[[WMG:The Franchise will be rebooted as a parody of itself.]]
Oh come on, if Duke Nukem ever gets a reboot, you KNOW it will basically be a parody of itself.
* This doesn't seem to be the case if what's been seen of Gearbox's VideoGame/DukeNukemForever is to be believed.
** Also, if what Randy Pitchford said about future Duke games is to be believed, they are going to be DarkerAndEdgier, and definitely not a parody.
*** Not an ''intentional'' parody.

[[WMG:Duke is insane and believes he is an action movie star; the "aliens" he sees and kills are normal people.]]
We only have [[UnreliableNarrator his word for it]] that he's doing what he seems to be, and his speech is so peppered with quotes from other badasses that it's hard to take him seriously as a rational figure.
* Further evidence: He sees the SpaceMarine from VideoGame/{{Doom}} dying. Now, really, what could take out the Berserker Packing Man and a Half, but leave Nukem standing?
* Also, he ''goes to death row''. I have a hard time believing aliens would bother with an electric chair.
* Why would the Pig Cops bother with the Cop shtick? Those are ''actual cops.''
** Mi-go, I could just see it now! You're playing the latest version of Duke Nukem. Generic FPS, shooting bad guys, you and your friend are high-fiving each other when you bring out the shotgun and watch the gratuitous gore go splat. All of a sudden, the entire game changes. You're no longer fighting aliens on a space ship, you're shooting at innocent people in a city. It'll be awesome! It'll piss off everyone! Media guardians will be angry because you'll be killing innocent people and gamers will be angry because all of a sudden the game got preachy (though it only got "preachy" by changing the models, rather than having somebody come on the screen and say "No. That's bad. Violence is terrible.").
** The problem with that is that the aliens have clearly alien goals: namely they've kidnapped women and put them in slime...pod...things preparing to rape them later. If the Pig Cops ''were'' actually human, then that STILL would only make them corrupt psychotic rapist cops with scat fetishes who've taken over LA as their own military state. Unless there is some OTHER reason why "normal" cops would encase women in green shit and sexually assault them. And there is simply no way to explain the smaller slime monsters, the Octobrains, or the fact that if this were the case then Duke Nukem would have to literally be superhuman to take down an entire army so easily. Realistically, and ironically, the "they're aliens, and assholes" answer has fewer logical loopholes. It's possible the Doomguy was sent in ''first'' and Duke is his intended backup, too late to save his comrade unfortunately. An aside: the concept behind the Pig Cops is that they were, at one point, human cops who were mutated by the aliens to be enforcers...so one could still theorize they're "innocents" being killed by Duke, but only in the sense they're normal people enslaved by the aliens. Of course they were still kidnapping women to rape later and encasing them in slime, so they're probably still assholes anyway unless they're being mind-controlled too.
*** To be fair, the smaller slime monsters could just be advanced drones sent after the delusional "Duke Nukem". "Duke" could just be hallucinating them as "monsters". As for the Octobrains, they could simply be mutants with psychic and psionic powers trying to stop the deluded "Duke".
*** As for "Duke" himself, he could just be a delusional SuperSoldier GoneHorriblyWrong.
*** You're forgetting something, the women in the slime pods don't exist, they are a figment Duke's imagination.
*** Alternatively, the so-called "women in the slime pods" are actually hostages of corrupt cops who took advantage of Duke's carnage. And they're actually being restrained with handcuffs made of steel.
*** Also, the "Doomguy" that "Duke" saw could have been a regular marine that "Duke" only imagined as "Doomguy".
*** It might have simply been a generic space marine. The Doomguy was sent with a bunch of them, and they all got killed.
* This is further supported by the fact that parts of DN3D are inspired by ''Film/TheyLive'', the plot of which is that a guy finds sunglasses that make him see the true nature of aliens disguised as people. Coincidentally Duke Nukem himself wears SunglassesAtNight.

[[WMG: Duke Nukem is a cyborg, or a robot.]]
He’s got balls of steel.

[[WMG: Duke Nukem used to be WesternAnimation/JohnnyBravo.]]
When the aliens invaded, Bravo decided it was time to man up and changed his name to Duke.

[[WMG: VideoGame/DukeNukem always has been and always will be a StealthParody of America, sexism, action heroes, and the '90s.]]
It's just so over-the-top nobody takes the series seriously. ''Which is exactly what it wants you to do.'' And one day Duke is just going to come out of the screen to say:
->"Whoa, you thought I was serious about all this?! You're an idiot!"
Oh, and because of [[https://www.youtube.com/watch?feature=player_embedded&v=B9IdrXoTHUg this video.]] Boom, your mind is ''blown''.

[[WMG: Duke is a normal video game in an action movie universe]]
* 'Die Hard'. 'Lethal Weapon'. Duke Nukem is relatively normal compared to these weirdos.

[[WMG:Duke is blind on his right eye.]]
Considering the leak of Duke Nukem Forever 2001, [[FridgeLogic it got me thinking]], why do we only see his left side of the sunglasses? I mean, in one of the cutscenes of ''VideoGame/{{Duke Nukem 3D}}'', Duke puts his sunglasses on, but we see only the left side of it. Duke Nukem Forever 2001 menu is also the left side of SOS. And the [[GameOver game over screen]] from ''VideoGame/DukeNukemForever'' (2011) is also his left side of the sunglasses shattering. The last time we saw Duke without his sunglasses was in ''VideoGame/DukeNukemII'' (1993), as far as I know. Maybe he lost his right eye somewhen along ''VideoGame/DukeNukemII'' and ''VideoGame/{{Duke Nukem 3D}}''? Also, he might not ever take his sunglasses off to [[ClothingConcealedInjury cover it up]]?
