The Female Lead Without the Need for Help?
There are movies that show how beastly and overpowered their characters are, and some of those movies don’t need overpowered lead characters to show how useful and powerful they need to be. Eowyn, from the Lord of the Rings series, went out on an all-out campaign with her brethren to prove she isn’t someone you want to mess with.
Even Hermione, from the Harry Potter series, showed how knowledge and wits can create an iconic wizard. Then we have Bella, she showed her true colors from the very beginning of the franchise, going through all the trouble without her doing anything at all.
