Dragon Ball Z Kai: Full Story Recap (Season 1–5) Kai

The story begins with Goku living peacefully on Earth with his son, Gohan. Things quickly change when a mysterious warrior named Raditz appears, revealing himself as Goku’s brother and exposing Goku’s alien origins—he is a Saiyan from the planet Vegeta. Raditz’s plan to recruit Goku fails, and a fierce battle follows. Goku sacrifices himself to defeat Raditz with the help of his former enemy, Piccolo. After this, Earth is threatened by two more powerful Saiyans: Vegeta and Nappa. As Goku trains in the afterlife, the rest of the Z Fighters prepare for battle. Nappa kills several of Goku’s allies before Goku returns to face him. Eventually, Goku has a climactic fight with Vegeta, which ends with Vegeta retreating in defeat.
