Buffy the Vampire Slayer featured several compelling female characters throughout its run. These are some of the best.

When Buffy the Vampire Slayer was at its best, it provided some of the best television ever, as episodes like "The Body" and "Hush" show.

Perhaps no one needs to have a guest appearance in the new series than Alyson Hannigan as Buffy's best friend Willow. Their friendship was the glue that kept the Scoobs together, and we know if Willow could help Buffy with anything to do with the new challenges she's facing, the powerful witch would be there in a second.
