Doom and Doom II The box art for the original
Doom (1993), which was done by
Don Ivan Punchatz, shows 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, in which 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", and again in the cover art of
Doom II (1994) where he is fighting a
Cyberdemon with a shotgun. For the character's in-game sprite (seen at the ending of
Doom II), Doomguy wears green armor and a light grey helmet that conceals his facial features. Several corpses of other marines are occasionally encountered, and they feature the same uniform. 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, Doom II, and
Final Doom (1996), Doomguy's face is seen in the game's
HUD, where he is shown as a white male with blue eyes and light brown hair in a
buzz cut. Doomguy’s face displays a stern glare, and his eyes constantly dart left and right. Upon the player taking damage, the face provides feedback with an angered reaction, and the tilt of his face indicates the direction he has been attacked from. As the player’s health drops, Doomguy’s face also becomes increasingly bloodied and disheveled. Doomguy grins upon picking up a new weapon, and the most emotional face is seen when the player suffers 20
hit points or more taken away during a single attack, whereupon the HUD 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 the player heals 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 "ouch face" would later be reused in
Doom RPG, appearing whenever the Marine is attacked from behind. In
Doom 64 (1997), Doomguy has a slightly modified green armor with black highlights, a black helmet with an antenna, and a blue visor. In
Wolfenstein RPG (2008), 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 and Resurrection of Evil In
Doom 3 (2004), 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 and mouths a curse word. The Marine in the expansion
Doom 3: Resurrection of Evil (2005) is a different character than the Doomguy in
Doom 3, being an older-looking and somewhat more heavyset and weather-beaten
combat engineer with a dark
brush 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. It has been also noted for its visibly irreverent tone conveyed by its hand gestures,
fist bumping a small Doomguy
figurine, shaking his fist in rage before punching a monitor whilst looking at the corpse of a UAC worker, and
guitars. Some people consider that, "according to his computer log-in screen", his name is revealed to be Flynn Taggart, confirming the name the 1995
Doom novels assigned him. However, that is not a login screen but a password to open the original
Doom II .wad from within
Doom Eternal. Some question this logic, as of why would he put his own name as a password, while others consider this to be nothing more but a
Easter egg. Among those, there are "Taggart" comic books spread about, as well as the book on the shelf, titled "RET-CONNED: The Life and Times of Flynn Taggart", which could, also, suggest that the developers retconned that name. Doomguy also has access to alternate costumes, including a winged
unicorn skin. Some speculate that he stands about tall and weighs in armor; without it, with a weight of , though it is uncertain where exactly these claims have originated from. A life-sized figure of the Slayer made by Studio Oxmox for
Doom (2016) stands tall. However, a substantial portion of this height is provided by the figure's base, making it unclear how tall the figure portrays the Doom Slayer himself as. Other figures suggest a more modest height of 6 feet in armor.{{Cite web|url=https://www.darkhorsedirect.com/products/doom-eternal-doom-slayer-scale-action-figure-dark-horse-direct-exclusive ==Appearances==
