Vegeta

Vegeta (ベジータ, Bejīta), or Prince Vegeta, is a fictional character in the Dragon Ball  manga series created by Akira Toriyama. Vegeta first appears in chapter #204 Goodbye Son Goku, published in Weekly Shōnen Jump magazine on December 19, 1988, seeking the wish-granting Dragon Balls to gain immortality.

As prince of the Saiyans, an extraterrestrial  race of warriors that the series' protagonist Son Goku also belongs to, Vegeta is extremely vain, believing he is the strongest and becoming obsessed with surpassing Goku. He later reluctantly unites with the heroes to thwart greater threats to the universe, becoming an antihero, while remaining a rival to Goku. Vegeta's character, particularly his personality, has been well received.

Regal, egotistical and full of pride, Vegeta was once a ruthless, cold-blooded warrior and outright killer, but later abandons his role in the Frieza Force, instead opting to remain and live on Earth, fighting alongside the Z Fighters; all the while striving to become the universe's most powerful warrior, specifically with the mission to defeat and surpass Goku in power. His character evolves from villain, to anti-hero, to protagonist through the course of the series.
