This is when a character has an overwhelming fear of something that someone of their kind just shouldn't be afraid of. For example, a bird who's afraid of heights or a mermaid who's afraid of water.
Often, they get an episode or subplot dedicated to resolving this fear. Almost always Played for Laughs, although there will often be a dramatic moment where they are forced to confront said fear.
These can often be considered Absurd Phobias. May be part of a "What Do They Fear?" Episode. Compare Why Did It Have to Be Snakes?, in which the thing that the character fears pops up at an unexpected and inconvenient moment, rather than being something that constantly confronts them. If a character is afraid of something they are, they're a Boomerang Bigot. If they become the thing that they fear, it's a Karmic Transformation.
- Played for drama and justified in +Anima. Husky and Nana both have phobias that seem to go against their +Anima abilities — Husky is a fish +Anima and afraid of drowning, Nana's a bat +Anima and afraid of the dark. This is because they gained their +Anima powers when their lives were being threatened in those exact positions (Husky was being drowned by a spiteful relative and Nana was being chased by her murderously abusive father through a dark forest).

Later, a new type of clone was created: WORST, who runs on the negative emotions of the Network.

The real irony is that this is probably one of the only emotions she can truly call her own.
- The titular character from Doraemon is a robotic cat, however he is deathly afraid of mice. Justified because a mouse chewed his ears off when he was younger.
- Fire Force: Takeru Noto a.k.a. Juggernaut, like most characters in the series, is a firefighter with pyrokinetic powers. He's also deathly afraid of fire. Paradoxically, he joined the Fire Force precisely to be surrounded by people who could put out fires, including his own.

- In My Hero Academia, Koji Koda, who has the power of speaking with animals, is scared of bugs.

- In one of the Johto episodes, Misty is excited to meet the Nurse Joy who comes from a line of Joys who specialize in treating Water Pokémon... only to discover that this Joy is afraid to even touch Water Pokémon because she hates them so much. Needless to say, as Misty is a Water type specialist, she is not happy in the least.
- Misty herself used to be afraid of Gyarados until she retook her Gym Leader position — normally justified, but given she tends to love all Water Types (notably Tentacruel)...

- On-again off-again Avengers member Wonder Man spent much of his career being horribly afraid of his own death — despite the fact that he's an ageless Energy Being who's in the same tier as Thor or Hercules in terms of raw strength and invulnerability.

- In the Justice Leagueof America: "Tower of Babel" story arc, Aquaman is exposed to a dose of Scarecrow's fear toxin, giving him aquaphobia.
- In Back to Zero, Butch grew up in the aquatic-themed Celadon City yet he fears water.
- In the The Dark Eye fanfic Fünfzig Schattierungen ... ("Fifty Shades ..."), one of the characters is a necromancer who is afraid of the dead. Talk about irony. He's scared in the dark, to the point that he can't go outside alone at night. And yes, it's a parody on Fifty Shades of Grey, and makes about as much sense.
- Penny Polendina in The RWBY Loops has a Trauma Button in the form of Pyrrha Nikos, the warrior who (accidentally) killed her in baseline. Given that she herself was designed to replace front-line warriors, this has quite the effect on her psyche and identity, and is Played for Drama.

- In The Dark Knight Trilogy, Bruce Wayne is afraid of bats. Which is actually the whole reason he decided to pick Batman as his superhero identity in the first place: he wanted to look scary to bad guys, so he went with the scariest thing he could think of.
Alfred: Why bats, Master Wayne?
Bruce: Bats frighten me. It's time my enemies shared my dread.
- Jason Voorhees in Freddy vs. Jason is revealed to be deathly terrified of water, due to him drowning as a child. A fair enough reason in-and-of itself, if not for the fact that his murders often involves him having to wade through/being thrown in large bodies of water. Supplementary material dealt with this by saying it was a deeply buried fear, so buried only Freddy could reach it. Otherwise, he sees water as something to kill people with.
- The Kamen Rider movie Kamen Rider × Kamen Rider Fourze & OOO: Movie War Mega Max introduces Michal Minato, who was supposed to become the water-themed and -powered Kamen Rider Aqua 40 years in the future but was held back by his crippling hydrophobia.

- Ultraman Ginga S The Movie: Showdown! The 10 Ultra Warriors! has the main characters facing physical manifestations of their worst fears when attempting to infiltrate Etelgar's fortress.

- Percy Jackson and the Olympians:
- Thalia Grace has a deathly fear of heights. Her father also happens to be Zeus, lord of the sky.

- In its sequel series, The Heroes of Olympus, Percy himself develops a fear of drowning in spite of being a son of Poseidon with the ability to breathe underwater. It's brought on by nearly suffocating in muskeg and "drowning" metaphorically in expectations and responsibilities.

- The title character of Horatio Hornblower is prone to sea-sickness and he is really afraid of heights. Excellent material for an officer in the Navy, isn't it?

He's also shown trying to fight and overcome his fear voluntarily.

Paris: Sick people freak me out.
Rory: You're pre-med!
Paris: I'm really tired of having that constantly thrown in my face.
- Tamaru from BIONICLE. He lives in a Tree Top Town and wants to be a pilot, but is afraid of heights. Heights relative to a Le-Matoran, that is; the treetops are 'ground-level' to him, so he can leap and swing through the jungle canopy without fear. But he cannot handle flying on birdback, even though he wants to fly more than anything else in the world.
- Teslo, being an Electroid, makes his home in the high mountains to gather electricity from the highest storms. He's also afraid of heights, while also being completely unaware that the other Electroids know this.

- Youmu from Touhou Project is a half-ghost who is afraid of, you guessed it, ghosts. Even more ironic in that her mistress is a ghost, and Youmu has never reacted to that. Youmu is not so much scared of real ghosts as much as she is afraid of ghost stories. Youmu isn't scared of much, but has trouble dealing with scary things. Imaginary horrors are her weakness: in one of the canon manga she fails a test of courage when she keeps fleeing hysterically from people in cheap halloween costumes, even though she was perfectly aware they were false.

- Winston of Freefall was genetically modified for life in space. His modifications make him completely hairless and give him resistance to atrophy in low gravity. Unfortunately, he suffers from an irrational fear of space travel. His phobia is bad enough that when he has to travel on a space craft he has to be kept in hibernation for most of the trip because he is afraid he will go crazy and walk out the airlock.

- Extreme Ghostbusters had a "What Do They Fear?" Episode with a ghost who could make phobias come to life.

- One episode of Franklin has the title character being afraid of sleeping in his shell (which, in this show, it can be taken off) because he's claustrophobic.

- The Owl House:
- Willow is a witch who specializes in plant magic, yet she is afraid of ladybugs (a bug that protects plants by feeding on harmful insects).

- Transformers: Generation 1:
- Silverbolt is afraid of heights, despite being a giant robot capable of transforming into a jet and being the leader of the Autobot's main air squadron, the Aerialbots. Despite this, he proves to be a level-headed, extremely qualified leader who always does his duty. It's specifically why Prime puts him in charge of the team. He says that the demands of the position will give him something to think about instead of his phobia. The fact that he has a sense of caution is also probably a plus, since the other four at that point were all extremely reckless.
- Broadside of the same series gets it twice as bad. He's a triple changer with the vehicle modes of a jet and an aircraft carrier (yeah, yeah, we know), but he's both afraid of heights and gets the robotic equivalent of motion sickness at sea. Mocking his much unenviable lot in life is an infrequent joke among the fandom.

- Transformers: Generation 1:
- Early in Season 2, Stella of Winx Club was shown to be afraid of heights, despite being a fairy. Later, she seemed to overcome it.
