Kara, Andrea Clark, then Buffy vs. Glory
Face growing hard, a tiny smirk came over her face. "Well, I gave you the chance." the really sad part? Glory ranted and was more speachy than she was most of the time. She'd point out that she had Jacen Solo and Superman on her side, but Buffy was fairly sure the reference would be lost on Glory.
When she lunged, Lucifer's sword came out from behind her back. Buffy could swear it was almost glowing with power. But that was probably all just in her head. Humming with power, yes, sending the vibrations down to her core. She'd win with this, Glory would go down. With Vi, Tim, and Dawn, not to mention the support team at their back. Things were different this time. Her demons really didn't stand a chance. The only real fight? Was between them, and Buffy already knew she could beat Glory with the right weapon, and that was all she needed to know. Because this was the right weapon.
Squaring off against Glory, Buffy cut the sword up toward the gods middle. Even if it didn't but her, she could still probably use it like an awkward bat and just beat the hell out of her.
