>>95037722Iron man has a suit like Kamen Rider. Captain America is tied to nationalism of a foreign power; you'd have to be a turbo westaboo to like it.
I doubt the Japs would like teen titans. They don't like Western attempts to do anime style because frankly the West's attempts are cringey and stupid.

One of the big divides between Jap heroes and Western heroes is that Western heroes start with a fixed power level and it more or less remains that way, it really only fluctuates from writer to writer. Japanese super heros have an increasingly power level. They get a new, better mecha, unlock a new ability, get a better trasnformation, etc.
This means that they need a constant string of new bad guys who also have higher power levels. If there is a recurring villain he's either already at max power but doesn't confront the hero directly until the final season or the recurring villain also gets power ups. The rest of the villains get killed off because they are no longer an appropriate challenge, something that is very alien to super heroes.
