# Doomguy

Doomguy or Doom Slayer is the protagonist of the Doom franchise by id Software. He was created by American video game designer John Romero and was introduced as the player character in the original 1993 video game Doom. Within the Doom series, Doomguy is a demon hunting space marine dressed in green combat armor who rarely speaks on-screen. In Doom Eternal, he is voiced by American voice actor Matthew Waterson, while Jason Kelley voices the character in that game's downloadable content The Ancient Gods: Part Two. A different character with a role similar to that of Doomguy was portrayed by Karl Urban in the 2005 film adaptation.
Doomguy has appeared as a guest character in several other games, including Quake and Tony Hawk's Pro Skater as well as including his likeness as a customizable skin for the Mii Gunner character in Super Smash Bros. Ultimate, and being added as an outfit in Fall Guys and Fortnite. He has received mainly positive reviews.

## Concept and creation

Initially, the Marine is not referred to by name in the original game. Designer and programmer John Romero described this choice as increasing player immersion: "There was never a name for the [Doom] marine because it's supposed to be YOU [the player]". The character sprites were created by Adrian Carmack, based on an initial sketch and clay model he made. In 2017, Romero stated that he was the original model of the character for the cover box art. In 2020, Romero humorously stated that the name of the character was "Doom Guy". In 2021, Doom Eternal's director Hugo Martin revealed that a female Doomguy was nearly added to the game, but was scrapped due to how much of an endeavor it would have been.
Tom Hall's original design draft, "The Doom Bible", described several planned characters, all of whom went unused in the final version. The sole non-playable character, Buddy Dacote, bore the most similarities to the original game's eventual protagonist. "Dacote" is an acronym for "dies at conclusion of this episode", and Buddy was supposed to be killed by a boss at the end of the planned third episode. In the finished product, this nearly happens to the Marine in the final level of the first episode, but the character survives. Later, when asked, Tom Hall and John Romero confirmed that the marine is a descendant of Wolfenstein protagonist B.J. Blazkowicz.

## Characterization
### Doom and Doom II

The unnamed protagonist of the series is a Marine who is often referred to in the fan community as the "Doomguy". id Software chose a somewhat generic pictorial representation of the Marine for the box art, as well as for gameplay purposes (damage feedback and story transitions).
The box art for the original Doom, which was done by Don Ivan Punchatz, shows the Doomguy firing a weapon (which does not make an appearance in the final game) at a horde of Demons below him as one of them grabs his left wrist, while a fellow Marine (similar battle dress uniform, except in grey) in the background is rushing to catch up. This image is also used in the introduction screen of Doom, where the Doomguy has a shotgun clutched in his left hand, while a Baron of Hell kills the grey-uniformed Marine in the background. The Doomguy appears without a helmet, in the ending to The Ultimate Doom episode IV "Thy Flesh Consumed", then again in the cover art of Doom II where he is fighting a Cyberdemon with a shotgun.
For the player's in-game avatar in single-player mode (also seen at the ending of Doom II), the Doomguy wears green armor and a light grey space helmet that conceals his facial features. Several corpses of other Marines are occasionally encountered, and they feature the same uniform as the Doomguy. In multiplayer mode there is a palette swap applied; with players either green, indigo (gray), brown, and/or red, depending on player number.
For Doom and Doom II, the Doomguy's face is seen in the game's HUD, where it is shown as a white male with blue eyes and light brown hair in a buzz cut. In Doom, Doom II, and Final Doom, the Marine expresses little emotion at the horror unfolding around him, maintaining a stern and alert glare, eyes constantly darting left and right. When the Marine takes damage, his reaction is a mixture of pain and anger. The Marine grins upon picking up a new weapon, and the most emotional face is seen when the Marine suffers 20 hit points or more taken away during a single attack, where the player is supposed to show a shocked face. However, this behavior is actually broken in the original versions of Doom, Doom II and Final Doom, as said expression only shows if you heal 20 health during the period a large amount of damage was taken. It is fixed in most fan-made source ports made for the game, but most still allow the player to re-enable the broken "ouch face" functionality.
The Marine in Doom 64 has a slightly modified green armor with black highlights, a black helmet with an antenna, and a blue visor. In Wolfenstein RPG, it is hinted that the Doom 64 Marine is a descendant of William "B.J." Blazkowicz, to whom the Marine's helmetless look in the original games bears a striking similarity. In a reference to the Marine's confrontation with the Cyberdemon, when Blazkowicz defeats the "Harbinger of Doom", the creature states that he will return in the future to confront his descendants.

### Doom 3

In Doom 3, an alternate version of the Doomguy appears as the protagonist. He wears green armor with exposed arms, his facial features are not concealed, his muscular build is less exaggerated, and he has thick black hair. During the game, the character can interact with several characters, most of whom, like Sergeant Kelly, give the player some briefing regarding his mission. The character remains silent throughout and is portrayed as tough and fearless in the game's cut scenes; generally only glaring at the demons he sees. When he discovers the towering Cyberdemon for the game's final battle, however, he steps back in fear.
The Marine in the expansion Doom 3: Resurrection of Evil is a different character than the Doomguy in Doom 3, being an older and more heavyset combat engineer with a black buzz cut who wears pale blue armor. This character is also shown to take enjoyment out of using the demonic powers available in the game, as cutscenes show him grinning with glee upon discovering the Artifact.

### Doom (2016) and Doom Eternal

In Doom (2016), Doomguy is more vaguely characterized: Doomguy's title is now "The DOOM Slayer", is never seen nor heard other than from the first person, and other than gameplay at the beginning of the game that shows him having a white skin color and the muscular masculine suit seen in the introduction, practically no details are revealed. The DOOM Slayer's eyes and nose can be made out through the visor of his helmet on the game's box art, the 3D model viewer, and his Quake Champions appearance. It has been also noted for its visibly irreverent tone conveyed by its hand gestures, fist bumping a small Doomguy figurine, and a late-game moment where the DOOM Slayer decides to make a backup of a friendly AI rather than erasing it.
Doom Eternal is more detailed about the Slayer's characterization relative to the previous episode: Doomguy is seen without a helmet in first-person, and for the first time in the series' history, he also speaks, voiced in a flashback cutscene by Matthew Waterson. He is stated to be immortal, as he does not need to sleep, eat, drink or excrete. A room in his Fortress of Doom is filled with comic books, collectible figurines, and guitars. According to his computer log-in screen, his name is revealed to be "Flynn Taggart", confirming the name the 1995 Doom novels assigned him. Doomguy also has access to alternate costumes, including a winged unicorn skin. According to the character description, He stands about 7 feet 0 inches (2.13 m) tall and weighs 500 pounds (227 kg) in armor; without it, he stands 6 feet 8 inches (2.03 m) tall and weighs 360 pounds (163 kg). A life-sized figure of the Slayer made by Studio Oxmox for DOOM (2016) stands 205 centimeters tall, suggesting the Slayer was also the same height as in the previous installment.

### Novels

In the 1990s Doom novels, Doomguy is referred to as Flynn "Fly" Taggart. For the Doom 3 novels, a Marine with a similar role is named John Kane. His past is somewhat similar to that of Doomguy in the original Doom, having been demoted after disobeying the command to save some of his fellow Marines. During the Hell invasion, Kane is forced to take command of several of the surviving marines despite his stripped ranking. He battles the demons single-handedly, or with a few other marines. He is depicted as compassionate to his fellow survivors, working to save a child named Theo and to save the damned in Hell. After volunteering to enter Hell to retrieve the soul cube, Campbell is shown as very impressed by him. He and Maria start to feel romantic ties to each other. At the end of Doom 3: Maelstrom, Kane's leg is blown off and he is admired as the "man who saved Mars City".

### Film

Arnold Schwarzenegger, Vin Diesel and Dwayne Johnson were mooted for the role of the Marine in the 2005 film Doom, with Karl Urban ultimately cast in the role of John "Reaper" Grimm in September 2004. Urban underwent military training for two weeks under military advisor Tom McAdams. The film's first person shooter sequence, told from Doomguy/Reaper's perspective, was completely directed by visual effects supervisor Jon Farhat and was filmed in 14 days after a planning period of three months. While the scene is one continuous shot, multiple cuts, that Farhat called "hook-ups", were made during filming, Farhat stated: "You can do it by moving a camera, and passing something, and cutting. And then rolling the camera again on a subsequent date." Other hook-up styles were used by using a green screen or blue screen when a door opens or jump-cutting by whipping an object. Doomguy/Reaper's gun was only used on-screen when it was needed due to its size affecting the aspect ratio.
For the 2019 film Doom: Annihilation director Tony Giglio created the character of gender-swapped Marine Joan Dark after taking inspiration from The Terminator and Aliens, feeling that a female protagonist would be more effective in a sci-fi action film. Joan was named after Joan of Arc. Four suits were produced for the imps, with one designed for leaping. Inspiration was drawn from Doomguy's depiction in the first three Doom games, as Universal did not retain the rights to the Bethesda version. Amy Manson and Agleya Gumnerova were then confirmed to have been cast in the role. Dark's depiction as a Doom Protagonist received negative criticism from fans.

## Cultural impact
### Reception

In 2009, GameDaily included the Doom Marine on its list of "ten game heroes who fail at the simple stuff" for his inability to look up and down in the original series. UGO Networks ranked the Marine fourth on its 2012's list of best silent protagonists in video games, noting his courage to continue in silence even when faced with Hell's army. In 2013, Complex ranked the Doom Marine at number 16 on its list of the greatest soldiers in video games for being "the original video game space marine" and "one of the classic silent protagonists". Both CraveOnline and VGRC ranked the Marine the fifth most "badass" male character in the video game's history. Kirk McKeand of VG247 described Doomguy as "Jesus with a super shotgun". David Houghton of GamesRadar claimed that Doomguy is the smartest player character around, even with fist bumps, violence and zero dialogue. In 2021, Rachel Weber of GamesRadar ranked him as the 47th most iconic video game character.
The Doom Marine's incarnation from the 2016 game has received special acclaim for its characterization and how the game presents the player character as a representation of the player playing Doom: writing for GamesRadar, David Houghton called the presentation "incidental, not explicit", which allows the players to immerse themself completely in the character. Christian Donlan writing for Eurogamer theorized that "the guy in Doom is playing Doom", and explained that the main character's impatience with exposition is analogous to "the temporary frustration of being inside Doom while not being able to play Doom". In his column Extra Punctuation Ben Croshaw wrote that the game "establishes the player character as someone who doesn't give a flake of dried Marmite for the larger context, and only cares about ridding the planet of demons. Which is hopefully representative of the player's motivation." Additional praise was given for the subtlety of Doomguy's expressions: James Stephanie Sterling noted that both the "glory kill" moves and additional pieces of animation "reinforce his consistent sense of irreverence", Sterling, along with a number of other reviewers including Houghton, Donlan, and Croshaw from Zero Punctuation noted the initial moment of the game with Doomguy throwing away a communications monitor while a mission briefing plays as a minimalistic, but effective way to convey the entire character's motivations.
Doomguy was a popular choice for inclusion in the roster of Super Smash Bros. by fans, and also by multiple websites, including PC Gamer, GamingBolt, GameRevolution, and Shacknews staffs.

### In popular culture

The character has been the subject of extensive fan art. One popular variant involving them has fans creating and sharing images of his hypothetical visage using 3D graphics software program and AI enhancements on social media platforms. On May 4, 2021, Bethesda featured Doomguy as part of a Star Wars Day tribute on its official Twitter account.
When Doom Eternal was delayed and released the same day as Animal Crossing: New Horizons, fans of both games began creating and sharing artwork depicting Doom Slayer and Isabelle together as friends, which eventually trended on social media in 2020. Commentators responded positively towards the fan-made pairing, including acknowledgments from Aya Kyogoku, director of New Horizons, as well as Bethesda. Because of this pairing, when Doomguy was added as a Mii fighter costume in Super Smash Bros. Ultimate in October 2021, together with Isabelle on the roster, the final update of the game was dubbed "friendship" and "love story" by video game publications. The Doomguy and Isabelle friendship pairing has also been subject to other forms of fan labor, like a fan video and cosplay.
John Romero titled his autobiography Doom Guy: Life in First Person.
