Created by Creator/SteveDitko, the Creeper first appeared in ''"Showcase''" #73 (April, 1968). He went on to star in his own short-lived magazine, suffered a couple of [[Main/RetCon retcons]] and [[Main/ReVision revisions]], and has done some guest appearances, never quite achieving wide popularity.

The original story tells about Jack Ryder, a Gotham City talk host who tries to save a scientist named Dr. Yatz from mobsters. An attempt to sneak in to the boss' mansion in probably one of the weirdest outfits ever, where Dr. Yatz was held during a masquerade, only got Ryder wounded and saved by Dr. Yatz who implanted him with a device that could make his costume disappear and with a serum that gave him super strength and agility, as well as the power to [[Main/HealingFactor heal almost instantly]]. It's also mentioned that his laughter makes people nervous or is even physically painful. Ryder could activate the suit (and apparently the superpowers, too, since he mentions not being so fast and strong in his normal form) whenever he wanted with a [[HammerSpace button-like object]].

Depending on the series, Creeper either acts like Ryder or is happily insane. Some versions explain the insanity by stating that he had a drug of some sort in his system at the time he had the device inserted, so the narcotic is recreated along with the costume.

The Creeper is also remarkable in being pretty much the only character ComicBook/TheJoker [[HorrifyingTheHorror fears]], which is one ''hell'' of an accomplishment.

[[IThoughtItMeant No relation]] to the walking green timebombs from ''VideoGame/{{Minecraft}}'', or the hunched-over hulk who constantly shouts PAPER from ''Franchise/ScoobyDoo'', or the monster from ''Film/JeepersCreepers''.

'''NOTE: Tropes specific for his version from ''WesternAnimation/BatmanTheAnimatedSeries'' go [[Characters/BatmanTheAnimatedSeriesAllies here]].'''

!!This character provides examples of:

* ActionGirl: Fran definitely wasn't left out when the gang fought against Disruptor's men.
* AdaptationalVillainy: His ComicBook/{{New 52}} version is very much demonic, and even gets a VillainEpisode in ''ComicBook/JusticeLeagueDark'' during the ''ComicBook/ForeverEvil'' event. As part of DC Rebirth, Jack Ryder appears to be back to his original pre-New 52 version from before.
* BrownNote: DependingOnTheWriter, the Creeper's laugh can shatter anything from nerves to bones.
* TheCameo: Aside from his many appearances in the comics as both Jack Ryder and the Creeper alike, he figures into animated continuities as this such as ''Batman: The Brave and the Bold'' and, most memorably, the DCAU.
** Jack Ryder's voice can be heard on a radio on VideoGame/BatmanArkhamAsylum, and he appears as a minor supporting character in VideoGame/BatmanArkhamCity. One of the tapes unlocked by talking to Quincey in the church makes it clear that the Creeper and Huntress exist.
** He is also the source of a lot of discoverables in ''VideoGame/DCUniverseOnline'', but he never turns into the Creeper.
* CampStraight: The Creeper has a rather flamboyant personality and outfit, but Ryder's only dated women.
* CrazyEnoughToWork: His insanity gives him the ability to come up with bizarrely irrational but effective plans. He stopped a prison riot a jailbreak at Arkham by inciting a riot between the inmates.
* CreepyGood: The guy is so batshit loco that even ''ComicBook/TheJoker'' considers him a lunatic! The Joker actually ''fears'' him. Let us reiterate that: THE MonsterClown of comics who terrifies millions has nightmares about ''this'' guy.
* DidYouJustPunchOutCthulhu: When Hush posed as Bruce Wayne in the comics following Batman’s apparent death, Batman's friends and allies displayed a "show of force" to demonstrate how easily they could stop him if he tried anything. Most of them just block his path when he tries to escape ([[ComicBook/BatmanAndTheOutsiders Katana]] going so far as to hold a sword to his throat), but the Creeper ''picks him up like a doll and throws him across the room''. Later, he's seen in disguise personally babysitting Hush at work.
* DramaticPause: ''I heard you guys worked for, [[SayingSoundEffectsOutLoud dramatic pause]], ComicBook/TheJoker!''
* EveryoneHasStandards: The Joker (yeah, [[ComicBook/TheJoker that one]]) thinks he's uncontrollably insane, and wants the Creeper to get away from him, so it's more like "Even Insanity Has Standards."
* EvilLaugh: The New52 version.
* {{Expy}}:
** The Creeper's resemblance to Batman foe The Joker (both have green hair, clownlike faces and maniacal laughter) first pointed out in an issue of the latter's own comic book in the 1970's (where the two fought) may have led to the character's reinterpretation as being insane.
** These days his "Jack Ryder" persona seems to make a growing resemblance in appearance and attitude to tv personalities Creator/StephenColbert or [[Series/TheOReillyFactor Bill O'Reilly]]
* FluffyFashionFeathers: The costume, famously, incorporates a ''giant red feather boa''.
* FullFrontalAssault: Not quite, but close. Part of the reason he's so terrifying to enemies is that he's literally wearing just a thong and booties.
* FunPersonified: Imagine the Joker in one of his wacky phases... ''as a good guy.'' Including the part where [[BewareTheSillyOnes wackiness doesn't mean not being good at what you do]].
* FutureBadass: A dystopian future that ComicBook/CaptainAtom appears in, during ComicBook/BrightestDay shows The Creeper still alive over 100 years later as a cyborg, and as noted, still insane.
* HappyRain: In one story he ponders how he's always enjoyed being in the rain, and as Ryder even doing news reports during blizzards and typhoons.
%%* HealingFactor
* HellIsThatNoise: His laughter is depicted as this for his enemies, triggering primal fear or even inducing deep psychological problems.
%%* HeroWithBadPublicity
* HeroesWantRedHeads: At least this is what Ryder's ex [[MistakenForCheating seems to think]]. ''"Switching from blondes to redheads now, you son-of-a--"''
* ImpracticallyFancyOutfit: In the original comics the costume was actually a full suit, the yellow part being spandex or similar (and it was also the last suit available in the shop), the hair being a wig, and the cape being made from an old rug that the costume shop cashier threw in. It was also recognized to be a costume by some criminals, but since the doctor's device makes the costume stick like glue, trying to pull the wig off with no effect made them realize it to be the "real deal".
* IntrepidReporter: So much that he slips into jerkass territory now and then. He hosts a talk show called ''You Are WRONG!'', not to say anything of the guest stars he has on just for the sake of deliberately antagonizing them.
* InvoluntaryShapeshifting: Jack Ryder spent the good portion of one comic book spontaneously half-transforming into the Creeper without any control. His attempts to make himself scarce in the presence of his co-workers were entertaining.
* JerkWithAHeartOfGold: In spite of his assholish tendencies with his fellow reporters, he’s shown to genuinely care where it counts when ex-girlfriend Vicki Vale approaches him for advice on whether or not it’s ethical to publish an incriminating story that could ruin someone’s life.
* LargeHam: He purposefully invokes this in his original Ditko incarnation, in order to terrify criminals into submission. [[{{Flanderization}} All subsequent versions]], though, have portrayed the Creeper persona as being [[CloudCuckoolander genuinely out of his gourd]].
* LaughingMad: Sort of. His wild laughter made criminals extremely paranoid and nearly insane.
* LockingMacGyverInTheStoreCupboard: The very first comic origin.
%%* TheMadHatter
%%* MagicPants
* MakeMeWannaShout: DependingOnTheWriter, his laugh can range from a deadly sonic weapon to [[TheHyena just plain annoying]].
* NoCelebritiesWereHarmed: A rare unintentional example. Jack Ryder is a [[Creator/StephenColbert black haired, caucasian reporter,]] who, as noted in the StrawmanPolitical entry, is a left-wing political pundit, with a [[Series/TheColbertReport TV show that parodies right-wing political pundits]]. In a meta-sense, both were supporting characters for [[Franchise/{{Batman}} someone]] [[Series/TheDailyShow else]], whose popularity rose significantly from one or more TV appearances. Also, Google 'Stephen Colbert smiling', we'll wait.
* OurDemonsAreDifferent: [[spoiler: His Creeper side has been revealed to be demonic in nature.]]
%%* SlasherSmile
* PlotHole: Steve Niles's {{Retcon}} explains the change with nanocells, but the fact that Ryder can change to Creeper (who has his own set of "clothes") and back and still have his [[Main/MagicPants normal clothes]] is never explained or even lampshaded.
* RummageSaleReject: [[http://ifanboy.com/articles/dc-histories-the-creeper/ Literally]]. Ryder put together his costume with ten dollars of leftover costume parts, including a sheepskin rug for a cape.
* ScrewySquirrel: Sometimes.
* SplitPersonality: Suffers from this [[DependingOnTheWriter depending on the story]].
* StrawmanPolitical: In pre-ComicBook/{{New 52}} continuity, Jack Ryder was a very outspoken left-wing pundit, whose show was called ''You Are WRONG!'' Though he did start to mellow a bit after becoming the Creeper.
* {{Stripperiffic}}: RareMaleExample. His costume consists of a green speedo, red boots and gloves, and a giant, fluffy red boa. In the 2006 miniseries, the costume naturally grows on his body as another side effect of the nanocell technology with the “boa” resembling some sort of organic, tendon-like [[BodyHorror growth]].
%%* SuperSerum
* TalkativeLoon: The Creeper is [[MotorMouth not a quiet or reserved individual]], as [[YouFightLikeACow anyone who has tried to fight him will attest]].
* TerrorHero: Creeper used to pull a scare shtick by pretending he was not human, describing the horrible fates of his enemies, laughing and acting weirdly to make his enemies panic (and loving every minute of it). This worked well enough that he actually managed to make one less hard-boiled guy faint. He even managed to make Scarecrow briefly recoil in fright while visiting him in his cell at Arkham.
* TooKinkyToTorture: Or insane at least, as is found out when he's tortured to test his pain threshold.
* UnderwearOfPower: As part of his {{Stripperiffic}} outfit.
%%* WallCrawl
* WeatherControlMachine: Dr. Storme's weather rod.
* YoureInsane: Almost all times when doing something with (or near) other heroes and is usually treated with [[InsultBackfire "Yeah... Ain't it cool?"]] Also, need we remind you that the JOKER called him a lunatic?
