Three years later.
The day Yun Feng predicted for the arrival of the Androids had finally arrived, and Goku and the others gathered to await his appearance.
"Dad, where did the big brother go to train? Why isn't he here yet?" Gohan asked.
"Master's power is heaven-defying; he likely went off to train on his own. Dad doesn't know where Master Yun is either, but he will surely arrive soon."
Goku looked at the baby in Bulma's arms. "Little Trunks, you mustn't grow up to be as grumpy as Vegeta."
Bulma was startled. "Goku, how did you know Trunks is Vegeta's son? I don't recall telling you that."
Goku had learned this from Yun Feng three years ago, but realizing he had made an awkward slip, he tapped his forehead. "Haha, I'm a Super Saiyan, after all. It's only natural I have a few psychic abilities."
Bulma didn't press the matter further. Suddenly, a figure in a cape and a white hat with a green face flew in—it was Piccolo.
Goku greeted Piccolo warmly. Aside from Vegeta and Yun Feng, everyone else had arrived: Yamcha, Krillin, Tien, Goku and his son, and Piccolo were all waiting.
Suddenly, a thunderous explosion erupted from a small island to the north. Goku and the others were shocked. "They're here! We have no choice, let's go—don't wait!"
The group flew toward the island. Goku shouted, "Once you encounter the Androids, release your energy to signal the others!"
Everyone nodded. When they reached the island, it was in total chaos; flames from the explosions had sent the populace into a panic. Goku's aura flared, expanding several times over. "Damn it, those bastards!"
The group scattered to search for the Androids. As Yamcha turned a corner, he spotted three figures. Just as he prepared to release his energy, the old man-like Android flashed forward and grabbed him by the throat, draining Yamcha's power directly into his own body.
Goku suddenly sensed Yamcha's energy plummeting. He flashed to the old man's position and kicked him, sending him flying and knocking his hat clean off.
Krillin and the others rushed over. Goku shouted, "Krillin, hurry and feed Yamcha a Senzu bean!"
Goku glared at the three Androids with fury. The old Android spoke: "So, it's Son Goku. We were just about to look for you, but it seems you've delivered yourselves to us. Let me introduce us: I am Android 20." He pointed to the fat one. "This is 19." He pointed to the red-bearded giant behind him. "And this is 15."
As 20 introduced his companions, a chill ran through Goku and the others. Piccolo suddenly noticed Goku panting; he wondered if it was just from anger, as it was impossible for someone of Goku's caliber to be winded from such a short flight.
Goku shouted, "Don't you want to kill me? Then follow me!"
With that, he flew off into the distance. The three Androids exchanged glances, 15 gave a nod, and the trio followed.
Before long, they arrived at a region filled with mountain peaks. Android 20 spoke up: "Son Goku, is this the grave you've chosen for yourself?"
Goku didn't answer; he descended. To his surprise, as soon as he landed, he saw Yun Feng standing on the peak waiting for them.
Goku said in surprise, "Master, how did you know we would come here?"
Yun Feng smiled faintly. "A secret." Everyone rolled their eyes.
Android 20 stared at Yun Feng for a long time before finally asking, "Who is this? He is not in our database."
Everyone sneered, and no one was kind enough to explain it to 20, causing the smile on 20's face to stiffen.
Yun Feng spoke up: "Goku, you take the lead. Let me see your progress."
The fat Android 19 stepped forward, flashing a sinister grin at Goku.
Yun Feng knew Goku's heart virus would flare up here, but he wasn't entirely certain because his own presence had already altered many events. Still, Yun Feng had the medicine ready; if anything went wrong, he would save Goku immediately.
Goku rapidly powered up. His hair turned golden, a golden aura erupted around him, and his combat power surged instantly. The ground began to tremble as waves of terrifying energy rippled outward.
A look of panic appeared on 20's face. "What is this? Why wasn't this in the data? Not only is there an unknown boy, but Son Goku's strength is far beyond what the records indicated."
Goku vanished, his body becoming a blur. He reappeared behind 19, who was looking around in confusion, and delivered a sharp elbow strike that sent 19 flying.
19 stood up as if nothing had happened, save for a bit of oil leaking from his mouth. Goku charged, and the two began to clash. However, the more they fought, the more Piccolo noticed something wrong—Goku's breathing was becoming increasingly labored.
Piccolo walked up to Yun Feng. "Mr. Yun Feng, Goku's condition doesn't look right today."
Yun Feng nodded. "It seems Goku's heart virus is flaring up." Piccolo immediately remembered the medicine Trunks had brought three years ago.
Yun Feng shouted to the battlefield: "Goku, pull back!"
Goku was already gasping for air; his recent Kamehameha had been absorbed by 19. Just as Goku tried to retreat, 20 blocked the others. "Don't get it twisted, you don't make the rules here."
They watched as 19 gripped Goku's neck, draining his energy into his body. Yun Feng couldn't be bothered to waste words with 20; he flashed past 20's defensive line and kicked 19 square in the face.
19 flew backward, crashing into a mountainside. Yun Feng immediately produced the medicine and forced it down Goku's throat, then turned to the others. "Who will take Goku back to rest?"
Yamcha spoke up: "I will. My power is of no use here, and after that contact with the Androids, I've developed a bit of fear."
Yun Feng nodded and handed Goku to Yamcha, also giving Yamcha a dose of the medicine, as this viral heart disease was contagious.
After Yamcha left, Yun Feng looked at 19, who was slowly walking back. "Little fatty, I'll play with you."
This nickname instantly enraged 19. 19 charged forward at high speed, but Yun Feng blocked the impact with his hand and kicked 19 away.
19 hovered in mid-air and suddenly shouted, "Kamehameha!" A silver-white energy wave blasted toward him. Yun Feng didn't even blink, simply waving his hand to swat the energy wave away.
Yun Feng vanished before everyone's eyes. When he reappeared, an energy blast was already striking 19. The sequence of moves was so fast that those nearby couldn't even react, and 19 was left stunned as he took the hit.
A massive crater was blown into the ground. Everyone stared at the hole. Just as Yun Feng landed, 19 suddenly erupted, lunging forward to grab Yun Feng's arm in a death grip.
19 laughed maniacally: "I won't let go! Even if I die, I won't let go!"
Yun Feng chuckled; this 19 was truly cute in his stupidity. A terrifying aura exploded from Yun Feng's body, blowing 19 away instantly, leaving him unable to offer any resistance.
Yun Feng fired a single energy blast. With a boom, 19 was reduced to nothing.
Yun Feng turned his gaze toward 20 and 15. 20's face turned ghastly pale, for he knew his power was on par with 19's—which meant he, too, could be killed in an instant.
Desperate, 20 cast a pleading look toward 15. 15 let out a cold snort and slowly stepped forward.
