 * In Ouran High School Host Club, the club members try to scare Haruhi and fail.
 * Ranma ½'s Ranma has one of these. They find out that.
 * Similarly, Inuyasha also has an episode dedicated to this trope, in which the whole main cast is trapped and forced to see their worst fears.
 * An early episode of Galaxy Angel revealed that Forte is deathly afraid of (and allergic to) rodents. Despite Normad's clear intent to use this for blackmail, it's never brought up again in the anime.
 * Yusei of Yu-Gi-Oh! 5D's is practically crippled by fear after losing his duel with Kiryu (once his best friend and Big Brother Mentor now brought Back From the Dead -- which Yusei blames himself for -- and psychotically evil), as if he's so unfamiliar with the emotion, he has no idea how to deal with it (dialogue Dub Induced Plot Holes regarding visually non-existent entomophobia aside).
 * In an episode of Ronin Warriors, Dais revealed to Kento that the more he used his Hardrock Armor, the more bloodlust he would experience. Instead of being able to use the armor for good, he would use it for evil. For a while, Kento was afraid to summon his full armor in fear of hurting his loved ones.

Comic Books

 * Subverted in the Batman storyline Knightfall. The Scarecrow turns his toxin on The Joker to discover what he fears. The answer:.
 * In the same storyline, Batman's biggest fear is revealed to be Jason Todd's death - which already happened. Cue Unstoppable Rage at Joker.
 * Really, this happens to everyone, heroes and villains, who comes into contact with fear gas. Bats has also been beaten with memories of his parents' deaths (in both The Long Halloween and Batman: Arkham Asylum); Catwoman had a good ol' wrestle with her relationship with Batman in Catwoman: When In Rome; and the Riddler is shit-scared of the Joker. (But then, so is half the DC universe.)
 * Incidentally, if Blackest Night is to be believed, the only thing that scares Scarecrow is Batman. Literally, the only thing - using his fear gas so much has made Scarecrow not just immune to its effects but to feeling fear period. Except, as stated, the fear of Batman, to which there is no immunity.
 * A crossover with Judge Dredd had Scarecrow using his fear gas on Judge Death. It seems Death is afraid of plushies.
 * This summer's Captain America/Thor centric Marvel Crisis Crossover Fear Itself looks to be one of these. The main plot involves Red Skull find the hammer of and resurrecting the spirit of the long dead of the Norse fear god. In the first issue as soon as Odin becomes aware of this he immediately tells Thor and the rest of Asgardians to pack their bags because they're leaving earth while they're still alive. Also, solicitations for tie-ins seem to indicate that there will be a lot of stories featuring the heroes of the Marvel universe facing their deepest fears head on.
 * In Elf Quest's Trial of Head, Hand and Heart arc, the Trial of Heart involves Savah mind-probing Cutter and Rayek to learn their deepest fears, and then setting challenges to see whether they can overcome them. The twist is that Cutter's challenge turns out to be Rayek's as well.

Literature

 * Harry Potter and The Prisoner of Azkaban has the third-year Defense Against the Dark Arts students taking on a boggart, a Shapeshifting creature which can take on the form of whatever its viewer fears the most. This provides a pretty funny chapter in which the students conquer the boggart by using the Riddikulus spell to turn it into something laughable, but it also shows the reader what some of the students fear most. Hermione, during her final exam, is terrified by her boggart, whose appearance (Professor McGonagall telling her she failed all of her classes) illustrates her deep-rooted fear of failure; Harry, by comparison, sees Dementors when he faces boggarts, which Professor Lupin says means that what he fears most is fear itself.
 * There is a Tear Jerker echo much closer to the end of the series where Mama Bear Molly Weasley confronts a boggart who turns into her biggest fear - the dead forms of her beloved husband, her children, and Harry.

 * Buffy the Vampire Slayer: Fear Itself, as well as "Nightmares" in Season One.
 * The season four finale "Restless" had this element too, being centered another dream episode (Willow gets her old stagefright dream from "Nightmares" combined with a scene where Buffy "unmasks" her as the timid girl she used to be, while Xander is berated by his father). There is a Call Back to "Nightmares" when Willow hopes that they are not performing "Madame Butterfly".
 * One episode of Doctor Who during the Third Doctor's tenure, The Mind of Evil, had him encounter a mental parasite that projected its victim's worst fear. His was the horrific memory of seeing a world burst into flames (from the serial Inferno). Later, the Master fell victim to it - his worse fear is the Doctor laughing at him.
 * The Eleventh Doctor also had an episode of this, The God Complex. His worst fear is not shown, but the audience can hear the Cloister Bell ringing; and when he sees it, he is not surprised.

 * Samurai Sentai Shinkenger does an episode in which Sixth Ranger Genta develops a crippling phobia of sushi after the events of the previous episode. Each of the other teammates confronts his or her own fear, some of which (Ryuunosuke's fear of cacti after sitting on one as a kid) are lamer than others (Takeru's fear of horror houses, which causes him to faint).
 * Several episodes of Maury have guests who fear really odd and crazy things, ranging from balloons, pickles, cotton balls, birds, mustard, peaches, and other things. Usually played at the expense of the guests where Maury brings out the stuff they fear and they go running scared for a while.
 * Sort of used in the M*A*S*H episode "Dreams", which feature the main characters' nightmares — all of which are highly tailored to the characters' histories and psyches.

 * Happens in Justice League, when Doctor Destiny sticks the core seven into their own worst nightmares. Superman was afraid of his powers going out of control and killing all his loved ones. Hawkgirl is trapped in a coffin and buried alive (this was foreshadowed earlier in the episode). Flash fears that he would run so fast that the rest of the world would freeze in time. Green Lantern is afraid that he was becoming nothing more than a tool for a ring, and losing touch with where he came from--reflected in people being afraid of him and being unable to communicate with him, as though it were just another of the alien worlds he's been tasked to protect. Batman cheats--despite telling Dr Destiny how "My mind is not a nice place to be" he just chugs coffee and stays awake until he takes him down, so we never do find out what he fears.

 * One time it was subverted; the Scarecrow made a gas which removed fear; causing people to engage in reckless and dangerous behaviors, putting the lives and limbs of themselves and others in danger. Unfortunately for Crane, this also removed Batman's aversion to using excessive force--he wasn't afraid of what killing a criminal would do to him...
 * Him once found out what each of The Powerpuff Girls feared the most and exploited them in a literal Your Worst Nightmare plot: Blossom, the leader, is afraid of failure (represented by failure in school); Bubbles is afraid of the dark, as had been seen before; and Buttercup, a la Raven, so vehemently prides herself on fearing nothing that the sisters' mutual minor fear of bugs and spiders makes her feel completely powerless.
 * The Dungeons and Dragons episode "Quest of the Skeleton Warrior" was one of these; the bulk of the episode was devoted to exploring the kids' fears to the point where the Skeleton Warrior himself pretty much got demoted to a walk-on.
 * An episode of Xiaolin Showdown did this; it consisted of Jack Spicer breaking into the Xiaolin temple and swiping a certain Shen Gong Wu that allowed him to enter the minds of the four main protagonists and find out what scared each of them the most.

Also Slimer is terrified of... broccoli.
