I feel like this needs clarification.
The idea I’m vouching is similar to My Hero Academia in that, the characters never gain any new powers. They technically stay at the same strength. How they grow is in how they use their powers and their creativity with what they already have.
It completely spits in the face of ‘new powers as the plot demands’ because nothing ever comes completely out of nowhere, it’s always the same power. Just used in a way that hadn’t been used before.
For example, take X-Ray guy that we just met. What if, instead of using his power to look through inanimate objects, he turned that power to a person in order to see their internal structure, and find weakpoints that he could exploit. Gaining him the edge in a hand-to-hand fight. It’s the same power, but used in a new way.
In Avatar, when Katara first used Bloodbending, that was an example of this kind of growth. Controlling another person wasn’t a new power that came out of nowhere. It was applying real-world logic to the idea of Controlling Water to Control-The-Water-Inside-A-Person. It was a logical leap that led to a power-up.
It’s a form of character progression that requires the character themselves to actually progress, because they can’t rely on gaining a spontaneous power-up in the heat of the moment.
It’s the contest between ‘gain new powers v.s. learn how to better use your existing ones.’ The former is flashy, has spectacle, but is ultimately hollow because the progress doesn’t reflect the character.
Whereas being given a tool and being told to make it work for the situation they’re in takes more from the character. They have their tools from the beginning, and that’s what they’re goanna get, and they need to make it work. It requires resourcefulness, cleverness, and makes them progress in a way that actual people do.
I highly implore someone of the opposing view to make their counterargument, and for everyone to at the very least read both before you finalize a decision.
(And remember, if you voted too soon, you can change it).
