A Saiyan spacepod lands on earth. But who's that inside? It's a completely beaten up Brolly. he falls out of the spacepod into the water, and he get's frozen by the water.
Goten, Trunks, and Videl are in search for the dragonballs, because Goten wants to wish for his own themepark. They find the first dragonball, and then see that the second one is in a nearby village, so they head off. The village shaman is in the middle of the sacrifice to the gods, so the horrible monster that's terrorizing the village will go away, and he's sacrifizing ... a girl! Since Goten still wants his themepark, he and Trunks propose to kill the monster, if they get the dragonball afterwards. While they are trying to lure the monster with a big pot of food, Trunks steals some. When Goten tries to too, Videl hits him, and says no. Goten starts crying because Videl hit him and Trunks DID get some food. The awful sound wakes Brolly up. Videl can't stand the crying, so she gives Goten some. When Goten finished his food, he tells Videl that he was just pretending to cry. Finally, the horrible monster is there, but...it's just a dinosaur... Goten and Trunks tease him a little, and then punch him in between his eyes, which knocks him out. then they cut him into pieces (that's easier to eat). Grateful as the villeg is, they give the dragonball as reward.
They go to sleep, and when they wake up, Videl is being beaten up by Brolly. Goten and Trunks rush to save Videl. When Brolly arrives, he thinks that he is Kakarotto, so he desperatly wants to kill Goten. Goten and Trunks attack Brolly, but they arent strong enough to actually hurt him. Then Goten locates the 4-star dragonball. While Trunks distracts Brolly, Goten fetches the last dragonball, so they can summon the eternal dragon. Goten puts the dragonballs on the ground, and tries to get the dragon to come out, but nothing seems to happen.
Gohan is flying around, and suddenly senses an enormous power rating. He decides to check it out, and finds Brolly. Gohan is scared, and surprised that Brolly is still alive. Didn't Goku kill him? Gohan joins in the fight, but it appears to be rather useless. Then they Gohan spots a canyon with lava flowing through it. He suggests to throw Brolly in there, since that might be the only way to stop the Legendary Super Saiyan. Gohan leads Brolly into the lava canyon, but Brolly knocks him out on some rocks. The lava is about to cover up Gohan, when suddenly the wellknown white cape and purple gi saves gohan, and brings him to safety on some rocks. When Gohan wakes up, he thanks Piccolo. But wow! It's Krillin in Piccolo's clothes!!! Then Brolly kicks Krillin into some rocks, and appears to be undamaged by Gohan's trick. then Gohan fires a big Kamehameha at Brolly, but it's blocked by Brolly's Green Fire orb. Goten appears to have been able to get the dragon out, but he has to help Gohan, and fires a Kamehameha to aid Gohan, but it's still not powerfull enough. Goten and Gohan are barely holding out, so Goten says he'd wish his dad was there. Suddenly a ghost of Goku appears and fires a Kamehameha together with his 2 sons. Brolly still overpowers them. Trunks then throws a fireball at Brolly, which distracts him. Goku, Gohan and Goten fire their Kamehameha to maximum power now.
Brolly looks back, and sees a huge fused Kamehameha wave. He tries to block it with another one of his Green Fire orb, but it isn't strong enough. Brolly gets blasted into the sun, and explodes there.
Once again, no good guys died, evil has been eliminated, everything returns to normal...:D
