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 when he killed the evil King piccolo, but no matter what, he wanted to be stronger to 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 there.
Still he becomes serious when the enemy had evil intentions or the idea to destroy the world he knew passed their minds, he didn't like getting to that extremes, it only happen one time with King Piccolo and he was younger at the time, he had a 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 the King Vegeta sent him to earth when he had thirteen years old.
Goku remembers the day he met him as 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 even the need to want to control the earth, but thanks to Goku, after he beat him fair and square, Vegeta with the really big pride he has, decided to stay on this planet, so he can beat him first and then rule the earth, months passed until he began to gain sincere interest of 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 the time, he could say that Vegeta lost his initial interest in dominating the earth, he will never admit it of course, that and the sparring both of them had time to time make him change his way of thinking, but his snarky and angry attitude went unchanged calling Krillin and the other 'insects' or 'scum' since they were only weak humans, but all of them knew it was more of strange nickname for 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 a Arctic place and how this could bring problems like the one when he and Vegeta encountered when they fought King piccolo reincarnation which was way more powerful that kami anticipated thanks to a 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 reincarnation, Goku didn't want to see a murder spree again and Vegeta, he wanted to be stronger and to know this Piccolo, that was enough reason for him to say yes.
They both beat him, Vegeta wanted to kill him but Goku didn't, so they let him go for now 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 to catch unnecessarily attention until it was really necessarily.
Goku began to feel enthusiasm after hearing all that, he wanted to beat any opponent stronger than him, he missed that feeling and with that he said goodbye to Kami, making sure 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 seventeen years old" Kami sighed.
