Vegeta Jr. is the Human/Android and Saiyan hybrid son of Vegeta and Android 18. He is also Goku Jr.'s rival and the husband of Yamcha and Launch's daughter. Vegeta Jr. was born in Age 766 to Vegeta and Android 18, thus making him a Saiyan/Human/Android hybrid.
Vegeta Jr.'s hair color is a combination of his parents'. He has his father's eye shape, facial features and tanned skin, and his hair turns blond and eyes turn (pupil-less) green when he becomes a Super Saiyan.
Vegeta Jr. is shown to have a combination of both of his parents' personalities: cocky and proud like his father, and cool and confident like his mother. He refuses to respect someone he does not like, another trait he shares with his father. This is shown when he disrespects Goku when they first meet, and for a long time after, as Vegeta Jr. believes he is not as strong as his father, and nowhere near as reliable.
