Synopsis by Hal Erickson
Unaware that Captain Ginyu has taken over the body of Goku, a reluctant Gohan prepares to do battle against his own father. Meanwhile, Vegeta displays a hitherto unseen and unsuspected show of strength. As "Gohan Defeat Your Dad" draws to a close, the horrible possibility exists that Vegeta has become a Super Saiyan -- just like Goku. This sixth episode of Dragon Ball Z's "Captain Ginyu Saga" first aired in Japan on January 9 1991, and in America on September 17 1999.
