"You saved my life."
"I do not like being on my enemy’s debt. Understand this. Once the Skrull threat is over, we will be enemies again."
Captain America and Viper[src]
Madame Viper, or simply Viper, was one of Baron Strucker's lieutenants in HYDRA. She later joined the Serpent Society.


Early Life

"What happened to you?"
"What happened, is that I was given a reason to hate people like you."
Captain America and Viper[src]

Viper's early life is shrouded in mystery, but it is implied that something happened to her, which gave her scars on the right side of her face and made her hate people like Captain America. She eventually joined HYDRA and acted as one of Baron Strucker's trusted right hand lieutenants. During his time, Viper heard rumors of the Serpent Crown, which would give her the power to conquer the world in order to impose their new world order, using HYDRA to seek the crown, but without any success.

Skrull Invasion

At some point in time, she was replaced by a female Skrull who posed as her. The Skrull was captured and discovered by Nick Fury after some time.

After several months in a prison cell on a Skrull spaceship, Viper was freed by Captain America. Together, they freed other prisoners, both villains and heroes, after facing the Super-Skrull, they stole a shuttle and managed to escape. When Viper and the rest of the prisoners came to the Earth, they fought along the Avengers against the Super Skrulls, later she and King Cobra were captured by S.H.I.E.L.D.

Serpent Society

The Society tried to break her out, and wound up being trapped underground with Quartermain, Cap and Spider-Man. As the heroes tried to escort the civilians to safety the Society retrieved their members one by one. Due to Captain America having a weak shield and Spider-Man having run out of web fluid and having to lift up the collapsing street that was above them, Viper and the Serpent Society had managed to escape from the collapsing street.

Viper's fate remains unknown as she never appears again.

Physical appearance

Madame Viper is a tall woman with a voluptuous yet muscular built, toned broad shoulders, and long dark green hair, which covers the right side of her face. She has dark green eyes, wears green lipstick and maintains a very form-fitting green wardrobe as well that accentuates her body. She also has mysterious scars on the right side of her face, which she hides with her hair. She is also shown to be very buxom.


Madame Viper shows to be very hateful to anyone who are against HYDRA. Her scars caused her to have such personality. In desperate times, she was willing to work with her enemies to get things done and remind them that after it's over, she'll resume her hatred again. She is also impatient, when Captain America tries to save the human prisoners who were replaced.
