We could do that. What if we organized them by saga? (Saiyn, Namek, Cell, Buu, etc). Any thoughts about that? If we did it this way, we could talk about characters in the context of each specific saga and readers won't learn any more than they want to about how things turn out.
You could have one section for the core cast, and separate sections for each saga to discuss the villians and other characters exclusive to that arc.
I would suggest that it's not the medium, but the quality of perception and expression, that determines the significance of art. But what would a cartoonist know? -Bill Watterson
