Gas Mask, Longcoat

Go To

A subtrope of Coat, Hat, Mask.

Basically any character that wears a gas mask and, well, a longcoat. Occasionally, there will be a good reason for this, like the character deals with cold weather and/or toxic fumes on a regular basis, but mostly these characters exist because it looks really cool. Trench coats or dusters seem to be the preferred apparel, though other kinds of long coats are acceptable. To make it easier to breathe, some models allow you to hook up a motorized air pump to make sure you get enough air.

Often works as a particularly stylish variant of Hazmat Suit.

Can be one sign of a Post Apocalyptic setting with an unlivable environment (see Post Apocalyptic Gasmask for that). Also common attire for Doom Troops thanks to the dehumanizing and vaguely skeletal/insect-like look of gas masks as well as the implication that Weapons Of Mass Destruction are in use by one or more sides. Either way, you are almost certainly living in a Crapsack World if this look is practical or common. See also Putting on the Reich.


Can overlap with Gas Mask Mooks if said mooks also include trenchcoats in their uniforms. Not to be confused with Badass Longcoat, although it can overlap. For a more historical version see Plague Doctor.

    Anime and Manga 
  • Shingen Kishitani from Durarara!! wears a gas mask at all times while visiting his son to protect him from Tokyo's air quality, even wearing it while showering (it's all but stated he's a Cloud Cuckoo Lander). He wears a lab coat, much like his son, Shinra, because of his occupation as a medical doctor. His second wife and Shinra's step-mother, also a doctor, wears a lab coat and a gas mask when she visits, but in a form of Goggles Do Nothing, she mostly wears it like a hat rather than a breathing device.

    Comic Books 
  • The Sandman, Wesley Dodds, from Sandman Mystery Theatre. Notable in that he also has a hat. Probably the Ur-Example in fiction, since he's been sporting the look since 1939.
  • Partially invoked during the first few arcs of Y: The Last Man: Yorick disguises himself with a gas mask and poncho, since his main aim is to disguise his male figure and features, rather than look intimidating or cool.
  • Dr. Kroenen from Hellboy. He is seen wearing a long coat as part of his Nazi uniform once or twice, but eventually trades it in for a significantly less awesome apron.
  • Major Maxim, hulking Nazi Super Soldier and main antagonist from the Danger Girl series, wears a similar getup to Kroenen.
  • Knights of the Dinner Table: Newt wears this outfit when playing his character Corporal Punishment in Heroes of Hackleague.
  • Vlad from Hack / Slash. The gas mask helps his breathing. The coat is to hide he looks like humanoid lizard.

    Fan Works 
  • Yognapped main antagonist Sben dresses this way to intimidate people. And because he's horribly mangled to the point of being unidentifiable as human.

    Films — Animation 
  • The mooks from Atlantis: The Lost Empire wear greatcoats as part of their uniform and gas masks during the underground expedition, which is rather prudent since the risk of poison gas pockets would be very real and the climax takes place in an erupting volcano.

    Films — Live-Action 
  • The Tatooine-informant alien in Star Wars: A New Hope who ratted out Kenobi and Skywalker to the Stormtroopers in Mos Eisley; he was an alien who looked like he had a gas mask, but he definitely had a long coat.
    • For that matter, Darth Vader could serve as an especially stylized example.
  • Kroenen from the film version of Hellboy is dressed in a Nazi uniform, with a black coat and black cap, and a metallic gas mask.
  • Resident Evil: Retribution. Umbrella Corporation soldiers, so they can look cool while Fast-Roping out the back of a tiltrotor gunship.
  • Peter Quill of Guardians of the Galaxy is introduced in this outfit when exploring a toxic planet, and since the mask is a Collapsible Helmet, he's seen in it a few more times throughout the film.
  • Bane in The Dark Knight Rises wears a variant of this.
  • Restoration features the main character, a Restoration-era doctor, venturing out to tend to plague victims in a plague mask and long coat. The film won an Oscar for best costume design.

    Live Action TV 
  • Doctor Who: The Tenth Doctor in "The Poison Sky". He usually wears a Badass Longcoat and wore a gas mask because of the toxic gas being released from the cars.
  • An episode of Angel had vampires using these to attack a group of Vampire Hunters in daylight.
  • The Masked Singer has the Deer, which is basically this trope with antlers on. The fact that he sings like a country blues veteran doesn't quite diminish how nightmarish he really looks.

  • The music video for The Sword's Fire Lances of the Ancient Hyperzephyrians features a group of survivors sporting a variety of coats, coat-like rags, robes, and protective masks trekking across an atomic wasteland. Their leader gets bonus points for having a staff to go with his hooded robe, blurring the line between this and Robe and Wizard Hat.
  • In Phase 3 of the Gorillaz, the Boogieman had this appearance, complete with red eye holes for his mask.

    Tabletop Games 
  • Imperial trench infantry in Mutant Chronicles, complete with Brodie helmets.
  • The Death Korps of Krieg from Warhammer 40k are an entire army of this. The Armageddon Steel Legion use this trope as well.
    • It should be noted that both are based on real world militaries from the same nation but of different eras. The Death Korps is intended to resemble World War 1 German infantry, whereas the Steel Legion bears more of a resemblance to the later Wermacht uniforms. Interesting fact: the original Death Korps models were just Steel Legionaires painted with skulls on their masks. Now only the Grenadiers and Quartermasters wear skulls.
  • Standard uniform of the Deathwatch in Unhallowed Metropolis

    Video Games 

    Visual Novels 
  • Clear from DRAMAtical Murder sports a gas mask and a long white coat for no apparent reason. He never removes his gas mask, even while eating. It's revealed later in the game that he wears the gas mask because his grandfather told him he must never show his face to anyone, probably because he is actually a robot whose face is identical to that of other robots. When he finally takes it off, it's a significant moment and goes towards establishing his humanity. He wears the long coat because it was his grandfather's.
  • Zero from Nine Hours, Nine Persons, Nine Doors uses the look. It serves to hide their identity by hiding their voice and concealing their face, and protecting them from the knockout gas he uses to kidnap the main characters.

    Web Comics 

    Web Original 
  • Death's Head, a supervillain with the power to cause spontaneous illness and infection, from the Global Guardians PBEM Universe, wears a World War II-era gas mask, a fedora, and a trenchcoat for his costume.
  • A-GENT 88 wears this, mostly to help protect people from his ability.
  • In Fallout: Nuka Break, we meet an NCR Ranger at the end of Episode 6 wearing the armor seen at the top of this page. Turns out he isn't even a Ranger at all. He just beat up a Ranger and stole his armor, which makes him even more badass.

    Real Life 
  • Many soldiers, particularly German ones, in World War I. Most likely the Trope Maker.note 
  • More primitive versions can be found in the Plague Doctor (Wikipedia articles on the profession and the costume), who were employed during the Black Plague. The plague doctor's mask possessed glass eyepieces, and the nose was filled with herbs to ward away 'bad air', which was one of the believed causes of the plague at the time. The doctor then wore long thick outer garments to protect them from their surroundings, and carried a cane to interact with things without directly touching them (think that claw thingy the trashman carries). Although there was very little the doctors could actually do for their patients besides taking note of the infected and instigating quarantines, they were paid relatively handsomely for the risk involved in their jobs. note 
  • The Loyon, an unidentified person spotted wandering in a Swiss forest, regularly seen for a decade. He wears a gasmask and sometimes a long camoufled coat. Although the previous link can look like a hoax (it is actually quite exaggerated), the Loyon (gender unknown) really exists (look here for an article - in French - from an actual Swiss newspaper).
  • OZK, Russian issue military hazmat kit, can actually be worn as a kind of oilcloth longcoat, if the circumstances don't require the full-body protection.
