"I'm Buffy, the vampire slayer. Why's my name Buffy? BECAUSE I'M BUFF, BITCH!"
―Buffy explaining her name.

Buffy Summers is a vampire slayer. She's super strong, super fast, and other stuff. That means she can kick, no, PWN, your ass. If you see Buffy, and she has an angry look on her face, you better RUN.
