Goku & Vegeta

Prince Vegeta, is the prince of the fallen Saiyan race and arch-rival to Goku. He is the eldest son of King Vegeta, the older brother of Tarble, the husband of Bulma, the father of Trunks. Alongside Goku, Gohan, and Piccolo, he is easily one of the most prominent characters in the Dragon Ball series, receiving a significant amount of character development since introduction.

Regal, egotistical and full of pride, Vegeta was once a ruthless, cold-blooded warrior and outright killer, he later abandons his role in the planet trade run by Frieza, 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 to defeat and surpass Goku in power. His character evolves from villain to anti-hero to protagonist through the course of the series.
