The Curtain Rises for Battle! The Return of Son Goku

The series begins with a flashback where Bardock's failed to prevent the destruction of Planet Vegeta at the hands of Frieza, and the upbringing of Bardock's son Goku on Earth as depicted in the original Dragon Ball series. Five years have passed since Goku's victory over Piccolo at the 23rd World Martial Arts Tournament, and he has since married Chi-Chi and now has a son named Gohan. Goku and Gohan are heading towards a reunion with Goku's friends at Master Roshi's island. Elsewhere, an odd-looking spacecraft crash lands on Earth. A man in battle armor emerges from the vessel and flies off to scout out a powerful life form he locates with the help of an apparatus on his eye. Piccolo is nearly killed by the stranger, but this is averted when the man leaves to scout out a more powerful life form. The other strong life form is Goku, who at the Kame House presents his son to Roshi, Krillin, and Bulma. The stranger arrives and surprises everyone when they notice he has a monkey-like tail, just like Goku used to have.
