If I were to put a character in the character sheet would I put that in their list of powers?

No

but I want to put everything in one list so one list will have everything even a weakness so what do I call the list?

Just put it under weaknesses.

You can have one list of stuff but also have weaknesses in that list

But what do I call the list?

Is it for a role play of some sort

No, just a character I’m making for fun

Then you could just do “Superpowered Character/Form/Personality. You can call the list whatever you want. I’ve made almost different superpowered characters in my free time, changing, up/downgrading, and tweaking them so that I can have one for a different purpose. I have them listed under such things like Forms, Personalities, Superpowered Characters, and Fandom Characters

It’s your list. Have fun, make mistakes, revise those mistakes, until you have the perfect Superpowered character(s) that fulfill your needs or interests
