Emotions in mha and it's affects on quirks.
I wanted to talk about something in mha powerscaling not related to any specific character like usual. I think this applies to all characters. Most shonen use emotions to make people stronger so it makes sense
A common occurrence in mha is characters emotions having a factor on the power of their quirk,
In chapter 212 when izuku is losing control of blackwhip the first thing ochako does is tells him to calm down. Implying emotions are factors to power. His emotions his making him lose control of his power. In 213 banjo tells izuku using power in anger will work out for him and to control his emotions. In chapter 287 when bakugo gets stabbed and 367 (funny number) when izuku sees bakugos body. izuku remembers banjo telling him this. Implying significance.
In 357 endeavor uses his rage against afo.
All might is able to go beyond his 100% at the usj because a real hero will always find a way to win. He's emotions pushing him above 100%
And finally the thing that supports this the most. All for one. Afo becomes more vulnerable to shigarakis emotions the younger he gets which makes him stronger. Meaning once again emotions are amping quirk output
