Quiet

Quiet, known to the Soviet forces as Tixij, was a female assassin during the 1980s. Originally an assassin for XOF, Quiet later defected to Diamond Dogs after being defeated by Venom Snake. Quiet wore a minimal amount of clothing at all times because she could only drink or breathe through her skin following parasite-treatment due to the serious injuries she had sustained while trying to kill Big Boss during the hospital raid; wearing too much clothing would lead to suffocation. After being defeated by Venom Snake in Afghanistan following a tense sniper duel, Quiet became a prisoner at Mother Base until she was allowed to accompany Venom Snake on missions as a buddy. Her weapons included two lethal sniper rifles nicknamed Wicked Butterfly and Sinful Butterfly as well as the non-lethal Guilty Butterfly. Quiet, as an XOF operative, was an extremely efficient and ruthless individual, viciously murdering two innocent hospital personnel without hesitation or remorse. She was also very dedicated to her job and was willing to do anything to get her mission done, taking the horrific pain of being lit completely aflame for several seconds before finally succumbing to the agony. She also fought as relentless as she could, even attempting suicide, when Venom Snake attempted to capture her. She was also able to withstand continued torture while barely making a sound. However, the more time she spent at Mother Base, the more she began to change into a more caring and moral individual. After her capture, she was mostly indifferent and apathetic towards her situation but took an interest in Snake. Upon reaching maximum bond level, it's implied that Quiet developed romantic feelings for Snake, and in turn became a more benevolent person. Her examples of humanity/benevolence, and compassion, included playing with Snake in the rain, lighting Snake's cigar for him for his birthday, staring at him affectionately in the ACC, and even risking her life to save a child's memento. Regardless, Quiet still had the capability of being a cruel person if she believed it appropriate, attacking two Diamond Dog soldiers, the first for trying to clothe her, the second for being infected with a vocal cord parasite. She was also perfectly willing to kill anyone on Snake's command, and savagely massacred an entire squad of enemies after one of them attempted to rape her after nearly drowning her.
