YMMV: Duke Nukem
- Awesome Ego: Duke is a self-centered, politically incorrect chauvinist bastard. And the fans love him for it, both in and out of universe.
- Duke Nukem II 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.)
- Crowning Moment of Awesome: 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.
- Hell Is That Noise: The siren in Duke Nukem Advance. Even worse, it doubles as Critical Annoyance.
- Memetic Badass: Take a guess who. Just look at him!
