Hey there!
Here's a super helpful guide on starting to create your character:
How to create a Roleplay CharacterI find it's useful to start with a description or image of what you want your character to look like, then start to add things like their strengths/weaknesses, powers, etc.
To choose a name, you can always go to adopt pets on here and use the name randomizer, or scroll through some people's pets for interesting names. You can also look at lists of names commonly found on baby-naming websites. My personal favourite way to find names is to use google translator and type in a world in english of a trait I want my character to have (ex. hope, leadership, etc.) and look at what they are in other languages, then base my character's names off those.
I'm sure if you google a list of super powers, you'll find a lot of unique ones. And of course you can always make your own!
This character is your own, so make her in whatever way you want! ^^
Best of luck! :)
