The Three-Star Dragon

Goku and Nova, the four-star dragon, begin to fight. Goku catches Nova off guard but doesn't finish him off, because Nova released Pan at Goku's request. Nova says that he doesn't harm innocent and helpless people. As they continue to fight, a beam comes out of nowhere and hits Goku's arm, freezing it. It came from Ice, the three-star dragon. Nova reveals that Ice is his brother. Ice has taken the Dragon Balls from Pan, and he gives them to Nova. He then freezes the rest of Goku. Ice commands Nova to finish Goku off, but Nova refuses because Goku can't defend himself. Ice beats up Nova, and reissues his command. Nova appears to obey, but his attack just melts the ice. Goku thanks Nova, and promises to beat Ice in ten seconds.
