Viper

Sabine Callas, or better known as "Viper" in the VALORANT project, is a woman of 30 year's old coming from the United States, and having a master's degree in science.

Attracting attention with her jet black hair and venom green eyes, Viper also has a black mask. When Viper uses her ultimate ability, this mask turns into a gas mask which covers her whole head. She dons a green skin-tight body suit accompanied by sharp black shoulder plates, and wears customized gloves wherein she can release her toxic gasses. She wears black boots that reach her thighs, and she carries a container on her back which carries her toxins.

Sabine Callas, an American chemist working for Kingdom Corporation, played a critical role in the rediscovery of radianite. Her research drew the attention of the Scions of Hourglass (SoH), a secretive organization determined to keep radianite hidden. They sent their assassin, "Ghost," to kill her. However, during the assassination attempt, Callas fought back, trapping Ghost in a chemical test chamber. This transformed him into a memory-wiped phantom, later known as "Omen."

Viper, now isolated and consumed by vengeance, deceived Omen about his past and recruited him to work alongside her. Together with Kingdom colleague Liam Byrne "Brimstone", they founded the secretive VALORANT Protocol. Callas adopted the call sign "Viper" and became Brimstone’s second-in-command. Viper recruited agents and led missions to combat Omega Earth threats.

Viper is a savage and confident agent who doesn't fear enemies, and in fact desires the enemies' fear. She does not hesitate to call herself a villain and a monster, and will act like both if it means the success of her objective. Just like her abilities, she can be quite "toxic", however she is seen being more amiable and caring towards her teammates, but she will not hesitate to reprimand them harshly should they make major miscalculations in the battlefield.

Thanks to her customized gloves, she can launch toxins and various gadgets with them. Thanks to her mask, she can breathe her own venom without any problem. In addition, Viper is an excellent shooter with any type of weapon.
