Vegeta

Vegeta is a boss and one of the playable characters in Dragon Ball Z: Kakarot.

Saiyan Saga
Prince of the warrior race of Saiyans and a super elite warrior. He and Nappa made their way across the universe conquering planets, and after learning of the Dragon Balls from Raditz, the pair ventured to Earth. Vegeta transformed himself into a great ape in his fight Goku on Earth, which no longer had a moon off of which enough sunlight could be reflected.

Frieza Saga
Tired of being under Frieza's thumb, Vegeta scoured Planet Namek in the hopes of finding the Dragon Balls before the evil emperor. Vegeta's battle suit suffered a great deal of damage after the fight with the Ginyu Force, but he was forced to replace it with an older model due to limited quantities of the newer models. After changing his battle suit, Vegeta saw fit to provide both Gohan and Krillin with suits as well, knowning that the two should prove useful in the fight with Frieza. Vegeta opted to not use the Dragon Balls to wish for immortality after the fight with Frieza, instead choosing to abandon his desire for universal domination in favor of seeking power in more natural ways, with the end goal being maintain his pride and ultimately surpass Kakarot.

Cell Saga
After the fight on Namek, Vegeta became accustomed to fighting with the older style of armor, which had no shoulder or hip guards. Vegeta felt that, though the guards did not hinder movement, they added unnecessary weight and slowed him down in combat. The armor he wears on Earth is a creation of Bulma's, something she developed after analyzing Frieza Force armor.

It was during his solitary training in prepartion for the androids arrival that Vegeta was finally able to achieve the Super Saiyan transformation. His overwhelming desire to get stronger and consequent frustration with his inability to do so were the catalyst that awakened the necessary power within him. Thanks to the year of training he underwent in the Hyperbolic Time Chamber, Vegeta was able to push the Super Saiyan transformation even further. Though he had struggled to handle Android 18 before, Vegeta was now able to overwhelm the much more powerful Cell in his second form.

Majin Buu Saga
In the seven peaceful years after Goku's death, Vegeta continued to train and finally achieved the Super Saiyan 2 transformation Gohan first displayed in the Cell Games. Though eager to test his newfound power on Goku, Vegeta would have to wait and do so via less-than-desirable means. Vegeta wore his training outfit during normal training sessions and the World Tournament. Its lack of armor makes it easy to move in. Eager to fight Goku in the tournament, Vegeta had no idea he would soon be caught up in a series of events that would culminate in a battle for the universe.

With Goku only back for one day, Vegeta knew this may be his only chance to prove himself the superior Salyan. He thus allowed himself to be mind controlled by Babidi in exchange for a great deal of power. His fight with Goku ultimately led to the revival of Majin Buu and also to a growing sense of doubt within himself. After sacrificing himself Vegeta was temporarily revived by King Yemma in order to help Goku fight Majin Buu. It was during the fight in the Land of the Kais that Vegeta finally acknowledged Goku's superior strength and did what he could to buy him enough time to form a Spirit Bomb.
