Crimson Viper

"Yes, that's right... Understood"

- C.Viper

Crimson Viper is a character in the video game, Street Fighter IV. At first, it looks like she's working for Seth, the main villain of the game, but it turns out she isn't. She's working undercover by the CIA, under orders to retrieve data on the BLECE project and kill Seth. Nevertheless, due to occasionally standing against other heroes from the franchise she is considered by the other heroes from the series a villain

She uses her Battle Suit to fight her opponents, and it is equipped with electrical gauntlets that can make the ground shake as well as jet boosters in her boots that can be used as flame throwers.

C.Viper has a daughter named Lauren. This makes her one of the first mothers in the Street Fighter franchise.

She is voiced by Mie Sonozaki in Japanese and Michelle Ruff in English.

Personality
C. Viper's working personality is superior and condescending, as seen in her interactions with Chun-Li, Cammy, and Hakan. However, she is also genuinely interested in the inner workings and problems of the other fighters, as shown in her various win-quotes, but when it comes to her missions, C.Viper will not let anyone stop her from completing her goals.

As mentioned in her win quotes, her current personality is a far cry from her younger years. It is implied that she was something of a wildcat and a thrill seeking delinquent as a teenager, before the events that got her to be a responsible and focused adult.

When C. Viper is not doing missions, she is shown to be a loving mother for her daughter Lauren, as shown in her Super Street Fighter IV ending.
