Quiet Abilities

Quiet, known to the Soviet forces as Tixij (Russian: Тихий, "Quiet"), 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 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.

Also, submerging her in water could suffocate her like normal humans, even in black markings. but If she died by suffocate or any damage, exposure to direct sunlight would immediately resuscitate her.

Intangibility, allowing her to escape from restraints while her powers were active. This appeared to be the parasites manipulating her density, mass or state of matter, allowing her to become partly gaseous.
