Trunks, Gohan, Master Roshi join Vegeta aboard the ship. Goku instant transmissions to the South Galaxy in search of the Legendary Super Saiyan. Once on New Planet Vegeta we are introduced to Paragus's sun Broly. The Super Saiyan was cited on Planet Totachoma and Vegeta heads off to find him. Trunks, Gohan, and Krillin discover that the New Planet Vegeta is no more than ruins that looked like cities from space. Before you can blink Gohan, Krillin, and Trunks are causing trouble. As Krillin shows off Goku materializes in the path of one of Krillin's punches. Comet Kamoru is on a collision course for Planet Vegeta and Paragus is deviously happy. On his return Broly meets Goku and the inner conflict is evident as Paragus restrains Broly with his hand remote. Broly's violent past is revealed as he destroys planet after planet with no regard even for his father. Paragus had a scientist craft a device to control his son’s power. Goku and Broly were born on the same day and though Broly move powerful he was overcome by Goku's crying. During the night Broly attacks Goku. Each holds their own until the fight is interrupted by Paragus and his hand remote. Goku through the fight realizes that Broly is the Legendary Super Saiyan. Goku tells Vegeta what he has learned about Broly. Paragus is really out to take earth and regain Saiyan dominance. Broly is unstoppable and Vegeta's attack doesn't even faze the possessed Broly. Broly snaps and goes Super Saiyan. Did I mention that this soundtrack is awesome!! For the first time ever Vegeta is shocked and too afraid to even fight. Paragus enlightens Vegeta as to how Broly saved himself and his father from Planet Vegeta before it was destroyed. Goku, Trunks, and Gohan go Super Saiyan and attack 3 one 1. As the fight heats up Broly attacks Gohan trying to enrage Goku. Trunks and Goku get close lined through about ten buildings by Broly.

Vegeta is still at awe of Broly's power. 4 on 1 Piccolo, Trunks, Gohan, and Goku attack Broly. Meanwhile Krillin, Master Roshi, and Oolong escape on Piccolo's ship. Broly continues to dominate the fight while Vegeteta finally steps in to lend a hand. Saiyan Pride does little to let Vegeta stand a chance against Broly. Paragus is about to leave when Broly finds him in a one man ship and crushes father like it was a pop can. Piccolo decides that channeling their energy to Goku is their only hope. All but Vegeta donate but it won't be enough without help from the Saiyan prince. It’s not enough and Goku is taking a beating. Broly is on fire and uses Goku as a human spring board. Vegeta fatefully gives his energy to Kakorat.  Goku is finally able to put up a fight and matches Broly impressively with one punch Goku blows up Broly. In a tangle of metal and Capsule Corp Logos the Z Teams lands in the middle of space.
