King Kai senses the destruction of the south galaxy by a Super Saiyan and realizes that the north galaxy will be targeted next. He
telepathically contacts
Goku, who begins tracking the Super Saiyan's energy. On Earth, a spaceship interrupts a picnic, and an army of
humanoid alien soldiers greet
Vegeta. Their leader is revealed to be a Saiyan named Paragus who claims that he has created a new Saiyan planet and wishes for Vegeta to assume the throne. Vegeta agrees after Paragus tells him that the "Legendary Super Saiyan" is running rampant throughout the galaxy and must be stopped.
Gohan,
Future Trunks,
Krillin,
Master Roshi and
Oolong accompany Vegeta onto the ship. On New Vegeta, Vegeta meets Paragus's son,
Broly, who joins him in tracking the Super Saiyan. Gohan, Trunks, and Krillin explore New Vegeta and discover that it is uninhabited except for alien slaves who reveal that a Super Saiyan destroyed their civilization. The masters begin to abuse them, but are fended off by Gohan and Krillin. Goku arrives and is greeted by Paragus, who recognizes him as Bardock's son and invites them to dinner at the palace. Broly is agitated at the mere sight and presence of Goku. Paragus controls his son by using a device on his bracelet that syncs to Broly's headband. Despite this, Broly attacks Goku at night, requiring Paragus to calm him. Goku suspects that Broly is the Super Saiyan, and Paragus contemplates the mind-control device and suspects that it is malfunctioning due to Broly responding aggressively to Goku. Paragus theorizes that Broly's violent Saiyan instincts are awakening due to Goku's power, then remembers they were born on the same day in an attempt to explain their fated encounter after all these years. Goku and the others confront Paragus upon learning the truth about Broly as his aggression toward Goku swells. Broly breaks free of the mind control device and transforms into the Legendary Super Saiyan. Broly attacks Goku, who Trunks and Gohan defend, while a fearful Vegeta loses his will to fight before the Legendary Super Saiyan. Paragus taunts Vegeta while revealing that Broly was born with a power level of 10,000 and was feared by King Vegeta, who ordered Broly's execution. Paragus failed to persuade King Vegeta to spare Broly's life, who was pierced in the abdomen by a knife and left for dead with his father. At the same time,
Frieza destroyed the planet that same day, where Bardock tries to defeat him unsuccessfully. Broly's survival instincts caused him to shield himself and Paragus, and they soared off into space protected by Broly's power. Broly grew unstable and sadistic as he aged. Paragus was forced to use a mind-control device to pacify his son, but planned to use him to exact his revenge on King Vegeta's bloodline and convert the Earth into New Planet Vegeta. Paragus reveals that a
comet is approaching New Vegeta and will destroy it upon impact. Goku, Gohan, and Trunks are dominated by Broly until
Piccolo arrives and heals them with Senzu Beans. They engage Broly again, but continue to be severely outmatched. After being scolded by Piccolo, Vegeta's pride finally returns, and he confronts Broly, but is quickly incapacitated. Paragus prepares to escape the doomed planet in a small space pod before he is confronted and killed by Broly. Despite Broly's power continuing to increase, Goku manages to challenge him yet again, and he is mercilessly beaten as he asks his allies to lend him their
ki. After much reluctance, Vegeta, despite his pride, finally gives his ki to Goku, who uses it to strike a piercing blow into Broly, causing the Legendary Super Saiyan's power to become unstable, and he explodes. Just as the comet strikes and destroys New Vegeta, Goku, his allies, and the slaves cheer as they escape in Piccolo's spaceship to return to Earth. ==Cast==
