Neo Space is a Duel Monsters Spirit World appearing in Yu-Gi-Oh! GX. It is introduced in the second season as a part of the universe inhabited by the Neo-Spacians, part of which orbits around Jupiter. Jaden Yuki was transported to Dolphina, a planet inhabited by dolphin-like creatures, such as Aqua Dolphin. There Aquos make him familiar with the battle between the light and the darkness, good and evil, and the upcoming threat, the Light of Destruction. Aquos also explained him that he is destined to fight the Light, as he wields the power of Darkness of Justice. At that time, Neo Space was invaded by a Dueling machine, an emissary of the Light. Jaden found Duel Monsters cards in a crushed KaibaCorp satellite, which he designed as a child, including "Neos", "Neo-Spacians" and "Chrysalis". U
