** During the invention exchange for "The Giant Gila Monster", Dr. Forrester shows off a line of [[https://www.youtube.com/watch?v=t0qY3OMT99I&ab_channel=CaptainMatticus Renaissance Fair punching bags]], which prompts TV's Frank invoke this trope.

* In the ''Series/MysteryScienceTheater3000'' episode "Teenage Caveman" the bots have a squirrel say this to the title character when he has rather more trouble catching than he should.

Here is a [[https://www.youtube.com/watch?v=4cxn2rC0x-k compilation]] with a lot of examples of this quote.

Not to be confused with YourWorstNightmare (which is about actual nightmares).

* [[http://www.brunothebandit.com/d/19990511.html This]] ''Webcomic/BrunoTheBandit'' strip.

** ''WesternAnimation/BatmanTheAnimatedSeries'': Batman replies with this when a terrified criminal asks "Who are you?!" in [[https://www.youtube.com/watch?v=xDP8zru0FPE episode 5, ''Pretty Poison.'']]

* In ''WesternAnimation/TheLorax'', O'Hare warns Ted that if the boy doesn't stop trying to find out about trees, he'll become his worst nightmare. Which, in his view, is Frankenstein's head on a spider's body.

* Franchise/{{Batman}} often uses this phrase when a criminal asks what he is.
* Superman from the New 52 Action Comics: "Rats, rats with money. And rats with guns, I'm your worst nightmare!"
* ''ComicBook/TheSandman'''s Merv Pumpkinhead: "Lady, I'm your worst nightmare. A pumpkin with a gun." Justified, as Merv is a literal nightmare. Which is based on the infamous subplot from Steve Gerber's run on ''ComicBook/TheDefenders'': "I'm your worst nightmare. An elf with a gun!"
* Used as a joke in a Frank and Ernest strip where Ernest is being chased by a giant sausage that says: "I'm your WURST nightmare!"
* ComicBook/GreenLantern (Kyle Rayner) to a group of alien invaders in ComicBook/JLA1997: "I'm your worst nightmare. A [[AscendedFanboy Manga nut]] with a [[ImaginationBasedSuperpower power ring!]]"

* Mysterio uses this during a robbery in the 2019 ''Symbiote Spider-Man'' series.

* ''Fanfic/TheUltimateEvil'': after [[WesternAnimation/JackieChanAdventures Shendu]] is freed from his imprisonment as per the first season's plot and he [[VillainousCrush kidnaps Valerie Payne]], he introduces himself to her this way.
--> "There are more things in this world then you can ever imagine. Monsters lurking in the dark, shadows waiting to be unleashed; [[AllMythsAreTrue all the fairy tales you humans now tell yourselves to be myth, were once]] ''[[AllMythsAreTrue very]]'' [[AllMythsAreTrue real]]. They wait, lurking in the unseen corners, waiting until you turn your back and then - ''(smashes a stone next to Valerie)'' - They'll strike. But of all the dangers, I am the most powerful, none dare resist the will of [[IAmTheNoun the]] great and powerful Shendu!"

* ''Film/FortyEightHours'':

* Sidorio from ''Literature/{{Vampirates}}'' [[BadassBoast describes himself]] as the sort of thing your worst nightmares "[[UpToEleven wake up screaming about]]."

* Parodied in ''[[FanFic/TantabusMarkII How the Tantabus Parses Sleep]]'' when DreamWeaver Moondog jokingly introduces itself to Stygian with this phrase, only to give a LongList of times when this isn't the case, which quickly amounts to it never being his worst nightmare.

* Lo Wang, the ''ShadowWarrior'', is everybody's worst nightmare, at least according to himself.

* In ''Videogame/DynastyWarriors 8'', We have Li Dian, who is the most awkward member of Wei. He makes impromptu FreudianSlip {{Love Confession}}s (regardless of the PlayerCharacter's sex) as his praise quote if he's an allied officer and the player is performing well. and [[InvokedTrope introduces himself]] with ''"I am Li Dian, your worst nightmare!"'' if you encounter him as an enemy (and you are not playing as [[HeterosexualLifePartners Yue Jin]]).
* Downplayed in ''VideoGame/{{Undertale}}''. The final boss of the neutral route, [[spoiler:Photoshop Flowey]], is accompanied by a track entitled "Your Best Nightmare". Considering exactly what [[spoiler:Photoshop Flowey]] [[{{EldritchAbomination}} looks like,]] it's justified. It also ties in with [[spoiler:Flowey's normal theme]], "Your Best Friend".

** In ''Literature/{{Snuff}}'', Vimes makes Stinky the goblin a Special Constable, and Stinky responds to Vimes' quip that someone's worst nightmare is "a goblin with a badge" with "Stinky don’t need no badges, fellow po-leess-maan! Stinky worst nightmare all by himself!"

* ComicBook/GreenLantern (Kyle Rayner) to a group of alien invaders in ComicBook/{{JLA}}: "I'm your worst nightmare. A [[AscendedFanboy Manga nut]] with a [[ImaginationBasedSuperpower power ring!]]"

-->'''The Doctor:''' I am a ''complex space-time event.'' I am Lord President of Gallifrey, the traveler from beyond time. I am the ''Sandman'', [[Characters/DoctorWhoTenthDoctor The Oncoming Storm]]. I am the Ka Faraq Gatri, [[PlanetDestroyer Destroyer of Worlds]]. And sometimes... ''only'' sometimes... '''I am your worst nightmare.'''

* "Welcome to the castle of nightmares! I'm your greatest nightmare!" So says the FinalBoss of ''VideoGame/CastleOfShikigami 3''.

* This is said in the finale of ''WesternAnimation/{{Mulan}}'' by Mushu to the fireworks operators so he can use fireworks to beat Shan Yu. Depending on who you ask, this is either a ''Batman'' reference, or it refers to ''48 Hours'', where Eddie Murphy actually says the quote, making it a self-reference.

* Occurs in ''Film/RamboIII''.

* Spoofed in ''Film/CanadianBacon'': The main characters use the line on a Canadian, only for the character to whom they say the line to describe their actual worst nightmare.
