DBSB: Saiyan Blood

In the far future where no one on Earth remembers the great deeds done by the Z fighters long ago, where no one remembers the threats that roam through the universe. Where Goku and the rest have become legends, mankind has now only started populating the solar system, with the colonies on Mars, the mining stations on the asteroid belt and the cultivation stations on Mercury.
Now it had to happen…
The deeds of Gohan, Vegeta, Goku … have, although not on Earth, become twisted over time and there are some that head for the legendary planet that creates the strongest fighters in the universe.

It was a bright day as Koa was walking down the street, a few hover cars passed by while he was walking past a 3dtv shop. He stopped and paused, while he looked at the screens, becoming entranced in them he saw the darkness of space surrounding him, he could look back or forward every stars were forming or dying. A voice came from somewhere describing what he saw. He passes here every morning, dreaming of going into space. The problem was he couldn't; only if you had an astro card, you could go to one of the planets. But that took long and hard to get it, not to mention that it's expensive. He closed his eyes and when he opened them the stars were gone. He continued walking, looking to the sky, at the sun, which was now a yellow circle with 5 small bumps sticking out. You couldn't really see them but if you looked carefully you could more or less make them out. The bumps moved sometimes, to remain directed at Earth so that they could still send power towards it. Sure it was cheep power yet some people still complain that they preferred the sun to be perfectly rounded, though they're hardly visible. As he walked along suddenly some thing seemed to block one of the bumps. At first Koa thought that it was just moving but then part of the sun got covered and it started getting bigger and bigger. When it was almost half way through it stopped and it seemed moving away from the sun. As it cleared the sun Koa could start making it out, it was definitely metallic and round, unlike any other spaceship he'd ever seen.

The spaceship spewed out high concentrations of fire landing itself safely on the 3dtv shop Koa walked by earlier. The shop broke down and the ship came down in a loud bang. Koa ran back and glanced over the shining metal of the ship. Suddenly a sound that sounded a lot like air pumping out was combined with the opening of a door. Three figures stepped out, one of which with long robes and what seemed to be jewellery. The two other ones fired small laser blasts out of rifles they had in their hands. It exploded the buildings on the other side of the street. Now 5 more had stepped out of the probably cramped craft. Koa became even more surprised as 2 more stepped out. By now everyone had cleared the streets and army tanks were rolling around the city. Koa still stood there and was approached by three of the mysterious beings. They dropped their weapons and part of their clothing. The clothing made cracks in the badly shaped street and the three beings suddenly appeared behind Koa. He couldn't believe their speed. He suddenly felt a hard punch in his back and fell face down on the ground. He grappled himself up and stood amazed at the aliens. Now the one in robes came forward and spoke perfect English.
Alien: 'Leave him, take him into the ship for questioning'
Other alien: 'Yes, sir'
The 3 aliens dragged him into the small ship and closed the door. Koa looked up and saw an amazing room inside the ship. It must have been at least as big as the whole block. The room was silent; he couldn't hear anything that happened outside. By the time he thought this out he was strapped to a chair and was gazed upon by the extra-terrestrials.
