* AwesomeEgo: Duke is a self-centered, politically incorrect chauvinist bastard. And the fans love him for it, both in and out of universe.
** ''VideoGame/DukeNukemII'' explicitly says that he's so vain that he likes to collect his own memorabilia (which is a primary source of points in the game.)
* CrowningMomentOfAwesome: In ''Land of Babes'', despite being non-canon, at some point Duke is repopulating Earth, by having almost non-stop sex with all females that remained after all males were killed.
* HellIsThatNoise: The siren in ''Duke Nukem Advance''. Even worse, [[ParanoiaFuel it doubles as]] CriticalAnnoyance.
* MemeticBadass: Take a guess who. Just look at him!
