Synopsis
In a robot-populated universe, the Rainbow Planet consists of seven nations, each representing a different color of the rainbow. A protective dome shields this world from external threats. Meanwhile, the Dark Planet, ruled by the Black Hole King, seeks out and absorbs other planets for their energy. When the Dark Planet discovers the Rainbow Planet, it attempts to consume it, but the dome prevents this. However, the ongoing war among the seven nations on the Rainbow Planet gradually weakens the dome's defenses. Seizing this opportunity, Prince Zebra is sent from the Dark Planet to escalate the conflict. Amid the chaos, Fredo, a young man with immense powers, rises with the mission of bringing peace to the nations and uniting them against the Dark Planet's menace.
