Goku was a bit displeased as he witnessed Vegeta killing Kurd, who had initially been let go by Goku himself. He turned to Vegeta and asked, "Vegeta, why did you kill him when he had already begged for mercy and promised not to return to Earth?"
Vegeta glanced at Goku and replied, "Kakarot, my approach to enemies is to leave no room for doubt. I don't like leaving uncertain enemies in my future."
"Kakarot, I suggest you change your ways too. Kindness isn't meant for enemies. If it weren't for you letting Raditz go, neither we nor Frieza would have been able to find Earth."
"If it weren't for your lucky transformation into Super Saiyans, everyone present at that time would have died at Frieza's hands."
"So, Kakarot, consider yourself lucky!"
Goku hadn't expected to be lectured by Vegeta after questioning him. Moreover, Vegeta's words made sense, making Goku feel embarrassed. He scratched his head and said, "Alright, alright, I'll be more careful next time and make sure to distinguish between genuine and fake surrenders."
Upon hearing Goku's words, everyone fell silent. Was this what Vegeta meant?
After Frieza and Kurd's deaths, the remaining members of the Frieza Force were no match for the Z Warriors. They killed those who resisted and let go of those who surrendered and promised not to return to Earth.
Krillin sighed in relief and spoke to John Doe and Goku, "John, Goku, it's great to have both of you here!"
Indeed, the group had not realized the significance of John Doe and Goku until this crisis with Frieza. If not for them, Earth and everyone on it would have been destroyed.
Hearing Krillin's words, John Doe smiled and said, "We'll always be together, never apart."
"Of course, we're friends forever, and we'll always be together," Goku added.
Just as everyone was feeling happy, a powerful and unfamiliar energy suddenly appeared nearby, startling everyone.
Everyone, including John Doe, was shocked. They couldn't understand the situation. Weren't Frieza and Kurd already eliminated? Why was there still such a strong and unfamiliar energy nearby?
John Doe spoke up, "It's nearby. Let's go and see who this powerful energy belongs to." With that, John Doe flew towards the source of the energy.
Goku, Vegeta, and the others, including Bulma, who was riding on Yamcha, followed John Doe.
"Over there!" John Doe pointed forward. A person was standing on an empty space, facing away from them.
They quickly landed behind the figure, and John Doe asked loudly, "Who are you, and why did you bring us here?"
Hearing John Doe's voice, the stranger slowly turned around. John Doe immediately relaxed upon seeing the person's face, as it was Trunks from the future.
John Doe had been worried that changing history might prevent the events with the Androids from happening. However, he was relieved to see that Trunks had still come from 20 years in the future, proving that the Androids still appeared in the future.
Although John Doe knew who the stranger was, the others didn't. Krillin asked, "Who are you? Are you a friend or foe?"
Unexpectedly, when the stranger looked up at the group and saw Vegeta, his face turned red for some reason.
Despite everyone's inquiries, the stranger remained silent. Just as everyone was getting impatient, especially Vegeta, who was about to take action, Future Trunks finally spoke.
"Um, can I talk to Mr. John Doe and Mr. Goku alone?" Future Trunks asked.
Goku was taken aback when he heard that the stranger wanted to talk to him. He pointed at himself uncertainly and asked, "Do you really want to talk to me?"
Future Trunks nodded again.
John Doe walked over and patted Goku's arm, saying, "Let's go and talk to him. Let's see what he wants."
After saying this, the two of them walked up to Future Trunks.
To ensure their conversation wouldn't be overheard, Future Trunks pointed to a distant hilltop and said, "Let's go over there. I can only tell you what I need to say in private."
Hearing Future Trunks' words, Vegeta became increasingly annoyed. He raised his hand, ready to teach the stranger a lesson, but John Doe quickly stepped forward to stop him. "It's okay. After I talk to them, I'll tell everyone what we discussed. Please be patient."
After some persuasion, Vegeta finally calmed down and agreed not to disturb them during their conversation.
Under everyone's watchful eyes, John Doe, Goku, and Future Trunks flew to the nearby hilltop.
Goku took the lead in questioning the stranger, "Why did you call us here? Can you tell us now?"
Future Trunks glanced at John Doe and Goku and said, "Before I explain the reason for my visit, may I have a sparring match with you?"
John Doe and Goku exchanged glances, and John Doe asked, "Who do you want to spar with? Me, Goku, or do you want to challenge both of us?"
John Doe joked in the end.
Future Trunks quickly shook his head and said, "Mr. John Doe, you're joking. I don't have the ability to challenge both of you. I only need to have a brief fight with one of you."
Hearing Future Trunks' words, Goku eagerly raised his hand and said, "I'll do it! I'll spar with you."
John Doe didn't mind, so he stepped back a few paces.
Goku asked, "Okay, how should we spar?"
Future Trunks said, "If possible, Mr. Goku, could you transform into a Super Saiyan first?"
Goku was taken aback and asked, "Super Saiyan? Are you sure? My power is quite formidable in that form."
Future Trunks nodded.
Since the stranger insisted, Goku took a deep breath, and his body was instantly surrounded by golden energy. His hair turned golden, his eyebrows became golden, and his irises turned green. Goku had transformed into a Super Saiyan.
Future Trunks said, "Great, just like that. Now, I'll transform into a Super Saiyan as well."
"What?" Goku was surprised by Future Trunks' words. He never expected that someone other than him and John Doe could transform into a Super Saiyan.
