Morticia shouldn't be in the top 20.

Arya is way too high. I like her but she was just a child who revenge killed some people then joined the thousands of others who were fighting wights for a night. She was getting beat by the Waif as late as s6 then when she returned to Westeros we were supposed to think of her as this Xena level badass when she didn't do anything to earn it.

I don't know why Buffy had so many downvotes. She had such a great hero's journey, was the leader of her group, fought everything (vampires, ghosts, robots, aliens, gods, zombies, demons). She has a lot in common with Gabrielle, her optimism, forgiveness, curiosity, adaptability, can inspire others to improve themselves.
