History WMG / Doom

After the trauma experienced due to the invasion of Mars, Doomguy adopted Daisy as an emotional support pet to help him deal with the mental effects of those events.

* [[VideoGame/SuperMarioBros Super Mario is Doomguy]], and Bowser and his minions were demons the whole time.

Think about it - why else would the Icon be a head on a wall? It was probably integrated into Hell's center, hence the biomechanical look and the fact that its "thrashing limbs" were never seen, meaning its body was probably inside the walls. [[spoiler:Only after a hundred years of evolution and architecture changes would the Icon of Sin finally get to roam freely.]]

After Scott escaped I.M. Meen's labyrinth, I.M. Meen swore that he would be back. Eventually, he died and went to Hell, where, with the Harbinger of Doom, they planned revenge on Scott, who is [[spoiler:BJ Blazcowicz's grandson.]] The Harbinger of Doom's powers helped all of I.M. Meen's monsters TakeALevelInBadass, thus transforming them all into the Doom monsters we know (Troll=Demon, Spider=Arachnotron, Grim Reaper guy=Revenant, Guardian=Baron of Hell, Red ghost thing=Cacodemon, etc.), and so that they [[WeaksauceWeakness didn't go down in a few punches from a little kid.]] Scott happened to get a job on Phobos, and I.M. Meen saw it as a perfect time to unleash his new hellish army, which proceeded to zombify all the humans. Unfortunately for him, Scott also TookALevelInBadass and was easily able to defeat the demons, thus foiling I.M. Meen... or so he thought. His anger had turned him into the Icon of Sin, and the demons invaded Earth. Eventually, Scott defeated I.M. Meen for the last time, bringing peace to Earth. [[BrotherChuck Although it does make me wonder what happened to Katie (the girl).]]
* perhaps Katie is the second person on the cover!

McNeil says "Welcome Home", not "Welcome to a better place", or "paradise", or any other euphanism for Heaven. This would indicate that the Marine somehow survived and got back. Previously, there was an issue with this WMG because the Marine had no way to return to Mars, considering the teleporter he used had had no opposite teleporter in Hell, which would prevent any return trip. However, the Exis Teleporter solves this. It has been shown to be capable of being activated within Hell (which makes up the plot for the Lost Mission) so the Marine somehow fought his way to that teleporter and escaped back to Mars and then to Earth with Dr. McNeil. The demons also won't be able to follow them, because the teleporters require someone who knows how they work to maintain the portal (which are the roles of Ian McKormic, Dr. Meyes and Dr. McNeil when teleporting the main character. Not having a proper overseer destroys the Delta Teleporter when the Marine came back in Doom 3). The demons, in order to activate the teleporter, required Betruger to maintain the portal (who, at this moment, is kind of dead). They wouldn't be able to operate the teleporter without him, finally fully severing all direct ties between Hell and our universe.
