What are some strong and powerful girl names?

I’m writing a book and the main character is a young woman full of ruthless ambition. She is strong, confident, powerful, and has a bit of cruel streak. I’d like a name that represents all those traits, a meaning to match would be nice but not required.

I think [name_f]Liza[/name_f] or [name_f]Eliza[/name_f] are feminine but strong. Maybe also [name_f]Penelope[/name_f], [name_f]Sadie[/name_f], [name_f]Cleo[/name_f] or [name_f]Philomena[/name_f]

On the top of my head: [name_f]Athena[/name_f], [name_f]Freya[/name_f], [name_f]Matilda[/name_f], [name_f]Rowena[/name_f], [name_f]Tatiana[/name_f], [name_f]Demetria[/name_f], [name_f]Leonore[/name_f].

When reading this, I immediately thought of something mythical, like other comments have picked up on. Here are a few suggestions:
[name_f]Freya[/name_f]
[name_f]Io[/name_f]
[name_f]Leona[/name_f]
[name_f]Athena[/name_f]
[name_f]Violet[/name_f]
[name_f]Trixie[/name_f]
[name_f]Liberty[/name_f]

[name_f]Jocasta[/name_f] [name_u]Lawrence[/name_u]

I instantly thought of [name_u]Vivian[/name_u] and [name_f]Scarlett[/name_f]… probably because what you described reminds me of [name_f]Scarlett[/name_f] O’[name_f]Hara[/name_f].
