Ji backed away in terror. "He just killed Lord Freeza in a instant!"
"That was marvelous." said King Cold, "I am very impressed by your strength. I want you to become my new children? So many planets to conquer and Rule."
"Not interested." said Future Gohan as Trunks landed on the ground.
"We are not interested in ruling the Galaxy." said Trunks, "but perhaps you can help us."
"What?" said Cold.
"What my pupil means is that there is a greater Evil coming and we will need all the help we can get." said Future Gohan, "I can sense that there is some good in you unlike your son. Why don't you join us?"
King Cold turned to Chi and Ji. "There are a lot stronger than we are." He said, "there also is no point of being the ruler of the Galaxy if there isn't going to be a Galaxy left."
"Yes your majesty." said Chi, "perhaps we should take their offer."
"They could kill as easily and they would have by now if they really wanted to. It would be wise to work with them." said Ji.
King Cold turned back to future Gohan and Trunks. "We can help any way that we can. If you really want to kill us I'm sure you would have done that by now but you have spared us. For that we are in your debt." King Cold and his little speech by getting onto one knee in a show of respect as Ji and Chi did the same.
Future Gohan smiled as he turned to face little Gohan. "You can go back and tell the others that everything is okay. Father will be arriving in 3 hours."
Little Gohan nodded.
"Don't feel bad Gohan." said Trunks, "You have a lot of Courage for someone your age. Whatever you do do not stop your training. Your counterpart did warn me that your mother can be crazy about education sometimes, I always stay strong. The future will need you."
"Thank you sir," said Little Gohan, "I didn't catch your name."
"Trunks. I am a half saiyan like you. But that's all I can tell you, if I give you too much information that might change the future and and prevent my conception."
"I understand." said Little Gohan.
Three hours later…
"Okay Mr Future!" Said Yamcha, "those three hours are about up. Where is Goku?"
"Same old Yamcha." Future Gohan laughed, "I really miss that sarcastic attitude of yours."
Vegeta have been sitting alone a few feet away from the others when he noticed that Trunks was staring at him.
"What's the matter?! Ever seen pink before?!"
Trunks turned away from Vegeta has future Gohan laughed.
"Are you sure this is the place?" asked Trunks.
"573 point 18220." Set a future Gohan as he looked at his watch. "It's got to be in this general area."
"Don't they look alike?" Bulma whisper to Krillin.
"Who do you mean?"
"I mean Vegeta and that mysterious kid who calls himself Trunks. They sort of feel very similar. I'll bet he's Vegeta's son from the future." Bulma giggled.
Little Gohan gasped. "Dad! It's his Ki. I can sense it!"
"Someone is coming." said Tien, "Someone very strong."
"Is that your father?" Trunks asked Future Gohan, "Wow! He could have defeated Frieza easily without our help."
"I told you." said Future Gohan, "My father has a certain feeling about him. Just being in his presence can make someone feel secure."
Goku's space pod landed in the ground, creating a gigantic crater in the earth it smashed into. The entire crowd gathered nearby to see Goku emerge.
Finally the door opened and Goku hopped out.
"Is he the one who defeated my son?" asked King Cold.
"Yes." said future Gohan, "That's him. My dad!"
"Uh, Hey guys." said Goku, "I was able to sense Freeza here a moment ago, but now I can't sense him at all. What happened?"
"That was me." said Trunks with a bow, "It's an honor to meet you Goku-san."
Goku looked over at King Cold and his friends. "Bad energy. Evil."
"That is King cold, Freeza's father. I spared him and the other two members of Freeza's army." said Future Gohan, "there is something very big coming up and I thought we could use their help."
"Something big?" asked Goku.
"Yes." said Trunks, "is it okay if we talk to you in private for a moment?"
Before Goku could answer, King Cold, overhearing the conversation approached.
"I am grateful for my life being spared, and I'm willing to help out in this cause that this young man has promised is worthy of my time. I don't see a point in living if there's not going to be a galaxy left to conquer afterward, after all. This is Ji and Chi. They are the only two remaining members of my Army. We will help any way that we can."
Goku nodded, "you do know that I am much stronger than all three of you combined and that I could take all of you out easily. You don't strike me as someone who is stupid unlike your son. I don't think that you will try anyting."
Goku turned back to Future Gohan and Trunks. "All right, I will speak to the two of you in private if you have something very important to tell."
The three of them flew away from the rest of the group several feet so they could talk.
"I know you think you made a questionable decision by sparing King cold," said Goku, "but I trust that you made a good judgement. After all you are my son and I trust your judgement."
Future Gohan stood there speechless.
"What?" said Trunks.
"Father I look nothing like I did when I was a child. I am bigger and stronger now. How did you recognize me?"
"You're my son, and I can tell that without a doubt by looking you in the eyes. I knew it was you the second I laid eyes on. But I am wondering how you can be here." said Goku, "I know I'm not the smartest person in the world but even I can see that having two Gohans here doesn't seem to make a lot of sense. Also what happened to your arm?"
"Well," said future Gohan, "I really am your son 20 years in the future. My good friend Trunks and I have traveled here to save your life and the future."
"My life?" asked Goku, "what happened to me?"
"You picked up a hard virus which eventually killed you, and then a little while after your death; 4 androids appeared and started to create Havoc all over the world. Killing so many innocent people. They had killed off the others one by one and I had escaped with my life. At some point two of the stronger Androids had killed the two weaker ones."
"And what about your friend here?" asked Goku.
"I am a half Saiyan like Gohan." Sais Trunks, "I am the son of Vegeta and Bulma."
"What!? Bulma and Vegeta!" Goku exclaimed in disbelief at what Trunks just told him. "Wow that's unbelievable."
"In 3 years on May 12th at 10 a.m, 2 androids with incredible strength created by Dr Gero of the Red Ribbon army are going to attack an island 9 miles southwest of south city and soon after decimate most of the planet. Gohan and I are all that stands between them and what's left of the world."
"if only I was there to fight the Androids," said Goku, "if only I would get that chance."
"Don't worry dad. You will this time." Gohan said handing his father a medicine bottle. "This is the cure to the heart virus. Just take this when you start to feel sick."
"Thanks Gohan." Goku said smiling at his son.
"No problem dad." Gohan said smiling back. "Well, We better get going. If all goes as planned we'll see you in a month for us and 3 years for you."
As future Gohan and trunks went back to their time machine, young Gohan approached.
"Pardon me," little Gohan says to Trunks, "I think I just figured out who you are."
Trunks gasped. "You have?"
'This could change the future. It may even prevent my conception.'
"Yes. Your eyes and eyebrows gave you away. You're Vegeta's child, aren't you?"
"Yes." Trunks said.
"Don't worry," said Little Gohan, "I won't tell. I wouldn't want to prevent you from being born."
"Thanks." Said Trunks as he and future Gohan climbed back into the time machine.
Note: I am skipping a head to the hyperbolic time chamber since all of the other events up until that point are the same as they are in the anime. Vegeta turns super Saiyan and destroys android 19, 17 and 18 kill Gero; release 16 and etc.
