The reason why he didn't get to keep his name is probably down to Vince's long-established hatred for the title "Junior"
I thought he was DiBiase Jr at the beginning then they took it away after a little while. Especially cause there were points where he and his dad were on TV together.No actually his official ring name didn't have the Jr. He was just "Ted DiBiase" but fans always made the distinction...bc ya know you kinda have to
Chavo never had it either. At least in WWE. I think he had it in WCW
