DRACULA?
"Hes toast. Now, if he were young and cute, that might put Buffy in in a bind."
CATWOMAN?
They would only fight for about five minutes, and then theyd find that they actually have a lot to talk about.
THE ALIENS FROM ALIENS?
OK, they would actually kill her.
MULDER AND SCULLY?
Mulder and Scully would solve a mystery before Buffy. But if hey were up against Giles (Buffys mentor) and Willow (Buffys best friend), then it would be a race.
XENA?
I love Xena very much, but Im not going to tell you she could beat up my Buffy. Couldnt happen.
