History WMG / Doom2016

Others have simply evolved biologically between the two games, notable ones being Cacodemons and Imps. With the twist of ''Eternal'''s demons being [[spoiler:human husks]], their demons are likely nu-demons that arose after the 'classic' breeds of the olden games went extinct.

* With his BadassBaritone, you’re basically describing a fleshy, evil Optimus Prime. Amazing.

There are problems, of course. The first is human nature- would humans really settle for a safer, sustainable power source if it means surrendering the comforts of Argent Energy? And would the UAC be willing to surrender their monopoly on energy to benefit the rest of mankind? Probably not. And the Doom Slayer ( [[https://tvtropes.org/pmwiki/pmwiki.php/ComicBook/Doom who we all know is very concerned about the environment]] ) realizes this and acts accordingly, out of grief and rage.

[[WMG: The Doom Slayer has [[UnderTale Determination.]]]]

[[WMG: the Doom Slayer is the result of a Merger of Souls of the DoomGuy and the Traitor]]
The would-be Doom Slayer is the traitor of the Night Sentinels, seeking atonement and consumed with rage at what happened to his son, During his subsequent rampage was then possessed by the spirit of Doomguy, this might have been a blessing from heaven, empowering him with there greatest warrior, or perhaps Doomguys soul was just so persistent he became a ghost/demon on his own(he would certainly make a good embodiment of wrath)forming the Doomslayer, the culmination of there rage and hatred, this merger of souls would be made much easier if Argent D'nur is an alternate earth and DoomSlayer the alternate self of DoomGuy

Towards the end of Doom 2016, we Olivia getting painfully absorbed into some kind of hellish ritual circle, which the Spider Mastermind then crawls out of. This isn't Olivia being transformeded into a new Spider Mastermind, but possibly her being used as a blood sacrifice to resurrect the OLD Spider Mastermind from the original DOOM game. It's been stated in the game that Demons do NOT take kindly to traitors, so it makes sense Olivia would be used as a sacrifice to bring back one of Hell's head honchos.

* [[spoiler:''Eternal'' not only josses this, but confirms the exact opposite - the Doomguy across 1, 2, (maybe) 3, and 64 are ''all'' the Doom Slayer.]]

Due to the constant creature redesigns that have started with ''64'', it is very possible that various demons have numerous differentiating strands with different strengths and weaknesses. Hence this is how both the ''2016'' and ''Eternal'' incarnations of, say, Mancubi can both exist.
Others have simply evolved biologically between the two games, notable ones being Cacodemons and Imps.

* Classic Doomguy was a descendant of William B.J Blazkowics and Billy "Commander Keen" Blaze, whom, during the events of Doom 2, saved his ancestor's souls in the secret levels that resembled Wolfenstein 3D, no doubt a special portion of Hell set aside to torture his ancestors. He was also likely involved in the Plutonia and D64 campaigns, the last of which left him on guard in Hell to ensure no more demons invaded his world. If Classic Doomguy is indeed the protagonist of D2016, he was likely trapped some time after the final battle of D64 and sealed away until Hayden and Pierce unearthed him. If the events of Quake 3 factor into his story, he may have had his armor upgraded by the "traitor of Hell" during the events of Q3 Arena.

He went to hell and back

[[WMG: The Mysterious Figure that helped Doom was the father, who is now Vega.]]

I think the guy who helped Doom in 1:08:37 might be the "Father" character. There might be some shenanigans between him and the Khan Makyr that made him require Doom's assistance. Seems that Vega is the "Father", at 1:23:45 he says "I can... see now... am I the father?". Perhaps something happened to him once Khan Makyr realized what he did? Matti23

[[WMG: Samuel Hayden is getting uploaded into a demon body in the next game.]]
Doom guy already knows about the machine with the Revenant Drones and has used it. It seems that they don't turn you evil, just give you control of the drone. Perhaps the reveal of the drone was foreshadowing? Samuel probably won't stay as the [[spoiler: Doom Fortress' AI because then from a story point of view he may be doubling up the AI role with Vega.]] Using the drone machine to take control of a Revenant would be a good contrast with the other characters and look pretty awesome. The machine is still intact after Doom was finished with it, he just needs another compatible Revenant Drone to load into the machine. He could of course just upload himself into another Robot like before but this is more of a change up. Uploading himself primarily into a Titan or one of the leftover Argent Mechs, although an interesting idea probably won't happen as then he wouldn't be able to fit into many scenes with the Doomguy. Could perhaps be done as a once off though, imagine calling in a Hayden punch like an airstrike. Matti23

* [[spoiler:''Eternal'' not only josses this, but confirms the exact opposite - the Doomguy across 1, 2, 3 and 64 are ''all'' the Doom Slayer.]]

* {{Jossed}} as of ''Doom Eternal.'' [[spoiler: The Betrayer's dialogue with Doomguy right before the latter leaves to find Khan Maykr heavily hints that his son might still be alive, [[MercyKill and that the Slayer needs to stop him once and for all]].]]

The teaser for VideoGame/DoomEternal has confirmed Arachnotrons, Pain Elementals, and Arch-Viles.

** Misguided, perhaps. But these demons could also befriend and support these rebels like The Wretch who made Doomguy's armour. Tensions might arise if Doomguy himself shows up at a rebel camp and scare some demons shitless, leading to some teeth-clenched teamwork between them.

* Revenants are mostly bone with some mechanical servos, decaying organs, and gore. It's not a far stretch that Samuel could have removed the vast majority of his bone body, and if you ever crack open his head you might find a Revenant skull in there. Additionally, the MLRBs would have had to be removed to implant his brain into the robotic body, as they are said to directly interface with the brain via a chip.

Let's put it this way: BrainUploading is a far stretch from the kind of research that has been going in UAC. Chances are, he might be instead reanimated with Lazarus waves. Besides making him appear like a ScienceHero triumphant over death itself rather than a HumanoidAbomination and providing the standard combat perks of PoweredArmor, his shell could be somehow isolating him from the Mastermind's influence... unless he's only thinking he is acting on his own terms and against the greater evil, similarly to [[MassEffect3 The Illusive Man]]. Note that Revenants are explicitly mentioned to be skeletal-thin and very tall, which explains the need for the suit's gigantic proportions. And, of course, a climactic reveal will happen when the doctor transitions into a genuine villain, to cement the point he has been deceptive in more ways than one.

[[WMG: The UAC's Argent Energy is a NecessaryEvil in a scale we haven't seen]]

It's a miracle, but at a [[DealWithTheDevil steep cost]] - it's literally the power of Hell itself which, if it goes out of control, could easily wipe out humanity and [[WellIntentionedExtremist Hayden]] [[NecessaryEvil is fully aware of this fact]]... but it's the only thing that's preventing his home from becoming a barren wasteland. He does whatever is necessary to get Argent Energy but not too dangerously - he has all manner of safeguards in place which, had [[BigBad Olivia]] not screwed everything up, would have been feasible in helping protect mankind.
