We all know that there is a Goku Jr. special, but there was a Vegeta Jr. special too.
I have this book called "Akira Toriyama, Take 2". It has info on every manga he made, and every movie made by TOEI based on his manga. In the DBGT section it says that there was a Vegeta Jr. special made, but when they were going to show it, the showed a Ruroni Kenshin special instead

. And they never showed it again. I hope that Funimation gets a hold of it and make a copy. It's true.
