This page is part of the character sheet for Starfinder, covering non-playable Ooze creatures.
A broad category of creatures united mostly by being naturally amorphous and lacking specialized body parts, existing as living masses of various substances. Most that aren't masses of protoplasm are liquids or colloids of some sort or another, but gaseous and plasma-based oozes also exist.
To see the tropes for oozes in Pathfinder, see Pathfinder Oozes.
- Blob Monster: All oozes have amorphous, mutable bodies.
Player-Sized
- Anti-Magic: Noqual eaters gradually nullify magic in their surroundings.
- Metal Muncher: Each starmetal eater subsists on one specific type of starmetal.
- Yin-Yang Bomb: Siccatite eaters maintain an improbable balance between cold and heat.
CR 1/2
- Abstract Eater: Polyphonic gels seem to draw some nutrition out of physical material, but primarily feed on sound.
- Vibroweapon: Polyphonic gels' bodies course with sonic vibrations that can devastate flesh, bone and steel as well as break prey into edible chunks.
- Objectshifting: A proog can look like any solid object that it comes into contact with. It can't imitate functions, moving parts or the like.
CR 1
- A.I. Is a Crapshoot: Due to sloppy programming, the code embedded within an assembly ooze has an unfortunate tendency to become corrupted, causing the ooze to haphazardly deconstruct any nearby tech and use the pieces to build random items. These oozes are the bane of every place where technological devices are present.
- Grey Goo: Due to the presence of reproduction programming, a rogue assembly ooze introduced into an environment stocked with technological items could completely overrun such a place in days, leaving behind a wasteland of cheap laser pistols and smoke grenades.
- Mobile Factory: Assembly oozes are designed for the purpose of constructing technological devices.
- Nanomachines: An assembly ooze consists of a nanobot core suspended within a blob of animated protoplasm.
- Non-Malicious Monster: Assembly oozes hold no innate malice despite being massive pests.
CR 2
Ferromagnetic fluid, or ferrofluid, has long been a staple of spacefaring technology. Societies across the galaxy originally created this utilitarian substance by suspending coated nanometer-sized particles of magnetite in viscous liquid. As necessity demanded invention, later iterations of the magnetic liquid began to take on an almost lifelike temperament. The substance increasingly exhibited erratic behavior as engineers tinkered with heavily magnetized liquids, using experimental bioengineered substances to suspend magnetic particles. The final result of these developments was an emergent, though limited, sentience within certain pools of ferrofluid—a consciousness solely consumed with the search for ever-stronger magnetic fields.
- Fusion Dance: Given enough time and magnetic material, multiple ferrofluid oozes can form into a single, much larger magneto-cluster.
- Acid Attack: The liquescence hunts by enveloping small prey or pouring itself into large prey with its acidic body to slowly digest over time. The chemical makeup of these acids has resulted in an active secondary market in infiltration, weapon and cleaning industries.
- Invisible Stomach, Visible Food: In their native Plane of Water, liquescences are translucent and nearly impossible to spot, though this is easier after they have fed, with the decomposing remains of their food slowly digesting within.
CR 3
Purportedly born from some ill-informed experiment performed during the Gap, bodysnatcher slimes are parasitic organisms that commandeer hosts to experience life through their senses.
- Puppeteer Parasite: The bodysnatcher slime is a parasitic organism that can distribute itself throughout another creature's body and control the host's actions.
- Split Personality: As a bodysnatcher slime grows, its modified neural network can develop multiple personalities that compete for resources and control, and eventually split into two new slimes.
- Immune to Fire: Adapted to living in undersea volcanic vents, thermophilic oozes are immune to fire.
CR 5
Carnivorous flying oozes found on many worlds.
- Chameleon Camouflage: They change color to match their surrounding atmosphere, typically appearing as clouds or mist, though they can't do so when they're digesting something.
- Flight: They're naturally buoyant, floating on wind currents even if unable to take actions.
- Anti-Magic: Noqual fragments embedded in it sbody provide a void slime with a measure of protection against magic and allows its pseudopods to dispel magic from those it strikes.
CR 7
- Hoist by His Own Petard: A captured liquid arsenate is more likely to turn on its keepers than remain docile. Black-market poisoners constantly look for ways to safely contain liquid arsenates without diluting their poison, but none have been able to devise a reliable method of captivity. Those that prefer punitive justice believe that liquid arsenate farmers who end up poisoned by them more than deserve their fate.
- Poisonous Person: A liquid arsenate's pseudopod inflicts a concentrated dose of arsenic.
Magma oozes are living pools of bubbling molten rock that churn and move of their own accord.
- Living Lava: They're living pools of molten rock commonly found on the border regions of the Planes of Earth and Fire and in the vicinity of volcanoes.
- Taken for Granite: Water turns them to stone, leaving them unharmed and immobile until the water is gone.
Disease given physical form, plague oozes are most commonly found on the living planet of Aucturn.
- The Virus: Contact with a plague ooze can spread ooze plague. Without an immediate cure or quarantine, asymptomatic carriers can infect others, eventually transforming into a plague ooze after they die. This continues as a ghastly epidemic, even long after the source ooze was destroyed.
- Glamour Failure: When a replicant ooze loses more than half of its total Hit Points, it immediately reverts back to its true form.
- Human Shifting: A fresh brain or similar organ allows a replicant ooze to shape its own biomass into a replica of the donor. When a replicant ooze duplicates a person, it often doesn't realise it is an impostor and attempts to live out the victim's daily life.
Oozes originating from deep space in the Shadow Plane.
- Asteroids Monster: When they regain more hit points than thier maximum thanks to their shadow siphon ability they split in two with the hit points divided evenly between them.
- Batman Can Breathe in Space: They can survive in a vacuum indefinitely with no negative side effects. This trait allows them to act as extraterrestrial remoras, floating in space and hitching a ride on ships that pass nearby.
- Brown Note: Getting hit by one of their pseudopod attacks and failing an accompanying save renders all of a creature's senses nonfunctional for one round.
- Casting a Shadow: Light is automatically reduced around them and they heal whenever a dying creature looses a resolve point while in this aura.
CR 8
The aggressive and insightful genetic manipulators known as thorgothrels enforce their vision of retrogressive development on other species.
- Deflector Shields: A thorgothrel's internal armatures create an invisible field around it.
- Devolution Device: A thorgothrel can alter a target's genetic structure to induce rapid evolutionary regression. As the target mentally regresses, it also becomes more feral and violent.
CR 9
- Defeat Equals Explosion: When a detonation ooze is destroyed, the unstable chemicals that make up its body trigger a violent explosion.
- Make My Monster Grow: A detonation ooze is made of highly unstable chemical compounds that begin to break down, causing it to expand in size, as it takes damage.
- Hidden Agenda Villain: Hymothoas have shown little interest in communicating with other species, and little is known about why they infest certain creatures.
- Puppeteer Parasite: A hymothoa can infest a victim's body and devour internal organs, bones, and even parts of the brain. The hymothoa then mimics the function of those organs, essentially turning the victim into a barely living puppet. When abandoned by the hymothoa, the victim almost always dies; the rare few survivors need a lengthy stay in hospital to replace lost organs.
- Flash Step: A memory muck can momentarily slip through the Astral Plane to materialise next to another non-mindless creature.
- My Skull Runneth Over: A memory muck's strikes are charged with hundreds of memory fragments from dozens of minds, which can overwhelm the minds of its enemies.
- The Assimilator: The rare gene-scavenger slimes construct shells from parts of whatever creatures they encounter, incorporating abilities from various species.
- The Engineer: Scavenger slimes can patch or repair nearly anything they encounter.
- Improvised Armour: Scavenger slimes build protective shells for themselves out of refuse and their own natural resin, incorporating bits of repaired technology as they go.
CR 10
A sentient and malevolent hue that defies classification and eludes identification by most sensors.
- Body Horror: A victim of the colour is hideously deformed and glows with the same unnamable colour as the creature that blighted it.
- Energy Beings: A colour has no physical body at all.
- Fictional Colour: The colour's glow is unlike any seen in nature.
- Bioweapon Beast: Magazine oozes might have been created as living weapons by an unknown civilisation to cause havoc among enemy military encampments.
- Reliably Unreliable Guns: A magazine ooze can distribute itself throughout a firearm, causing it to randomly discharge when unattended or shift its aim to shoot another target when fired, and allowing itself to jam the gun muzzle.
CR 11
Originating from the Plane of Earth, these oozes convert both living and nonliving materials into the crystals they eat.
- Crystalline Creature: These creatures are living crystalline formations.
- Taken for Granite: A creature entrapped by a carnivorous crystal's attack eventually crystallises and shatters, and a new carnivorous crystal emerges from the remains.
CR 13
Oozes formed from a bizarre symbiosis of living material and technology. Typically confined to crystalline containers that keep them from coming apart, they serve as living computers for the starships of the Dominion of the Black.
CR 15
Researchers who experiment too recklessly with quantum forces run the risk of spontaneously creating a quantum slime, an incredibly dangerous ooze composed of enlarged subatomic particles floating inside a mass of cloudy protoplasm-like goo. Though mindless, a quantum slime has the ability to alter reality at a quantum level, calling forth storms of cosmic energy, teleporting itself and others, or diminishing a creature’s overall competency.
- Self-Duplication: A quantum slime can form a quantum-entangled copy of itself. The copy is identical to the original, and the two slimes share a single HP pool. The quantum slime can dismiss one copy when it is about to take damage, causing the other to become the 'true' version.
CR 16
Powerful beings of living plasma most often seen in the immediate vicinity of a star’s surface, plasma oozes are significant threats to even the Pact Worlds’ most experienced spacefarers.
- Walking Techbane: A plasma ooze generates a massive electromagnetic field that disrupts electronics and interferes with signals.
CR 18
- Invisible Monsters: An exhaust ooze is composed of transparent gas.
- Poisonous Person: An exhaust ooze can batter prey with a torrent of foul gas.
CR 20
- Atomic Superpower: A living apocalypse commands energy rays of pure radioactive force.
- Omnicidal Maniac: Once a living apocalypse is unleashed, it destroys everything in its path until there is no complex structure or significant lifeform left within hundreds of miles.
Starship-Sized
A photonic anomaly is “born” when two or more infinitesimal gamma rays, each traveling a few millimeters in a random direction, happen to match trajectories perfectly. The cluster continues to dart randomly around the interior of the star until another nearby protophoton or gamma ray cluster again travels in the same direction, after which the two combine. Over millions and millions of years, these clusters can grow into a starship-sized entity that roams its home star.
- Energy Beings: A photonic anomaly is composed entirely of gamma rays.
- Abstract Eater: A cerebrex can digest both the physical matter of its food and a fragment of its sapience.
- Cannibalism Superpower: After feasting on entire civilisations, a cerebrex briefly takes on an almost-humanoid intelligence, just long enough to plan its next attack.
- To Serve Man: Cerebrexes search for clusters of sapient life to feast upon.
