6x20 Villains

Superpowered Willow is the best Willow.

Willow at her darkest. This and the next 2 episodes are some of my favorites in Buffyverse. Just delicious visually.

Also, a cute nod to vampire Willow: dark Willow goes "bored now" before flaying Warren alive. That was Bizarro world vampire Willow's catchphrase.
