Characters / Friendship Is Magic: Dangerous Creatures

They don't pose as much threat as the Big Bads, nor do they actively seek to conquer or destroy Equestria and ponykind (though for some of them their behaviors could have that consequence), but they still pose a threat. They are criminals, malicious types, dangerous fauna, and forces of nature.

    Ursa Minor and Major
Do not disturb.
Debut: "Boast Busters"

Ursa Majors are titanic beasts with fearsome reputations that the magician Trixie claimed to be able to defeat so as to gain popularity... which resulted in two colts luring a real Ursa to town for Trixie to defeat. Turns out they had the wrong animal — the building-sized monster they found was an Ursa Minor, a baby. Adult Majors are much, much bigger.

  • Animalistic Abomination: They're bears. Except they're the size of buildings, grow to be the size of hills, and are quite literally made out of stars.
  • Bears are Bad News: Especially when they’re the size of a two-story building and in a bad mood from being just woken up.
  • Celestial Body: They provide the current page picture. The Ursa Major is a bit unusual in that it is a deep purple, instead of the standard indigo, black or blue.
  • Constellations: They're essentially puns on the real life constellations Ursa Minor and Ursa Major, the Little Bear (which includes the North Star) and the Big Bear (mostly made of the Big Dipper).
  • The Dreaded: Ursa Majors seem to have this reputation. Trixie claiming to have beaten one gets her a lot of attention, and in the end she admits that nothing can defeat an Ursa Major.
  • Eldritch Abomination: In a sense, they are very much this. The Minor is a huge blue Energy Being bear that is easily bigger than a house. Its parent, the Major, is a purple, fanged and even larger monster than the Minor, and there are strong implications that the Minor is still an infant. They don't even look like regular animals so much as pieces of the night sky in the shape of bears.
  • Energy Being: They may be this, given that they seem to be made of stars and the night sky rather than flesh and bone.
  • Lovecraft Lite: The Ursa Minor. It's a gargantuan bear made of stars and it's only going to get bigger and more dangerous with time, but looking at it doesn't drive anypony into insanity, and it was stopped from destroying the town thanks to Twilight Sparkle giving it a bottle.
  • Music Soothes the Savage Beast: Twilight's first move against the Ursa Minor is to create a wind that produces music by blowing through cattails, seriously mellowing out the monster.
  • Non-Malicious Monster: The Ursa Minor only went into a rampage because of Snips and Snails disturbing it from its sleep.
  • Rent-a-Zilla: The Ursa Minor is a bear quite a bit larger than most buildings in Ponyville. The Major is quite likely the single biggest animal in the show.

Basil (Bottom Left), Reginald (Right), and Teenage Dragons (Top)
Red Adult Dragon's Debut: "Dragonshy"
Green Adult Dragon's Debut: "Owl's Well That Ends Well"
Other Dragons' Debut: "Dragon Quest"

Voiced by: Vincent Tong (Garble)note , Ashleigh Ball (one dragon in "Dragon Quest")note , Matt Hill (Spear), and Richard Ian Cox (Clump), Blu Mankuma (Basil), Scott McNeil (Reginald)

Over the course of the series, dragons of various sizes, colors, and personalities have appeared, usually playing the role of an antagonist. How bad they are, however, depends on the episode and the dragon(s) in question.

For tropes relating to Garble specifically, see Friendship Is Magic: Jerks and Bullies.

  • Always Chaotic Evil: Zig-zagged. While most of them are apparently inherently aggressive, greedy monsters with a disdain for weaker beings like in Scandinavian myths, they'd rather spend all day napping in their lairs and never seem to go out of their way to torment ponies.
  • Ambiguous Gender: Crackle has eyelashes, but "Crackle's cousin" (Twilight Sparkle, Rainbow Dash and Rarity in a dragon costume that also has eyelashes), is assumed to be male by the purple teenage dragon. The other dragons might have not noticed the eyelashes on the costume.
  • Attack of the 50-Foot Whatever: The full-grown dragons are huge; the average-sized pony is smaller than their head.
  • Bizarre Alien Biology: Aside from breathing fire, they eat gems, have anywhere from ten to four limbs, retractable thagomizers, belly buttons, and head decorations ranging from horns to hair to, in Spike's case, what seems to be a green rooster's combnote . They don't all have that full list of features, so this is also a case of bizarrely wide morphism.
  • Blinding Bangs: The purple teenage dragon has these... which may bring up some questions.
  • Breath Weapon: As expected, they can all breathe fire, which can be of varying colors.
  • The Bully: In most cases they are usually this, with a special mention to the teenage dragons.
  • Delinquents: The teenage dragons Spike has the misfortune to meet are mean-spirited enough to smash phoenix eggs for fun.
  • Dragon Hoard: The dragons keep hoards of jewels and other treasure, the implication being that these pull double duty as pantries, since dragons eat gems. The teenagers are shown to play a game of "King of the Hoard" when hanging out together.
  • Eat Dirt, Cheap: Dragons eat gemstones. This makes their treasure piles more like stored up rations.
  • Evil Albino: One of the teenage dragons has white scales and pink eyes.
  • Fantastic Racism:
    • They look down on ponies in general, particularly the importance they place on "friendship".
    • In the comics, they're on the receiving end of it. Spike learns that a number of dragons do live among ponies in Manehattan, but are subject to profiling and prejudice on account of the fact they're still dragons, even though they're perfectly nice unlike most other dragons.
  • Gem-Encrusted: Crackle the costume is covered in gems because Rarity designed it, but the real Crackle is also like this.
  • Gonk: You know Rarity's ugly, slap-dash dragon disguise? A real dragon looks like that and their name is Crackle.
  • Greed: It's their racial trait, and a part of their growing up. "Secret of My Excess" explains exactly why it is that both dragons encountered up to that point had massive hoards of valuables.
  • Jerkass: Most of the dragons fall under this, especially the teenage ones. "Basil" is indifferent to the harm it does and the teenage dragons are actively malicious.
  • Jerk with a Heart of Gold: "Basil" is at least willing to be peaceful and reasonable once Fluttershy scolds him.
  • Leitmotif: Straight-up rock for the teenage dragons.
  • No Name Given: The red and green dragons from "Dragonshy" and "Owl's Well that Ends Well".
  • Noble Demon: They may be dangerous and greedy, but the season six episode "Gauntlet of Fire" shows that, while they aren't fond of pony concepts such as friendship and companionship, they have a well-organized hierarchy and would prefer to leave the ponies alone even if they don't really understand their customs. When Ember becomes their new Dragonlord, she's more than willing to create bridges with ponykind and improve the relations between both species.
  • Non-Malicious Monster:
    • "Basil" is a threat mostly because his snoring is creating a huge cloud of smoke and he refuses to leave until Fluttershy scolds him (for the most part he doesn't even attack the Mane Six until he is provoked).
    • "Reginald", on the other hand, is a territorial Jerkass that tries to kill Spike for entering his cave and eating his gems.
    • Subverted with Garble, BIG TIME. Most dragons are apathetic at worst towards ponies, Garble actively hates them all and tries to murder a clutch of phoenix eggs for fun.
  • Ocular Gushers: When Fluttershy yells at him for roaring at her friends after Rainbow Dash kicked him in the face, "Basil" bursts into tears which resembles a rainstorm to the tiny ponies.
  • Our Dragons Are Different: Bizarre Alien Biology aside, most of the dragons' designs take after the classic European dragon as a basic template, including their characterization as powerful, ferocious monsters with a greedy behavior.
  • Palette Swap: The red and green adult dragons are palette swaps of one another that were used in order to save the animation team time.
  • Reptiles Are Abhorrent: Especially the teenage dragons. Garble in particular, who seems to be exceptionally malicious even by the standards of his own kind.
  • Rent-a-Zilla: The adult dragons are HUGE.
  • Shadow Archetype: The gang of teenage dragons is this to Spike. Unlike the kind, helpful Spike, they're a group of violent, bigoted thugs, showing what Spike might have become had he been raised among dragons.
  • Stock S Ound Effects: Pretty sure you've heard their roars on some other occasions.
  • Technicolor Fire: Dragons can breathe fire in many different colors.
  • Teens Are Monsters: The delinquent dragons from "Dragon Quest". The full-grown adult dragons only attack when provoked and greed-filled Spike, while destructive, more or less acts out of instinct and avoids lethal force when attacked. The delinquent dragons are full-on Jerkasses and love every minute of it, whether it's ridiculing baby dragons, their utter disrespect for ponies (even Princess Celestia), kidnapping phoenix chicks, or smashing phoenix eggs.
  • Vertebrate with Extra Limbs: Besides the standard four-legs-and-two-wings dragon body type, Crackle has four pairs of legs and one pair of wings.
  • Vile Villain, Saccharine Show: The adult dragons are very territorial, and the teenagers are disturbingly similar to real-life gangs of bullies.
  • Would Hit a Girl: They have no problem attempting to attack the ponies, even if they are female. In "Gauntlet of Fire", Garble has no problems attacking Princess Ember, despite her being both a girl and the current Dragon Lord's daughter.
  • Would Hurt a Child: They have no problem harming or threatening Spike, even if he is a baby dragon. The dragon from "Owl's Well That Ends Well" tries to eat Spike, which would be cannibalism. Garble and his gang take this Up to Eleven, being willing to slaughter a clutch of phoenix eggs for fun.

Behold the face of evil.

Adorable, spherical insect-like creatures with ravenous appetites that reproduce asexually. The parasprites came to Ponyville when Fluttershy brought one home as a pet, and soon bred out of control, forming a swarm that threatened to eat all the food in Ponyville.

  • Big Eater: The parasprite swarm almost ate all the food in Ponyvile.
  • Bizarre Alien Reproduction: The parasprites reproduce by throwing up, the resulting vomit becoming a new parasprite. Rarity appeared to be the only one who witnessed this firsthoof, much to her disgust.
  • Cute is Evil: Oh yeah. Zecora's description of them provides the page quote of this trope.
    ""Oh, monster of so little size... is that a parasprite before my eyes?"
  • Explosive Breeder: The parasprites reproduce by spitting out fully-formed babies, and can so very quickly when food is available—the ones in Twilight’s library went from a hoofful to a swarm of dozens thanks to one late-night snack.
  • Extreme Omnivore: The parasprites after Twilight cast her spell so they can't eat food. They almost eat Ponyville itself instead.
  • Horde of Alien Locusts: The parasprites, while not "aliens" in the sense of being extraterrestrial in origin, very much fit the other aspects.
  • I'm Taking Her Home with Me!: Most ponies' first reaction to seeing the adorable, seemingly harmless parasprites is to adopt them as pets and take them home. This proves to be a mistake.
  • Killer Rabbit: The parasprites are adorable little creatures, but when they swarm you'd better run for your life and keep any food and valuable belongings away from them.
  • Music Soothes the Savage Beast: Pinkie is able to distract the parapsrites from their feeding frenzy by means of a one-pony band, luring them out of Ponyville thanks to the creatures’ evident fondness for music.
  • Noisy Nature: They're small insectoid beings, yet they can utter squeals and coos.
  • Ridiculously Cute Critter: Very. The only one who wasn't taken in by their cuteness was Pinkie Pie, presumably because she had dealt with them before.
  • Zerg Rush: The parasprites do this during their feeding frenzy.


Winter spirits that feed off of hatred and cause deadly blizzards the more powerful they get. They existed before Equestria's founding and were seemingly destroyed when the three tribes united in friendship, triggering a powerful spell that vanquished them.

  • Always Chaotic Evil: Comes with the territory of being personified hate. In "A Hearth's Warming Tail", it's implied that they're the only beings in Equestria that are truly beyond any redemption.
  • Animalistic Abomination: They look like horses but they live in the atmosphere, feed off hatred, and generally appear otherwordly.
  • As Long as There is Evil: Or Conflict in their case. It's implied at the end of their debut that they will continue to exist as long as ponies are still able to feel hatred and anger, and if those conflicts reach the point that they were over a thousand years ago, the Windigoes will come back...
  • Big Bad: Of the Hearth's Warming Pageant and the founding of Equestria.
  • Character Overlap: In-universe. The Windigos appear as characters featured in both the "Hearth's Warming Eve" pageant and the A Hearth's Warming Tale story. Of course, it is strongly implied they are not mythical at all, which would make them an example of Historical-Domain Character for Equestria.
  • Darker and Edgier: Compared to a lot of antagonists in this show they are more serious, more frightening, and have nothing remotely redeeming about them. They do not speak, and in keeping with the wendigo myths their sole concern is to feed, never satisfied.
  • Diabolus ex Nihilo: Where they come from or what their plans are besides feeding off the ponies' hatred is never stated, but they do their plot-wise job of forcing the three races to stop fighting.
  • Emotion Eater: Feed off of hatred.
  • Eldritch Abomination: The closest things the series has to true Lovecraftian Horrors besides the Ursas, and indeed seem to be worse than them in this regard; they greatly resemble Ithaqua, a beast that came from the mind of H.P. Lovecraft himself. As a further comparison to such abominations, they are mysterious to the point that a number of ponies don't believe they exist, and are themselves seeming eternal and beyond any reasoning with by ponies. Destroying or imprisoning them for good seems impossible, they can only be repelled/banished and kept at bay.
  • The End... Or Is It?: They are seemingly incinerated by the friendship powered spell the union between the tribes causes. Although the end implies that they or more of their species are still out there.
  • Evil Is Deathly Cold: They are frost spirits that feed off hatred and almost created a frozen planet.
  • Family-Unfriendly Death: They seemingly burn to death. It's not that graphic, but it's still pretty unnerving. Albeit it seems more likely they were simply driven away.
  • Greater-Scope Villain: "A Hearth's Warming Tail" further confirms them to be this to Equestria as a whole. They are a seemingly eternal and implacable force that will destroy all life in Equestria should the ponies ever give them the opportunity to.
  • Harmless Freezing: Only in a sense. That is their ultimate freezing attempt on the Equestrian founders does not appear to be painful or necessarily fatal, their initial victims continuing to argue without even noticing it. However this may cross into A Fate Worse Than Death territory as their victims could be frozen, continuing to feel the hatred they felt at the time and thus continuing to feed the Windigos, unable to do or feel anything else.
  • An Ice Person: They can freeze entire countries.
  • It Can Think: They're strongly implied, mostly in the Hearth's Warming Pageant, to be sentient and capable of thought. Despite this, they cannot be reasoned with by ponies.
  • Kill It with Fire: It was friendship-powered fire, but they're destroyed or maybe repelled by fire nonetheless.
  • No Name Given: If they even have individual names.
  • Omnicidal Maniac: It's not made clear if they have a plan, but by the looks of it, the blizzards they create could render the world eternally frozen over at best and utterly lifeless at worst.
  • The Power of Hate: They feed off of hatred and use it to spread deadly blizzards everywhere they go.
  • Punny Name: Windigos cause blizzards.
  • Real After All: Their existence is heavily hinted to be more than an in-universe diary tale at the end of "Hearth's Warming Eve". In the in-universe story in "A Hearth's Warming Tail", Snowfall believes the Windigos are fables. She is very wrong.
  • Spell My Name with an "S": Word of God has used "windigos" but the closed captions use the "Wendigo" spelling.
  • Vile Villain, Saccharine Show: While when it comes to outright malevolence they're not on the level of Sombra or the Changelings, they're still freaking scary for this show. They turned the original pony homelands into a frozen waste in "Hearth's Warming Eve" and would have done the same to Equestria in the in-universe story in "A Hearth's Warming Tail"
  • Villainous Breakdown: It's subtle, but when the assistants begin reaching an agreement, one of the Windigos gives them a seemingly panicked Death Glare. When their affirmation strengthens, the Windigos roar with fury and try to make the blizzard stronger, encasing the assistants in ice even faster. This culminates in them screaming and flailing when the friendship fire drives them away.
  • Wendigo: Of the Ithaqua-esque variety.

Its bark is worse than its bite.

Creatures made of magically animated wood and branches from the trees of Everfree Forest, they have a wolf-like appearance. In Granny Smith's flashback in "Family Appreciation Day", the howl of the Timberwolves indicate the start of Zap Apple Season, while in "Spike at Your Service", they appear as generally dangerous creatures nopony should mess with.
  • Break Out Villain: Ever since their debut, they've been quite popular with fans of the show and have made constant reappereances since then.
  • Conspicuous CG: In their first appearance, the Timberwolves were animated like the other characters in Flash. In "Spike at Your Service", they are rendered using CGI, making them stand out from the rest of the Flash animation on the show, but then return to being animated in Flash when they combine to form a big Timberwolf.
  • The Dreaded: Ponies are terrified of these things.
  • Elemental Embodiment: The Timberwolves can form from ordinary sticks and branches; this further allows them to join together to form a single giant Timberwolf.
  • Glass Cannon: The fear Timberwolves invoke imply they can be deadly, but they can't take a hit — they shatter apart with a rock projected by Applejack, and even the giant Timberwolf suffers from choking and its dissipation after a small rock gets stuck in its throat. (They're all bark and no bite.)
  • Golem: They're made of wood but appear to be natural creatures instead of artificially made by someone.
  • Non-Malicious Monster: Despite how scary and creepy they are, Timberwolves just want to eat and survive.
  • Planimal: They are wolves made of trees.
  • Pulling Themselves Together: One of their tricks. They can even use it to combine into a single larger version.
  • Punny Name: They're timberwolves made of actual timber.
  • Savage Wolves: The Timberwolves are feared because of their vicious nature.
  • Super-Persistent Predator: The possible reason they are still very feared predators; they don't give up easily, and their regenerative abilities mean they'll be back to hunting even if they are destroyed.
  • Weaksauce Weakness: Choking to its demise on a small stone.
  • You Need a Breath Mint: One distinctive quality of Timberwolves is their rancid breath — Spike points this out as the flaw in the Mane Six's attempt to create a puppet of one.

    Vampire Fruit Bats
Debut: "Bats!"

Bigger, nastier relatives of Fruit Bats. The Vampire Fruit Bats suck fruit juices and spit out the seeds (which leads to the plants germinating).
  • '80s Hair: Some of them sport a furry, white mohawk on their heads.
  • Bat out of Hell: Of the Dire Bat variety — big as birds and ugly as sin.
  • Beauty Equals Goodness: Averted. Applejack wasn't lying when she said they were ugly, but that doesn't stop Fluttershy from wanting to defend them.
  • Dark is Not Evil: Downplayed. None of the Mane Six seem to see them as flat-out evil, but Applejack (somewhat rightfully) sees them as nuisances.
  • Nobody Poops: In real life, fruit bats disperse seeds by eating fruit, and passing the seeds through their droppings, far away from the parent tree. These bats on the other hand just suck the juices dry and spit the seeds out. Somehow this is helpful to the plants that sprout later on.
  • Non-Malicious Monster: They're big and scary-looking, but are not evil and can even be helpful. Fluttershy even lampshades this.
  • Planimal: Downplayed; they only have ears that look like leaves, but they're presumably close relatives to regular Fruit Bats, which are more obviously planimals.
  • Vegetarian Vampire: Unlike most vampires or real life vampire bats, they don't drink blood — they suck fruit dry of juice instead.

    The Smooze
Nothing can stop the Smooze from looking dapper!

The Smooze is a creature made of green slime. Consuming treasure and other shiny things makes it grow bigger. Its gunk is impervious to magic, but it likes calming music.

  • Adaptational Comic Relief: The G1 incarnation of the Smooze nearly causes a Sugar Apocalypse. The new one is more of a comedic nuisance.
  • Adaptation Dye-Job: Purple in the G1 movie, green at the gala.
  • Adaptational Heroism: Unlike the G1 movie, it isn't actively malicious and just can't help growing and spreading slime everywhere.
  • Adaptational Wimp: Subverted. Despite being a Non-Malicious Monster instead of a sapient cataclysm like its G1 self, it's still Nigh Invulnerable and has gained Anti-Magic abilities. It's just much more nice than the G1 version.
  • Anti-Magic: It's made of the stuff. A little slime on an alicorn's horn renders them powerless.
  • Big Eater: Absorbs things constantly.
  • Blob Monster: A sentient blob who likes eating shiny things.
  • Bow Ties Are Cool: The Smooze wears a red one to go with its top hat.
  • Cat Smile: It smiles this way after giving Discord an affectionate smooch.
  • Eat Dirt, Cheap: While it can technically engulf anything, it seems to prefer shiny jewels and metals.
  • Eldritch Abomination: A downplayed and relatively benign example, but the fact that neither Twilight nor Celestia's magic is capable of affecting it should probably be a tip-off that there's something particularly off about it.
  • It Can Think: At first it is not certain how sentient the Smooze is, but it kisses Discord after his apology.
  • "It" Is Dehumanizing: The Smooze is mostly referred to as "it" or a "thing", including by Discord, who isn't too convincing when he claims that he cares about his guest. The exception is Tree Hugger, who consistently uses male pronouns when talking about it.
  • The Juggernaut: The Smooze is both Nigh Invulnerable and Anti-Magic. Given its G1 self's reputation as this trope, this is rather fitting.
  • Miracle-Gro Monster: It grows in size with every object he eats.
  • Music Soothes the Savage Beast: It stops terrorizing the ballroom and covering everything in goop after listening to Tree Hugger sing.
  • Mythology Gag: Just like Tirek, the Smooze is inspired by the character of the same name from G1's My Little Pony: The Movie.
  • Nice Hat: The Smooze is particularly dashing in its top hat.
  • Nigh Invulnerable: Shares this with its G1 counterpart. It easily re-forms itself after being physically split in half by Discord, and Twilight's magic blasts do nothing to it.
  • Non-Malicious Monster: Although its appearance and habits suggest otherwise, it is actually a nice creature. It takes Discord's treatment in stride and enjoys the Gala once everything is settled.
  • No Sell: Magic blasts do nothing to the Smooze.
  • Not Evil, Just Misunderstood: It's a legitimately friendly creature, despite its spooky nature. Pinkie Pie adores it.
  • Odd Friendship: Does seem to have formed a genuine one with Discord. Any number of questions, including how they met, is left unaddressed.
  • Pulling Themselves Together. It gets squeezed in half by Discord at one point — and doesn't even seem to notice. Also, the slime it leaves behind seems to still be a part of the creature; when soothed by Tree Hugger's song, all of it oozes back into the Smooze, including the slime on the guests.
  • The Speechless: Makes no other sound than a belch during its screentime.
  • Sticky Situation: The Smooze's slime is (thankfully) not corrosive, but it is extremely adhesive. The slime sticks many ponies to the floor, leaving winged ones unable to fly — even Rainbow Dash, despite all her efforts.

    Other Various Monsters 
Along with the Ponies are various monsters. Most of them live in The Everfree Forest: an enigmatic place which is apparently free from the control of the rest of Equestria. Some of them are intelligent enough to be reasoned with while others are not. They have served as obstacles for the Ponies from time to time.

  • Adaptational Heroism: In the original Aboriginal myths it came from, the Bunyip is often described as a ferocious, malevolent, predatory beast with a taste for human flesh that lives on swamps, billabongs and creeks. Here, it is instead a friendly, sea-dwelling herbivore with a calm behavior.
  • All There in the Manual: According to its designer, Kora Kosicka, the yeti seen near Yakyakistan is named "Snowbutt McTwinkles".
  • All There in the Script: The toyline's Elements of Harmony Friends character collection set names the manticore Manny Roar.
  • Androcles' Lion: Manny Roar the manticore in "Friendship Is Magic – Part 2" is a straight-up homage to the fable.
  • Ascended Extra: Manny Roar the manticore from "Friendship is Magic – Part 2" will be getting a molded toy in the upcoming Elements of Harmony Friends character collection set.
  • Attack of the 50-Foot Whatever: The hydra, which is as big as a dragon.
  • Bears are Bad News: The Bugbear.
  • Bigfoot, Sasquatch and Yeti: On her way to Yakyakistan, Pinkie encounters a quadrupedal yeti living in a cave in the northern mountains, which is later referred to as pony-eating. Unlike the usual simian depictions, this one looks more like a bear/canine type of beast. May qualify as Fridge Brilliance if it's a nod to those skeptics who believe that sightings of sasquatches and similar creatures are misidentified sightings of bears rearing up on their hind legs.
  • Big, Friendly Dog: Surprisingly enough, Cerberus once Fluttershy calms him down. The smaller Orthros is this as well.
  • Cats Are Mean: There are two major feline-inspired monsters in the series. The lion-like manticores and the tiger-like chimeras. Manticores seem to have a friendly side and can get along with ponies, while chimeras, on the other hand, are ferocious predators willing to eat little fillies. (Albeit the book Princess Luna and the Winter Moon Festival has Luna peacefully reasoning with a chimera who didn't want to share its winter shelter with a manticore, leading to a fight between the two). Castle Sweet Castle from season 5 has a cover of a Daring Do book where she comes across a Sphinx, though those have yet to be seen in the flesh.
  • Canis Major: Cerberus is bigger than most buildings in Ponyvile.
  • Composite Character: The Bunyip's love for cucumbers may be a reference to the well-known Kappa of Japanese folklore.
  • Dark is Not Evil: Cerberus may look scary, but his job is to keep evil beings trapped in Tartarus.
  • The Dreaded: You know a cockatrice is bad news when it petrified Twilight Sparkle before it even shows up on screen; Fluttershy acts accordingly.
  • Eldritch Abomination: The Tatzlwurm is a downplayed version. It has a simplistic yet terrifying design, especially its mouth. Even Discord didn't know what it was, and it managed to make him sick.
  • Even Bad Men Love Their Mamas: The cockatrice was more than willing to leave the Cutie Mark Crusaders alone and revive its victims when Fluttershy threatened to tell its mom about its rude behavior.
  • Everything's Better with Dinosaurs:
  • Feathered Fiend: The cockatrice is part chicken, but given its status as The Dreaded, it's more in line with this trope than Clucking Funny.
  • Fearsome Critters of American Folklore: Jackalopes often appear as background fauna. They get along well with normal rabbits.
  • For the Evulz: We never find out why the Cockatrice turns people to stone. We can only assume that it's this.
  • Hellhound: Yes, even here! Cerberus appears as guardian of the Gates of Tartarus, while Orthrus is a kind of dog you can just up and buy, if you're up to training it.
  • Hoist by Their Own Petard: In her debut episode, the Chimera gets hit with this several times; first the snake head unwittingly trips the chimera when chasing Apple Bloom around the monster's legs, then the snake head gets lodged between two tree branches and the saber teeth of the tiger head get stuck in the trunk of another tree, leaving it completely immobilized.
  • Hero Antagonist: Cerberus briefly serves this role because he keeps the evil things in Tartarus locked away.
  • Hypnotic Eyes: The Chimera's snake head makes these briefly when plotting to eat Apple Bloom, though she never utilizes them.
  • Killer Rabbit: The Cockatrice is a silly-looking creature that's part chicken and part snake, but it turns anyone who looks it in the eye to stone. For fun.
  • Knight of Cerebus: Not to the extent of the Arc Villains, but some creatures such as cockatrices, timber wolves, and the chimera make episodes that were lighthearted before their appearance dip into horror movie territory.
  • Misplaced Retribution: Perhaps. A Big Lebowski allusion at the end of "Slice of Life" implies that the Bugbear killed Donny in the attempt to get to Bon Bon.
  • Mix-and-Match Critters: Many of them, including manticores, chimeras, and cockatrices.
    Scootaloo: The head of a chicken and the body of a snake? That doesn't sound scary, that sounds silly!
  • Multiple Head Case:
    • The hydra from "Feeling Pinkie Keen", whose heads clearly have minds of their own. And one of them is slower on the uptake.
    • The Chimera from "Somepony to Watch Over Me" has three heads working independently; a tiger, a goat, and a snake one. They refer to one another as sisters, and spend much of their time arguing with each other.
    • True to Greek myth, Cerberus has three heads, and the Orthrus in "Trade Ya!" has two.
  • Multipurpose Tongue: The Tatzlwurm has three long, prehensile ones.
  • Nature Is Not Nice: These creatures are dangerous, but for the most part are only hungry or territorial, not actively evil.
  • Never Smile at a Crocodile:
    • One of the creatures that live in the Everfree Forest is a cragadile, a giant crocodile made out of rock that tries to eat the main characters when they try to cross the pond it lives in.
    • The Cipactli, a gigantic pony-eating crocodile serving as an ancient temple's guardian monster.
    • Rainbow Dash and the Daring Do Double Dare introduces Colossa-Gators, gigantic alligators about the size of an Ursa Minor with red-eyes and iridescent scales.
  • Noisy Nature: Oh yeah. Whenever they chase their prey, the monsters constantly keep roaring, growling, snarling and making all types of sounds. Might be justified by the fact these are, well, mythical monsters we're talking about. Special mention goes to the Hydra, which rises ominously from the swamp and lets out a thunderous roar once it corners the ponies in Feeling Pinkie Keen. Heck, one of its heads even gets a little delayed and roars with the others when it notices them.
  • No Name Given: With the exception of Cerberus, Manny Roar and Snowbutt McTwinkles. Even the parasprites who are briefly taken in as pets don't get named.
  • Non-Malicious Monster: Cerberus is big and scary and can cause a lot of damage, but he's a guard dog who ran off from his guard post.
  • Our Manticores Are Spinier: Large, lion-like animals with bat wings and scorpion tails. Some have horns. Generally seem to take the narrative roles lions get elsewhere.
  • Our Monsters Are Different: Most of the creatures are taken directly from real-life mythology, but they have their own flavor to them.
  • Our Monsters Are Weird: Oh yeah, from wolves made of wood, crocodiles made of stone, yetis that look like bears, and several downright bizarre beasties, the legendary menagerie of Equestria is truly unique, to say the least. And don't get us started on the things which live on Discord's dimension and in the Scariest Cave in Equestria...
  • Palate Propping: In "Rock Solid Friendship", Pinkie has to use a jack to force open a quarray eel's jaws so that she can retrieve Maud from the creature's mouth.
  • Planimal: The Fruit Bats, bats made of fruit.
  • Punny Name: Manny Roar the manticore.
  • Red Eyes, Take Warning: The cockatrice sports them.
  • Rent-a-Zilla: Many of the monsters are huge beasts.
  • Sand Worm: The Tatzlwurm, which burrows through stone and soil with speed and ease.
  • Sea Monster: Sea serpents like Steve Magnet are sapient and friendly. "Gauntlet of Fire" features another kind of sea serpent which ressembles an abyssal fish.
  • Shock and Awe: The (possibly real, possibly not) twittermites, insects that create localized lighting storms when they swarm.
  • Slippery as an Eel: The quarray eels, which are apparently a huge, predatory species of land-dwelling fish. Like true morays, they make their home on the caves in the rocky crevices of Ghastly Gorge and hunt down whatever passes near their lair.
  • Sssssnake Talk: The Chimera's snake head speaks this way.
  • Stock Sound Effects: Most of their roars are generic sounds made by the one and only Frank Welker.
  • Taken for Granite: The cockatrice has the ability to inflict this.
  • Toothy Bird: The cockatrice, although it isn't really a bird.
  • Vocal Dissonance: While all three heads of the Chimera are sisters, the tiger head's voice is much deeper and more masculine than the others.
  • Your Size May Vary: Manny Roar the manticore's molded toy from the upcoming Elements of Harmony Friends character collection set is on a smaller scale than the ponies' equivalent molded toys.
  • Yowies and Bunyips and Drop Bears, Oh My: Tri-horned bunyips, large and vaguely doglike sea monsters with three horns in a row down their snout and fondness for cucumber. Interestingly enough, bunyips in Australian folklore are freshwater dwellers and carnivores, unlike the show's saltwater herbivores.
