Two years after the defeat of Majin Buu in the main Dragon Ball series, Mr. Satan finally finishes construction on his brand new hotel. Feeling guilty that the hotel is in honor of what the majority of Earth believes to be his defeat of Buu, he invites all of the Z Fighters and their families to a banquet. Shortly after dinner two Saiyan Spaceships land just outside of town, and a mysterious Saiyan and his wife confront the Z-Fighters at the hotel. They are revealed to be Vegeta's younger brother, Tarble, who had been deemed too weak to fight in the past and thus had been sent to a distant star before the destruction of Planet Vegeta, and his wife Gure. He asks his brother for help in dealing with Abo and Cado, soldiers who are remnants of Freeza's army (who were ranked with the Ginyu Force), who are causing havoc on his planet.
