Why Buffy is Buffy

She has supernatural powers to destroy demons and vampires. She is chosen. She has senses regular folk don't have, able to sense an evils motives and whereabouts. But that is not why she is strong. It is her heart and courage.

Season 7. Biggest evil ever approaching. Buffy starts to form an army ala Lord of the rings to take on the evil. She and they are losing. After she gets her ass kicked by an uber-vamp, her people aren't feeling so great and neither is she. These are her next words, as she can barely talk and stand:

(note - "the first" symbolized the original evil, before evil things were")

"I'm beyond tired. I'm beyond scared. We don't know how to fight it. We don't know when it'll come. We can't run, can't hide, can't pretend it's not the end, 'cause it is. Something's always been there to try and destroy the world. We've beaten them back, but we're not dealing with them anymore. We're dealing with the reason they exist. Evil. The strongest. The First. . . . I'm standing on the mouth of hell, and it is gonna swallow me whole. And it'll choke on me. We're not ready? They're not ready. They think we're gonna wait for the end to come, like we always do. I'm done waiting. They want an apocalypse? We'll give 'em one. Anyone else who wants to run, do it now. 'Cause we just became an army. We just declared war. From now on, we won't just face our worst fears, we will seek them out We will find them, and cut out their hearts one by one, until The First shows itself for what it really is And I'll kill it myself. There is only one thing on this earth more powerful than evil, and that's us. Any questions?
