Roxy Richter
Roxy Richter, Ramona Flowers' fourth and only ex-girlfriend, is a complex, fiercely loyal, and highly skilled "half-ninja" who serves as a major antagonist in Scott Pilgrim vs. the World. Portrayed by Mae Whitman, she is a short, blonde-haired woman with a sharp tongue, a powerful whip-sword, and a deep-seated inferiority complex stemming from her relationship with Ramona, whom she views as having dismissed their romance as a mere "phase." Known for her near-instantaneous speed, ability to vanish in clouds of smoke, and her iconic first attack—where Scott accidentally punches her in the breast—Roxy is both a formidable fighter and a deeply emotional character whose vendetta against Scott is rooted in protecting Ramona's well-being.
