Willow Rosenberg — Buffy the Vampire Slayer

Alyson Hannigan

Alyson Hannigan’s Willow Rosenberg grew from Hellmouth nerd to magical powerhouse on Buffy the Vampire Slayer — found family, online fandom fuel, and a dark-arc that still sparks discourse. How I Met Your Mother later minted sitcom ubiquity. TV Flash keeps her at the intersection of genre literacy and laugh tracks.
