* MagicKnight: Reigar are no slouches in close combat, and also accomplished mages/psions. Their ''AD&D'' material notes that while they have access to all schools of magic, they dismiss illusions as gauche, since they dislike making things that aren't real.
* ParodySue: They're near-immortal, inhumanly beautiful, superbly fashionable, and even sparkle. They're {{Shrouded in Myth}}s along the lines of "the reigar taught the elves everything they know about art, and the elves forgot most of it," are rumored to give orders to the mercanes or even mind flayers, and are variously credited with creating races from the zodar to humanity, as well as the first ''spelljammer helm''. They have access to special organic spaceships and magical animal-themed armor unlike anything used by other races, made of a special material harder than steel. And so on.
* PowerUpMount[=/=]PoweredArmor: ''Shakti'' are palm-sized animal statuettes similar to a ''figurine of wonderous power'' (which the reigar are credited with inventing) normally worn or carried by a reigar. But with one command word, the statuette grows to eight feet long, becoming a flying vehicle the reigar can sit or [[SkySurfing stand on.]] Another command word transforms the ''shakti'' into a suit of armor and accompanying weapon, themed to the animal statuette it started as, with a special ability such as a fiery blast for a dragon-themed ''shakti''.

* BloodyMurder: They can spray thick gouts of blood from the symbols carved into their faces, which can cause all those hit with the stuff to [[SetAMookToKillAMook perceive their allies as enemies and spend several rounds trying to murder them.]]
* LivingStatue: A dark deity that was especially pleased with a particular cult cell sometimes sent the tiniest shred of its power infuse that cult's statue, granting it minimal sentience.
* MurderousMalfunctioningMachine: A fantastic example. Over the years, most of these constructs went insane from the dark energies within them, becoming rogue eidolons that in many cases murdered the very cults they were created to protect. Now they act at random, sometimes ignoring an adventuring party entirely, perhaps mistaking it for a group of cultists, and other times attacking the same adventurers they ignored previously.
* StupidityInducingAttack: Those hit by a rogue eidolon's slam attacks have to save or become permanently ''confused'', acting randomly until healed by magic like ''greater restoration'' or ''limited wish''.

Gigantic, arctic-dwelling centipedes whose bodies give off tremendous amounts of heat.

* ArchEnemy: Remorhazes and frost worms attack each other on sight, resulting in terrible battles that can devastate entire areas. The remorhazes usually win such brawls due to [[ElementalRockPaperScissors damage typing]] -- their bites and bodies inflict fire damage, which [[WeakToFire frost worms are vulnerable to]], but remorhazes don't actually have the fire subtype, meaning the frost worms don't get any damage multipliers against them.
* BeastOfBattle: Remorhazes can be trained from hatchings to obey commands and guard frost giants' citadels.
* CreepyCentipedes: They resemble monstrous centipedes, are big enough to prey upon polar bears and mammoths, and can swallow a human whole. They can give an adventuring party a serious fight as a result.
* DigAttack: Remorhazes have a respectable burrowing speed, which they use to burst out of the ice and snow and ambush prey.

* EyeBeams: Retrievers have multiple eyes that can make different magical attacks. In 3rd Edition, they can shoot beams of fire, cold or electricity, or a ray of [[TakenForGranite petrification]], but they can only make one such attack per round, and each ray can only be used once every four rounds. 5th Edition streamlines things so that retrievers can either fire a beam that deals [[NonElemental force damage]] or another that [[TheParalyzer paralyzes the target]].

* {{Acrofatic}}: Rheks are seven feet tall and weigh 350 pounds, but can still employ the monk class' acrobatics and increased movement.
* BareFistedMonk: Rhek chaosgrinders are skilled martial artists who don't require weapons to destroy their enemies.
* HealingFactor: Downplayed; they don't have fast healing or regeneration, but their redundant internal organs and rapidly-congealing blood mean that rheks automatically stabilize themselves when brought below 0 hit points.
* HolyHandGrenade: All rheks can make a ''Smite Chaos'' attack three times per day, dealing extra damage to Chaotic foes.
* HornAttack: They can make gore attacks with their horns, which does double damage during a charge.
* RhinoRampage: They're anthropomorphic rhinos, and while not bloodthirsty, are perfectly willing to enforce their vision of order through violence.
* SuperOCD: Fittingly for the more-Lawful-than-Good plane of Arcadia, rheks lean into this, striving for harmony and perfection by making sure everything is in its proper place, and having little tolerance for unpredictability.

* AttackAnimal: Rust monsters can be domesticated, most commonly by gnomes, to serve as guard beasts, making up a first line of defense that disarms intruders for other guards to mop up. But the creatures' lust for rust overrides any training or loyalty to their masters, so their handlers shouldn't keep any metal on them during interactions.

* BlowYouAway: Raptorans gained their power of flight from an ancient pact with the lords of the Elemental Plane of Air, which also lets raptoran mages cast spells with the air descriptor at a higher level than normal.
* DeathFromAbove: An airborn raptoran can make a dive attack to deal double damage with a piercing weapon.
* DivorceIsTemporary: Along with marriages; raptorans marry in the spring, and each marriage lasts for a matter of months, long enough for a couple to produce eggs (if both partners are fertile) and raise their hatchlings to fledglings. The next year, a raptoran couple may renew their previous marriage to one another, or wed different partners for the season.

* ImmortalProcreationClause: Raptorans live longer than humans but shorter than elves or dwarves, and have cyclical periods of fertility between the ages of 20 and 150, during which time a given raptoran (male or female) will only be fertile for one year out of three.

* BigEater: Rasts are insatiable creatures that eat almost continuously.
* {{Flight}}: They have the supernatural ability to fly, though if this power is suppressed, rasts are nearly helpless on the ground despite their many legs. In such cases they can only make a single move or attack action each round, and move at most five feet.
* ImmuneToFire: As creatures with the Fire subtype, rasts are immune to such damage, [[AchillesHeel but take extra damage from cold.]]
* MonstrousCannibalism: Packs of rasts will never eat their own, but will happily attack and feast on rival packs.
* MultiArmedAndDangerous: Rasts can have up to 15 claws, but can only use up to four at once.
* TheParalyzer: A rast's mere stare can paralyze opponents for several rounds, leaving it free to focus its attacks on those who resisted its gaze.

'''Alignment:''' ChaoticGood

Humanoids resembling flying squirrels, who live upon, worship and protect the plane-spanning world tree Yggdrasil.

* BeastMan: They're Medium-sized squirrel-folk, specifically flying squirrels, and as such can glide with their flaps of skin and have larged, flattened tails they use to steer while in the air.
* BerserkButton: They take their self-appointed role as Yggdrasil's guardians very seriously, and will fight to the death to defend her. Similarly, don't question their CreationMyth that insists that the ratatosk were hatched from a nut on the top of the tree, making them the favored creations of Yggdrasil. Finally, they take a dim view of interlopers starting fires while traversing the world tree, who might wake to find their mounts loose, their food scattered, and their tents collapsing around them.
* DodgeTheBullet: The ratatosk are skilled at dodging missile attacks on the wing, and in 2nd Edition can roll to negate even magical attacks like ''Melf's acid arrow''.
* HitAndRunTactics: When forced to fight, ratatosk prefer to [[DeathFromAbove dive down on foes from above]], then disengage and scamper up a branch to repeat the process.
* IShallTauntYou: They have a supernatural ability to infuriate sentient creatures with their words and mocking tone, which can cause those affected to throw aside ranged weapons or spell components as they try to chase down and attack the offending ratatosk in melee combat.
* AKindOfOne: Ratatoskr was an individual squirrel in Myth/NorseMythology, who runs up and down Yggdrasil's trunk, bearing messages between the serpent Níðhöggr at its roots and the eagle atop its crown. Here the ratatosk are an entire race that serves a similar role.
* ScrewballSquirrel: Ratatosk packs might harass and taunt any creatures they deem intruders within Yggdrasil's boughs, steal metal goods from passersby, and if pressed into combat do so out of panic rather than bloodlust, even when defending their young. But if sufficiently bribed (usually with one of Yggdrasil's huge, sterile seed pods), they can be willing to carry messages to anywhere the great tree reaches.

Strange flying serpents native to the Positive Energy Plane, and as such brim with life energy. They consider the rest of the cosmos a comparatively desolate place, and on other planes will use their abilities to animate everything around them.

* AchillesHeel: According to their ''Planescape'' stats, ravids are instantly slain by an ''energy drain'' spell or the touch of a life-draining undead like a wraith or spectre, though in the latter case the result is also a MutualKill. For this reason, ravids are terrified of the undead.
* AnimateInanimateObject: Ravids can use the ''animate objects'' spell as a 20th-level caster, at will. As a result, they're usually surrounded by animated objects that will defend the ravid to the best of their ability (though the ravid isn't smart enough to use tactics when directing its minions), and a ravid's progress through an area can be tracked by the unnaturally lively environment.
* ExplosiveOverclocking: Their ''AD&D'' rules are a bit more involved about the consequences of a character getting dosed with a ravid's positive energy, ranging from having the character's hit point total ''decrease'' if the touch "overhealed" them, to a ''haste'' effect that also [[RapidAging ages the subject one or two years from the burnout]], to granting the benefits of a ''strength'' spell at the cost of permanently reducing the subject's Strength afterward, again from the physical burnout.
* HealingShiv: Ravids' tail slaps and singular claw attacks lash a target with positive energy. In the case of living creatures, this can heal whatever physical damage the ravid's attack dealt, while [[ReviveKillsZombie undead will instead take extra damage from the positive energy.]]

A plant resembling organic razorwire, found all across the Lower Planes, parts of the Outlands, and even within the planar metropolis of Sigil.

* AlienKudzu: The stuff can grow just about ''anywhere'', at a rate of several feet per day, so that a single plant can expand to cover a building or untended wall in just a week, and just a single cutting can quickly grow into a full-fledged tangle. It probably originated somewhere in the Abyss, but can now be found on multiple planes. Razorvine is such a pain to get rid of that it's rumored that the planar border town of Ribcage had someone drawn and quartered after re-introducing the plant right after their latest clearing effort. Still, some people cultivate it as a passive defense against thieves and other intruders.
* AlienLunch: Only two animals are known to be able to eat razorvine, the boar-like fhorges, and quills, armored porcupines.
* CounterAttack: The plant's twisting vines are under tension, so each time someone trys to cut at it, they're lashed by a strand springing free of the main mass.
* CraftedFromAnimals: Well, plants, but it's possible to treat razorvine cuttings to preserve their sharpness and flexibility, for use as [[WhipSword bladed whips]], bindings that cut any prisoner that tries to wriggle out of them, or cruel garrotes.
* ImmuneToFire: Downplayed; living razorvine only hardens when exposed to conventional fire, but magical flames deal full damage, and once cut and dried it makes for decent kindling.
* MainliningTheMonster: A pair of elven brothers in the Outlands border town of Curst knows the trick of turning razorvine leaves into heartwine.
* RazorFloss: Anyone unfortunate enough to fall into a patch of razorvine takes damage from the initial drop, and then additional damage each round they try to extricate themself.

Amorphous subterranean horrors that must murder other creatures in a desperate attempt to maintain their sentience.

* BlobMonster: In its nonsentient, default form, a reason stealer is a 4-foot-wide puddle of grainy, brown-yellow slime.
* CannibalismSuperpower: After dealing the killing blow to a creature, a reason stealer transfers its victim's Intelligence score to itself, which both heals it and allows the ooze to use its victim's ability scores, skills, feats, prepared arcane spells, saving throws, and attack bonuses. The ooze also changes form, reshaping its body into a grotesque parody of its latest victim, allowing it to use weapons and items. If the reason stealer kills another creature after that, the mental benefits are cumulative in the case of spells or feats, or it uses the better of the two attributes in the case of ability scores, skill ranks, and so forth. But in any case, these benefits only last for 24 hours, at which point the reason stealer collapses back into a mindless blob.
* SuperSenses: Reason stealers are blind, but their entire bodies are primitive sensory organs able to track prey by vibration and scent, giving them blindsight out to 60 feet.
* TalkativeLoon: After stealing a creature's mind, the monster mumbles random words in its victim's language.

* AcidAttack: Red sundews are coated in acidic gunk that [[DamageOverTime damage for several rounds after exposure]], unless washed off with a gallon of water as a full-round action.
* InformedSpecies: They're called sundews, but are described as "a wide mound of tangled, ropy rags in red, green and rust colors," which is pretty different from what real-world plants from the ''[[https://en.wikipedia.org/wiki/Drosera Drosera]]'' genus look like.
* ManEatingPlant: They're aggressive hunters capable of moving 20 feet each round, and they're much more nomadic than other plant monsters, wandering from hot jungles and coastal forests to cooler woodlands in search of prey.
* NoSell: They're immune to both fire and acid.
* SupernaturalSensitivity: Like their greenvise cousins, red sundews can detect anything within 60 feet that's in contact with some form of vegetation.

Some redcaps seek out and kill whoever shed blood to create them, others work with a murderous creator as kindred spirits.
* OrganDrops: Redcaps vanish when they die, leaving behind a single tooth that, when worn, grants the wearer a minor bonus on Charisma checks when dealing with fey, particularly other redcaps.
* PintSizedPowerhouse: Though Small creatures that look like hunched, wizened old humanoids, redcaps are quite strong for their size, able to wield Medium-sized weapons without difficulty and grapple larger opponents on equal terms.

* LongNeck: 20 feet long, to be precise, enough that a rokuro-kubi can use it to [[TentacleRope wrap around and constrict opponents]] -- though they'll obviously reserve that attack for isolated victims.
* SnakePeople: They're compared to hannya and hebi-no-onna as another monstrous humanoid with serpentine features, and speak both Common and Yuan-Ti.

'''Alignment:''' ChaoticEvil

Loathsome beings from the Elemental Plane of Earth who delight in deceiving and ruining the lives of mortals.

* AcidAttack: Their bite attacks are physically weak, but also hit victims with more serious acid damage.
* {{Cult}}: Rukarazylls usually operate by assuming charismatic humanoid guises and setting up cults supposedly dedicated to a benevolent, but wholly fictitious, minor deity. Over time, they pervert their cult's worship to that of an existant, evil deity.
* EldritchAbomination: Rukarazylls' central bodies are masses of fungoid matter studded with eyes, with six barbed tendrils that can serve as legs or hands as needed, as well as a horned, skull-like head on a stalk, with fungal filaments growing from its empty eye sockets and acidic black goo bubbling from its fanged mouth.
* FesteringFungus: Any creature hit by a rukarazyll's melee attack has to save or become infested with a fungus. A few rounds later, fibrous white filaments grow out of the victim's body, actively interfering with their movements to impose a penalty on attack rolls and Dexterity-based checks. Worse, the fungus' secondary effect deals [[NonHealthDamage Charisma drain]] each day, and when a victim's Charisma reaches zero, they fall unconscious and soon transform into a heap of fungoid matter that can infect new victims. Thankfully, a ''remove disease'' spell -- or taking 10 points of fire or cold damage -- removes the infestation.
* HonestJohnsDealership: When they aren't running cults, rukarazylls amuse themselves by selling cursed magic items they pass off as beneficial.
* MookMaker: Once every ten minutes, a rukarazyll can spit up a gray ooze that fights alongside it for up to eight rounds before dissolving into goo.
* {{Plaguemaster}}: They can cast magic like ''unholy blight'' and ''contagion'', and rukarazylls are known to try to pass themselves off as healers, only to inflict diseases upon those seeking aid.
* VoluntaryShapeshifting: Beyond using ''alter self'' at will, rukarazylls can use ''polymorph self'' three times per day to aid in their infiltration of Material Plane society.

* AnimalisticAbomination: They're aberrant canids, with a freakishly large, eyeless head on a long neck attached at the middle of their spine rather than the front of their bodies, and strange glyphs and tattoos inscribed upon their hairless flesh.
* LongNeck: Runehounds' are long enough to give them a 10-foot reach with their bite attacks despite being Medium-sized monsters, but said necks are also flexible enough to let them attack adjacent foes without penalty.
* StickySituation: Instead of acid, runehounds can spit a glob of sticky goo that acts a single-target ''web'' spell.
* SupernaturalSensitivity: Runehounds are eyeless, but can track non-mindless creatures by their "psychic scent," though this can be foiled by magic or psionics that grant [[PsychicBlockDefense shields against mental effects.]] The creatures also use their psychic abilities to perceive their surroundings, and have blindsight out to an uncanny 500 feet.

Beautiful female spirits bound to cold rivers, lakes and streams, known to use their beguiling songs to lure in men for companionship, or to simply drown them.

* CantLiveWithoutYou: Like similar fey, a rusalka will perish if taken too far from her home waters, beginning to drown until she's immersed in them.
* CompellingVoice: A rusalka's song forces a single creature within 300 feet to save or become compelled to move toward her, taking the most direct route possible. Those who follow her into deep enough water are in danger of drowning, but any who come within 5 feet of the rusalka become ''[[CharmPerson charmed]]'' by her.
* OurNymphsAreDifferent: They're bound to a body of freshwater much like dryads are bound to trees.
* StarCrossedLovers: Some lonely rusalkas will entice men to join them in their streams or ponds, using their magic to let their paramours stay with them safely beneath the surface. Such relationships always end sadly, as the rusalka realizes her lover is not truly content in her world, and eventually frees him from her enchantments and stops casting ''water breathing'' on him, to force him back onto land.
* SuperNotDrowningSkills: They can cast ''water breathing'' four times per day, if a rusalka desires a companion rather than a drowning victim.
* UglyGuyHotWife: Rusalkas are sometimes depicted as the wives of the filthy, pot-bellied vodyanoi, their fellow water fey.

Over the years, most of these constructs went insane from the dark energies within them, becoming rogue eidolons that in many cases murdered the very cults they were created to protect.

* BerserkButton: For some unexplained reason, manufactured items, especially those made of metal, drive rampagers completely mad. They'll prioritize attacking armored foes over any other, then those wielding metal weapons, followed by structures, and will ignore other foes attacking with non-metal weapons while doing so, at least until the rampager loses half its hit points.
* BloodKnight: Rampagers enjoy killing, and usually kill far more than they can eat. As long as prey is available, a rampager doesn't even stop killing long enough to feed.
* {{Cephalothorax}}: Their upper torsos don't have heads, just eyes and a mouth in the middle of their "chest."
* HeavySleeper: Rampagers tend to sleep through the heat of the day, and some bold adventurers have been known to walk right over the creatures without waking them.

* {{Flight}}: They have the supernatural ability to fly, though if this power is suppressed, rasts are nearly helpless on the ground despite their many legs. In such cases they can only make a single move or attack action each round, and move at most five feet.

* BerserkButton: They take their self-appointed role as Yggdrasil's guardians very seriously, and will fight to the death to defend her. Similarly, don't question their CreationMyth that insists that the ratatosk were hatched from a nut on the top of the tree, making them the favored creations of Yggdrasil. Finally, they take a dim view of interlopers starting fires while traversing the world tree, who might wake to find their mounts loose, their food scattered, and their tents collapsing around them.
* DodgeTheBullet: The ratatosk are skilled at dodging missile attacks on the wing, and in 2nd Edition can roll to negate even magical attacks like ''Melf's acid arrow''.
* HitAndRunTactics: When forced to fight, ratatosk prefer to [[DeathFromAbove dive down on foes from above]], then disengage and scamper up a branch to repeat the process.
* IShallTauntYou: They have a supernatural ability to infuriate sentient creatures with their words and mocking tone, which can cause those affected to throw aside ranged weapons or spell components as they try to chase down and attack the offending ratatosk in melee combat.
* AKindOfOne: Ratatoskr was an individual squirrel in Myth/NorseMythology, who runs up and down Yggdrasil's trunk, bearing messages between the serpent Níðhöggr at its roots and the eagle atop its crown. Here the ratatosk are an entire race that serves a similar role.
* ScrewballSquirrel: Ratatosk packs might harass and taunt any creatures they deem intruders within Yggdrasil's boughs, steal metal goods from passersby, and if pressed into combat do so out of panic rather than bloodlust, even when defending their young.

Strange flying serpents native to the Positive Energy Plane, and as such brim with life energy. They consider the rest of the cosmos a comparatively desolate place, and on other planes will use their abilities to animate everything around them.

* AchillesHeel: According to their ''Planescape'' stats, ravids are instantly slain by an ''energy drain'' spell or the touch of a life-draining undead like a wraith or spectre, though in the latter case the result is also a MutualKill. For this reason, ravids are terrified of the undead.
* AnimateInanimateObject: Ravids can use the ''animate objects'' spell as a 20th-level caster, at will. As a result, they're usually surrounded by animated objects that will defend the ravid to the best of their ability (though the ravid isn't smart enough to use tactics when directing its minions), and a ravid's progress through an area can be tracked by the unnaturally lively environment.
* ExplosiveOverclocking: Their ''AD&D'' rules are a bit more involved about the consequences of a character getting dosed with a ravid's positive energy, ranging from having the character's hit point total ''decrease'' if the touch "overhealed" them, to a ''haste'' effect that also [[RapidAging ages the subject one or two years from the burnout]], to granting the benefits of a ''strength'' spell at the cost of permanently reducing the subject's Strength afterward, again from the physical burnout.

It probably originated somewhere in the Abyss, but can now be found on multiple planes. Razorvine is such a pain to get rid of that it's rumored that the planar border town of Ribcage had someone drawn and quartered after re-introducing the plant right after their latest clearing effort. Still, some people cultivate it as a passive defense against thieves and other intruders.
* AlienLunch: Only two animals are known to be able to eat razorvine, the boar-like fhorges, and quills, armored porcupines.
* CounterAttack: The plant's twisting vines are under tension, so each time someone trys to cut at it, they're lashed by a strand springing free of the main mass.
* CraftedFromAnimals: Well, plants, but it's possible to treat razorvine cuttings to preserve their sharpness and flexibility, for use as [[WhipSword bladed whips]], bindings that cut any prisoner that tries to wriggle out of them, or cruel garrotes.
* ImmuneToFire: Downplayed; living razorvine only hardens when exposed to conventional fire, but magical flames deal full damage, and once cut and dried it makes for decent kindling.
* MainliningTheMonster: A pair of elven brothers in the Outlands border town of Curst knows the trick of turning razorvine leaves into heartwine.

* CannibalismSuperpower: After dealing the killing blow to a creature, a reason stealer transfers its victim's Intelligence score to itself, which both heals it and allows the ooze to use its victim's ability scores, skills, feats, prepared arcane spells, saving throws, and attack bonuses. The ooze also changes form, reshaping its body into a grotesque parody of its latest victim, allowing it to use weapons and items. If the reason stealer kills another creature after that, the mental benefits are cumulative in the case of spells or feats, or it uses the better of the two attributes in the case of ability scores, skill ranks, and so forth.

Strange flying serpents native to the Positive Energy Plane, and as such brim with life energy. They consider the rest of the cosmos a comparatively desolate place, and on other planes will use their abilities to animate everything around them.

* AchillesHeel: According to their ''Planescape'' stats, ravids are instantly slain by an ''energy drain'' spell or the touch of a life-draining undead like a wraith or spectre, though in the latter case the result is also a MutualKill. For this reason, ravids are terrified of the undead.

As a result, they're usually surrounded by animated objects that will defend the ravid to the best of their ability (though the ravid isn't smart enough to use tactics when directing its minions), and a ravid's progress through an area can be tracked by the unnaturally lively environment.
* ExplosiveOverclocking: Their ''AD&D'' rules are a bit more involved about the consequences of a character getting dosed with a ravid's positive energy, ranging from having the character's hit point total ''decrease'' if the touch "overhealed" them, to a ''haste'' effect that also [[RapidAging ages the subject one or two years from the burnout]], to granting the benefits of a ''strength'' spell at the cost of permanently reducing the subject's Strength afterward, again from the physical burnout.

** Rocs have appeared since the game's first edition as birds of prey large enough to carry off elephants in their claws. They are often associated with [[OurGiantsAreBigger giants]], who tame them as aerial mounts, although wild rocs will hunt giants.

** In ''TabletopGame/AlQadim'', it should come as no surprise that they are a prominent part of the setting, given the ArabianNightsDays theme. In fact, the setting has ''three'' variations. Asides from the common roc found in other settings, there are also the intelligent great rocs and the evil-aligned two-headed rocs (based on the Creator/RayHarryhausen one from ''Film/The7thVoyageOfSinbad'').

* FoodAsBribe: They're actually easily tameable and friendly creatures if given scrap metal snacks.
* HorseOfADifferentColor: Some dwarves are known to breed Large rust monsters to be ridden into battle by soldiers wielding stone weapons and wearing hide or stone armor. Such cavalry can rout an enemy army all on its own.
* MetalMuncher: Rust monsters subsist on rust, which they can create by touching any kind of metal. Their cousins, the folugubs, can liquefy crystals at a touch and feed on the result. They corrode metal extremely quickly, enough so that corroding and consuming enemy weapons mid-combat is a very viable combat tactic for them.
* MooksAteMyEquipment: Rust monsters are the bane of any player who wears metal armor or carries metal weapons, as the touch of a rust monster's antennae corrodes metal in the blink of an eye.
* PaintingTheMedium: The rust monster's illustration in the first edition's ''Monster Manual'' shows its corrosive antennae eating a hole in the picture's frame.
* {{Retcon}}: ''TabletopGame/{{Planescape}}'' posits that rust monsters are the larval forms of the much more dangerous rust ''[[Characters/DungeonsAndDragonsDragons dragons]]'' of Acheron. This has been ignored by later entries for rust dragons.
