Chapter 1:

The Saiyan Fighter

Goku wasn't a normal teenager and after some years passed he noticed it; he was way stronger than the boys of his age and he even had a tail before an accident made him lose it permanently. To his friend's relief.

He did his best to protect the place where he was raised when he fought with the red ribbon army and even went far enough to kill the evil King Piccolo, but no matter what, he wanted to be stronger so he could defend his friends and because he really liked fighting. Something in his blood clicked when he had a strong enemy; showing even enthusiasm when the prospect of a battle was in sight.

Still, he becomes serious when the enemy has evil intentions or the idea to destroy the world he knew passed their minds, he didn't like getting to those extremes. It only happened one time with King Piccolo and he was younger at the time, besides that he was known for his forgiving nature.

Something that his proclaimed rival Vegeta, hated.

Both of them still had rocky times and that was thanks to Vegeta's side since Goku didn't mind him that much. He even considered him his best friend in some weird way, after all, he was the one who told him why he was different and about their race, the one where Vegeta was a prince before King Vegeta sent him to earth when he was thirteen years old.

Goku remembers clearly the day when he met him like if it was yesterday and not three years ago; he was a strong kid taller than him at the time, he had a really hard attitude with a little bit of bloodlust and the need to control the earth, but thanks to Goku, after he beat him fair and square and with the help of Vegeta's big pride, he decided to stay on this planet, so he could beat him first and then rule the earth. Months passed until he began to gain sincere interest in the planet, he told him about how people were so careless and kind, a trait that could get someone killed off in their home planet.

After knowing him for quite some time, he could say now that Vegeta lost his initial interest in dominating the earth. He will never admit it of course. His travels and the sparring they both had from time to time made him change his way of thinking, but his snarky and angry attitude went unchanged. He still called Krillin and the other 'insects' or 'scum' since they were only weak humans in his eyes, but all of them knew it was more of a strange nickname coming from him so they didn't care too much.

There were Pacific days, of course, the ones when he could visit his late grampa's house or days where he could visit Kame House, so he and Master Roshi could have a short talk about the days where Krillin and he were his students.

And if Vegeta was around and not exploring someplace, they could spare to their heart content, since they couldn't hold back if the fight was between them.

It was until Kami himself called him to the lookout and told him about the strange black energy that began to appear in an Arctic place and how this could bring problems like the one he and Vegeta encountered when they fought King piccolo's reincarnation which was way more powerful that kami anticipated thanks to black energy that was way too similar to this one. He agreed to train for three months, it could be way easier than when he and Vegeta trained three years before when they prepared themselves for the worse for King Piccolo's reincarnation. Goku didn't want to see a murder spree again and for Vegeta, he just wanted to be stronger and to know this Piccolo, those were enough reasons for him to say yes.

They both beat him, Vegeta wanted to kill him but Goku didn't, so they let him go with a stern warning, for now.

Kami told him that his predictions were linked with The World Tournament of Martial arts and he made Goku promise to keep a vigilant eye on it and to be prudent since the energy could take any form or even possess a body of a human, but he still needed to be careful. He didn't want him to catch unnecessary attention until it was really necessary.

Goku began to feel enthusiasm after hearing all that, he wanted to beat any opponent that was stronger than him. He missed that feeling and with that in mind, he said goodbye to Kami, telling him that he will come tomorrow to begin his training.

"I can't still believe how strong this young man is" Mister Popo, the loyal Assistant of Kami was surprised.

"Yeah, and he only is sixteen years old" Kami sighed.
