Vegeta Jr.  

Vegeta Jr., who descends from Vegeta, was seen once at the end of Dragon Ball GT. He resembles Vegeta in both his name and demeanor. In the Tenka-ichi Budokai tournament, he faces off against Son Goku Jr., the great-great grandson of Son Goku. When they first meet, Vegeta Jr. asks Goku Jr. if those are the clothes he's wearing. He proves to be just like Vegeta in his attitude and fighting style. The two competitors are evenly matched. When Vegeta Jr. sees Goku Jr. transform into Super Saiyan, he says "I didn't know we both could go blonde." This suggests that they may not be familiar with the actual name for this form. It is unclear whether Vegeta Jr. is descended from Trunks or Bra, as there is little evidence to support either claim. However, based on his mother's hair color and Goku Jr.'s ignorance of the Super Saiyan name, it seems more logical that he is Bra's grandson rather than Trunks'.
