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. He would later repeatedly fight alongside Universe 7’s most powerful warriors in order to protect Earth and his family, as well as to surpass Goku in power.
Vegeta’s character development is the most praised and one of the biggest in the series. He started off serving as the main antagonist of the Vegeta Saga, but then as an anti-heroic tritagonist throughout the rest of Dragon Ball Z. After the Majin Buu Saga Vegeta would evolve into a hero as the main deuteragonist/secondary protagonist of the sequel series, Dragon Ball Super.
