[first lines of season 2]
Narrator: For one year now, Earth has been at peace. The Gamilons no longer threaten the galaxy. But unknown to Earth, a new danger lurks in the darkness of outer space: a seemingly harmless great white comet streaks across the sky, a comet so deadly that it threatens the universe, as it conquers and devours every sattelite and every planet it approaches. But it is not a natural comet. It's the Comet Empire - a huge, complex construction, made to resemble a comet. This evil empire has launched a campaign to conquer space. Planets of no value to its monstrous plan - it destroys. Those with resources and population it can exploit - it ruthlessly takes over. Now the Comet Empire is reaching out for Earth, a planet once again beautiful and thriving, after recovering from a deadly radioactivity caused by Gamilon's planet bombs. In the palace of the Comet Empire, evil Prince Zordar and Princess Invidia look down on Earth with greedy eyes.
