COSTUME GALLERY
1) As Viper or Madame Hydra, she traditionally wears a “cat suit,” a sleeveless dark green material with heeled boots and long opera style gloves. Often times, Viper has bandoliers or belts of pouches draped in crossing fashion over her hips, and a holster at her side. Her long hair, naturally black and often dyed green, hangs over her scarred right eye. (Except when it's not scarred. Whatever.) [Captain America (1st series) #110]
2) At a point when she sought revenge on the X-Men, Viper adopted a new look. This black leather outfit was open and exposed at the chest and stomach. It had red lining, and coiling strips of green snake-like scales as a reoccurring pattern. Curiously, Viper had no noticeable scar as she wore her hair pulled back into a long, tight braid. As the Warrior White Princess of the Hellfire Club, Viper wore essentially the same outfit, but cast entirely in white. [Uncanny X-Men (1st series) #448]
3) After being killed by Valentina de Fontaine, Viper was resurrected by the HYDRA entity called the Hive through one of his cephalopods. This symbiosis brought her back to life, but with a massive octopus-like entity bonded to her skull, with elongated tentacles draping past her shoulders. [Secret Warriors (1st series) #15]
4) Sometimes she wears armor. [All-New X-Men (1st series) #8]
