Once Human Deviants: Introduction
Deviants
Twisted by Stardust and driven by chaos, these mutated creatures stalk the wilds with deadly intent. Their forms vary wildly, each more unsettling than the last. Facing Once Human Deviants takes courage—but the rare loot and materials they drop make the risk worthwhile.
Once Human Deviants are powerful, mutated enemies twisted by the Stardust. These dangerous foes challenge players with unique abilities and drop valuable loot upon defeat. Facing a Once Human Deviants often means preparing well—or dying fast. Once Human Deviants are the twisted remnants of humanity, Once Human Deviants are transformed by the mysterious and corrupting force known as Stardust. These Once Human Deviants, once fully human, have become something else entirely—monstrous, dangerous, and unpredictable. Throughout the world of Once Human, players encounter countless variations of Once Human Deviants, each with unique mutations, behaviors, and combat tactics that challenge even the most experienced survivors.
List of Deviants in Once Human
The presence of Once Human Deviants serves as a constant reminder of the cost of the Stardust infection. Unlike ordinary enemies, Once Human Deviants are driven by a mix of lingering human instincts and alien corruption, making them unpredictable foes that require careful strategy. Many Once Human Deviants retain echoes of their former lives, but those traces are often twisted into violent or desperate actions. Understanding the nature of Once Human Deviants is crucial for survival. Their mutations grant them special abilities that can disrupt player tactics, such as stealth, poison, or explosive attacks. Combat against Once Human Deviants often demands adaptability and awareness, as these creatures use the environment and their unique powers to their advantage.

Beyond their gameplay challenges, Once Human Deviants embody the thematic core of the game’s story—illustrating the tragedy of humanity’s downfall and the lingering shadows of a lost civilization. They represent both a warning and a testament to the dangers of unchecked corruption and the persistence of life in a broken world. Players will find that Once Human Deviants are not just obstacles but living symbols of the game’s world-building, with each type offering insights into the world’s lore and the fate of those who fell victim to Stardust. Facing Once Human Deviants means confronting the harsh reality of transformation, loss, and the struggle to maintain humanity amid chaos.
In every encounter with Once Human Deviants, players engage with the consequences of a world changed forever. Whether it’s the cunning Burrower, the relentless Charred Maniac, or the deceptive Agent, each Once Human Deviant tells a story of mutation, survival, and tragedy. Mastering the threats posed by Once Human Deviants is a key step toward reclaiming hope in a shattered landscape.
Agent
Agent
Agents drone on and on, but can only produce a hollow rasp. They wear black suits, and have a briefcase with a large mouth a long tongue in place of a head that drip[s] slimy saliva. Agents can spit their saliva like a cannonball. Their spit is mixed with moist and decaying banknotes, and in this post-Starfall world, they are perhaps the only ones to cling to money of old.
- Type:Deviant
-
Drops
- Loot from Agents are the same as other deviants, consisting of various junk items and acid.
- Ammunition and firearms parts.
- Experience points and occasionally currency or crafting components.
-
Location:
- Military Checkpoints: Heavily fortified zones with patrols.
- Abandoned Facilities: Research labs or bunkers with security forces.
- Conflict Zones: Hotspots of human-Deviant conflict.
- Outposts and Safehouses: Strategic locations where Agents enforce control.
The Agent is a humanoid Once Human Deviants that appears both eerie and satirical in design, dressed in a tattered black business suit that mocks the image of a corporate worker. Its most disturbing feature is its head — or lack thereof. In place of a normal skull sits a malformed briefcase-like appendage, complete with hinges and a grotesquely wide mouth that stretches across its surface. Inside the gaping maw is a grotesque tongue that lashes out, and bits of decaying paper money often ooze from its jaws, suggesting it’s literally consumed by a hunger for wealth and power.

This Once Human Deviants, the Agent doesn’t just symbolize greed — it weaponizes it. The Agent emits a hollow, metallic rasp as it approaches, a chilling echo of a dying voice once used to close deals and sign contracts. Its primary attack involves projectile vomiting a bile-like saliva laced with shredded, moldy banknotes — a mix of biological corruption and human-made currency that burns on contact and disorients the target. These attacks can leave players slowed or confused, representing how obsession with money blinds and weakens even the strong.
Weaknesses
Agent
Agents rely heavily on speed and stealth, but their biggest drawback is low durability. If caught in the open, they fall quickly to concentrated fire. Their stealth breaks easily when they move, especially through illuminated zones. Long-range weapons like DMRs or thermal scopes can expose and eliminate them before they close the gap. Keeping your distance is key to neutralizing their threat.
In combat, the Agent—and other cunning Once Human Deviants like the Auditor, Headcase, and Slipmask—exhibit cold, calculated behavior. They often patrol areas as if they own them, moving with territorial confidence. When provoked, they strike fast and erratically, slashing with claws or smashing forward with their briefcase-like heads. Some may even retreat briefly, only to return with ranged bile attacks, keeping players on their toes and constantly on the move.
Symbolically, the Agent—and other Once Human Deviants like the Slipmask, Foreman, and Desk Jockey—represent the ghost of corporate identity: lifeless, mechanical figures still grinding away at obsolete roles in a world that no longer needs them. Defeating these entities isn’t just about survival; it’s a small act of defiance against the lingering echoes of a collapsed and irrelevant order.
Budworm
Budworm
The Budworm is a small, flying Once Human Deviants known for its role in boosting agricultural productivity. Capturing and housing Budworms in your territory increases the chances of crops becoming deviated, helping you craft rare recipes and gather valuable resources more efficiently. While not aggressive, they add a strategic farming advantage in Once Human.
- Type:Deviant
-
Drops
- Territory Aesthetics: Enhancing the visual appeal of your base with its glow.
- Mood Boost: Improving the morale of other housed Once Human Deviants.
- Resource Attraction: Increasing the spawn rate of certain luminescent plants nearby.
-
Location:
- Citrus County: Near the pumpkin patch field adjacent to the barn.
- Sutherland Family Orchard: On the eastern side of the hedge vine area, directly south of the Rift Anchor.
- Evergreen Vineyard: A vineyard setting where Budworms have been spotted.
- Sunbury Farm: Known for its agricultural landscape, making it a potential spawn point.
The Budworm is a peculiar and seemingly harmless Deviant, no larger than a bird, with iridescent wings and a segmented body that glows faintly in the dark. Though it flits gently through the air like a moth drawn to moonlight, don’t mistake its delicate appearance for uselessness — this creature plays a vital role in the strange ecosystem left behind by Stardust.

Budworms are agricultural anomalies. Unlike most Once Human Deviants, they’re not aggressive and won’t attack unless provoked. Instead, their presence brings strange benefits. When housed properly on a player’s homestead, Budworms enhance crop mutation rates — essentially encouraging plants to evolve into more potent or exotic versions of themselves. The mutations they inspire are unpredictable but highly valuable, making Budworms a key asset for players who focus on farming, crafting, and rare material production.
Weaknesses
Budworm
Budworm’s hardened carapace provides solid frontal protection, but it’s highly vulnerable from behind. Its turning speed is sluggish, making flanking an ideal tactic. Fire-based weapons are particularly effective at breaking through its outer shell. Additionally, Budworm can be baited into charging, which leaves it momentarily exposed if it misses. Staying agile and attacking from the sides will quickly wear it down.
They’re most commonly found near mutated flora, buzzing lazily between glowing blossoms or resting on oversaturated vegetation. Their wings beat in rhythmic pulses, releasing faint spores that accelerate plant growth or subtly alter its genetic makeup. Some in-game theorists even suggest that Budworms were once pollinators, now twisted by Stardust into Once Human Deviants—reengineered to serve a strange new ecological purpose.
Symbolically, Budworms represent the blurred line between corruption and adaptation. Unlike the grotesque, violent Once Human Deviants that dominate the world, Budworms show how the same alien force — Stardust — can also create harmony, given the right context. They’re gentle remnants of nature’s will to survive, reshaped by chaos but still life-affirming at their core.
Burrower
Burrower
The Burrower is a fast, stealthy underground Deviant known for sudden, surprise attacks from beneath the surface. These creatures use hit-and-run tactics, burrowing underground to avoid damage and then erupting to strike unsuspecting players. While not a boss, they provide a significant challenge due to their agility and unpredictability.
- Type:Deviant
-
Drops
- Crafting materials (metal scraps, organic matter)
- Experience points
- Occasionally components used for gear upgrades
-
Location:
- Dayton Wetlands: Near swampy, muddy grounds.
- Broken Delta: Around riverbanks and eroded cliffs.
- Chalk Peak: Rocky areas with loose soil.
- Overgrown City: Urban ruins with cracked pavement and debris.
The Burrower is a stealthy and dangerous Deviant that uses the earth itself as its battlefield. Unlike many of the more visibly grotesque creatures, the Burrower spends much of its time hidden beneath the surface, emerging only to strike with sudden, brutal force. Its insect-like body is sleek and armored, with powerful limbs adapted for rapid digging and swift movement through soil and rubble.

This creature is one of the more elusive Once Human Deviants, excelling at surprise attacks by lying in wait underground before erupting beneath its prey. Its strikes are lightning fast—raking at exposed legs or ankles, with a venomous bite that slows or weakens its target. The Burrower’s agility lets it slip back beneath the surface before enemies can respond, making it one of the most frustrating Once Human Deviants to pin down in open combat.
Weaknesses
Burrower
The Burrower relies heavily on its ability to ambush from underground, but it leaves behind noticeable movement trails before surfacing. Its emergence delay gives alert players a window to dodge or pre-aim. Area-of-effect (AoE) explosives and flame weapons can force it to surface prematurely or deal damage while hidden. Once above ground, it’s slow and easy to kite. Staying mobile and using traps can shut it down fast.
When dealing with Burrowers and other Once Human Deviants like Crawlers, Tunnel Howlers, and Pitlings, players need to stay alert for subtle clues—rippling ground, minor tremors, or rustling foliage can all signal an impending ambush. Due to their hit-and-run tactics, using crowd control and area-of-effect abilities is key, helping to expose these elusive enemies or damage them while they’re still underground.
Symbolically, the Burrower embodies the unseen dangers lurking beneath the surface — threats that avoid direct confrontation but strike with ruthless efficiency when given the chance. It represents the cunning and adaptability of the Once Human Deviants, using stealth and speed over brute strength to survive in a hostile world.
Charred Maniac
Charred Maniac
The Charred Maniac bears clear external signs of mutation, showing it has already become something less than human. Yet, if you look closely, occasional glimpses of the person within can still be seen. This is the first stage of transformation after a human embraces Stardust. Charred Maniacs are characterized by withered muscles, festering skin, long hyperplastic arms, weakened legs, cloudy eyes, and a crooked jaw. There’s an unsettling, uncanny valley quality about them.
- Type:Deviant
-
Drops
- Chance of dropping Acid
-
Location:
- Charred Maniacs are low-ranking enemies, commonly found throughout Nalcott.
The Charred Maniac represents the earliest and most tragic stage in the horrifying transformation from human to Deviant under the influence of Stardust. Once an ordinary person, the Charred Maniac is now a grotesque figure — its flesh blackened and burned, muscles torn and exposed, with skin cracked like scorched earth. This warped body shows signs of violent mutation, its limbs twisted and elongated, often ending in clawed fingers that twitch with restless energy.

Its face is a cruel distortion of human features: a crooked jaw that hangs slack or snarls with malice, and eyes sunken or glowing faintly with unnatural light. Though its humanity is almost entirely lost, occasional glimpses of former self-awareness flash in its movements — a painful reminder of what it once was.
Weaknesses
Charred Maniac
The Charred Maniac thrives in close quarters with its burning melee attacks but has minimal defense against ranged firepower. Its erratic charge patterns are predictable once learned, making it vulnerable to strafing and kiting. Cold-based weapons or cryo abilities can slow or halt its advance effectively. It also lacks armor, meaning even mid-tier bullets can chunk its health. Keep your distance and punish its reckless aggression.
The Charred Maniac is one of the more feral Once Human Deviants, moving with erratic, explosive energy fueled by a burning rage and an insatiable drive to spread the Stardust contagion. Its attacks are savage and unhinged—slashing with jagged claws, biting with ferocity, or unleashing a piercing scream that disorients anyone nearby. As with many Once Human Deviants, its chaos is its weapon, making it a relentless force that overwhelms through fear and sheer aggression.
Symbolically, the Charred Maniac represents the rawest form of destruction and loss—a once-human figure now driven by self-consuming rage and alien corruption. Like many Once Human Deviants, it serves as a grim warning of what becomes of those who succumb entirely to Stardust’s influence: monsters caught in a violent struggle between fading humanity and the unnatural force that has overtaken them.
Customer
Customer
No longer will they have to worry about overtime, delayed orders, deadlines, emergency requests, and accident reviews. All that’s left is to zone out and enjoy the amusement park. Anyone who receives a balloon from an Ede will transform into a Customer. With their burdened heads replaced by lightweight, inflated balloons, they lose all desires save for an insatiable thirst for joy. On one of the balloons that forms this Deviant’s head, a crudely drawn, emotionless face can be found—smeared and unsettling in its simplicity.
- Type:Deviant
-
Drops
- Customers either drop various scrap materials or Acid.
-
Location:
- Customers are low-ranking enemies commonly found throughout Nalcott.
The Customer is one of the more unsettling Once Human Deviants, twisted into a grotesque parody of consumer culture. Their heads have morphed into large, balloon-like orbs with pale, emotionless faces that seem permanently frozen in an eerie, vacant stare. These faces lack any recognizable emotion, reflecting a hollow detachment from the world — as if their desire for meaning or satisfaction has been utterly drained.

Despite their name, Customers are Once Human Deviants who no longer seek products or services—instead, they wander aimlessly, embodying the obsessive pursuit of fleeting joy or gratification that once defined them. They shuffle through ruined urban landscapes, often drawn to the remnants of stores or entertainment venues, as if compelled by a ghostly echo of their former consumer-driven lives.
Weaknesses
Customer
The Customer relies heavily on a charging melee assault, which leaves it exposed during wind-up and recovery. Its audio cues and stomping footsteps give away its approach, offering players a clear window to evade or counter. It lacks range and can’t adapt quickly to vertical or uneven terrain. Explosives and knockback effects can disrupt its rhythm. Use mobility and spacing to drain its health safely.
Their movements are slow and somewhat mechanical, lacking the urgency or aggression typical of many Once Human Deviants. However, their presence is deeply unsettling, reminding survivors of the emptiness left by a society addicted to materialism. Sometimes they emit faint, whispering sounds, like echoes of lost desires or half-remembered dreams.
Symbolically, the Once Human Customer represents the spiritual void beneath relentless consumerism — a hollow shell of a person, trapped in a cycle of seeking joy that can never be fulfilled. They are a tragic reminder of how the Stardust pandemic didn’t just mutate bodies, but also devoured the human soul.
Flare Bulbfly
Flare Bulbfly
The Flare Bulbfly is a striking, fiery-colored flying Deviant known for its bright, ember-like wings and quick movements. Unlike more passive Bulbflies, the Flare Bulbfly adds a dynamic element to the environment, often found near volcanic or heated areas. It’s prized for both its aesthetic and subtle buffs it provides when housed in your territory.
- Type:Deviant
-
Drops
- Territory Buffs: Increase the efficiency of fire-related crafting recipes or traps.
- Aesthetic Glow: Adds warm lighting effects to your base.
- Mood Boost: Enhances the morale of nearby Once Human Deviants, especially those linked to heat or fire.
-
Location:
- Scorching Bluffs: Rocky outcrops with natural heat vents.
- Ashen Fields: Areas with volcanic activity or recent fires.
- Molten Gorge: Near lava flows or hot springs.
- Charred Forest: Burnt woodland regions recovering from wildfires.
The Flare Bulbfly is a radiant and volatile flying Deviant, distinguished by its glowing, ember-like wings that flicker like small flames. Its body pulses with a warm, fiery light, casting flickering shadows on the surrounding environment, especially in darker or more desolate areas. This creature is often found near volcanic vents or scorched landscapes where residual heat fuels its unusual energy.

Despite its delicate and luminous appearance, the Flare Bulbfly is far from harmless. It carries an inherent volatility—when threatened or startled, it can release sudden bursts of heat or flames, igniting nearby flammable materials or causing localized explosions. This makes it a dangerous presence in tight spaces, especially near other Once Human Deviants or player structures.
Weaknesses
Flare Bulbfly
The Flare Bulbfly emits bursts of light and heat, but its attacks have noticeable charge-up times. It’s vulnerable while glowing, and a well-placed shot can interrupt its flare. It moves slowly and erratically, making it easy to track and snipe from a distance. Cooldown periods between flares offer great attack windows. Avoid clustered formations to negate its area burn effect.
When housed or tamed in a player’s base, the Flare Bulbfly—like some of the more volatile Once Human Deviants—offers unique benefits, such as increased heat resistance or a passive boost to energy regeneration, all tied to its fiery nature. Its presence brings warmth and illumination to the environment, but also carries the constant risk of combustion, adding both utility and danger to any settlement.
Symbolically, the Flare Bulbfly reflects the dual nature of Once Human Deviants shaped by Stardust—both destructive and life-giving. It’s a flicker of vitality in a broken world, a glowing reminder that even amid corruption, sparks of beauty and energy persist… though often with dangerous consequences.
Flashy Bulbfly
Flashy Bulbfly
The Flashy Bulbfly is a vibrant, flying Deviant recognized for its glowing wings and elusive flight patterns. While not hostile, these creatures are prized for their ability to enhance the environment around your territory, making them valuable for players focused on farming and base aesthetics.
- Type:Deviant
-
Drops
- Territory Aesthetic Boost: Their glow enhances your base ambiance.
- Mood Improvement: Raises morale of other Once Human Deviants housed nearby.
- Resource Attraction: Increases the spawn rate of certain luminescent or rare plants near your territory.
-
Location:
- Lumina Fields: Near bioluminescent plants and glowing groves.
- Glittering Glade: Around ponds and wetlands during dusk or nighttime.
- Radiant Ridge: Along cliffside paths and ridges with abundant light sources.
- Verdant Meadows: Open grassy fields with flowering plants.
The Flashy Bulbfly is a dazzling, mutated variant of the common Bulbfly, adorned with luminescent wings that shimmer in a kaleidoscope of colors, like a living light show. Its bright, flickering glow can disorient foes or attract other Once Human Deviants, making it both a dazzling spectacle and a subtle hazard.

This Bulbfly, a luminous example of Once Human Deviants, uses rapid wing beats to produce sudden flashes of blinding light, capable of stunning or disorienting anything caught nearby. Often seen fluttering around pockets of residual Stardust energy, it draws on this ambient power to fuel its unpredictable and dazzling displays.
Weaknesses
Flashy Bulbfly
Flashy Bulbfly dazzles enemies with sudden bursts of light, but it relies heavily on line-of-sight to blind effectively. Its brightness makes it easy to spot, even in darker zones. Tactical cover or well-timed movement renders its flashes ineffective. It is not very durable, so sustained fire can take it down quickly. Flash resistance gear makes encounters trivial.
Despite its radiant appearance, the Flashy Bulbfly is a deceptive and elusive Once Human Deviant. Its speed and control over light make it hard to track, especially in dim or chaotic environments. Players facing these creatures must remain vigilant, as a single burst of blinding energy can turn the tide of battle—or leave them completely exposed.
Symbolically, the Flashy Bulbfly reflects the deceptive allure found in many Once Human Deviants—mesmerizing and radiant on the surface, yet harboring the potential for chaos and harm beneath. It serves as a vivid reminder that in the world of Once Human, even the most beautiful things can be dangerously corrupted.
Gas Canister
Gas Canister
The Gas Canister is a crucial environmental object in Once Human, often found scattered across the world. While not a Deviant, these canisters can be used strategically—detonated to deal area damage to enemies or create tactical advantages during combat. Knowing where to find and how to use Gas Canisters effectively can turn the tide in tough encounters.
- Type:Deviant
-
Drops
- Explosive Damage: Canisters can be shot or detonated to cause explosions, damaging nearby enemies.
- Environmental Tactics: Use to create traps or clear groups of Once Human Deviants efficiently.
- Resource Recycling: Some crafting recipes require Gas Canister parts or fuel components found by scavenging around these objects.
-
Location:
- Dayton Wetlands: Around factory ruins and warehouses near mission zones.
- Broken Delta: Scattered among scrapyards and near vehicle wreckage.
- Chalk Peak: In mining camps and near gas storage facilities.
- Overgrown City: Along streets and inside abandoned garages.
The Gas Canister isn’t a Deviant in the traditional sense but rather an environmental hazard scattered throughout the ruined urban and industrial zones of Once Human. These rusted, dented metal containers hold volatile gases that have become dangerously unstable in the post-Stardust world.

When disturbed—by an explosion, gunfire, or a heavy blow—the canister erupts with a violent blast, unleashing a fiery explosion that deals significant area damage. As with many hazardous elements tied to Once Human Deviants, the detonation often releases a lingering cloud of toxic gas, causing damage-over-time and inflicting debilitating status effects like burning or poisoning on anyone unfortunate enough to remain within its radius.
Weaknesses
Gas Canister
The Gas Canister is volatile and prone to chain explosions when damaged, making it both a threat and a liability. Players can use its own gas clouds against it with incendiary or spark-based weapons. It lacks mobility and has poor awareness, often lingering in predictable patrol paths. With proper timing and ranged attacks, it can be eliminated before it gets close enough to pose real danger.
Players can strategically use Gas Canisters to their advantage by luring Once Human Deviants or hostile creatures near them before triggering an explosion. However, the risk is high, as the blast can also harm the player or allies if mismanaged.
Symbolically, the Gas Canister reflects the unstable legacy surrounding many Once Human Deviants—a reminder of humanity’s destructive past, now twisted into ever-present threats. These remnants of industrial ruin add a volatile edge to combat zones, reinforcing the idea that in a shattered world, even the environment itself can betray you without warning.
Gnawer
Gnawer
As the Stardust spreads further into its host, a Charred Maniac will evolve into a Gnawer. By this stage, most human features have been stripped away, with only the torso still resembling its former human form. Once its bodily tissue is entirely consumed by Stardust, the Gnawer is driven by an insatiable urge to hunt other physical forms, allowing its Stardust to feed. This relentless hunger is, in part, what inspired the name “Gnawer.”
- Type:Deviant
-
Drops
- Chance of dropping Acid
-
Location:
- Gnawers are low-ranking enemies, commonly found throughout Nalcott.
The Gnawer is a small but vicious Once Human Deviant, resembling a mangy, mutated rodent with sharp, yellowed teeth constantly gnashing. Its wiry frame and quick movements make it a relentless pest, capable of swarming in groups to overwhelm larger foes or players. Its fur is patchy, often slick with a sickly sheen, and its glowing red eyes betray a constant hunger for flesh and scrap.

Gnawers are scavenging Once Human Deviants that roam ruins and wastelands in search of anything edible or valuable. Though their bites are small, they carry a nasty infection that gradually weakens a player’s defenses. In packs, their relentless, coordinated attacks can grind down even the most heavily armored opponents through sheer persistence.
Weaknesses
Gnawer
Gnawer relies heavily on close-quarters attacks and has very little ranged threat. Its charging behavior makes it predictable and easy to bait into traps or obstacles. It also lacks armor and can be staggered with sustained gunfire or explosives. A smart player can kite it in open areas or eliminate it quickly before it closes the gap.
Though not particularly intelligent, Gnawers use their numbers and speed to their advantage, darting in and out of cover and distracting enemies while more dangerous Once Human Deviants close in. Players must remain cautious around them, as ignoring a Gnawer infestation can quickly lead to overwhelming odds.
Symbolically, the Gnawer embodies decay and survival stripped to their core—a creature forged by starvation and desperation, representing the relentless hunger that defines many Once Human Deviants and permeates the corrupted world.
Mayhem
Mayhem
The Mayhem is a low-ranking Deviant infected by Stardust, with a grotesque headless mouth. It moves quickly on all fours and lunges aggressively at its prey. This relentless hunter prowls Nalcott, testing players’ combat skills and reflexes.
- Type:Deviant
-
Drops
- Scrap materials (used for crafting and repairs)
- Acid (used for special crafting and combat advantages)
-
Location:
- Found throughout the Nalcott region
- Roams on all fours in ruined towns, forest edges, abandoned structures, and overgrown paths
- Prefers open yet cluttered areas for ambushes
Mayhem is a ferocious and chaotic Deviant, a hulking beast that embodies pure destruction and uncontrollable rage. Its massive, heavily scarred body is covered in jagged, mutated armor plates, and its eyes burn with a wild, frenzied light. This creature thrashes through the battlefield like a force of nature, crushing anything unfortunate enough to stand in its path.

Mayhem’s attacks are devastatingly powerful, capable of shattering defenses and sending shockwaves through the terrain. It uses brute strength and overwhelming aggression rather than subtlety, charging at foes with reckless abandon and unleashing wide, sweeping strikes that can knock back multiple enemies.
Weaknesses
Mayhem
Mayhem thrives in chaos but suffers in focused, coordinated engagements. Its erratic behavior can be distracting, but it leaves itself open to well-timed burst damage. Mayhem lacks solid defenses and is vulnerable to crowd control tools like snares or freeze effects. Players who keep their distance and maintain line-of-sight advantage can quickly neutralize this threat.
Despite its sheer physical power, Mayhem lacks strategic cunning; it is driven entirely by instinct and rage. Players facing this Once Human Deviant must focus on evasion and precise counterattacks, exploiting its predictable but relentless assault patterns.
Symbolically, Mayhem represents the raw, unbridled force of chaos unleashed by the Stardust pandemic — a living embodiment of destruction without purpose or control. Defeating it requires not only strength but calm precision in the face of overwhelming fury.
Morphic Crate
Morphic Crate
Morphic Crates are special loot containers that appear invisible until detected with your Cradle device. When revealed, they transform into hostile enemies that you must defeat to claim valuable rewards. These crates add a dynamic challenge as they actively engage the player once discovered.
- Type:Deviant
-
Drops
- Energy Links: Used for various upgrades and crafting.
- Stellar Planula: A currency for purchasing attachments in the Broken Delta Market.
- Stardust Source: A rare resource for advanced crafting.
-
Location:
- Dayton Wetlands: Near landmarks like Rotten Manor and shipping containers at North Shore Camp.
- Broken Delta: Around industrial areas such as the Sutherland Chemical Plant.
- Iron River: Along riverbanks and near structures like bridges.
- Chalk Peak: On hillsides, cliffs near Gaia Military Base, and around Fisherman’s Wharf.
Morphic Crates are the shimmering jackpots of the Onyx Tundra—like treasure chests with attitude. You’ll spot them glowing faintly in the frost, usually tucked away in abandoned bunkers, ruined labs, or guarded by mutated wildlife that really doesn’t want you to open them. These crates aren’t just eye candy—they’re your ticket to high-grade materials used in advanced weapon and armor crafting. Ignore them, and you’re basically leaving power on the table.

Biotite Clusters are nature’s way of saying, “Good luck, you’ll need it.” These jagged mineral growths pulse with strange energy and are usually found buried deep in corrupted zones or wedged between collapsed reactor cores. Mining one isn’t just a grab-and-go job—it’s a gamble. Radiation, Once Human Deviants, and the occasional environmental meltdown all want a piece of you. But crack one open, and you’ll be swimming in rare resources essential for modding gear and leveling up your arsenal. Treat them like ticking piñatas—high risk, high reward.
Weaknesses
Morphic Armor Crate
The Morphic Armor Crate may be sturdy, but it’s slow and lacks offensive capabilities. Its defense routines are predictable, allowing players to time their strikes between shield activations. EMP-type effects or shock rounds can disable its armor briefly. Coordination and patience make it easy to outmaneuver.
Crack open a Once Human Morphic Crate and you’re basically spinning a high-stakes loot wheel—minus the cheesy music and rigged odds. The usual suspects? Morphic Weapon Parts, Acid, and a generous sprinkle of Scrap Metal. These basics fuel most early-to-mid game upgrades, so even a “bad” crate still pushes your progress forward. It’s like opening a box of leftovers and finding your favorite snack still warm.

The Morphic Armor Crate is a mysterious supply container, fused with Stardust energy and pulsating with alien life. Unlike ordinary crates, this one seems almost sentient, its surface shimmering and subtly shifting like liquid metal. The crate’s energy hums softly, hinting at powerful protective gear contained within — armor crafted or enhanced by the corrupting influence of Stardust.

Players seeking to bolster their defenses prize these crates, as they contain rare, adaptive armor pieces that can resist or absorb damage from Once Human Deviant attacks and environmental hazards. The armor gained from these crates often comes with unique properties, such as elemental resistances or reactive shields, reflecting the morphic energy’s transformative nature.
Weaknesses
Morphic Armor Crate
While the Morphic Armor Crate offers strong defense, it lacks mobility and offensive power. It is easy to kite and outmaneuver in open areas. Its reliance on passive defense mechanisms makes it vulnerable to sustained, high-damage output from range. Use explosives or fire-based weapons to crack through its shell quickly and efficiently.
In the world of Once Human, these crates are coveted resources but also dangerous to approach. They may be guarded by hostile Once Human Deviants or rigged with traps, making the quest for their contents a risky but rewarding endeavor.
Symbolically, the Morphic Armor Crate represents the merging of human technology with alien mutation — a glimpse at how survival demands embracing change, even if it means relying on the very force that caused the apocalypse.
Morphic Weapon Crate
Morphic Weapon Crate
Morphic Weapon Crates are initially invisible and can only be detected using your Cradle device. As you approach, the Cradle flashes yellow, with the intensity increasing as you near the crate. Pressing the Q key reveals the crate, which then transforms into a hostile entity. Defeating it rewards you with valuable items such as Energy Links, Stellar Planula, and Stardust Source.

- Iron River: Spots include near the Mirage Monolith and along the riverbank under bridges.
- Chalk Peak: Crates are located on cliffs and hillsides, such as near the Gaia Military Base and southwest of Fisherman’s Wharf.
The Morphic Weapon Crate pulses with an eerie, alien energy that hints at the deadly tools contained within. Its surface is scarred and warped by the Stardust, making the crate look alive — as if the weapons inside are not merely crafted, but grown or evolved from the very corruption that devastated the world.

These crates contain rare, powerful weapons enhanced by morphic energy, granting unique abilities such as energy blasts, elemental damage, or rapid regeneration of ammunition. For survivors, finding a Morphic Weapon Crate means gaining access to armaments far beyond the usual scavenged gear, turning the tide against ever-evolving Once Human Deviants.
Weaknesses
Morphic Weapon Crate
The Morphic Weapon Crate delivers strong ranged attacks but suffers from a slow firing rate and limited mobility. It becomes significantly less dangerous once its weapon systems are disrupted or bypassed. Close-range attackers or fast-moving players can quickly flank it. Use EMP or shock-based effects to disable its offense and render it harmless.
Approaching these crates requires caution, as their unstable energy fields can sometimes trigger defense mechanisms or attract aggressive Once Human Deviants drawn to the power. They symbolize the dual-edged nature of Stardust technology: incredible power wrapped in unpredictable danger.
Symbolically, the Morphic Weapon Crate illustrates humanity’s desperate adaptation — harnessing alien mutation to fight fire with fire, even as the line between weapon and contagion blurs.

The stunning Onyx Tundra was the crown of the north, and Mousseville its most precious jewel-until the Starfall destroyed everything. These pastry chefs once used their hands to combine sugar, cream, and peaches into cakes, but now extend them towards the throats of the innocent.

Location:
- Mousseville Employee’s can be found in Mousse City.
The Mousseville Employee is a haunting remnant of a once-thriving corporate world, now twisted by Stardust’s corruption. Clad in tattered office attire stained with grime and strange growths, these Once Human Deviants shuffle aimlessly through the ruins of Mousseville’s office towers. Their faces are obscured by malformed visors or helmets fused with their flesh, distorting their human features into a mask of soulless servitude.

Despite their worn appearance, these employees are far from passive. They exhibit erratic, twitchy movements and attack with a mix of desperate claw swipes and blunt strikes using whatever office tools remain—broken monitors, sharp pens, or rusted chair parts. Their behavior suggests a lingering compulsion to “work,” a grim echo of their previous lives, even as they have become mindless agents of chaos.
Weaknesses
Mousseville Employee
Mousseville Employees are erratic and relatively weak in isolation. Their strength comes from group coordination, but alone they can be overwhelmed with sustained damage. They lack heavy armor and are vulnerable to area-of-effect attacks that break their defensive patterns. Target them early to prevent them from rallying stronger support.
Symbolically, the Mousseville Employee embodies the dehumanizing effects of corporate monotony, warped into something monstrous by the Stardust’s invasive influence. They serve as a chilling metaphor for lost identity and the consumption of individuality by relentless systems.
Novice Employee
Novice Employee
Employees are responsible for the daily operation of Wish Land. They dedicate themselves to their work out of love, with their only desire being to bring others joy. When a Customer becomes a Wish Land employee, they are outfitted in a stuffed bear costume, and their latex balloons are replaced with foil animal-face balloons. The Novice Employee Deviant is identifiable by its single balloon, marking it as a newcomer to the workforce.
- Type:Deviant
-
Drops
- Novice Employees either drop various scrap materials or Acid.
-
Location:
- Novice Employees are low-ranking enemies commonly found in the The Way of Winter Scenario.
The Novice Employee is a less corrupted, more desperate Once Human Deviant still clinging to fragments of their former identity. Dressed in worn and disheveled office wear, they bear faint traces of humanity—an occasional flicker of hesitation or recognition in their eyes—though their bodies are twisted by Stardust mutation. Their movements are jittery and uncertain, as if caught between willful servitude and rising chaos.

These Once Human Deviants often wield makeshift weapons—shattered office supplies or crude tools—using them with a frantic mix of aggression and fear. Though weaker and less coordinated than more “seasoned” Once Human Deviants, their numbers can overwhelm players if underestimated.
Weaknesses
Novice Employee
Novice Employees lack combat experience, making their attack patterns predictable and slow to adapt. Their defenses are minimal, and they often panic when overwhelmed, creating easy opportunities for follow-up attacks. Fast, aggressive tactics can exploit their hesitations before they regroup or escalate into more dangerous forms.
The Novice Employee symbolizes the early stages of Stardust’s corruption: caught in the painful transition from human to monster. They represent the fragile balance between retaining humanity and succumbing fully to the alien contagion.
Researcher
Researcher
As of now, far more of them have been sighted than members of the lost expedition team. There must be something hiding deep in the sea. After spending an unimaginable amount of time submerged in the frigid, Stardust-infused ocean before finally reaching land, the Researcher’s exposed skin has become encrusted with immutable Living Ice. This transformation grotesquely distorts their bodies, leaving them as eerie, substandard replicas of the original expedition team.
- Type: Deviant
-
Drops
- Researchers either drop various scrap materials or Acid.
-
Location:
- Researchers are low-ranking enemies commonly found in the The Way of Winter Scenario.
The Researcher is a twisted remnant of humanity’s quest for knowledge, corrupted by Stardust into a disturbing figure clad in tattered lab coats fused with alien growths. Its eyes, once filled with curiosity, now glow with cold, calculating malice, scanning the environment with unnatural precision.

Equipped with mutated limbs that function like surgical tools, the Researcher experiments on both living creatures and the fallen, inflicting painful and bizarre mutations. Its attacks are a mix of precise strikes and unsettling bio-electric bursts, capable of weakening or disrupting a player’s abilities.
Weaknesses
Researcher
Researchers prioritize analysis and technology over physical defense, making them especially vulnerable in direct confrontations. Their reliance on gadgets and experimental tools can backfire if disrupted. Burst damage and fast engagements prevent them from activating their tricks or repositioning safely.
This Deviant often supports other corrupted beings by enhancing their mutations or deploying traps that manipulate the battlefield. The Researcher embodies the dark side of humanity’s scientific obsession — a chilling reminder that the pursuit of knowledge, when twisted by alien corruption, can become a weapon of horror.
Searchlight
Searchlight
Searchlight is a creepy, bipedal deviant in Once Human that resembles a walking spotlight with legs—think sentient streetlamp with a vengeance. It roams dark areas scanning for movement with its blinding beam, locking onto anything it deems a threat. Once spotted, you’ll either be calling for backup or running for your life. It’s not just for show either—Searchlight can alert nearby Once Human deviants, making it both a scout and a siren of doom. Stealth or swift takedowns are your best bet if you want to survive its spotlight sweep.
- Type:Deviant
-
Drops
- Mechanical Components – Useful for crafting advanced tech and weapon mods
- Energy Conduits – Mid-tier crafting material used in power-based upgrades
- Deviant Data Fragments – Valuable for research and unlocking tech trees
-
Location:
- Searchlights are most commonly found in nighttime zones, abandoned military checkpoints, and urban ruins where Once Human Deviants patrol in coordinated groups. You’ll often encounter them in Ruined City sectors or high-alert areas like the Twilight Outposts. They’re especially active at night, using their search beams to scan for movement—so bring stealth gear or be ready for a fight.
The Searchlight is a haunting, mechanical Deviant fused with remnants of human technology and corrupted by Stardust energy. It takes the form of a towering, tripod-mounted spotlight, its lens glowing with an eerie, pulsating light that sweeps methodically across the ruins. Despite lacking organic features, it seems almost sentient, its movements deliberate and unsettling.

Its primary function is to illuminate and expose any intruders or creatures hiding in the shadows. When the beam catches a player or Once Human Deviant, it can trigger alarms or call nearby hostile creatures to the area. The Searchlight’s piercing gaze makes stealth and careful movement essential, as it can quickly turn a safe approach into a dangerous confrontation.
Weaknesses
Searchlight
The Searchlight relies heavily on vision and tracking, which can be circumvented with fast, erratic movement or smoke-based distractions. Its beam is strong but narrowly focused, leaving it open to flank attacks. If caught off-guard, it lacks the defenses to recover or retreat effectively.
Symbolically, the Searchlight represents the oppressive surveillance and unrelenting scrutiny in a world where nothing remains hidden. It embodies the tension between light and darkness, safety and danger, order and chaos.
Senior Employee
Senior Employee
All the sky above Wish Land is their stage, and they give visitors unexpected surprises by dropping colors from above. When a Novice Employee is promoted to a Senior Employee, they gain additional balloons, allowing them to move freely through the air. In Once Human, the Senior Employee is a rare Deviant that can be secured through specific in-game activities. While detailed information about this Deviant is limited, players have reported encountering it in certain locations and under particular conditions.
- Type:Deviant
-
Drops
- Senior Employees either drop various scrap materials or Acid.
- Mechanical Components: Useful for crafting advanced tech and weapon modifications.
- Energy Conduits: Mid-tier crafting materials used in power-based upgrades.
-
Location:
- Senior Employees are low-ranking enemies commonly found in the The Way of Winter Scenario.
- White Cliff: In the garage, turn right to find a Deviant cage.
- Blackfell: Near the center, easy to spot on the roof.
- Rippleby in Iron River: Left of the entrance, near the main path
- Greywater Camp: On the roof, accessible after teleporting.
The Senior Employee is a more advanced and hardened Deviant among the corrupted workforce. Dressed in faded, torn business attire marked by stains and alien growths, this Deviant carries an air of authority despite its monstrous transformation. Its face is partially obscured by a cracked visor fused into its skull, with glowing eyes that pierce through the gloom.

Unlike lower-tier employees, the Senior Employee fights with calculated strikes, wielding heavier, improvised weapons such as rusted briefcases or twisted metal pipes. It commands lesser Once Human Deviants with guttural growls, coordinating attacks to overwhelm intruders or defenders.
Weaknesses
Senior Employee
The Senior Employee is slow to react and often overly reliant on protocol-based behavior, which can be exploited with unpredictable tactics. Its attacks are more disciplined but lack the flexibility of lower-ranked enemies. With enough pressure or rapid repositioning, it can be overwhelmed before it executes its full pattern.
Symbolically, the Senior Employee represents the corrupted hierarchy of the old corporate world—twisted leadership that persists even after humanity’s collapse, enforcing control through fear and violence in a broken society.
Spiderling
Spiderling
The Spiderling is a fast and nimble Deviant that skitters across walls and ceilings, often attacking in swarms. Though individually weak, their agility and numbers make them a persistent threat, especially in dark, enclosed areas. Watch your step and keep moving to avoid getting trapped by their webbing.
- Type: Deviant
-
Drops
- Chitin Fragments
- Spider Silk Threads
- Venom Sac (rare)
- Sticky Resin (used for crafting traps)
-
Location:
- Commonly found in the damp caves and tunnels beneath Wish Land.
- Frequently appears in the Shadow Hollow and the Forgotten Sewers.
- Often encountered in groups near old mining shafts and abandoned underground facilities.
The Spiderling is a small, fast-moving Once Human Deviant that resembles a grotesque fusion of human and arachnid features. Its body is covered in chitinous plating, with spindly legs that allow it to scuttle swiftly across walls, ceilings, and floors. Despite its size, it has razor-sharp fangs and claws that it uses to latch onto prey, injecting a paralytic venom.

Spiderlings often swarm in groups, using their agility and numbers to overwhelm foes before larger Once Human Deviants arrive. Their eerie, chittering sounds echo through dark corridors, making them a constant threat in confined spaces. They can climb nearly any surface, making ambush tactics a common part of their behavior.
Weaknesses
Spiderling
Spiderlings rely on swarming tactics, but individually they are extremely fragile and go down in just a few hits. Their low HP and predictable scuttling behavior make them easy to clear with area damage or rapid-fire weapons. If caught alone or funneled through narrow terrain, they pose little threat.
Symbolically, the Spiderling represents the creeping and invasive nature of the Stardust corruption — a small but relentless predator that spreads terror and infection wherever it goes.
Stardust Maniac
Stardust Maniac
The Maniac is the petri dish in which the ‘Sky Dome Mother’ cultivates her offspring. As the ‘seed,’ or the ‘life’ of the Memetic infection grows deeper, the Maniac loses weight rapidly due to abnormal absorption of biomass. The Stardust Maniac Deviant exhibits mutations similar to the Charred Maniac: withered muscles, festering skin, weakened limbs, and cloudy eyes. However, a distinguishing feature is the grotesque infection bulging from the top of its skull.
- Type: Deviant
-
Drops
- Stardust Maniacs may drop various scrap materials or Acid.
-
Location:
- Stardust Maniacs are low-ranking enemies commonly found throughout Nalcott.
The Stardust Maniac is a terrifying Deviant, consumed utterly by the corrupting influence of the Stardust. Its body is a chaotic mass of glowing crystals, twisted flesh, and jagged spikes that pulse with unstable energy. Wild, frenzied eyes dart beneath a fractured skull, and its movements are erratic and unpredictable.

This Deviant attacks with reckless abandon, using a combination of brutal melee strikes and explosive bursts of Stardust energy that can cause area-wide devastation. Its sheer volatility makes it dangerous to approach, as it can explode violently when injured or cornered.
Weaknesses
Stardust Maniac
The Stardust Maniac is dangerous up close but lacks solid ranged options, making it easy to kite with firearms or abilities. Its glowing frenzy state is telegraphed and can be avoided with good timing and positioning. Mobility-based tactics or long-range damage can keep it in check before it becomes a serious threat.
Symbolically, the Stardust Maniac represents the ultimate loss of humanity to the alien corruption—pure chaos incarnate, driven by madness and destruction with no regard for anything but itself.
Stinger Bulbfly
Stinger Bulbfly
The Stinger Bulbfly is a swift and aggressive Deviant resembling a giant bioluminescent insect. It uses its sharp stinger to deliver venomous attacks and can quickly dart around to evade counterattacks. Often found near glowing flora, the Bulbfly lights up dark areas while posing a significant threat with its relentless stings.
- Type: Deviant
-
Drops
- Bulbfly Wings
- Venom Gland
- Bioluminescent Fluid (rare)
- Stinger Core (used for crafting poisons and traps)
-
Location:
- Found mostly in luminous forest areas and near bioluminescent plants in Wish Land.
- Commonly encountered in the Glowgrove and Luminescent Hollow zones.
- Often active during twilight and nighttime, making it a challenging opponent in low visibility.
The Stinger Bulbfly is a fierce, aggressive variant of the Bulbfly species, distinguished by its sharp, needle-like tail capable of delivering a venomous sting. Its wings shimmer with a sickly greenish hue, and its body is armored with hardened, segmented plates that protect it in combat.

This Once Human Deviants is territorial and quick to attack, darting swiftly at enemies and using its stinger to inject a potent neurotoxin that causes paralysis or disorientation. Its aggressive behavior often draws the attention of other Once Human Deviants, making encounters especially dangerous.
Weaknesses
Stinger Bulbfly
The Stinger Bulbfly relies heavily on its flight and rapid darting to avoid attacks, but it has very low durability. It’s especially vulnerable to area-of-effect abilities or weapons that track or splash. A good marksman can also swat it down quickly before it has time to do serious damage.
Players facing the Stinger Bulbfly must stay alert to its sudden strikes and venomous threat. Despite its smaller size compared to other Once Human Deviants, its sting can cripple opponents, turning a minor nuisance into a deadly hazard.
Symbolically, the Stinger Bulbfly embodies the hidden dangers lurking beneath beauty — a reminder that the Stardust mutation often masks lethal threats in seemingly delicate forms.
Swarm
Swarm
The Swarm is a chaotic mass of small, aggressive Once Human Deviants that attack relentlessly in groups. Individually weak but dangerous in numbers, they overwhelm opponents by sheer volume and speed. Swarms are often found in dark, abandoned areas where they can multiply rapidly, making quick and decisive action critical to survival.
- Type: Deviant
-
Drops
- Swarm Tissue
- Deviant Claws
- Corrosive Saliva (rare)
- Swarm Core (used in crafting defensive gear)
-
Location:
- Commonly found in underground tunnels and abandoned ruins.
- Often appears near corrupted zones and dark caves within Wish Land.
- Frequently encountered in large groups, especially after disturbances or attacks.
The Swarm is a chaotic mass of small, fast-moving Once Human Deviants that overwhelm targets through sheer numbers. Composed of countless tiny, insect-like creatures, the swarm moves as a single, writhing entity, capable of infiltrating tight spaces and attacking from multiple angles at once.

This collective acts with unsettling coordination, quickly stripping flesh or defenses from larger foes before retreating into shadows. The buzzing, scratching sounds of the swarm create a constant atmosphere of dread, signaling imminent danger.
Weaknesses
Swarm
The Swarm overwhelms players through sheer numbers, but each individual unit is fragile and easy to kill. Area damage weapons like flamethrowers or grenades can clear them out rapidly. They’re also easy to kite and lead into environmental hazards for quick disposal.
Players facing a Swarm must rely on area-of-effect attacks or crowd control to avoid being overwhelmed, as individual strikes against the swarm are largely ineffective.
Symbolically, the Swarm represents the overwhelming and invasive force of Stardust corruption — an unstoppable tide that consumes everything in its path through relentless persistence.
Watcher
Watcher
The Watcher is a creepy, sentinel-like Deviant with a giant spotlight for a head. Often perched in elevated areas or roaming checkpoints, it scans the dark with its blinding beam, alerting nearby enemies if it spots you. It’s not the toughest fight, but stealth or ranged attacks work best—unless you enjoy getting swarmed.
- Type: Deviant
-
Drops
- Mechanical Parts
- Optical Lens
- Spotlight Core (rare)
- Crystallized Nerva (uncommon drop used for crafting/upgrades)
-
Location:
- Commonly found patrolling around abandoned military zones, outposts, and road checkpoints, especially during nighttime.
- Most frequently encountered in the Graywater Zone and near radio towers or surveillance sites.
The Watcher is a mysterious and unsettling Once Human Deviants, resembling a tall, slender humanoid draped in tattered robes and adorned with glowing, all-seeing eyes scattered across its body. Its elongated limbs move with eerie grace, and it emits a low, unsettling hum that unsettles those nearby.

This creature is believed to serve as a scout or sentry for more powerful Once Human Deviants, silently observing and reporting intruders or prey. Its multiple eyes grant it nearly unparalleled vision, able to detect movement and heat signatures from afar, making stealth near the Watcher a near-impossible task.
Weaknesses
Watcher
Watchers rely heavily on their vision-based mechanics and detection beams. They’re vulnerable when flanked or approached from blind spots. Bright light sources or smokescreens can help break line-of-sight, giving players a safe window to engage. Disabling them early can prevent alert chains.
Though it rarely attacks directly, the Watcher can unleash psychic or energy-based attacks to disorient or incapacitate foes, calling other Once Human Deviants to its location when threatened.
Symbolically, the Watcher represents the relentless scrutiny that defines many Once Human Deviants—a silent guardian of the corrupted world’s mutated order, ever-watchful and unforgiving.
