Le feu et la glace

Goku and Nuova, the four-star dragon, begin to fight in earnest. Goku catches Nuova off guard, but grants him a freebie because Nuova spared Pan's life at Goku's request when he could have easily destroyed her. Nuova 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 Eis Shenron, the three-star dragon, and Nuova's twin brother, who was (as revealed in Dragon Ball GT Perfect Files) brought forth by the wish that erased the memories of Majin Buu from everyone on Earth excluding the Z Fighters and their friends. Eis has taken the Dragon Balls from Pan, and he gives them to Nuova. He then freezes the rest of Goku. Eis commands Nova to finish Goku off, but Nuova refuses because Goku can't defend himself. Eis beats up Nuova, and reissues his command. Nuova appears to obey, but his attack just melts the ice. Goku thanks Nuova, and promises to beat Eis in ten seconds. (Source: Wikipedia)
