In a way, I feel as though all Shonen authors are "power-scalers," but not in the traditional definition of the one we use on VSBattles
Shonen is literally, fundamentally, all about strong people beating each other up with cool abilities and blowing places up. Ground-breaking statement, I know. Constant escalation of power is almost a must in the genre. Piccolo blows up the moon? It's only natural that Vegeta has the power to blow up the planet, and even more natural for Frieza to be able to blow up a planet in his 1st form. Sasuke learns the Chidori? It's only natural that he has to create an even stronger move called "Kirin" that blows up ** because being blown up is cool. That's why there's manga like Black Clover straight up saying "They even had to burn [and freeze away] concepts" because that's cool and awe-striking. It's also because Dragon Ball is literally the grandfather of all Anime, but I have the feeling even without Dragon Ball, Shonen having characters blowing up would still remain a constant. Authors made characters blow up stuff because it's cool. In their minds, they take inspiration from Dragon Ball (God I know how much mangaka have seen and been inspired by Dragon Ball) and other factors in their life and say to themselves "Let's have our characters blow ** up"
Personally, I call it power escalation. There's probably a formal term for it somewhere, or I literally just said it and I don't know. Authors are only "power-scalers" in the way of saying "Character A would be more powerful than Character B because X, Y, & Z"
Is this just all a roundabout way of saying the obvious? Yes. It probably is.
