Return of Freeza/ Battle of the Mysterious Youth... A spaceship passes by what used to be Namek. Its leader, Cold, is the father of Freeza. He finds the remains of his son's body flowing through space. Cold's henchmen are sent to rescue Freeza. Freeza is literally rebuilt and becomes half robotic. Freeza tells his father to set a new course to Earth. Cold still laughs at how anyone could have defeated a member of his family, the strongest in the universe. Now, father and son head to Earth for revenge of what happened. Planet Namek has been restored. The Z Warriors, also all revived now, prepare for the coming of Freeza along with the aditional threat of Kind Cold. Without Gokou's help, they can only watch the spaceship land. Cold and Freeza believe in a swift victory in desroying Earth, but a teenager appears out of nowhere. The mysterious boy easily uses a sword to cut up Cold's henchmen. Then, he powers up and boasts that Gokou is not the only Super Saiyan. Vegeta recognizes the aura of the man to be that of a Saiyan, and resents the fact that there is another stronger than him. Freeza creates a fireball 10x the size as the one he used to destroy Namek and launches it at the boy. The teen easily catches the fireball with one hand and shatters the ball. Then, he takes out his sword again and slices Freeza to bits before blowing the body parts away with a single blast. Cold, supposedly much stronger than Freeza, goes to battle the stranger but also gets quickly killed with a blast from the boy. The stranger flies to the Z Warriors and tells that Gokou will be back in exactly 3 hours at a location not too far away. The Z cast follow the teen and wait. The boy refuses to tell anything, except for his age. In three hours, Gokou really does land on Earth on a spacepod. More startling, Gokou has never seen the teen before. The boy tells Gokou to talk to him alone. The stranger introduces himself as Trunks. His story is told in Trunks Story. He tells that he is the only surviving warrior in a future 20 years from now. He traveled back in time to alter to past so that his ruined time would change. Trunks mentions that in exactly three years, two super strong beings will appear. These beings are cyborgs of Dr. Gero, the scientist of Red Ribbon who was thought to be dead. They will kill everyone (including their creator Dr. Gero and live only to destroy, recking everything in path for no reason). Trunks also tells that Gokou will develop a heart disease and die from it. The disease is incurable now, not curable by Trunks' timeline. Trunks hands Gokou the heart disease medicine and tells him to prepare for the future. Trunks also slips out that he is the son of Vegeta and Bulma. (Bulma and Yamcha broke up and Bulma felt sorry for Vegeta's loneliness. They fell in love and Trunks was to be born in two years.) Trunks tells that he will be back in three years and flies off in his time machine. Gokou returns to his friends on the other side of a cliff. Gokou tells how he survived Namek. When Namek prepared to explode, Gokou entered Freeza's spaceship, but the ship didn't work. One of the Ginew Force's ship was nearby and Gokou rode in it. He crashed in a nearby planet, Yardat, where the Yardatrians (purple aliens who look like a blend of  the Jedi-Master of Star Wars and the Brain of Pinky and the Brain) taught him how to teleport. Then, Gokou traveled back to Earth. Piccolo then tells that Nameks have better hearing than Earthlings and Saiyans, and that he overheard the entire conversation between Gokou and Trunks. Piccolo tells everyone of Trunks' news. The Z Warriors prepare training for the coming of the next three years, the Cell Series...
