From the moment he was born, he knew that he was to become a super Saiyan.

Heritage expected it of him, the power measuring instruments confirmed it, and the results of his combats proved it--Vegeta was a warrior of superior class among the Saiyan.

Before Vegeta, the strongest Saiyan was his father, and when Vegeta's power exceeded that of his father while he was still a kid, his arrogance grew, further instilling his belief that he would be the strongest, giving him the right to look down on everyone else, because on Planet Vegeta, power was everything.

And then there were Freeza and his henchmen. So even though Vegeta knew that he was the strongest of the Saiyan, he also knew that there were other races that were more powerful. However, the Saiyan race was the ultimate warrior race. Vegeta knew that with time, he would eventually surpass Freeza's henchmen, and perhaps even become the mysterious Densetsu no Super Saiyan, the one who legends foretold as the strongest in the universe, the one who even Freeza would be no match for.

Vegeta's dreams were crushed when he suffered defeat at the hands of an inferior warrior, Kakarot; or as his earthling friends call him, Goku. What was even more devastating was that this Kakarot. This Goku, displayed power that far surpassed even the royal prince himself while fighting against Freeza's hired goons on Planet Namek. It was devastating to see a mere low-class warrior fight opponents that gave Vegeta such a hard time. "Could he be... the Super Saiyan foretold in the legends? It can't be true! The legend is just a myth! ...and even if it were true, I should be the only one who becomes Super Saiyan!"

And on earth, his fear became a reality. Kakarot's son has confirmed that Kakarot indeed has become a Super Saiyan, and has even defeated Freeza, who Vegeta knew, at the time, he was no match for. Vegeta had lost his life while fighting Freeza, and had been resurrected by the Dragon Balls.

A year after the battle on Namek, Freeza shows up on earth, and while Vegeta has been training all this time, hoping that he would be able to defeat the Super Saiyan, he knew that his training had not helped enough for him to take on Freeza. Vegeta expected doom. That's when the strange boy arrived. He killed Freeza, his father, and their henchmen in a matter of moments. From what Kakarot’s son has seen of a Super Saiyan, it was confirmed that this boy was also a Super Saiyan.

Goku came back to earth, talked with the boy privately, and both displayed their power as Super Saiyan. At this point, Vegeta knew just how strong a Super Saiyan was, and what they looked like. With a goal in mind, Vegeta sets out to surpass the power of a Super Saiyan through intensive training. Now more than ever, because the boy is from the future, and he tells a tale which involves cyborgs much more powerful than any Super Saiyan. Vegeta cared for no one; he only had one goal--to become the strongest.

Somehow during all this, he and Bulma got together for at least a short while. It remains a mystery what the two were thinking at the time. All we know is that Bulma had once again had a big disagreement with Yamcha, primarily for his unfaithfulness, and somehow both Bulma and Vegeta felt each other's loneliness. Nine months later, Bulma had a son; she named him "Trunks."

As Vegeta trained in the adverse conditions he placed upon himself, he realized that he had reached his maximum, and it was nowhere close to that of a Super Saiyan. His training has proven futile. Vegeta was infuriated at himself, how could a genius fighter such as himself be outclassed by someone who belonged among the fighters of a lower class? This rage at himself triggered his transformation. Suddenly, he had also become a Super Saiyan. With this transformation, he suddenly understood what it meant to be a Super Saiyan, and what was required to become.

Since they had both become Super Saiyans, it would only be natural for the genius fighter to be stronger than the low-class fighter. Assuring himself thus, Vegeta went on the fight the cyborgs, and once again suffered defeat. He once again looked for the answers himself, and realized that he was bound by the limits of a Super Saiyan. He needed to find a way to go beyond a simple Super Saiyan transformation. With the introduction of Cell, this was more important than ever.

During the battle with Cell and Cell Junior, Vegeta came to terms with reality. As much as he hated to admit it, Kakarot somehow always seemed to come out on top. Vegeta finally accepts what he had known all along, that Kakarot would always stay one step ahead. However, this would seem like nothing to what he is about to face. The death of his son, Trunks.

Cell had teleported back, and the first person he killed was Trunks. The prince snapped when he witnessed his son's death right before his eyes.. while he was helpless to stop it. Heavy bombardment of ki-blasts were sent to his son's murderer as retaliation, which also proved to be in vain. In the end, Kakarot and his son finished the job that Vegeta couldn't.

A repeat of the same thing was seen again with the next enemy, Majin Boo. Finally Vegeta learns to let go of his arrogance, and to care for the people around him. He learned to love, and luckily, it was not too late.

Technique - When Vegeta arrives on Earth, he can't yet reach SSJ state. Actually, both Goku and Future Trunks accomplish this before him (in order of appearance, not chronologically). He only reaches this superior fighting ability when training for the conflict against Dr. Gero's artificial humans. He reaches SSJ2 during the 7 years period after Cell's death, during which he practises with his son, Trunks, although we only witness this in the Goku vs. Vegeta battle upon the start of the Boo era. During the first attack on Earth, Vegeta shows that he had learnt how to control the transformation into Saiyan monster. He was almost unbeatable in this form and he would have destroyed the planet and all the fighters, if his tail hadn't been cut, which took the metamorphosis power away from him. He tried to do the same to Gohan before his (Gohan’s) transformation, but he was too late and he had to do it afterwards. He could also concentrate (relatively) large amounts of energy upon himself. He could shake the land around him and raise large pieces of rock and earth. This is something that would be common from then on, but it was quite a novelty at that time. Vegeta 's trademark technique is the Big Bang Attack. It is very powerful and consists of a large concentration of energy in the palm of one hand (eg. the Kame Hame Ha technique), with the correspondent arm stretched, after an initial pointing gesture. Next, well, he shoots a devastating energy ball. I thinks Vegeta 's most feared technique, and one in which he is a master since the beginning, is his stone-solid self-confidence, will power and determination. He is a great warrior mostly because of this.
