!!The movies in general:
* AlternativeCharacterInterpretation:
** Jason Voorhees, a child stuck in a body of revenant who misses his mother, or a sadistic killing machine who ends his victims in creative ways ForTheEvulz?
** The fifth movie inspired [[Website/{{Cinemassacre}} James Rolfe]] to speculate that the actual Jason never existed and all his appearances were simply a different man in a mask, since his actors and body shapes change so frequently across movies.
* CommonKnowledge:
** Jason never used a {{chainsaw|Good}}, despite the fact that he is often depicted in parody work doing so. In fact, it is the preferred weapon of [[Franchise/TheTexasChainsawMassacre Leatherface]]. Jason's canonical weapon of choice is his machete.
*** To the point that one of the most in-character actions of ''Jason X'' is him hunting for his machete for the first third of the film and abandoning the future machete he's been using up until that point when he retrieves it.
*** In ''The New Blood'' Jason did use a gas powered underbrush cutter on one of his victims. Not a chainsaw, but still...
*** In fact, the only time an actual chainsaw is used in the series is when one is used ''against'' Jason and it runs out of gas before he or the survivor can put it to any real use.
** Some people think Jason only ever walks, which is true for the second half of his films, however in the earlier movies he was shown running fairly frequently.
* DracoInLeatherPants: A lot of people take Jason' CrazySurvivalist KnightTemplar EvenBadMenLoveTheirMamas angle and ''run with it''. He has an astonishing amount of fanfiction where he falls in love with the one girl who he doesn't kill. Frequently going through {{Wimpification}} and becoming a literate mentally sound gentleman who just ''happens'' to go on mindless merciless killing sprees every now and then.
* EnsembleDarkhorse:
** A few minor characters proved quite popular among fans. Some examples would be Crazy Ralph from the first two films, and Violet from ''A New Beginning''.
** The most popular character of the series, however, is hands down Ginny Field. In fact, she's so popular she often places in "Best Final Girls Ever" lists.
* {{Fanon}}: Absolutely zero official sources have bothered to comment on the nearly unanimous fan theory that ''Film/JasonX'' takes place after ''Film/FreddyVsJason'', despite being released before it. Regardless, it remains a nearly unanimous fan theory, because it just makes the most sense.
* GermansLoveDavidHasselhoff: The series has a pretty big Japanese following.
* IconicCharacterForgottenTitle: While the "Friday the 13th" title is hardly forgotten, people do have a tendency to refer to the movies as "the Jason films" more often than their primarily title, which makes things interesting as [[spoiler: Jason isn't even the killer in Parts 1 ''or'' 5.]] Not helping is the fact that the New Line Films, barring the reboot, do explicitly have Jason as part of the main title for each movie rather than "Friday the 13th."
* ItsTheSameNowItSucks: Parts two to four can come off as this, as they all have very similar plot structure. Later films get more creative with their presentation, though some of them are disliked for getting ''[[TheyChangedItNowItSucks too]]'' creative.
* JerkassWoobie: Jason. Yes, he's a psychotic murderer and should obviously be met with scorn than pity, but the man is only acting out because of his mother, the only person who cared about him.
* SugarWiki/MostWonderfulSound: Jason's leitmotif (''ki-ki-ki-ma-ma-ma'').
* NarmCharm: The majority of ''Jason X'', if not the series as a whole.
* NightmareRetardant: Jason's status as a often referenced pop culture icon has turned him into this. Kind of ironic, really. [[FridgeLogic Think about it:]] if, in RealLife, you found yourself being pursued by a relentless, pissed-off, virtually indestructible mass murderer who was built like a pro athlete and wanted nothing more than to bury a machete in your head, wouldn't you be just a little bit scared?
* RootingForTheEmpire: Most of the protagonists in these films are too boring or unlikeable to care about, so who ''wouldn't'' want Jason to kill them all off?
** This typically comes into play from the fourth film onwards. The third film has elements of it, but they're still a minor compared to the relatively decent, likeable protagonists -- we have three random bike gang scum types, and one obnoxi ous practical jokester (who admits he only does so because he's a fat nerdy loser type and it's the only way he can think of to make people like him), compared to a pregnant woman and her loving boyfriend; two friendly, quiet-natured hippies; and a traumatized girl with her boyfriend, who tries to understand why she's such a wreck. And in the first two films, the counselors are generally pleasant, affable folk, who only count as jerkasses because they see nothing wrong with smoking, drinking or premarital sex.
* {{Sequelitis}}: With 10+ films, it was bound to happen.
* TheyChangedItNowItSucks: ''A New Beginning'' (for [[spoiler:Jason being replaced by a copycat killer]]), ''Jason Takes Manhattan'' (for changing the setting to a cruise ship and then to a big city), ''Jason Goes to Hell'' (for turning Jason into a body-hopping demon), ''Jason X'' (for sending Jason to a campy adventure in space), and the 2009 reboot are often victims of this.
* WhatAnIdiot: Why did Jason bother going into the lake if he couldn't swim, anyway? Admittedly, he was running away from his tormentors in a panic, but surely he could have run into the woods, which he knew much better?
** Key words there; he was being chased and he was panicked. People don't think too well in that kind of situation to begin with, little kids moreso, and add in the fact Jason was born mentally deficient...

!!The NES video game:
* HilariousInHindsight: [[Film/TheDarkKnight "You and your friends are dead."]]
* ParanoiaFuel: Jason could occasionally show up unannounced inside one of the cabins that you were investigating for items and notes. And once you're inside with him, you're locked in until you face him.
* TheProblemWithLicensedGames: It's very difficult, it's very easy to get lost, and Jason constantly pops up to kill off counselors and children when you're in the middle of doing something.

!!The novels:
* CompleteMonster: In ''The Jason Strain'', Caleb Carson is a [[CorruptCorporateExecutive television producer]] who has a team of mercenaries at his beck and call. He has them gleefully murder people who get in his way, and it's revealed that he [[FrameUp framed the main character]] for a brutal double homicide just so he would end up in prison and become one of the {{Condemned Contestant}}s on his BloodSport [[DeadlyGame reality show]]. He was also [[ItMakesSenseInContext willing to cause]] a global ZombieApocalypse rather than have to cancel his show.
