Mr. Popo quickly takes Broly to a small rustic house on the mountains. Broly asks, "Sensei, where are we?"
Mr. Popo tells him, "This is Goku's home. He will arrive here in a few seconds and you will ride with him to Master Roshi's house. I must go now." Mr. Popo then vanishes while Broly is about to ask a question.
Goku then arrives and shouts, "Hey! Broly!" They then wave to each other as Goku lands the Nimbus and goes into the house to put on some clothes.
Broly goes in and borrows a matching pair of clothes. But he takes the scarf he's used as a makeshift skirt and uses it as a sash now. They then pack up some stuff onto the Nimbus and Broly holds on to dear life to Goku as they go to the pink house on a tiny island called Kame House. When they land, they find Roshi inside, watching a women's exercise videos.
Goku decides to scream in his ear to get his attention. Once that is done, he mumbles, "Ah, Goku, Broccoli, nice to see you. If you'll excuse me, I gotta finish this video." After the video, with Goku cleaning out Roshi's fridge, Roshi goes off looking around the island for Bulma. He tells them, "My lessons aren't free. Find me a pretty, young gal, it's the only way to be accepted."
Broly asks, "I can't ride the Nimbus, do you mind if I stay here till he comes back with someone?"
Roshi nods in a yes motion. Goku then flies off on the Flying Nimbus. While they wait, Roshi puts on a dark red tuxedo and a pink turtle shell while Broly is reading his first ever magazine on one of the lawn chairs. Goku returns with a giant, fat woman carrying giant weights in her hands. Roshi sends him out again while Broly starts laughing his butt off. Goku left to get another, but brought back a mermaid that slapped Roshi across the face.
Suddenly, Goku shouts, "What is that!?" Broly and Roshi look to see a small boat heading for the island. In the boat is a bald boy wearing yellow robes. The boat stops a couple feet away from the island, then the boy jumps towards the island, but buries his head in the sand. Goku and Broly help him get out of the sand.
The boy announces, "My names Krillin, Master Roshi, and I've traveled far to train with you."
Roshi declines the offer, then the boy picks up his purple bag and dumps out a large amount of dirty magazines, to which the older martial artist quickly takes back his rejection. He then asks, "Who are you two?"
Goku tells him, "My names Goku and this is Broly. We came here to train as well." Goku and Krillin then set off on the Nimbus to find a girl Roshi will like.
Broly then grumbles, "Shame the Nimbus can't hold 4 people." Then after a while, Goku and Krillin return with a girl who has dark blue hair.
Broly asks, "So guys, who's the girl?"
She says, "Oh hello. My name is Launch."
Krillin then tells her, "That's Broly, a fellow student of the master." They go off to have conversation with each other that Broly isn't paying any mind to. Roshi finally comes out of the house to see the girl. He shouts, "Goku! Krillin! Broly! You are officially my students!"
He then makes everyone on the island wear skimpy black women's underwear for uniforms. But as they start, a bug flies by everyone and makes Launch sneeze, where her hair suddenly turns blonde and starts shooting at the gang. But then she sneezes again. After this, Roshi shrinks his house and replaces it with a speedboat for them to move to a larger house. The students and master then test each other in a sprint, with Roshi winning.
The Turtle Hermit then throws two rocks with a kanji written on them. He then says, "Ok. Find the rocks if you want dinner." Broly found one, and Krillin took the one Goku found. Broly tries to offer Goku food, but Roshi tells him no. Then the dinner guests get sick because Launch made Pufferfish for dinner. They get horribly sick and have to wait to get better. Luckily, they do and don't die. In the morning, the students wake up early and start training.
The training starts with a jog around the island. They then stop in front of a house with a helicopter outside. Roshi shouts, "Hello! Good morning!"
A goat man walks out and says, "Ah, you're here! Here's the delivery route. Are you sure that you don't want the helicopter?"
Roshi answers, "No thank you, this is exercise for the boys." The students then grab a crate of milk and start jogging around the island to houses that are miles apart, trying to get to each house early.
While hiking up a mountain to the next house, Roshi tells them, "Did you three know, that my previous students Gohan and the Ox King did this exact same training?"
This got Goku to move faster, Broly then tells Krillin, "As the French say, allons y." And the two catch up to Goku. They finally finish the delivery and are now sprawled on the ground resting.
Roshi then tells them, "If you do this enough, you'll be eligible for the World Martial Arts Tournament."
The monk that lives at the house exclaims, "That's in only eight months!"
Krillin shouts, "The World Martial Arts Tournament!? The festival where all the great fighters meet to do battle with each other held only five years!?" They then get off of the mountain and finish the deliveries. When they finish, they then start the afternoon training. They dig up a plot of farm and make a crop with their bare hands.
Then they study books and math, and then just nap. Then they work construction with no power tools. Roshi also has them swim laps in a lake filled with sharks. Then they are tied to a tree with angry bees flying around. After that, they looked completely red. They repeat the process for days, while wearing 50 pound turtle shells.
Minutes turn to hours, as days turn to weeks. And after who knows how long, the students are able to meet Roshi's original expectations. Roshi then says, "Wow, you boys have finished your training. You've successfully pushed yourselves to your very limits. Your training will resume, but with 100 pound turtle shells from now on." Then the tournament comes by and the students go to the tournament in tuxedos given to them by Roshi.
Goku and Broly ride the airplane for the first time in their lives. Then they arrive at the WMAT and sign up. They then meet up with Yamcha and the others, and Yamcha cropped his hair. When they sign up and prepare to fight tomorrow, they get orange turtle school gi. They then prepare to fight over 130 martial artists. The gang pick their numbers and are grateful they don't have to fight each other.
As the first round winds down, Krillin meets with some of his old bullies and they torment him again. But when Krillin fights them, he beats the living crap out of them with one kick. They all make it past the preliminaries, with Broly beating up some dragon monster. With the preliminaries over, the students have to endure the horrid smell of fighter Bacterian while gauging fighters Ranfan, Nam, and Jackie Chun.
The blonde haired, sunglasses wearing announcer arrives and calls up the fighters. He asks for, "Bacterian, Ranfan, Nam, Jackie Chun, Yamcha, Krillin, Broccoli, and Gokea." But Yamcha corrects him, "Sir, its Broly and Goku." The first match is Krillin against Bacterian, Yamcha against Jackie Chun, Nam against Ranfan, and Broly against Goku. Krillin is freaking out due to his opponent, while Broly and Goku are excited for their fight.
The match between Krillin and Bacterian starts with Krillin keeled over due to his opponent's foul smell. But when it all looks bleak, Broly shouts, "Krillin! Don't you realize you don't have a nose!?" And Goku shouts with him, "He's right! How can you smell when you don't have a nose!? It's all in your head!" Krillin gets up, roundhouse kicks Bacterian in the face, and then farts on him, winning his match.
For Yamcha's fight, he goes on the offensive to gauge the old man, who effortlessly dodges his punches and kicks. But when Yamcha uses the Wolf Fang Fist, Jackie Chun dodges and slaps the air, causing a sudden increase in wind speed and knocking Yamcha out of bounds. During Nam's fight with Ranfan, he keeps blushing when Ranfan won't stop winking at him. This gives Ranfan the opportunity to attack Nam repeatedly.
When Nam prepares to punch her, she screams and it makes him stop. He then chose to simply tap her shoulder, making her fall over and cry like a toddler. This makes Nam apologize profusely. But it was all an act, and Ranfan continues to beat up Nam. But Nam catches a punch and then starts to fight her once again, but Ranfan then strips to her underwear, making Jackie Chun start laughing a vulgar laugh. This made Yamcha come up with a theory on the elderly fighter.
Back with the fight, Ranfan started walking confidently towards Nam, making the timid man step backwards, almost out of the ring. But when Nam closes his eyes, Nam jumps back into the fight, and karate chops the back of her neck, knocking her out cold, allowing him to win. Goku and Broly step up to fight next. Broly starts with a roundhouse kick into Goku. Goku charges at Broly, where they start to exchange punches and kicks. The fight goes on for a while, with both fighters proving to be fairly equal in strength.
After they catch their breath, Broly tells him, "I didn't want to use this again, not after last time. But I guess I have no choice."
He then touches the back of his neck and prepares to do something, but the Announcer asks, "I'm sorry, Broly, but what is it you plan on doing?"
Broly told him and the entire audience, "I was told that when I was born I had incredible power, power so great that my father had it sealed away. After a couple of years, the seal started to become visible."
He moves his shaggy hair around to show a tattoo of the Yin Yang symbol, with one part red and another blue. He then continues, "About a year ago, my father thought that I could handle this great power, and removed the lock on the seal. It turns out that I wasn't ready so my father had to seal it back. When it was, he told me that the people of the planet thought it was either a violent lightning storm or a meteor shower."
Bulma then shouts, "You!? You're the cause of that Meteor Shower!? That was so powerful it would've destroyed the world!"
Jackie Chun ponders, "If this boy is that powerful, then where did he come from?" Goku then tells him enthusiastically, "Well why don't you remove it!? I want to see how powerful you are!" Broly does just that, and suddenly, his pupils shrink and his eyes widen. Then he lets out a blood curdling scream as he becomes taller and more muscular, ripping through his shirt. And suddenly, he makes no noise, and then he just starts laughing, maniacally.
He then shouts, "Finally! My full potential has been freed!" Then he points to Goku and shouts, "And you, Kakarot, will be the first to feel my wrath for all the torment you've caused me!" Goku is confused, then Broly asks, "What's the matter? You're walnut sized brain can't comprehend this? Well allow me to explain: We were born on the same day! All you did in that crib right next to mine was cry, cry, cry, and cry! You drove me insane for reasons nobody knows!"
He then exclaims, "World, I am Broly of the Saiyan Warriors! And I will kill you all!" Suddenly, a cloaked man with absolutely no distinguished feature other than his visible eyes appears and says, "Broly! Don't do something you'll regret." And Broly just tilts his head and says, "Ah...The adopted father appears. Why must you interfere with this battle of destiny? I want my justice!" Broly jumps up in the air and charges at Goku, who barely dodges.
He then charges at Goku, who jumps into the air, with Broly following. Goku lands a kick on Broly, who fires a green energy sphere at Goku, who then manages to dodge it. But Broly absentmindedly lands outside of the ring while Goku lands in the ring. Broly charges at Goku again, who punches him in the face, where the cloaked man then taps Broly on the back of his neck, activating the seal.
At that moment, Broly returns to his original form. Bulma mumbles, "He promised to kill us all." While Oolong mumbled, "I hope that doesn't get undone again." And Puar asks, "What's a Saiyan warrior?" And Launch, in her blonde hair state blurts out, "I'm in love." Broly then goes to the announcer and grabs the microphone and says, "To all who just witnessed what I did, I am sorry." Then he returns to the training room while his father vanishes. When the fights for the semi finals are called up, Goku's tail returns.
The match between Krillin and Jackie Chun begins. Everything Krillin does, whether it be a punch or kick, is dodged by Jackie Chun. But Chun catches one punch and does minute movement that sends Krillin to the only wall that is safe to touch. Krillin gets back up and through some pep talk between Goku and Krillin that Broly couldn't hear from where he was, he charges at Jackie Chun. They fly past each other, but Krillin passes out first.
After Krillin gets back up the announcer asks for a demonstration of what just happened, and it was just strange. Broly saw everything that happened before, but finds it strange in slow motion of the spitting, rock paper scissors, and somersaults. After that, Krillin throws out a pair of panties. When Chun charges at them, Krillin kicks him in the face. But then, Jackie Chun fires a Kamehameha to get back in the ring.
Out of pure desperation, Krillin charges at Jackie Chun, who then makes an afterimage of himself, giving Chun the chance to knock Krillin out cold. After the match, Yamcha tries to rip off Jackie Chun's hair, but it won't come off. The next fight between Goku and Nam then begins. Goku smiles and uses the afterimage technique. But Nam dodged and tried to kick Goku, who dodged that as well.
Nam then releases a barrage of kicks that Goku blocks with one hand. Goku then starts punching with Nam blocking. Nam then chops Goku on the side of the head, making him fall over, but Goku stands back up again. Goku then makes himself spin around like a tornado and pushes Nam nearly out of bounds. Nearly, till he got dizzy. While Goku is down, Nam jumps into the sky. He then flies back down, with his arms making an X, and charges straight for Goku.
As Goku wakes up, Nam's X shaped arms land right on Goku, knocking him out. The announcer starts counting down. But at the last second, Goku just gets back up. Nam then jumps up again, only higher. But then, Goku jumps up following him. Goku goes higher than Nam and then goes back towards Nam to fight each other while falling. Nam throws a punch, but Goku dodges and they both fly closer to the ground.
Goku lands first and then kicks Nam out of bounds. Privately, Jackie Chun approached Nam and handed to him a capsule. Jackie tells him, "That's a storage unit. You can fit things such as food and water inside of that."
Nam asks, "How did you know?"
Jackie answers, "Minds are like books Nam. They're easy to read if you know how." Nam then shouts, "So you are Master Roshi!"
Roshi then shushes, saying, "Be quiet. They can't hear the truth. The ones in orange gi are my students. They each have tremendous talent, one of them even showed he has the power to destroy the planet. I came to make sure that they lost, so that they don't get an inflated ego if they win. So I put on a glued on wig and made up the name Jackie Chun to beat them."
He pauses and asks, "Can you do me a favor and dress like the regular me in the audience to convince them that I'm not Roshi?" And Nam answers with an approving nod. As Nam goes off, Roshi goes off for the final battle. As the match begins, Broly blurts out, "Amazing, it's almost like they're on fire." Jackie Chun charges at Goku, but Goku jumps over him. Jackie Chun then jumps after him, with a kick being prepared.
He kicked Goku in the back as he was falling back to the ground. But just as it seemed like Goku was going to be out of bounds, he used his tail to turn himself into a human helicopter and landed back in the arena. Roshi then prepares the Kamehameha, while he asks, "I understand that you know the Kamehameha wave, I want to see yours against mine." And they both use the Kamehameha, which Broly is amazed by the first ever energy beam struggle.
The impact of the two attacks pushed both fighters to the ground but not out of bounds. The two get up and Jackie makes an afterimage, Goku attacks one of the two, but attacks the wrong one, and Jackie Chun kicks him in the back. Goku is down and the announcer starts counting. But at the last second, Goku stands back up. Goku then copies Jackie Chun's double afterimage, but instead does a triple afterimage.
Goku shouts, "I've got it! I know why you look so much like master Roshi! You're his brother!" Jackie Chun then tells him, "We are family, but we're cousins, not brothers. But now we have a match to finish." Jackie Chun then starts tripping over his feet and acting like a drunk fool. During this time he slaps Goku on the top of his head. Then he kicks Goku in the chin. Yamcha then yells, "Don't be fooled, Goku! He's using the Drunken Boxing Technique! He's pretending!"
Goku tries to attack, but gets hurt anyway. This repeats over and over again. Goku then runs into a corner, and then turns around with a feral look and walking on all four. He lunges at Jackie Chun, lands behind him, and then dodges a punch after Jackie Chun turns around. He keeps dodging the punches, till Goku dodges and sits on his head now. Then he lands behind Jackie again and wraps his tail around Roshi's ankle.
Goku trips Jackie with his tail. Then Goku jumps on Jackie and starts scratching at him. Goku then jumps off, when Jackie stands back up with ruined hair. Goku then shouts, "Crazy Monkey Technique!" Goku then starts to beat up Jackie Chun profusely. Jackie then says, "Don't get cocky. I've already won." He then starts making hand movements and gestures. Jackie then says in a hypnotic way, "You are so sleepy." And suddenly, Goku falls asleep.
The announcer starts counting down, with the entire gang yelling their own forms of wake up. But at the last second, Bulma yells, "GOKU! YOUR DINNER'S READY!" Suddenly, Goku wakes up and is standing tall, with a little saliva being drooled out. He then starts looking around till Bulma promises him food after the fight. Goku charges with the Rock Paper Scissors attack, but Jackie blocks them. Goku tries again, but instead of paper, he uses rock.
He punches Jackie right in the nose. Jackie gets back up and stands tall and tells him, "I'm sorry, but you have lost the match. I'll try to make it quick." He then rolls up his arm sleeves. He continues, "I don't really like using this technique, it's an emergency attack if nothing else works. This is the second time I've used it, the first time was on your grandfather, the great warrior Gohan." He then claps his hands together and concentrate.
Then his hands started to glow with lightning sparks. He stuck his hands forward and then yells, "Lightning Flash Surprise Attack!" And suddenly, Goku is struck by lightning. Yamcha then shouts, "Jackie! That's 20,000 volts of electricity! You'll kill him!" Jackie then screams, "Say that you give up! You'll die if you don't say it!" But Goku stutters, "I'm not quitting!" Broly thinks to himself, poor Goku, he's never lost a fight and doesn't want to start. I kind of admire that sense of pride.
And just as Goku is about to say it, he suddenly saw the full moon. And with his grown back tail, he transformed into a great ape, freeing himself from the lightning attack. Broly sees this at the early stage and yells, "Everyone run! Get out of here now!" Most are confused, but the gang looks to see the full moon. Broly then shouts again, "Quick! You must leave! Goku is transforming into a great ape! He won't control himself and will attack anything and everything!"
Yamcha then yells, "Broly! Try and transform as well!"
He tells him, "I can't anymore! Before my father left he saw my tail growing and removed it permanently!" Goku then starts destroying the buildings surrounding the tournament arena. The audience finally leaves after this. Jackie Chun then removes his black shirt and bulks up, using the powered up Kamehameha. Yamcha yells, "Don't fire! You'll kill him!" But he fires anyway.
The light is gone, and there is no sign of Goku. When the light faded, he heard Bulma instantly crying. He had trouble holding back tears himself. But then, he yells, "Where's Goku!? What have you done!?" He just says, "Calm down. Goku is alive, he's sleeping right here." He points to Goku's tail, and it is moving like a dog's would if it's absently moving. Goku rolls over, and is alive, if naked.
Jackie Chun tells the audience, "Goku wasn't the target. The moon was." Broly then mumbles, "Well if the moon was gonna be destroyed, why did I get my tail removed?" It was obvious he misses his tail now. The announcer then starts saying things we'd miss about the moon, but just as he finally starts counting down, Goku wakes up. But before the fight continues, Krillin lends to Goku his clothes, changing back into his yellow robes.
Both fighters have heavy fatigue, Jackie from destroying the moon, and Goku from hunger. Jackie tried to make a Kamehameha, but it was a sizzle. Goku uses one that Jackie manages to dodge. Goku kicks Jackie as he is returning to the ground from the jump he made. Jackie nearly lands outside the ring, but a kick into the side of the arena saves him. Jackie climbs back into the arena and the fighting continues.
But the fighting is now punches and kicks. By the time they are at their limit, they are heavily bruised and exhausted. Jackie then asks, "What about one final charge?" Goku and Jackie Chun then charge at each other. Then they kick each other in the face. When both fighters fall, the announcer starts counting down. Both struggle to stand up, but neither of them could stand. They both now have to just stand up and declare themselves the winner.
Goku stands up first, but before he can finish his declaration, he falls asleep. Jackie Chun wins the match, fulfilling the purpose Master Roshi asked for. But Goku lost the first match he ever really fought to his full potential. But Broly admires that he didn't get a ring out like he did. And When Goku got up, he was happy, with everyone knowing he did the best he could, and even though he didn't win, he learnt something: He needed to be stronger.
Everyone met up again, with everyone very happy now. Master Roshi arrived last. He then takes everyone to some restaurant to celebrate. Both Broly and Goku were drooling a river for food. When everyone had dinner, Goku and Broly ate the most, with Bulma saying, "Those two ate 57 full course meals. Separately." Then they asked for dessert. And the cashier told Roshi that it would cost him his entire cash prize.
A/N: Ok, so when the Saiyan Saga will begin, Broly will start recruiting allies for the battle with the Saiyans, such as World Martial Arts Tournament fighters Ranfan, King Chappa, and characters that will appear sooner like Hercule. Hell, even Chi Chi will be fighting. Also, I think that due to there being Broly on the planet, Vegeta and Nappa will pick up some extra Saibamen. But instead, they'll be the new colored Saibamen introduced in Dragon Ball Xenoverse. Also as an explanation, I had Broly release his full potential so that it would be easier to explain how he'd lose.
