Crying Wolf was the scout and sniper of the The Beauty and the Beast Unit. She was also the most powerful member of the unit, making up for the team's brute force. She, along with the other members suffered from Post Traumatic Stress Disorder.
She was recruited by Liquid Ocelot into The Beauty and The Beast Unit, where she was given a massive power suit in the form of a wolf, as well as an enormous railgun, which may or may not have been the very same railgun that Fortune had used during The Manhattan Incident years prior, that she could use to destroy anything in her path. While inside of her suit, Wolf was nearly invincible, only revealing herself to snipe using her railgun. Liquid told her that destroying Solid Snake would finally silence her inner demons, and placed her in charge of the Werewolf PMC.
During the events of Liquid Sun, Snake encountered Crying Wolf and the other members of The Beauty and The Beast Unit while attempting to sneak past a group of warring PMCs and rebels. The rebels had acquired an armored bulldozer and were attempting to crush the fleeing PMCs, when suddenly the bulldozer halted in its path. Confused, the rebels searched the front of the vehicle, only to find Crying Wolf holding the enormous weight back entirely by herself. Wolf and the rest of the unit then went on to murder all of the surrounding rebels, before leaving at Screaming Mantis' request.
Later, upon his return to Shadow Moses Island, Snake encountered Crying Wolf stationed between the two communication towers, guarding the entrance to the blast furnace - the same snowfield which Snake battled Sniper Wolf nine years earlier. Liquid, who had already arrived on Shadow Moses unbeknownst to Snake, sent a group of FROGS to assist Wolf in her elimination of Snake. Entering the snowfield, Snake heard the blood-chilling howl of Crying Wolf beginning her pursuit.
Working against a massive blizzard and using various trucks and trees as cover, Snake was able to eliminate Liquid's FROGS and eventually Crying Wolf herself.
