ドラゴンボールZ この世で一番強いヤツ

Dr. Kochin gathers the Dragon Balls and wishes his mentor Dr. Wheelo's buried laboratory free of the ice that swallowed it decades ago. Wheelo survives as a brain in a tank and wants the body of Earth's strongest fighter. His bio-warriors seize Bulma and force Master Roshi, whom Wheelo still takes for the world's strongest, to come along. Goku follows them to the frozen mountain fortress, with Gohan and Krillin close behind. This is the second Dragon Ball Z feature film.
