Sunset Bain

Sunset Bain is a character appearing in American comic books published by Marvel Comics. Created by writer Tom DeFalco and artist Steve Ditko, the character first appeared in Machine Man #17 (October 1980). Sunset Bain is known under the codename Madame Menace. She is both a rival and occasional love interest of the superhero Tony Stark / Iron Man. She is portrayed as a cunning and ruthless business magnate, serving as the founder and CEO of Baintronics, a powerful technology conglomerate specializing in artificial intelligence and robotics.

Bain attended the Massachusetts Institute of Technology concurrently with Stark, during which she seduced him into revealing the security codes for Stark Industries. Shortly thereafter, she infiltrated the company, stealing blueprints and prototypes that she later used to establish her own corporation. Bain and Stark clashed when he suspected she had used his stolen technology to construct a military vehicle, and their rivalry continued over time. Her primary objective is to dominate the technology market, both legally and illicitly.
