It was a beautiful day in the Land of Light. Everyone was enjoying the view. However, deep in space, Zagian Energy began to flow to a single spot, like a vortex: The Power Core of Dark Zagi. When all the Zagian Energy finished flowing, Dark Zagi revived. He stood up, and muttered, "Traitor to my empire, traitor to me! I will eliminate and completely destroy you, my son, Dark Kogaxion!" With that, he set off for the planet Arb, where Dark Kogaxion was currently stationed.
Dark Kogaxion was having a beautiful day on the Planet Arb. Before going to station there, Ultraman Hikari told him all about Arb and the mysterious crystalline life forms that inhabited it. So far, he was enjoying talking to those crystalline life forms that Hikari was talking about. Suddenly, he saw a dark cloud approach from the horizon, and he instantly knew who it was: his father. He prepared to battle with Dark Zagi and to defend the planet Arb at all costs. He got into his battle stance and was preparing a Morium Cross Shoot. He then shot at the dark
cloud that Dark Zagi was in. However, the cloud easily dodged the shoot, and all Morium Cross Shoots after it. Dark Kogaxion thought his father would land, so he was preparing a forbidden burst. However, the cloud directly seeped into his heart. Instantly, he felt his body taken control of. He tried to resist, but Dark Zagi's rage held much more power. With that, Dark Kogaxion became a shell, a powerful shell, in Dark Zagi inhabited.
