Ready for this one? Because this answer is going to knock your socks off. Probably one of THE best answers to this question you'll ever see...
Japan finishes their Japanese tokusatsu hero version of Spider-Man.
Immediately after, instead of losing touch, Toei and Marvel manage to work out a deal.
They bring Japanese Spider-Man over to America for Television broadcast, dubbed and mostly uncut. ***BUT!!!!*** As a backup plan (because Marvel knows how much the fans prefer Peter Parker), they also bring over Go-Ranger and the original Kamen Rider. They air that on television as well, again dubbed and mostly uncut. And these are very good quality dubs.
It reaches overnight success.
Marvel changes the way we see and think about superheroes by working with international sources and inspirations.
As a result, Marvel brings us more and more Super Sentai and Kamen Rider over the years.
Eventually, with the rise of DVDs, we get the fully uncut versions of the TV shows with a Dual Audio and Subtitles option.
Power Rangers? Masked Rider? Never happened. America, and the rest of the world, NEVER goes through the Adaption process.
The heroes of Japan become our heroes as well, we see them making crossover appearances in Marvel comics, Hollywood sometimes makes high-budget Super Sentai/Kamen Rider tribute/reboot movies on par with their current Avengers movies.
The world is a better place, and there is a lot less reasons for fansubs.
