In most cases with the movies, the script writers used their marvelous techniques to write up an original story, based on my original work. The original work develops in such a way that it makes it difficult to come up with side-stories, so I think they really did a good job.
I was very busy during serialization, so I couldn’t really help them out, but every once in a while the producer would ask me to design an original enemy character for the movies, so that was the only time that I’d collaborate with them a little bit. But that sure was hard… Even though I had all these strong-looking characters appearing in the manga, and was already at my limit material-wise, I still had to think up even stronger designs… Really, they’re all such a strong-looking bunch that it raises my blood pressure.
Still, this allowed them to make these amazing movies that are so powerful and effective, so what am I complaining about?
As the creator of Dragon Ball, I’m thoroughly made aware of what a happy manga it is, blessed by its fans and staff.
