Okay, here is an English introduction to the storyline background of Dragon Ball Z (恐龙快打):
Dragon Ball Z: Story Background
Dragon Ball Z (often abbreviated as DBZ) is the direct sequel to the original Dragon Ball series and serves as the primary continuation of its narrative. While the original focused more on childhood adventures and martial arts training leading up to the Red Ribbon Army arc, Dragon Ball Z shifts the focus to a more mature and darkly toned exploration of power, conflict, and the consequences of martial prowess.
The story picks up several years after the defeat of the Red Ribbon Army, with the main characters – Goku, Chi-Chi, Piccolo, Gohan, and Krillin – having grown older. Goku, now a young adult, has become the acknowledged strongest warrior on Earth.
The Frieza Saga (Episodes 1-113):
The primary driving force behind the early DBZ series is the introduction of the powerful and ruthless alien Frieza. Once the ruler of the Universe 7 Saiyan Empire, Frieza has conquered numerous planets and is feared throughout the universe. However, he holds a deep, personal vendetta against the Saiyans, particularly the ones who once served him – Goku and his brother Raditz.
Frieza discovers that Goku is a Saiyan, the very race he despises and seeks to eradicate. He arrives on Earth to destroy it, believing the Saiyan is weak and represents a threat to his rule. This leads to the climactic battle between Goku and Raditz, during which Goku first learns of his true origin as a Saiyan prince sent to Earth to conquer it, and the tragic truth about his father. Frieza then destroys Planet Vegeta, home to most Saiyans, and leaves Goku to die, setting the stage for an epic revenge saga.
The story then follows Goku's intense training under Master Roshi and King Kai in the afterlife to prepare for his eventual confrontation with Frieza. Meanwhile, Frieza continues his campaign of destruction, eventually reaching Earth and battling Goku, Piccolo, Gohan, Krillin, and the newly arrived Androids 18 and 19. This culminates in the introduction of the legendary Super Saiyan transformation, achieved by Goku during his desperate battle against Frieza, marking a major turning point in the series.
The saga continues with the search for the Dragon Balls to wish back the dead Saiyans, culminating in Frieza's defeat and subsequent revival as a Super Saiyan by his underling, Vegeta, leading to the powerful Majin Buu.
The Buu Saga (Episodes 114-288):
Following Frieza's defeat, the Earth briefly enjoys peace. However, this is shattered by the appearance of a mysterious and incredibly powerful entity known as Majin Buu. Buu absorbs several powerful characters throughout the universe, including Fat Buu absorbing Goku, Vegeta, Gohan, Piccolo, and Gotenks, ultimately fusing into Super Buu.
This final saga involves an extensive cast of characters from across the universe teaming up to fight Buu. Goku, Vegeta, Gohan, Piccolo, and Krillin are among the primary fighters. The story features numerous transformations and power-ups, including Gotenks and Piccolo fusing into Piccolo Gotenks, and Goku and Vegeta fusing into the incredibly powerful Super Saiyan 3 Gotenks. Eventually, Goku fuses with his son Gohan to become the even stronger Super Saiyan 3 Goku.
The ultimate solution comes from the Z Fighters' mentor, Grand Elder Kai, who transports Goku to another dimension where he trains for a year, mastering the technique of Spirit Bomb. Goku returns, defeats Super Buu, and, in a final act of mercy ordered by Vegeta, vaporizes Buu with a Genki Dama (Energy Ball of Life).
Overall:
Dragon Ball Z is primarily defined by its escalating interplanetary and universal conflicts, the pursuit of immense power, and the evolution of its core cast as they face increasingly powerful enemies. It explores themes of good versus evil, the burden of power, the importance of friendship and family, and the relentless drive to become the strongest.
