Man I thought that this movie was suffering GT syndrome since everybody but Goku is useless but if that spoiler it's true....
"Do you write things down when you come up with those ideas and background stories?
Akira Toriyama: No, I don’t, that’s why I forget a lot. If I don’t forget those ideas, then I won’t need to come up with new ideas. Do you remember Super Saiyan 3?
Yes, I remember, Goku grows his hair long.
Akira Toriyama: That’s right, but actually I forgot about it and I thought that was Super Saiyan 2, even though I created those characters"
Wow. Guess Toriyama really stopped caring back in the Buu saga.
Also this must have been where Toriyama got the idea for Super Saiyan God
