C. Viper
C. Viper works in the S.I.N. organization, carrying out many missions for Seth as his personal lackey. However, unbeknownst to Seth, Viper is secretly working for the CIA and has managed to work her way into Seth's trust. She is actually investigating the BLECE project and aims to take down Seth, S.I.N., and the Living Incubator project being secretly funded by S.I.N. However, despite her rise in the ranks, Seth's trust of Viper has wavered of late as he has begun suspecting that Viper is not quite who he originally thought she was.
In a nutshell
Widely considered the most technical characters in the game, Viper requires 
levels of manual dexterity and mindgames to be effective. Diligent players, however, are rewarded for their efforts with some of the most potent offensive tools in the game. Her mix-up is absolutely devastating, being able to cross up with Aerial Burn Kicks mixed in with safe Overheads and super jump cancels, which she can use to combo into her Ultras for well over 50% of the opponent's health bar. However, as great as Viper is in mixing up opponents, her wake-up options are not strong so she can easily be mixed up herself. The key to winning with Viper: constant offense and never letting the opponent get a chance to think.
