Yu-Gi-Oh! GX: A Greater Porpoise

Overview

A disappointed Jaden wanders around outer space. It's weird, but with a friendly dolphin-shaped space alien's guidance, Jaden is reunited with an illustrated card he drew in his childhood, which Kaiba Corp. launched into space. But, that card became perfect by evolving through the power of space's intention. Jaden duels a hostile alien life form. At the end of the universe, the energy form obtains the power of Neo Space, and Jaden starts to understand a new deck concept that gives his monsters a power up.
