☣️ Human Extinction Virus (HEV) – Overview
This virus is a hyper-aggressive, synthetic-engineered bioweapon—likely the result of failed bioengineering tied to the Tubby Custard development labs. It was designed (intentionally or not) to interface with human DNA, making it species-specific, and ensuring that it would never affect tubbies... only humans.
It is airborne, surface-transmissible, and even contaminates water supplies, which is why it spread so rapidly across the globe.
🧬 Symptom Progression in Humans (HEV Infection Stages)Stage 1 – Incubation (0–6 hours post-exposure)
Silent but deadly – The virus has no immediate symptoms, making it highly dangerous.
Takes root in soft tissue – Especially in the lungs, eyes, brainstem, and sinus cavities.
Infected individuals feel fine, may even have elevated energy levels and mental clarity for a brief period (false positive).
Stage 2 – System Hijack (6–12 hours)
Fever spikes to 41°C (105.8°F) – Often fatal on its own if untreated.
Severe photophobia – Eyes become red, veiny, and light causes intense pain.
Neurological disruptions – Visual hallucinations, audio distortions, minor seizures.
Skin discoloration – Begins around neck, chest, and spine; turns ashen-gray, then greenish-purple as veins swell visibly.
Stage 3 – Collapse and Internal Breakdown (12–20 hours)
Organ failure begins, starting with the liver, then lungs and kidneys.
Violent vomiting – Often blackish-red due to internal hemorrhaging.
Bleeding from orifices – Eyes, nose, mouth, ears.
Muscles begin to contract and twist randomly—nerve misfiring leads to spasms or locked limbs.
Victim loses ability to speak clearly—language breaks down to incoherent screaming or whispering gibberish.
Stage 4 – Death and Tissue Liquefaction (20–30 hours)
Full nervous system collapse.
Brain matter begins to dissolve, often oozing from eyes or nose in final moments.
Heart stops, but body often twitches for hours post-mortem.
Skin peels, leaving an oily, dark biofilm—the body melts into itself.
Bodies cannot be buried or burned safely—the virus survives even high-heat cremation, which is why entire zones were locked down or firebombed.
🧠 Psychological Symptoms
While physical degradation is intense, the virus also attacks the frontal lobe. Mental symptoms can include:
Paranoia and delusions
Belief of being stalked, watched, or hunted
Sudden aggression toward others (final panic phase)
"Sound hallucinations" – Believing machinery, whispers, or crying is nearby even in silence
Breakdown of language (like speaking in reverse or foreign tongues the victim never knew)
☣️ Additional Facts for Lore:
The virus mutates differently in people with certain genetics—but all outcomes are fatal.
There is no cure.
Wearing a protective suit delays infection but does not prevent it—airborne nano-molecules can bypass typical filters over time.
Teletubby biology is completely immune, which is why society shifted entirely toward that species for survival.
🧬 How UltSans Could Get Infected with the Human Virus
Despite his origins, UltSans has a partially human biological structure. While enhanced by void magic and composed of mixed monster-human components, he has a functioning organic body, which includes nerves, lungs, circulatory pathways, and a semi-living skin surface. That alone makes him biologically viable for infection by the human-targeted virus.
🧪 Exposure Methods for UltSans
1. Airborne Transmission
The virus is suspended in the air, especially in high-contamination zones like tunnels, dead villages, or ruins of old research labs.
Inhalation through nose or mouth would draw the viral particles into his lung membranes, which contain absorbent tissue biologically similar to human alveoli.
Since UltSans does breathe to regulate his internal systems, especially for soul-balance and pressure control, breathing contaminated air equals direct exposure.
2. Direct Contact with Infected Fluids or Tissues
Any contact with infected blood, saliva, or biological waste (like remains or internal matter from infected creatures or corpses) is dangerous.
If UltSans touches these fluids with bare hands or if they splash on his face, especially around the eyes, nostrils, mouth, or open wounds, he can be infected immediately.
His skin, though toughened, is sensitive and biologically absorbent, which allows even trace amounts to enter the system.
3. Surface Contact through Damaged Skin
If UltSans is scratched, cut, or burned, and he touches infected surfaces or creatures afterward, the virus can pass into his body through exposed tissue.
Infected soil, decayed walls, and infected corpses may hold virus particles dormant, and physical contact with them while wounded is high risk.
4. Oral Transmission
If UltSans eats or drinks anything contaminated—even unintentionally (e.g., using old water sources, scavenged food, or absorbing soul fragments from infected)—he's at risk.
His digestive system still processes and converts energy, meaning viruses can enter via the stomach lining and spread to vital systems.
5. Eye and Ear Exposure
Viral particles can enter through the moist, unprotected surfaces of the eyes or inner ear canals.
If an infected coughs or sprays fluid nearby, or if blood splatters during a fight, this is a very fast method of infection.
Even wiping his eyes or ears with an infected glove or cloth could expose him.
6. Soul Fluid Contamination
While his soul is void-based, the fluid circulating through his system mimics biological blood and keeps his body operational.
If the virus infects this inner fluid directly—through a deep wound or injection—it would spread rapidly through his body like bloodstream infection.
This is especially dangerous if he interacts with infected soul remnants or absorbs any aura/magic from corrupted beings.
🧪 Signs That UltSans Is Infected
Once the virus begins to affect his body, the following physical and biological signs may occur:
Internal Temperature Drop
His body begins to go cold as the virus shuts down his regenerative cell functions.
Discoloration of Skin and Bones
Pale tones go gray, veins blacken under the surface, slight rotting odor appears.
Erratic Breathing and Vocal Glitches
Short, broken breathing. Voice may glitch or lag due to respiratory and vocal damage.
Severe Muscle Cramps and Twitching
Limbs jerk involuntarily as infected nerves misfire.
Blurred Vision, Eye Bleeding
Due to blood vessel rupture in the retinas from internal fluid overload.
Loss of Control
Near the final stage, he may hallucinate, freeze in place, or convulse.
🩸 Early Stage (Incubation – Hours to 1 Day)
Symptoms begin subtly as the virus begins replication within the mucosal tissues or bloodstream.
Fatigue and Lethargy
Noticeable drop in energy, slower physical movement, weakened muscle tension.
Headache and Sinus Pressure
Viral presence in cranial cavities causes inflammation and dull, spreading pain.
Fever and Chills
Immune system attempts to respond with elevated body temperature. Chills follow due to destabilized thermoregulation.
Mild Cough or Throat Irritation
Begins if infection was airborne or entered via the mouth/nose. Viral colonies irritate respiratory linings.
Eye Redness and Dryness
The virus attacks mucosal membranes; bloodshot appearance and dryness begin early.
🧠 Intermediate Stage (Systemic Spread – 1 to 2 Days Post-Infection)
At this point, the virus is circulating through bodily fluids and beginning neurological impact.
Disorientation or Lightheadedness
Reduced oxygen transport, impaired neuron signaling. Balance and awareness become unstable.
Muscle Aches and Joint Pain
Inflammation of muscle tissue due to cellular apoptosis and immune reaction.
Vomiting or Nausea
Infection of the stomach lining or central nervous system triggers nausea and expulsion reflex.
Excessive Sweating or Cold Skin
Autonomic system loses stability. The body attempts to cool down even when cold.
Loss of Appetite and Thirst Dysregulation
Infection in the hypothalamus or gastrointestinal system suppresses basic survival signals.
🔬 Late Stage (Organ/System Failure – 2 to 4 Days)
Severe signs of infection, critical tissue damage, and failing biological functions.
Jaundice or Skin Discoloration
Yellowish, pale, or gray skin tone emerges due to liver stress and blood toxicity.
Severe Coughing with Blood
Pulmonary tissue begins to rupture or break down from infection. Hemorrhaging starts.
Tremors or Full-Body Twitching
Nervous system deteriorates. Signals misfire, causing uncontrollable muscle spasms.
Dilated Pupils and Visual Distortion
Pressure in the brain and optic nerves causes light sensitivity, vision blur, or tunnel vision.
Open Sores or Skin Peeling
Epidermal cells start dying rapidly. Lesions appear across the arms, neck, and mouth.
🧠 Terminal Stage (Near Death – Final Hours)
Multi-organ failure, irreversible neurological shutdown, death imminent.
Seizures or Convulsions
Severe inflammation in the brain leads to uncontrolled electrical activity and full-body seizures.
Labored Breathing or Gurgling Sounds
Lungs filled with fluid or blood. Airway constriction causes wheezing or choking.
Coma or Unresponsiveness
Brain activity slows. Body enters shutdown phase. No response to stimuli.
Internal Bleeding and Organ Failure
Blackened veins may appear visually as blood coagulates. Organs rupture internally.
Cardiac Arrest
Irregular heartbeat, then sudden stop. Complete biological death follows.
