Vegeta is shown to be exceptionally vain and egotistical. His most defining trait is his rivalry with Goku and his obsession to surpass him in power. Vegeta is recognized as one of the most reliable and strongest warriors known, and this allows him to not only reconcile with all the Z Fighters but to accept them as genuine comrades. Vegeta still carries his Saiyan pride, especially since he's the prince of the Saiyans who are the ultimate warrior race.
