The Saiyans were also increasingly the most popular part of the franchise. Now whether that's because the human characters weren't around for a year and change during the initial run I don't know. But just looking at the box office revenue for the DBZ era movies, Saiyans were bringing in more and more money with each subsequent film. Extreme Battle! The Three Great Super Saiyans brought in almost two times as much as The World's Strongest. And Broly managed even more than that. So, I think that's as good an answer as any. Humans were phased out because Saiyans had a proven track record among fans far eclipsing the numbers TOEI were used to with their earlier DB movies.Lionel wrote: ↑Tue Jan 21, 2020 10:44 pmThere really isn't much of a sensible answer to that question outside of deferring to the original authorial source, i.e Toriyama. After a certain point he just seemed to hold no interest in maintaining the legitimacy of the humans. His mind may have come to the conclusion that it was easier and reputationally more practical to emphasise the Saiyans, sans Piccolo early on, rather than conceive of a way to keep the humans in the running.
What was their maximum power level at the time? We know they could consciously restrict their strength dating back to the first tournament. It's unlikely they were projecting their full strength at precisely that moment. Who's to say they didn't surpass the benchmark of the 23rd tournament or at least came close to it?
Anyway, sorry for the tangent. I know this line of that isn't exactly an "in story" explanation for anything
