Anime is known for being over the top. This is not true, but only because Goku blew up said 'top' by sneezing on it, thus ensuring that there will never be a top to be over.
Seeing as how one of the roots of Japanese pop culture is the Kabuki theater, which is characterized by embodying events and emotions in as big a way as humanly possible, it only makes sense that anime continues that trend of big emotion, big stakes, and even bigger spectacle.
Anime is famous for its characters being able to be thrown through walls, punched hard enough to put a crater in the building behind them, and then be blasted into orbit...only to come back down, barely hurt to do the same to their opponent. But even with this insane medium, some are stronger than others.
If you were to compare all anime characters - not just protagonists - to each other as if they inhabited the same universe, who would stand above them all as the most powerful of the bunch? Since Jump Force turned out to be a screaming garbage fire, we can't actually perform this comparison in concrete practice, so this will have to do!
These anime characters go from skilled fighters to wielders of the power cosmic itself. And the majority of them are teenagers. So that's reassuring.
