark world, they weren't killed. But transported to alternative dimensions. The same thing had happened to Axel, Jim (who lost their the duels against Jaden possessed by [[The Supreme King]]), [[Aster Phoenix]] (who lost his duel against Adrian Gecko) and [[Zane Truesdale]] (who lost his rematch against Jesse when he was possessed by Yubel).
During the final duel between [[Yubel]] and Jaden, Jaden understands that [[Yubel]] was a guardian spirit of Jaden when Jaden was apparently a prince of a kingdom. Yubel deciding to be the guardian of him transforms herself into the form that Jaden and the others see now. Syrus, who was watching the duel at the time, saw Jaden and Yubel disappear into what was the center of the 12 dimensions. But before Jaden disappeared, Jaden did his signature pose and promised that he would finish the duel and return when he 'became a man'. In the center of the dimensions [[Yubel]] activates a trap card that would allow her to destroy all the dimensions at once and Jaden at the same time. But Jaden, after realising that [[Yubel]] was doing all this to protect him, uses Super Fusion to fuse not the monsters that Jaden and [[Yubel]] had on the field, but to fuse Jaden and Yubel souls together in order to 'become one'. The duel supposedly ended in a draw and after this, most of the students who accompanies Jaden to the other dimension arrive back in the real world. Zane, Adrian, Bastion and Jaden didn't return when the gang came back and are presumed 'missing'. However, prior to Jaden's duel with Yubel, Bastion decides to stay in the alternate dimension with Tania and her friends.
