Doomguy in a cutscene from The Ultimate Doom's fourth chapter.
Series Doom
First game Doom

The Doomguy is the protagonist of the Doom series of video games created by id Software, and its sequels and spin-off media.

In all the games, he is a former marine, wearing green combat armor, working for the Union Aerospace Corporation. He never speaks (there is usually no one around to talk to). In the games, he is never referred to by name. The game's designer, John Romero, said this was to increase player immersion: "There was never a name for the DOOM marine because it's supposed to be YOU."[1]

In the Doom novels, the main character is referred to as Flynn "Fly" Taggart. However, Tom Hall's original design draft, also known as The Doom Bible, suggested his name was Buddy Dacote ("Dacote" standing for "Dies at conclusion of this episode", which is indeed the fate of the character, although he continues his adventure in the second episode).[2] In the Wolfenstein RPG, it is implied that Doomguy is the descendant of William "B.J." Blazkowicz. In the game Blazkowicz defeats the "Harbinger of Doom" (after taking off one arm and one leg), the creature states that he will return in the future to confront his descendants (this is a reference to the Doom guy's confrontation with the Cyber Demon).


Classic Doom Series

On the box art for the original Doom, the Doom Marine is portrayed as a muscular man wearing green armor as well as a light gray space helmet that conceals his facial features. He is firing a plasma rifle and fighting off a demon that is grabbing his left wrist. The introduction screen of Doom is slightly different, as he still has his plasma rifle but is also clutching a shotgun in his left. The player's in-game avatar, as seen in multiplayer and in the ending to Doom II, is based on this depiction. Colors in multiplayer include green, red, brown and indigo[3]. In Doom 64, the Marine is portrayed as appearing to have lost some weight, with slightly modified black armor and a black helmet with an antenna. His visor is blue rather than grey.


The Doom Marine's actual face is seen in the game's HUD, where he is shown as having light brown hair, a buzz cut, and brown eyes. The Doom Marine also appears without his helmet in the cover art of Doom II and also in the ending to The Ultimate Doom Episode IV Thy Flesh Consumed. In Thy Flesh Consumed, the marine's face is similar to what is depicted in the HUD, although for some reason his armor and pants are a darker shade of green. His face is never seen in Doom 64.

The Doomguy's personality is never examined in any of the games, although his past suggests that he has a strong sense of right and wrong. In the prologue of Doom, it is told that he assaulted a superior officer when ordered to fire upon civilians, and was therefore reassigned to the Martian outpost in which the game takes place. The back of the SNES port box cover describes him as 'one angry marine with a handgun and a bad attitude.' At the start of Doom II, shortly after having arrived on Earth and realizing that a zombie is attacking the people, he instantly blows away the monstrosity with his sidearm. Later, having fought his way to the spaceport and deactivated the force fields to allow Earth's population to escape, he nonetheless volunteers to stay behind and find the source of Hell's incursion. During the events of Final Doom, he promises to slay as many of the Demons as possible after they overran a moon base and slew the entire population (In the TNT: Evilution storyline) and in the Plutonia Experiment, he single-handedly enters the infested UAC complex that contained the Quantum Prototype Accelerators after he learned that an entire Marine platoon with heavy air/ground support are on their way to assault the complex, and because the Marines have never encountered the Minions of Hell, he knew they wouldn't stand a chance. In Doom 64, he is depicted as having nightmares due to his experiences, including the admittedly traumatizing descent into Hell itself. He fights his way through a long-sealed base and descends into Hell once more, alone, and when he defeats the Mother Demon, he decides to remain in Hell to make sure an invasion never happens again. His fate there is unknown.

In Doom, Doom II: Hell on Earth, and Final Doom, he appears to enjoy killing monsters: after he picks up a new weapon, he smiles devilishly; he grits his teeth after firing his weapon for a brief period of time; he clenches his teeth in anger whenever he takes damage and is heard to gasp or scream if killed; and his eyes are constantly and alertly darting left and right. The end game text for Thy Flesh Consumed also reveals that the rabbit killed in a previous cutscene was his pet rabbit Daisy — he is shown holding its severed head with a look of anger and vengeance on his face.

The Doom box picture of Doomguy fighting is the same as the inscriptions found on the Martian tablets in Doom 3, where the Hero is seen fighting the demon horde; however, on the Doom 3 tablet, the location of the demons is reversed and the Hero is portrayed as a muscular figure holding the Soul Cube rather than a rifle.

Doom 3


In Doom 3, Doomguy appears similar to his classic Doom incarnation, with the exception that his facial features are not concealed, since he does not wear a helmet (even though all other marines in the game wear the same helmet as the original Doomguy). He is more exaggerated, and muscular. He has black hair and appears to be in his mid-twenties or early thirties. The 'ab-spot' on the armor is also covered.

There is no background history on Doomguy in Doom 3; apart from the fact that he had just recently arrived on Mars, and is the newest member of the Marine detachment sent on the planet, his past remains a mystery. It is established he is a corporal and was sent to replace one of the marines that had mysteriously disappeared. When Dr. Betruger opens the gateway to Hell, he somehow manages to avoid being transformed into a zombie and ends up fighting through the UAC facility to survive.

This time, Doom's plot is similar to that of the original Half-Life (which itself shared similarities with the original Doom); before the unexpected accident, the player can talk to several people, but most of them do not say much other than the fact they are busy and the UAC base is a frightening place. However, there are several characters, such as Sergeant Kelly, who give the player some briefing regarding his mission, especially after the demons invade the UAC base. Even on these "chatting" occasions, the player character is addressed simply as "marine" and remains silent.

The Doom 3 Doomguy is portrayed as tough and fearless in the game's cut scenes; He generally just glares at the creatures he comes to witness, including several bizarre and disturbing psychic visions. He does however show fear when he sees the towering Cyberdemon, just before the final battle of the game.

In the Doom 3 novels his name is John Kane, interestingly the same last name as Quake 4 protagonist Matthew Kane. His past is elaborated as similar to the character in the original Doom, only having been demoted after disobeying command to save some of his fellow marines. He is a combat veteran among various of the wars raging on Earth for its remaining resources - including one between the United States and Russia. After arriving on Mars he finally resigns to his fate as a "glorified security guard." Whilst there he befriends fellow marines such as Maria Moraetes - a marine with a similar fate.

During the hellish invasion he is forced to take command of several of the surviving marines - stripped ranked aside. Afterwards he battles the demons singlehandedly or with a few other marines - such as Maria, Andy Kim, or Jack Campbell. He is shown to be very compassionate to his fellow survivors, working to save the child Theo, and even working to save the damned in hell. After volunteering to enter hell to retrieve the soul cube, Campbell is shown as very impressed by him. During all of this, he and Maria start to feel romantic ties to each other. During the end of Maelstrom his leg is blown off, and he is admired as the "man who saved Mars City."

Doom 3: Resurrection of Evil


In Doom 3: Resurrection of Evil, the main character is different from Doomguy of Doom 3 even though he resembles him. This Doomguy is a Combat Engineer, and thus is trained to operate a remote manipulation device known as the Grabber. Like Doomguy in Doom 3 he has black hair, but wears blue armor, and appears to be somewhat older than his Doom 3 counterpart, based on his heavily-weathered facial features.

The game presents very little information on his background, only that he is part of a detachment of Space Marines under the command of Dr. Elizabeth McNeil sent to investigate the Mars UAC facility in the aftermath of the demon invasion. While investigating the Martian ruins he finds and touches the Heart of Hell artifact (simply called The Artifact, also known as the Blood Stone), which releases a wave of energy that disintegrates the rest of his squad and opens another portal to Hell underneath the UAC base. In Resurrection of Evil, he appears to be more of an anti-hero in outlook, as he seems to enjoy using the Heart of Hell artifact, which ended up killing almost everyone at the base because of him.


In the film adaptation, John "Reaper" Grimm is the son of UAC scientists who were killed in an accident during the early excavation of a Martian dig site. Reaper abandoned his scientific heritage and joined the military to forget about this personal tragedy, eventually becoming a member of the elite Rapid Response Tactical Squad. Grimm, his commanding officer Sarge (The Rock), and the other members of the RRTS are dispatched to the UAC Mars Facility to investigate the disappearance of several scientists, which ultimately pits them in a confrontation against humans who have mutated into the classic Doom "demons" after being injected with an artificially created "24th chromosome".

Grimm's personality can be seen as rather angsty, as he is still dealing with his guilt over his parents' deaths and his concern for his sister, Dr. Samantha Grimm, a researcher at the UAC Mars Facility. However, like his computer-game counterparts, he has no problem killing multiple demons and even his own commanding officer, Sarge, after the latter begins to murder unmutated civilians in order to contain the outbreak and is infected himself in the process.

Near the end of the film, Grimm is fatally wounded and injected with the 24th chromosome by his sister in order to save his life. As she explains, not everyone is made into a monster by the chromosome, and Grimm is instead granted superhuman strength, reflexes, and regenerative abilities. These new abilities allow him to stride through the infested base with ease, single-handedly mowing down a small horde of demons; among those killed are many zombies, several imps, a Hell Knight, and a Pinky Demon (all seen by the audience in the game's classic first person perspective). After killing the now-mutating Sarge, Grimm leaves the base with his nearly-unconscious sister in his arms.

References to Doomguy

  • Doomguy's corpse makes an appearance in a secret area in Duke Nukem 3D: he is posed halfway through his Classic Doom death animation (clutching his throat and gurgling his own blood), surrounded by various Satanic iconography. Upon seeing him, Duke Nukem remarks, "That's one doomed space marine."
  • In the Windows version of Tony Hawk's Pro Skater 3, the Doomguy is a secret skater [1] [2], added by developer Gearbox Software, who ported the Windows version. This was included because Activision, publisher of the Tony Hawk series and Doom 3, wanted to promote the latter, still in development. Doomguy has decent to good ability ratings, except for "Air", "Hangtime", and "Ollie" (which are excessively low; a joking reference to the lack of jumping in Doom).
  • In the PlayStation 2 video game James Bond 007: Agent Under Fire, the mercenaries in the first level are based on Doomguy from the original game. They all wear short green shirts, are obviously well-built and some even wear a gray head-mask very similar to his.
  • A mod for Quake II allowed the player to access the original characters, weapons, and enemies from Wolfenstein 3D, Doom II, and Quake. Depending on the character used in normal gameplay (playing through the normal Quake II scenarios), the weapons they receive and the appearances of powerups and ammo change to fit that character's game. There is a story mode that also utilizes the appearances of the various enemies all together (the player must fight off zombies, demons, Strogg, and Nazis all at the same time). Notably, the mod used content taken directly from the games in question, and for this reason was contacted by id Software and ordered to cease production.[3].
  • Since Doom 64 referenced Freddy Krueger, in Wes Craven's New Nightmare when Heather Langenkamp is talking to her friend about Freddy, he replies "Yeah, we don't have a chance. I feel like Doomguy."
  • In Quake III Arena, the Doomguy appears in 3 later levels under the name "Doom." The character "Phobos" is also a Doom Marine, though his skin is darker and his armor is orange instead of green. The third Doom Marine in the game, "Crash", is mentioned as being Doom's female training instructor before arriving at the Arena.
