Valiant Fight! Violent Fight! Super Exciting Fight!

Summary-

Goku and Chi Chi go to interview for a school that Chi Chi wants Gohan to attend, while everyone else is busy partying at a Cherry Blossom-Viewing Drinkfest. Krillin starts singing and everyone is surprised how good he is. The party is disrupted when a ship lands. Paragus steps out to invite Vegeta to travel with him to the planet New Vegeta, to fight the Legendary Super Saiyan which is when Vegeta realizes Paragus is himself a Saiyan. A drunk Master Roshi, Krillin, Trunks, and Gohan fly off as well. Meanwhile, King Kai contacts Goku to alert the heroes of the danger. Goku teleports out of the interview, leaving Chi-Chi in the lurch.

Paragus introduces Vegeta to Paragus's wimpy son, Broli, and waffles over actually disclosing where the Legendary Super Saiyan is. Goku teleports in and Broli goes berzerk. We then find out that Broli and Goku had been born on the same day and Goku cried a lot which made Broli develop an instinctual hatred because his crib was right beside Goku’s. King Vegeta had ordered Broli and Paragus to be killed and dumped in the trash because of Brolly’s great power. But, baby Broli's power saved them. Broli grew up to be a maniacal killer, and had poked out one of Paragus's eyes. Right after that, Paragus had a headband created that effectively lobotomized Broli.

Gohan, Krillin, and Future Trunks do a little investigating and soon find out that Brolly is actually the Legendary Super Saiyan. Brolly overcomes Paragus's control and turns into a Super Saiyan; he trashes everyone. Vegeta loses his nerve at seeing the Legendary Super Saiyan, and can't fight anymore.

Paragus knows that the planet will be hit by a giant meteor soon, so he wants to fly away, killing two birds with one stone: revenge on the Vegeta family, and disposing of his troublesome child. But, Broli crushes the space capsule, killing his father. Then, Goku summons the energy from his friends, including Vegeta, to become a Super Saiyan himself, and supposedly killing Broli. Before the planet explodes, Goku teleports everyone to Piccolo's ship
