Quiet (Japanese: クワイエット, Hepburn: Kuwaietto) is a fictional character from Konami's Metal Gear series.

Created by Hideo Kojima, designed by Yoji Shinkawa, and based on and voiced by Stefanie Joosten, Quiet appears in the 2015 action-adventure stealth game, Metal Gear Solid V: The Phantom Pain.

The character is a skilled assassin and sniper with superhuman abilities belonging to the covert strike force XOF, a rogue division of the American intelligence agency Cipher.

Depending on the player's actions, she can be captured by Venom Snake and eventually used as a member of his Diamond Dogs mercenary group to participate in missions.

"[15] As noted by Kojima himself, Quiet is the only heroic female character of Metal Gear Solid V, contrasting with the usual three of four in most of his earlier works; he described her as powerful yet vulnerable.

[17] Joosten talked of pre-release fan theories such as these of Quiet being a sex-changed Chico from the previous prequel games or a young Sniper Wolf, both of which she denied.

[19] Quiet is then seen deployed to Afghanistan by Skull Face and tasked with eliminating Soviet officers who are against his development of Metal Gear Sahelanthropus.

Speaking to Code Talker in Navajo, Quiet reveals that Skull Face intended to use her against Venom Snake and his army; she would allow herself to be captured and taken to Mother Base, then infect everyone there with the English-language strain of vocal chord parasites implanted in her.

These parasites would spread to and ultimately kill anyone on the base that spoke English (essentially all members of Diamond Dogs), including herself.

Unlike the Skulls unit of parasite-enhanced soldiers encountered through the game, Quiet retains an outwardly human appearance.

[29] The figure's soft, pliable breasts demonstrated on Twitter by Kojima and Shinkawa, the latter of whom did serve as its production supervisor,[30] were criticized in social media and in the press in the West.

[34] Famitsu positively commented on the "realistic fleshiness" of the figure,[35] in addition to focusing on the beauty of the "real Quiet" Stefanie Joosten and how well the "super sexy" game character was made to resemble her.

[36][37][38] A more conventional, 1/6 scale statue of Quiet was released by Gecco Corp in 2016;[39] its review by Dengeki Hobby praised this figure for its high quality and for showing the various aspects of the character's attractiveness and an attention to detail.

[41] The finished game drew more Western criticism of Quiet in both reviews and opinion pieces,[43][44] who felt the story did not sufficiently justify her lack of clothing.

[46][47] GamesRadar's David Roberts described Quiet as "one of the most complex and conflicted characters in MGS5", but that her depiction was an example of a "juvenile approach to sexuality" that typifies Kojima's work and the Metal Gear series as a whole.

"[49] On the other hand, GameZone's James Wynne felt that the game's story explanation was a valid enough reason for her scantily-clad appearance and succeeded in Kojima's aim to make Quiet "a true antithesis to sexy-just-because female characters."

"[50] Vince Ingenito of IGN called Quiet the most interesting character in the game, writing that her "warm, childlike sincerity and battlefield ferocity cause her to steal every scene she's in."

"[51] In an interview with IGN in 2023, Joosten said that the discussion around Quiet had been interesting, and that she respected the choices made for the character from a "fantasy" perspective.

[53] Roberts wrote that few developers would be willing to incur the wrath of players by creating one of the most powerful characters in the game by "integrating her completely so as to make her absolutely vital during some particularly difficult missions, then taking her away forever.

[61] Quiet was also portrayed by Alex Zedra, a character model who had starred in marketing campaigns for the Call of Duty series.
