Droch
Homeworld: Unknown; first discovered on Nam Chorios
Debut: Planet of Twilight
Parasitic insects that are vulnerable to direct sunlight.
- Life Drain: Drochs feed by burrowing under larger creatures' skin to drain life energy from them. Older and more matured drochs can do this by proxy using their lesser kin.
- Metamorphosis Monster: Drochs start off as little beetles that burrow into people and are supposedly quickly killed by the immune system. That's dependent on light, though; in the dark, they grow into horribly fat, claw-legged and Lamprey Mouthed monstrosities that use their little siblings to drain pure Life Energy from a distance, but they'll attack directly to gain biomass. One or two can become something like a protoshoggoth, with a normal human head atop a maw-studded body.
- Monster Lord: Most drochs are mindless insects. If they consume a particularly large amount of energy from their victims, however, they can grow in size and intelligence until they become large, monstrous "captain drochs", which can then use their smaller siblings as proxies to feed on more victims and become steadily larger and more intelligent.
- Weakened by the Light: Daylight kills drochs. On Nam Chorious, the natural crystalline landscape reflects it around so as to keep them very effectively contained. In space, far from natural light, they can quickly breed to plague proportions.
Energy Spider
Homeworld: Kessel
Debut: Jedi Search
Giant, energy-eating arachnids that live in the cave systems of Kessel. Unknown to most of the galaxy, they're the only source of glitterstim, the most prized variant of spice, which is in fact their photosensitive webbing.
- Atrocious Arthropods: In appearance and disposition, energy spiders resemble something from the depths of an arachnophobe's nightmares far more than any real animal. They're ravenous, predatory beasts, their bulbous bodies covered in dozens of milky eyes and bristling with long, spear-like legs.
- Extra Eyes: Energy spiders exceed even regular arthropods in this department, as their entire anterior bodies are covered in dozens of milky eyes.
- Fantastic Diet Requirement: They feed on energy. By preference they prey on a type of non-sapient Energy Beings that share their homeworld, but they're equally happy draining the heat and life from organic lifeforms or absorbing blaster bolts.
- Giant Spider: They resemble monstrous spider-like arthropods big enough to prey on humans.
- Monster Organ Trafficking: There have been a number of attempts at farming these things to establish reliable production of glitterstim, although most have failed due to a combination of the spiders' finicky habitat and diet preferences and their high aggressiveness.
- Nothing Is Scarier: When one is first encountered in Jedi Search, it's in the pitch blackness of the deep mines. The characters are only aware that there's something big in the darkness with them, something fast and dangerous that's picking them off one by one, but cannot even begin to guess what it is until Han, who has secured a set of infrared goggles, gets a quick glimpse — and even then, all he sees are the silhouetted shapes of several long, slender legs around the warm body of the creature's victim.
- Vampiric Draining: Energy spiders are entirely happy to feed on the energy of other living creatures, a process that leaves their victims frozen and dead.
Gizka
Homeworld: Unknown
Debut: Knights of the Old Republic
Bipedal, froglike pests that often infest spaceships and space stations.
- Armless Biped: Gizkas possess a pair of long, froglike legs, and no other limbs.
- Explosive Breeder: Gizkas are infamous for their extremely fast reproductive rate, which is one of the primary reasons for their status as vermin. In-game, this is given as the reason why just going around killing them won't rid the Ebon Hawk of them — they just recover their losses too fast.
- Fantastic Vermin: They're widespread and pernicious pest animals, due to an unfortunate combination of tolerating almost any environment, breeding so fast that they put rabbits to shame, and a tendency to eat electric wiring.
- Shout-Out: They're inspired by the tribbles from the Star Trek: The Original Series episode "The Trouble with Tribbles", another type of extremely fast-breeding pests that infest starships. This extends to the name of the in-game quest where you need to get rid of them, "The Trouble with Gizka".
- Tastes Like Chicken: According to Trandoshans, gizkas are one of those foods that everything tastes like, and they often describe other meats as tasting like gizka.
Gundark
Homeworld: Vanqor
Debut: The Empire Strikes Back (first mentioned)
"You look strong enough to pull the ears off a gundark."
—Han Solo
Six-limbed predators that live in communal warrens, gundarks are infamous for their aggressive dispositions. In addition to the true gundarks of Vanqor, the word is also used to refer to a variety of dangerous and ill-tempered animals from across the galaxy.
- Bizarre Alien Locomotion: Their legs are nothing more than a pair of sharp claws, and they instead mostly move using their muscular forearms.
- Early-Installment Weirdness: The first visual depiction of gundarks in the franchise is in issue 51 of Star Wars (Marvel 1977). However, these don't resemble the later gun dark depictions in any way, being instead orange, hammer-headed, long-necked beings who use long, sticky tongues to catch their prey. This was later addressed when Legends canon established that there are multiple animal species called "gundarks" due to their rotten dispositions.
- Hold Your Hippogriffs: Telling someone that they're "strong enough to pull the ears off a Gundark" means that they're quite healthy and physically strong.
- Multipurpose Tongue: The long-necked gundarks of Khazet III have long, grasping tongues that they use to grab their prey.
- Non-Indicative Name: "Gundark" is used to refer to numerous alien monsters that bear no relationship with and little to physical similarity to actual gundarks, such as the long-necked gundarks of Khazet III and the aquatic gundarks of Yavin IV, as the original beasts' foul tempers are so infamous that people will use the term to describe new aggressive species that they encounter.
- Noodle Incident: In Attack of the Clones, Obi-Wan mentions an incident where he and Anakin fell into a Gundark nest, but doesn't elaborate on what exactly happened or when this occurred.
- Vertebrate with Extra Limbs: They have three pairs of articulated limbs — four arms and two atrophied legs.
Hawk-Bat
Homeworld: Coruscant
Debut: Jedi Search
Flying predators native to Coruscant, where they nest atop its skyscrapers, hawk-bats are hardy survivors — they're the only members of the planet's native fauna to have survived its transformation into an ecumenopolis, endured millennia of hunting afterwards, and survived the planet's takeover and Hostile Terraforming by the Yuuzhan Vong.
- Fantastic Fauna Counterpart: They're basically alien falcons.
- Mix-and-Match Critters: Their wings, which are membranous and extend to include their hind legs, resemble a bat's, but their overall body shape and beaked heads are more like a bird of prey's.
- No Biochemical Barriers: Hawk-bats feed primarily on Silicon-Based Life such as granite slugs, and are themselves fully edible for carbon-based beings.
- Sole Survivor: On a species-wide level. Hawk-bats are the only species of Coruscant's native wildlife to survive to the present day — everything else on the planet is invasive vermin or escaped exotic pets.
- Super-Senses: Their vision can perceive a very wide spectrum of color, extending into and past the infrared and ultraviolet ranges.
- Vertebrate with Extra Limbs: Newborn hawk-bats have only four limbs, their wings and hind legs. When they mature into adults, they grow a second set of legs just beneath their wings.
Rancor
Homeworld: Dathomir
Debut: Return of the Jedi
Giant predatory beasts, rancors are keenly intelligent beings, enough so as to be considered semi-sentient, but are mostly known to the galaxy for their popularity among dictators and crime lords as pet monstrosities, a role for which they're often starved and tortured into extreme viciousness. As a result of this, feral populations exist on a number of worlds beyond their native Dathomir. Classified as reptomammals, rancors are warm-blooded and bear live young, but are also hairless and do not suckle their offspring.
- Adaptational Intelligence: Precisely how smart rancors are tends to vary between sources. They're usually simply bright animals, but some sources depict them as being intelligent enough to form and pass on genuine oral traditions.
- Eaten Alive: Some rancors eat their prey without bothering to kill them first.
- Even Evil Has Loved Ones: Malakili, Jabba's rancor keeper, is inconsolable when his beloved pet is killed in front of him.
- Fed to the Beast: In the first and most iconic example in Star Wars, the rancor Jabba keeps is used as a means of execution and entertainment in his court.
- Gentle Giant: The jungle rancor subspecies from Felucia and Teth is rather calm and gets along quite well with the locals. They can become aggressive if attacked, however. Even the more infamous Dathomir species is reasonably friendly for large carnivores when not hungry or antagonized and are capable of forming emotional connections with other species.
- Horse of a Different Color: The Witches of Dathomir train rancors to bear them on their backs. The natives of Felucia managed to tame the local jungle rancors in a similar manner.
- Too Hungry to Be Polite: Rancors are normally docile and even reasonably friendly unless threatened. They only turn to wanton violence when starved into a state of desperation. They can also be trained as attack animals but aside from that and starvation they are ultimately no more dangerous then any other carnivorous predator.
- Tragic Monster: The rancors kept by crime lords are typically mistreated, starved and abused, in order to heighten their aggressiveness. Luke himself comes to this conclusion after observing wild rancor and is saddened that he had to kill one due to how vicious the abuse had made it, as it was just as much a victim of Jabba as the people fed to it.
- Top-Heavy Guy: Their upper body is significantly larger than their lower.
- Underground Monkey: A combination of natural evolution and genetic engineering has seeded the galaxy with a respectable number of rancor subspecies, including giant and pigmy versions, the colorful jungle rancors of Felucia, and the aquatic tra'cors.
Vornskr
Homeworld: Myrkr
Debut: Heir to the Empire
Lupine predators native to the forests of Myrkr, vornskrs are among the few naturally-evolved animals known to be Force-sensitive. They use their powers to hunt their prey, the elusive ysalamiri, but will also viciously attack Force-users due to mistaking them for their natural targets.
- Mage-Hunting Monster: Vornskrs react very aggressively to other Force-users, and become hyperfocused on attacking them once they sense their presence; in The Last Command, Talon Karrde makes use of this by using his two pet vornskrs to track down the Dark Jedi Joruus C'Baoth. This is also exploited in the New Jedi Order series by the Yuuzhan Vong, who used vornskrs as one of the base organisms for creating voxyn, engineered monsters intended specifically to hunt and kill Jedi.
- Red Eyes, Take Warning: Their eyes are naturally red, marking out their nature as dangerous and savage predators.
- Savage Wolves: In this case, wolflike alien animals that prowl the forests of an alien world, preying on anyone that enters their domain and relentlessly chasing down Force-users.
- Tail Slap: Vornskr tails are long, whiplike, and coated in a numbing poison. They use them to lash their prey when hunting, seeking to stun and beat it into submission before going in for the kill.
Wampa
Homeworld: Hoth
Debut: The Empire Strikes Back
The primary predator of the planet Hoth, a large, white-furred beast that will attack people if it has the opportunity, but primarily dines on tauntauns.
- An Arm and a Leg: Luke cuts the arm off of the one that captures him.
- Bigfoot, Sasquatch, and Yeti: The wampas' apelike bodies, long white fur and frigid home climate, combined with their horns and solid black eyes, make them look like nothing so much as demonic yetis.
- Spared by the Adaptation: Downplayed with One-Arm, the Wampa that had its arm lopped off by Luke Skywalker. While it was left to an Uncertain Doom in the original film, in the expanded universe it survived with the help of its clan, and eventually became the leader of this group. It would nontheless be Killed Off for Real after trying to attack Luke Skywalker again and failing.
- Horned Humanoid: They are vaguely humanoid, or at least apelike, and have two horns on the sides of their head that point towards their mouth.
- Introduced Species Calamity: Wampa cubs are often exported offworld through the galactic exotic pet trade, and occasionally escape into the wild. Coruscant is home to populations of feral wampas that have established themselves in its polar regions, and which pose a significant danger for tourists and workers there.
- Named After the Injury: The wampa that attacks Luke Skywalker at the beginning of The Empire Strikes Back came to be known as "One-Arm" in expanded universe material.
- Obscured Special Effects: In the original theatrical version of The Empire Strikes Back, only the wampa's head and arms are seen. The Special Edition adds shots of the creature's full body.
- Ursine Aliens: Polar bears seem to have been the primary influence in their design and hunting behavior (stalking their victims while camouflaged against the snow, then attacking out of nowhere).
Naboo
Colo Claw Fish
Debut: The Phantom Menace
One of the large predators dwelling in the subterranean oceans of Naboo.
- Bioluminescence Is Cool: They have bioluminescent patches down their sides.
- Food Chain of Evil: Colos will happily eat young opee sea killers, but are themselves prey for sando aqua monsters.
- Mama Bear: Mother colo claw fishes are extremely protective of their young.
- Mix-and-Match Critters: They have reptilian heads, an eel-like bodies and clawed arms similar to the legs of a crab.
- Monstrous Cannibalism: While mated colos share their lairs, the female needs to chase the male away before the eggs hatch because he will otherwise eat their young.
- Monstrous Mandibles: In the form of what are essentially full-blown, articulated crablike limbs on the sides of their mouths, emphasizing their alien and dangerous nature.
- Sea Monster: They resemble giant eels with a vaguely crocodilian heads and clawed mandibles.
- Swallowed Whole: Colos often consume smaller prey whole and alive. This can prove fatal for them on occasion, such as when they do this to infant opees, which will chew their way back out of the colo.
Opee Sea Killer
Debut: The Phantom Menace
A frightful sea monster that lives in Naboo's oceans.
- Chameleon Camouflage: The first one is seen, it's camouflaged as a rock and Obi-Wan manages to pilot the sub right past it without seeing it.
- Food Chain of Evil: Opees are fearsome predators that will readily attack other animals and submarines alike, but are hunted in turn by the immense sando aqua monsters and their juveniles often fall prey to colos.
- Mix-and-Match Critters: They resemble a mix of a crustacean and a deep-sea fish, with the tongue and eyes of a chameleon.
- Nested Mouths: Opees have two distinct sets of fangs, one in the usual place and a second halfway down their palates.
- Overly-Long Tongue: Their tongues are three times as long as the rest of their bodies when fully extended. The creatures use them to catch prey in the manner of a chameleon.
- Sea Monster: These ferocious, chimeric mixes of fish and crustacean are well over the size of a submarine, and the chance of encountering one of the beasts is one of the biggest dangers in crossing Naboo's subterranean oceans.
Tatooine
Bantha
Debut: A New Hope
A large furry quadruped with long, spiraling horns. They're used as mounts by both offworld settlers and the Tuskens, and also produce blue milk.
- Bond Creatures: Banthas trained by the Tuskens form extremely strong, lifelong bonds with their riders. If the rider perishes, the bantha will usually wander into the desert to die as well.
- Fantastic Fauna Counterpart: In terms of behavior, they're functionally Tatooine's stand-ins for elephants — like them, they're highly social beings with complex social bonds, live in herds led by elder females, and have a form of reverence for the bones of their dead.
- Horse of a Different Color: Banthas are commonly used as war mounts and beasts of burden by the people of Tatooine.
- Mix-and-Match Critters: They resemble a cross between an ox, a ram and a wooly mammoth.
- Multipurpose Tongue: They have a very long tongue tipped with grasping knobs and lined with breathing spiracles, allowing them to multitask as tasting, grasping, scenting, and breathing organs. Males also use tongue positioning to signal willingness to mate.
Krayt Dragon
A canyon krayt dragon
Debut: A New Hope (skeleton),
The apex predators of the planet Tatooine. They come in two subspecies: the smaller and more common canyon krayt dragon, which lairs amidst rocky badlands, and the much larger greater krayt dragon, a rarely seen behemoth of the deep sand seas. They are known for their prized pearls inside their bodies, though getting them is easier said than done due to their feared reputation for the Tatooine denizens.
- Attack Its Weak Point: In "Skin Deep: The Fat Dancer's Tale", a krayt dragon is killed when the Geranite huntsman Doallyn (who'd studied the species extensively in preparation for hunting and capturing one for Jabba) does this — he fires a single blaster shot into its sinus cavity, which leads directly to its brain.
- The Dreaded: Everyone on Tatooine fears the greater krayt dragon, even the Tusken Raiders. When three of them hear Obi-Wan's imitated roar of a Greater Krayt, they immediately flee without second thought.
- Elephant Graveyard: Krayt dragons that sense death approaching instinctively head to the Krayt Graveyard, a hidden valley littered with the massive bones of the great reptilian beasts. Treasure-hunters occasionally seek it out in hopes of finding rare Krayt pearls laying among the remains, but few ever return.
- Food Chain of Evil: The greater krayt dragon is the undisputed top predator of Tatooine, and even the almighty sarlacc is just a meal for these creatures.
- Formerly Sapient Species: While it's not explicitly confirmed, it's speculated in-universe that the krayt dragons are an offshoot of the Duinougwuin, a species of intelligent, Force-sensitive spacefaring dragons with the unfortunate tendency to occasionally birth mutated or bestial offspring.
- Our Dragons Are Different: In this case, they're multi-legged reptilian titans that swim through desert sands like whales and are the uncontested apex predators of an alien planet. They also produce valuable pearls within their bodies, a trait shared with Greco-Roman dragons.
- Ribcage Ridge: A greater krayt dragon's skull and spine can be seen when C-3PO wanders through the Dune Sea in A New Hope.
- Rite of Passage: For a Tusken Raider to become an adult, they must hunt a canyon krayt dragon and claim its pearl.
- Vertebrate with Extra Limbs: Greater krayt dragons have ten legs.
Sarlacc
Debut: Return of the Jedi
Sarlaccs are massive, largely immobile creatures that feed on whatever falls into their dens. Their victims are integrated directly into their bodies, and the creature feeds on their minds as well as their flesh. Over time, some ancient sarlaccs form piecemeal minds of their own from fragments of their prey's.
- Always a Bigger Fish: Sarlaccs on Tatooine are known to fall prey to the immense greater krayt dragons.
- Antlion Monster: A gigantic version — adult sarlaccs dig deep pits from which they ambush prey, using their tentacles to drag their victims into their maws.
- And I Must Scream: A sarlacc's victims spend a solid millennium being digested alive while kept paralyzed in constant agony by a potent neurotoxin.
- Bizarre Sexual Dimorphism: The aggressively predatory sarlaccs commonly seen are females — males are much smaller and live parasitically off their mates.
- Combat Tentacles: Sarlaccs have long tentacles that they use to catch their prey. Their larval forms are nothing more than a mass of hungry, grasping tendrils, as well.
- Emotion Eater: In addition to physically consuming their prey, sarlaccs are speculated to drawn sustenance from the fear and suffering of their victims.
- Lamprey Mouth: A sarlacc's main mouth is a circular maw with sharp needle-like teeth that point inwards to prevent prey from climbing out.
- Nested Mouths: They have two mouths. One is the giant maw of sharp teeth that is visible on the surface of the pit. The second is a retractable beak-like tentacle that lies in the center, waiting swallow the unfortunate victim and make escape practically impossible.
- Swallowed Whole: A sarlacc's prey is dragged into its maw alive and whole.
- The Symbiote: Sarlaccs are known to form mutualistic associations with the vulture-like urusai. The urusai nest in the sarlacc pit itself, enjoying the formidable being's protection and eating scraps from its meals in exchange for cleaning the beast's pit, tentacles and fangs from the remnants of its prey.
Outer Space
Exogorth
Debut: The Empire Strikes Back
"They're the last remnant of a species that predates history — an unlikely being, if ever there was one. No one knows how or why they evolved — just that we have found a number of them in the galaxy, going about their business... time has no meaning for such a creature... we thought for a time that they might have once been plentiful in the galaxy — and the ones we find now are the only ones left."
Arkoh Adasca, Knights of the Old Republic
Also known as space slugs, exogorths are massive creatures that live in asteroids.
- Bizarre Alien Biology: Silicon-based creatures live in the vacuum of space. They subsist in equal parts on passing ships and creatures and on solar radiation and minerals from their asteroids.
- Bizarre Alien Reproduction: They reproduce by splitting in two like an amoeba.
- Food Chain of Evil: Despite their size and power, space slugs are themselves prey for even larger spaceborne organisms such as Ithulian colossus wasps.
- Silicon-Based Life: They're described as being "more mineral than animal".
- Space "X": Their common moniker of space slugs. Justified in their case, as they live in the vacuum of space itself.
- Swallowed Whole: The fate of the ships, crews and creatures they catch. The largest ones have been known to house ecosystems in their bellies.
- Taken for Granite: They turn to stone when they die. Many asteroid caves are thought to be dead exogorths.
- That's No Moon: While trying to escape the Empire, Han lands the Millennium Falcon inside the stomach of one, mistaking its mouth for a cave on an asteroid.
Mynock
Debut: The Empire Strikes Back
Batlike creatures that can live in the vacuum of space. They're infamous for their habit of infesting ships to feed on their energy supplies.
- Abnormal Allergy: They're extremely allergic to helium, a normally entirely nonreactive and inert gas, which causes them to inflate to the point of nearly exploding. This is exploited by mynock exterminators, who use helium grenades to deal with mynock infestations.
- Artistic License – Chemistry: They're intensely allergic to helium, and die nearly instantly on contact with any amount of it; this is stated to be the primary reason why they can't establish themselves on planets. Helium is a noble gas, a class of elements notable mainly for their intense inertness and difficulty in reacting with any other substance, which makes it very difficult for them to have any effect, good or ill, on a living organism, and for being rare to the point of nonexistence in planets due to its lightness making it impossible for most planetary gravities to keep it from leaking off into outer space.
- Bizarre Alien Biology: Silicon-based lifeforms that eat electromagnetic and stellar energy, live in the void of space, and reproduce by splitting in two. They're also deathly allergic to helium gas, which is why they avoid planetary environments and stick to hard vacuum.
- Bizarre Alien Reproduction: They reproduce by splitting in half, with each half growing into a new mynock.
- Fantastic Diet Requirement: Mynocks feed directly on energy. In their natural environment, they subsist mainly on stellar energy emissions, but they will happily siphon off power from spaceship power circuits as well.
- Fantastic Vermin: Their energy-based diet makes them this for spaceship crews, as they will readily latch themselves onto ships to siphon energy from them. One or two mynocks are a nuisance that will harm a ship's efficiency; a large infestation can leave a vessel powerless and dead.
- Lamprey Mouth: Their mouths are circular and ringed with short tendrils.
- No Biochemical Barriers: Despite being silicon-based, they can be eaten by carbon-based beings, provided enough seasoning.
- Too Many Mouths: Some mynock variants have two mouths — a jawed one in the normal place, and a Lamprey Mouth on their upper chests.
Sithspawn
Sithspawn are unnatural monsters created by the Sith through genetic engineering, alchemy, and sorcerous warping. Most forms of Sithspawn are designed to serve as guardians, Jedi hunters or weapons of war, all roles that they excel at. For the most part, the techniques for creating these beings became lost over the long ages, but the creatures themselves often proved tenacious and endured long after the downfall of the Sith lords that shaped them. Rakghoul
Homeworld: Unknown
The rakhgouls are the creations of the ancient Sith Lord Karness Muur, who designed them to serve as an inexhaustible army for himself. All rakhgouls are former sapient beings, transformed by either the dark influence of the Muur Talisman or by the plague carried in the teeth and claws of mature rakhgouls. A few beings, such as Force-sensitives and certain alien species, are immune to the Talisman's effect, but not to the plague. These beings have emerged as deadly plagues at several points in history, each time marking the Talisman's emergence.
- Depending on the Artist: Depictions of rakghouls are somewhat inconsistent — primarily, not all artists agree on whether they retain their eyes or not.
- Eyeless Face: In some depictions, transformation into a rakghoul results in the complete loss of the eyes, which are replaced with unbroken patches of skin, flesh and bone.
- Gameplay and Story Segregation: In-lore, being bitten by a rakghoul transmits a disease which transforms that person into a rakghoul if not healed early with a specific serum. During actual fights in Knights of the Old Republic, when someone from the player's team is hit by a rakghoul there is a random probability that they'll be affected by a standard poisoning effect, which disappears after a few minutes and can be cured with standard antidote packs.
- Our Ghouls Are Different: In addition to being named after ghouls, they share their common depiction as hunched, deformed, cannibalistic monsters.
- Our Zombies Are Different: Rakghouls are largely a zombie stand-in for Star Wars' space fantasy setting. They're former humanoids transformed by a plague that turns them into bestial, savage monsters, and reproduce by infecting others with their bites and claws.
- Primal Stance: Rakghouls tend to stand in a hunched-over, apelike stance, and often drop to all fours when running.
- Shapeshifting Sound: In Knights of the Old Republic, people who've been infected with the rakghoul plague and don't get a dose of serum in time will metamorphose into ravenous mutants with a dazzling flash of light, a glowing cloud similar to an ion grenade, and a loud "whooshing" sound effect.
- The Virus: Rakhgouls propagate mainly through the rakhgoul plague, which they spread through their bites and claws and which will cause those so afflicted to transform into new rakhgouls.
- Was Once a Man: As rakghouls don't reproduce naturally, every specimen encountered was once a sapient humanoid before the Muur Talisman or the plague turned them into a monster.
Terentatek
Homeworld: Unknown, possibly Korriban or Dromund Kaas
Monsters resembling smaller, spike-covered rancors and infamous for feeding preferentially on the blood of Force-sensitives, terentateks were created by the ancient Sith at some point before the Great Sith War. These beasts were planted on countless worlds by their masters, and despite multiple attempts by the Jedi to exterminate them, enough always survive in the dark corners of the galaxy to repopulate their kind once the Sith inevitably reemerge.
- Anti-Magic: Terentateks are almost impossible to affect with Force-based powers.
- Bioweapon Beast: They were created by the ancient Sith to serve as living weapons against the Jedi.
- Fantastic Diet Requirement: They were created to need to feed on the blood of Force-sensitive beings, in order to drive them to attack the Sith's enemies.
- Mage-Hunting Monster: Terentateks were created by the Sith for the express purpose of hunting Jedi. To do this, they were designed to feed primarily on the blood of Force-sensitives, giving them a motivation to hunt them, and were made almost entirely immune to Force effects.
- Red Baron: Their power, danger, and effectiveness at hunting Force-users led to them being referred to as the Jedi Killers.
Tuk'ata
Homeworld: Korriban
Debut: Tales of the Jedi
Tuk'ata, also called Sith hounds, are monstrous canine beasts created by the Sith to guard their tombs and temples. The largest populations exist on Korriban, where they teem among the planet's ruins and necropoleis, but they can be found through the galaxy wherever the ancient Sith had presence.
- The Ageless: They're believed by some to be physically immortal, as many are found alive and well inside the same sealed tombs in which they were enclosed millennia in the past.
- Androcles' Lion: In Star Wars: Invasion 2, a group of Jedi initiates on Yavin IV is attacked by a tuk'ata when they encroach on its cave. During the confrontation, Jacen notes a piece of wood embedded in its side and, when the beast is distracted attacking someone else, he darts in to remove it. The tuk'ata largely calms down after this, and retreats back into its cave.
- Hellhound: Of the Guardian kind, being ferocious, hound-like monsters created by ancient Sith to be relentless, fearsome guardians for their tombs.
- Red Eyes, Take Warning: Among the tuk'ata's most notable features are their glowing red eyes, which mark them as creatures of the Dark Side. Notably, the only known pair of Light Side-aligned tuk'ata, which guarded a Jedi temple, had blue eyes instead.
Yuuzhan Vong creatures and biotechnology
Because of their hatred for all mechanical based-technology and of their mastery of biotechnology, the Yuuzhan Vong make use of a great variety of animals, plants and other kinds of living beings that they imported from their home galaxy, or that their shapers created with their unmatched mastery of genetics. These creatures used by the Vong range from beetles to titanic monsters, passing by biological weapons to blobs. Voxyn
Homeworld: Myrkr
Debut: Star by Star
The Voxyns are a genetic cross between the Vornskr and the Fero Xyn, a creature from the Yuuzhan Vong galaxy. They were bred specifically to hunt down and kill Jedi, the Voxyn are terrifying hunters that are perfectly made for their role, with their ability to sense Jedi from a long range via the Force, even when Jedi attempt to cover their presence, their acidic saliva, their sonic scream, poisonous fangs, claws and tails and their incredible agility and speed.
- Bioweapon Beast: Voxyns were created by the Yuuzhan Vong specifically to hunt and kill Jedi, and they are very capable of doing so.
- The Dreaded: They quickly become feared by the Jedi, with Voxyn's presence within the Force being one of the few things that can terrify them; and to the point that Luke Skywalker and Han Solo agree to launch a suicide mission with their own children/nephews and niece to end the Voxyn's production, out of fear that the Voxyns would end the Jedi if able to live on.
- It Can Think: What makes Voxyn so efficient and terrifying predators, other than their many gifts and weapons, is that they are very intelligent. They are capable of using elevators and to learn how to hide their own presence in the Force from Jedi to better hunt and surprise them.
- Mage-Hunting Monster: Like the Terentateks by the ancient Sith, Voxyns were made by the Yuuzhan Vong to hunt down and kill Jedi, and they are very efficient at it too. Not only they are able of tracking Jedi down even when Jedi try to hide their presence within the Force, but their fangs, claws and tails are venomous, they are incredibly fast and agile, are hard to kill even with a lightsaber, their saliva is acidic, they have a sonic scream and they never stop hunting their prey down.
- Nigh-Invulnerable: They are very tough and durable, able of taking blaster shots, being crushed by debris and even taking some lightsaber hits without being grievously injured or killed.
- No-Sell: Jedi are usually able of evading most people and even other Force users by reducing or even totally hiding their presence within the Force, but this doesn't work on Voxyn who can sense them no matter what the Jedi do to hide.
- Super-Persistent Predator: Not only they can sense the Jedi through the Force, but they can also detect them even when Jedi hide their presence within the Force, and they never stop hunting Jedi after having detected them.
