Vegito

Vegito is the result of the fusion of Goku and Vegeta who fused by the use of the Potara earrings. His voice is a dual voice that contains both Goku's and Vegeta's voices. Vegito is regarded most for his immense power and speed, and is the most powerful character in the entire Dragon Ball Z series which was confirmed by Akira Toriyama. His Fusion dance counterpart is Gogeta. He makes a appearence in the Buu saga and is never seen again.

Appearance and personality
Vegito is a mixture of both Goku and Vegeta's characteristics. He is about the same height as Goku, and his personality is a mix of the two Saiyans. He exhibits Vegeta's cockiness and inclination for taunting others, and playing around with his enemies, wanting them to suffer, but is not as serious, having inherited Goku's easygoing, cheerful nature. Having easily toying his opponents. He possesses both Vegeta's strategic mind and Goku's combat intelligence, making him that much more efficient. Goku's benevolence and concern for others is also prevalent in his character (he ultimately used his cocky attitude to fool Buu into absorbing him, which gave him the chance he needed to save Buu's absorbed victims). Being a whole new being, he refers to his counterparts as separate people as they would address each other. However, it is interesting to note that in the Japanese version, Vegito ("Vegetto") mentions "Kakarotto" and not "Goku", while in the movie Dragon Ball Z: Fusion Reborn, Gogeta refers to Goku, suggesting a predominant base of Vegeta, despite having an equally balanced and truly fused personality.

Vegito's hair is more inclined toward Vegeta since it firmly stands upwards and is very dark brown in color. However, he has two bangs sticking out like a downward "V" shape, a trait caught from Goku. When he transforms into a Super Saiyan, he looks almost exactly like Goku. Vegito wears two earrings as result from the Potara fusion, and wears an inverted version of Goku's outfit. The inversion is caused by adopting the color of Vegeta's outfit for the external wear, and using the orange of Goku's outfit for the undershirt. Finally, he wears white gloves and boots in the same style as Vegeta. He is very similar to Gogeta, who is another fusion of Goku and Vegeta seen in Fusion Reborn and Dragon Ball GT.
