S03E51 - Le retour de l'ultime souverain (3)
Synopsis
Jaden utilizes the "Crystal Beast" cards he was entrusted by Jesse to summon "Rainbow Neos," equipping it with "Rainbow Veil" and launching an attack on Yubel. In turn, Yubel transforms into her second form, activates Demon's Rose, and fends off the damage. In the end, Jaden uses Super Polymerization to fuse his spirit with Yubel. He saves his friends and they go back to their dimension, but Jaden doesn't come back. The episode ends with Hassleberry asking where the Sarge was and Syrus replying,"He's in the stars."
Note: Along with Jaden, Zane, Bastion and Adrian didn't come back to their dimension either.
