Buffy Summers is the titular character from Buffy the Vampire Slayer. She's badass, amazing, and kicks the shit out of vampire's asses. What's not to love?
As we watch the series, we see Buffy grow from 'ditzy' high schooler to powerful leader, teaching Potential Slayers how to save the world from impending doom. She also falls in love with many, many undead men... it's a bit of a problem for her.
