C. Viper

How C. Viper joined the Tourney
Crimson Viper, also known as Maya, is an American fighter employed by S.I.N., and presumed head of the "Battle Suit" Project. In reality, Crimson Viper is a secret agent under the employ of a U.S. government agency, presumably the CIA. She enters and participates in the latest world tournament under the guise of acquiring data for the Battle Suit for S.I.N., though her true motives are to acquire data from the BLECE Project (Pronounced Blees), in addition to eliminating "Number 15." ([[Seth]).

Burst Time (Hyper Smash)
Based on her Street Fighter IV Ultra Combo, Viper charges her glove before pounding the ground, causing an electric explosion that knocks her opponent into the air. As they begin to fall to the ground, she uses her boots to spin in the air, delivering a series of four high-damage flaming somersaults to the opponent.

Burning Dance (Final Smash)
Based on her second Super Street Fighter IV Ultra Combo, Viper jumps into the air then comes down flame-kicking her opponent in the neck, driving them into the ground and grinding the now-burning opponent's face along the ground while saying "Full Throttle!". She then performs a flaming backflip which knocks her opponent into the air and catches them with her forearms as they land. She then jumps into the air with her opponent's face in between her arms, and as she reaches the apex of the jump her gloves electrify the opponent. As she lands on her feet and her charred opponent falls to earth, she asks "Are you some kind of masochist?"
