Marine in the final level of the first episode, but the player survives. Later, when asked, Tom Hall and John Romero confirmed that the Marine was, at least originally, a descendant of Wolfenstein protagonist B.J. Blazkowicz. Characterization Doom and Doom II The unnamed protagonist of the series is a Marine who often referred to in the fan community as the "Doomguy". While id Software chose a somewhat generic, white male pictorial representation of the Marine for the box art, as well as gameplay purposes (damage feedback, story transitions), the true identity of the Doom Marine is meant to be the player themselves and so these depictions should only be considered illustrative. On the box art for the original Doom, which was done by Don Ivan Punchatz, this shows the Doomguy firing a weapon (which doesn't 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 in 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 green and grey for players one and two in co-op, while in deathmatch there is a choice of green, red, brown and indigo/blue. 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 light brown hair, a buzz cut, and blue eyes. 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
