>>14670783I'm usually not fond of the "new bad" mentality but mainstream battle shonen's one of the few genres that took an objective nosedive around the late 90s/early 2000s and never really recovered.
There's exceptions like Gash Bell but for the most part battle shonen's mostly unbearable.
A lot of the best post-2000s manga/anime that follow the "battle shonen formula" are parodies or subversions that aren't really aimed at the battle shonen audience.
