After meeting with the Artificial Humans on the island Trunks said they would appear on, Gokou tells the Artificial Humans to follow them to a place where their fight would have no interruptions. The androids agree and they fly off with Gokou, Piccolo and Tenshinhan. Kuririn stays behind and takes Yamucha to a nearby cliff where Buruma, Gohan and Yajirobe are. You see, Yamucha was the first to discover the androids and Number 20 wasted no time in showing his superiority by grabbing Yamucha by the head and punching his fist through Yamucha's torso. (I hope you're still with me, this is all very hard to put in writing.). So anyway, after Yamucha gets his Senzu, he's fine of course but he doesn't want to go with Gohan and Kuririn to meet up with Gokou and the others. He's too terrified by the power of the androids. But after about a minute he gets angry at himself for being cowardly and follows Kuririn and Gohan. Okay, so lets review. Here's the entire day's events so far in short. Gokou, Yamucha, Tenshinhan, Piccolo, Gohan, Buruma and Yajirobe met up on a mountain at 9 O'clock in the morning after three years of hard training. Yajirobe gives the group a bag of Senzu, then takes off in his air car. But he doesn't get far. His car is shot down into the water. It's the work of the androids. Gokou and gang try to sense the android's ki, but they can't. The android's ki is undetectable. So they all fly off into the streets of the busy island city in search of their enemies. Gohan is told to remain behind on the mountain. Hearing some screams from the android's first victims, Yamucha rounds a street corner and the androids sneak up behind him. Number 20 grabs Yamucha and puts his fist through Yamucha's body. Gokou and the other sense a disturbance and fly to the source. They find themselves face to face with the androids. Number 20 shoots an eye beam attack at Gokou. Gokou dodges the beam, but it continues beyond him and destroys most of the city. Gokou gets ticked and throws a quick punch letting Number 20 know he wants him to stop. Number 20 is pushed back a step by the punch, but there's no damage of any degree. Gokou then asks them to fight in a place with no distractions, (i.e. People, buildings, living organisms that could be harmed.). Number 20 agrees as he and Number 19 follow Gokou, Tenshinhan and Piccolo to a plain located on the nearby island. Meanwhile Kuririn takes Yamucha back to where Gohan, Buruma and Yajirobe are. He gives him a Senzu, and Yamucha's back in shape. Kuririn and Gohan then leave to catch up with Gokou and the rest. Yamucha contemplates going with them, then eventually his pride gets the best of him, and ends up following them. Whew! Did you get that? I sure hope so. Because the fight is about to begin.

Gokou wastes no time in telling Number 20 that he forgot the most important skill of a Saiya-jin, being able to turn Super Saiya-jin. He immediately turns Super Saiya-jin with the now typical fanfare, (scream, wind, big ki, etc.). Number 20 is hardly impressed by Gokou's transformation, "It's true that you've powered up quite a bit, but you're still no match for us. Number 19 or I alone could defeat you.". Gokou smirks, "Is that so? Well let's see just how strong you are.". Gokou rushes Number 19. The android tries to grab his head, but he gets nothing but air. Gokou's already behind him. However, not being easily tricked, 19 instinctively kicks behind him, but Gokou blocks it. 19 suddenly launches a furious barrage of punches and kicks all of which Gokou counters effectively and skillfully. 19 stops for a second and hops backwards several yards then leaps into the air, his face covered with a smile the entire time. Gokou follows his movements. 19 suddenly dips down behind a nearby mountain and from his position, fires a blast straight up at Gokou. Gokou shields himself with his hands, leaving himself blinded. 19 anticipated this and rears back to deliver another energy blast at him. Gokou dodges by doing graceful back flips through the air, and heads straight for 19 again. 19 retreats to the ground while Gokou dances from side to side on his descent, anticipating any further attacks, until he finally lands on the ground, only to disappear again when 19 tries to punch him but, once again, only succeeds punching air. Gokou appears with his back to 19's and elbows him in the kidney. 19 cries out in agony as he's sent flying into a small rock formation, (funny how he can feel pain seeing as he's an artificial human). Number 20's eye's practically pop out of their sockets as he watches Gokou toy with his comrade. 19 coolly pulls himself out of the rubble and hurls himself headfirst at Gokou. The Saiya-jin just puts out one hand and stops him in mid-flight. 19 looks up confused, but doesn't have long to savor his surprise as Gokou punts him straight into the sky. Gokou appears behind 19, but not being a simple-minded fighter, 19 instantly turns around and greets Gokou with a volley of punches, and of course, Gokou dodges all of them., but this time, his features give away that he's distracted by something. Finally, Gokou finds an opening and uppercuts 19, then follows it up with a sharp kick to the Artificial Human's stomach. 19 lets his anger get the best of him and charges Gokou blindly, but Son grabs 19's appendages and elbows him in the face. Meanwhile, Tenshinhan "oohs and ahhs" Gokou's performance, but Piccolo can tell that something is not quite right with Gokou. Finally, the battle reaches a short break and it ends with Gokou breathing heavily. He's exhausted, although he tries not to show it. 19 just stares at him, not moving a muscle. Gokou makes the first move and rushes 19 with a series of slow, but powerful physical assaults; hitting the android in the chin with his knee, a round-house to its face, then letting fly with several fast blows to the face and chest. 19 screams in anger and then becomes offensive, forcing Gokou to dodge again. This time, Gokou is barely missing 19's punches, but of course, he finds another opening and uppercuts 19, then slams his fist deep into 19's stomach. Number 19 doubles over, giving Gokou plenty of time to carry out a punishing overhead smash to 19's jaw. Number 20 glares at Gokou and thinks to himself, "He's far more powerful than we expected. This is impossible! This is dangerous! Number 19 is going to run of energy before he can steal Son Gokou's!". At that same time, Kuririn, Gohan and Yamucha land next to Tenshinhan and Piccolo. Tenshinhan reassures Gohan that his father is doing an excellent job. Gokou continues to deliver blow after blow to 19, but Piccolo and Gohan both notice something is not quite right with Gokou. Piccolo inquires, "Why is he stretching this fight out? He was fighting at full power before, now he's not using much power at all". Tenshinhan points out that Gokou IS winning. But Piccolo rejects the statement, "He should be much stronger than even this.". Gohan suggests that maybe they're draining Gokou's energy. Yamucha supports the theory by relating how Number 20 sucked out his energy when he held his hand over his mouth. Their discussion is interrupted when Gokou kicks 19 into the ground. Kuririn shouts out, "He did it!". But of course that was a premature statement, seeing as 19 rises from the dust moments later. His clothes are a bit tattered, but otherwise, he looks to be in fine shape. Gokou on the other hand is another story. He's almost completely spent. His body heaves with each breath he takes in. Gokou looks down into 19's unraveled eyes and gets angry, "Shit!". He cups his hands together and forms a Kame Hame Ha. He charges for a moment, and then releases it at full power. 19's face lights up like a child on Christmas morning. He sticks his hand out triumphantly and smiles gleefully. The blast lands on top of him, and he disappears for a second, but it can then clearly be seen that he's sucking the Kame Hame Ha into his body from the red ball on the palm of his hand. After it's all inside of him, he lets out a pleasant sigh. Gohan, Kuririn, Tenshinhan and Yamucha are absolutely flabbergasted by what they just witnessed. Gokou can't even do anything but hover in the air and breath heavily. Yamucha comes up with a stunning observation, "They steal energy through their hands!". I think Yamucha deserves the genius of the century award for coming to that amazing conclusion. Let's all give him a round of applause. Piccolo yells a warning to Son, telling him not to shoot energy blasts at 19. Gokou just barely gets out, "They can absorb ki?", he laughs, "That’s not funny.". Number 20 barks out, commanding Number 19 to take this chance to attack since he's received fresh new energy. 19 obeys and flies up to Gokou. Gokou barely misses a punch he throws. Gokou connects with a punch to 19's face, but the Artificial Human just smiles evilly. He knees Gokou in the stomach, Gokou retaliates by elbowing him in the face, but it has no effect. 19 slaps Gokou aside, drawing blood from his mouth. Number 19 slams Gokou in the chest, sending him hurtling towards the ground, but Gokou stops himself before he hits. On instinct, Gokou fires a ki blast, but Piccolo reprimands him, and he quickly dissolves it. Son curses, "Damn it.". Finally, he floats down the ground and grabs his chest in pain. Once again, Yamucha the genius points out, "Hey, he doesn't look so good.". Finally, Gohan puts it all together and realizes what's going on. His father is finally suffering the symptoms of the viral heart disease he received on planet Yardrat. Everyone is shocked. They were under the assumption that it had already been done away with in the three years during their training, but obviously, they were dead wrong. Gokou falls on his knees and grips his chest while grimacing. He can barely lift his head up. Kuririn hurls a Senzu at Gokou hoping that it might alleviate the condition, but it's to no avail, like Trunks said, even the Senzu beans can't cure it. While Gokou's munching on the bean, 19 fires eye beams at him. Gokou avoids the explosion by flying straight up, but 19 appears right in front of him gives Gokou a sock in the jaw, and he doesn't stop there. He pounds Gokou's back, then knees him in the stomach and finishes by slamming Gokou into the ground far below them. Before he even has time to stand up again, 19 charges into him head-first, then tunnels underground and shoots up underneath Gokou sending him back into the sky. 19 attacks Gokou violently from all angles then punches him about one hundred yards back. 19 materializes behind Gokou to deliver the final blow. He kicks him in the back letting his opponent hit the ground hard. He lands near Gokou's crash landing, his face covered in a grin. Gokou's body flashes for an instant, and he returns to his normal state. He can now barely move his head around. 19 flips around in the air and lands, sitting on Gokou's stomach. He pins Son's hands down with his feet and pushes down on them repeatedly for good measure. Gokou's face twists in pain. 19 holds his hand over Gokou's face, his victim's pained features are reflected in the red energy-absorbing ball on the palm of his hand. The android grips Gokou's throat and begins to suck out his precious ki energy. Gokou frees his hands and tries to pry of 19's vice-like grip, but it's no use. He's not even in the shape to, "pick his own nose", let alone be fighting for the future of earth. 19 looks over at the Z Soldiers and smiles demonically while the stolen ki circles around him. They all fly over to help Gokou, (gee, that seems like a pretty good idea seeing as how he's suffering from a heart attack!), but 20 appears in front of them, warning them to stay out of the fight, "Unless you want to test me.". Piccolo takes up the challenge but 20 just sends eye beams to his stomach, downing him in an instant. 20 gloats, "You can't call what he did bravery, that was just being a reckless fool.". Meanwhile, 19 continues to suck energy out of Gokou. Eventually, Gokou begins to feel the effects of the drain and his hands slowly fall off of 19's. He begins to lose consciousness and just as he's about done for, a foot comes out of nowhere and knocks the smile off of 19's fat face. The Prince of the Saiya-jin has arrived! "It's my job to defeat Kakarroto. This is not a task you puppets should take on.". While everyone is busy amazed at Vegita's arrival, Piccolo rises to his feet, unscathed, "Damnnit. Vegita, you're getting in my way. I pretended to fight poorly so I could catch them off-guard and save Gokou.". Gohan inquires how Piccolo resisted the powerful attack and he responds, "No matter how powerful these fools are, a weak attack like that would never hurt me.". On the battlefield, Vegita reprimands Gokou, "I saw everything. You idiot, you knew your body was damaged, yet you still turned into a Super Saiya-jin. Doing that will just make your disease all the more worse. My final target is you alone Kakarroto!". With that Vegita kicks Gokou aside right into Piccolo's waiting hand. After some more bantering, Yamucha is assigned to take Gokou back to his house so he can get the medicine. And with that said, Gokou's battle with Jinzouningen 19 comes to an end. But don't worry, Vegita eventually takes out 19 with a couple new tricks he's learned over the past three years, like the ability to become a Super Saiya-jin!
