Goku saiyan had Saiyan Planet as birth place. When he was born, he had a fighting power only five units. this made his father, Badock, being disappointed because he was a top level fighter of Saiyan star. Goky’s father was inferior than only Vegeta, the king of Saiyan planet. So, Goky’s father had an idea to send Goku to another star to keep him safe from danger and hoped him to rule over the star in the future. According to the story, there’s only two persons, Badock and Radiz, who were his bloodline.

Goku saiyan had a general character like other Saiyan fighters, that was to love fighting. He was happy when he had a chance to fight with the stronger fighters. Saiyan members love eating, so they can eat much food as can be seen from Goku, Gohan, Trunk, and Vegeta. In fighting aspect, Saiyan people had a special characteristic which was the ability to transform themselves to be giant monkey. The giant monkey had fighting power 10 times more than normal Saiyan people. The limitation was that they could transform to be the gient monkeys only in the full moon night and only Vegita could create the moon by himself.

Goku saiyan was the first one who was the legendary fighter which could be born in every 1,000 years. The legendary figheter could be also called “Super saiyan”. When Goku could be super saiyan, his power and speed increased. But later there were so many Saiyan fighters who could change to be super saiyan.

Fighters who have Saiyan blood are Goku, Gohan, Goten, Trunk, Vegeta, and Vegeta’s brother who just appeared in the special episode of Dragonball.

If you ask what character in Dragonball is the everlasting enemies, you’ll get the answer as goku and Vegeta.They were always enemies but unbelievably later they stay at the same side and cooperating each other to fight with other new enemies. They first met in the earth after Radiz (Goku’s elder brother) had killed.

Firstly, Goku’s power was much less than Vegeta’s but he could win over Vegeta because of his freinds. After that, Goku’s power is different from the begining. His power has increased a lot and has it more than Vegeta because he practices very hard. In the fight with a competent enemy - Frieza, he can transform himself to be super saiyan, making him have even more power than Vegeta.

Goku and Vegeta have same level of power again in Cyborg war as Vegeta can also transform himself to become super saiyan. In the fight with Cells and Majin Buu, Goku’s power has been over Vegeta. Moreover, Goku can transform to be SSJ3. That makes Vegeta give up and accept in Goku’s ability and accept that he’s number one of Sayan.

In DragonballGT, Goku can transform to be SSJ4 while Vegeta can be only SSJ2. It shows that Vegeta’s power is much far away from Goky’s. Then, Vegeta has a hope to become number one of Saiyan because he can transform to be SSJ4 by the help of Bluma. At the end of the story, both Goku and Vegeta have power of SSJ4.

There are two fighting wars between Goku and Vegeta in the earth. Goku won for the first time and for second time, the result is “even” in Majin Buu fight.
