Superbiological Entity

A superbiological entity is any creature, object, or being with unrecognized (or unexplained and possibly dangerous) powers that could be explained as supernatural. Classified by Nero biologists, superbiological creatures are considered too dangerous to be in public, and all are to be contained in containment facilities. While not all are dangerous, it is believed that to bring said entities to public light could lead to catastrophic events, as entities can be extremely harmless, or so powerful and benevolent as to destroy reality as we know.

Nero Classifications

Nero has set up certain ways to classify superbiological entities, which are used to identify things such as the dangers of engaging one, the behaviors of entities, and how to properly contain one.

Naming Conventions

Entities are named using the following format: CLASS-CODE-SUFFIX. The class is a three-character abbreviation of the type of entity, such as Abnormal (ABN) or Object (OBJ), listed below.

The code is a unique set of three digits corresponding to that entity. In 1973, after Nero realized three digits wasn't going to be enough, they also added another character to the beginning of the code. The characters used come from the English and Greek alphabet, with the Hebrew character "ℵ" being used for entities related to the [REDACTED]. The original codes using only three digits still remained, but any entity classified after #999 of a category had the letter "A" before the code.

The suffix only comes into play when an entity has other sub-entities associated with it. For example, ABN-071 produces a harmful bacteria known as ABN-071-A. The suffix can be a letter, a number, or the name of a Greek letter spelled out in all caps (ALPHA, BETA, UPSILON, etc.) There is no formal specification for what type of suffix should be used in what situation.

Entity Type

• Abnormal-Class Entity. Shortened to "ABN" when naming entities, Abnormal-Class entities are physical creatures who's bodies are utterly alien to anything considered "textbook". In other words, any creature who's body is considered "abnormal".
• Biotic-Class Entity. Shortened to "BIO" when naming entities, Biotic-Class entities resemble common species of flora and fauna. Examples of such entities could be a cat that can teleport, or a whale that can turn invisible.
• Contagion-Class Entity. Shortened to "CON" when naming entities, Contagion-Class entities are anomalous pathogens, parasites, or other forms of infections.
• Event-Class Entity. Shortened to "EVE" when naming entities, Event-Class entities are once-observed or reoccurring events with unexplained anomalous effects.
• Human-Class Entity. Shortened to "HMN" when naming entities, Human-Class entities are humans that were either born or somehow formed superbiological powers, whether they are as mild as a human with gills or as absurd as a human with machine guns for arms. However, a Human-Class entity must have a sort of human sentience to be accepted into this category.
• Information-Class Entity. Shortened to "INF" when naming entities, Information-Class entities are memetic hazards. An anomalous phrase or thought that is dangerous to think could be classified as such entities.
• Location-Class Entity. Shortened to "LCT" when naming entities Location-Class entities are buildings or towns, or other places with anomalous properties. Such entities could be a building that slows down time for you when you enter, or a copy of a city built underneath the original.
• Object-Class Entity. Shortened to "OBJ" when naming entities, Object-Class entities are non-sentient objects that appear to have a strange capability (or effect) that does not abide by the known laws of the world. Such entities could be a water bottle that refills itself automatically, or a mask that attaches to your skin when you put it on.
• Planar-Class Entity. Shortened to "PLN" when naming entities, Planar-Class entities are essentially alternate dimensions and universes. While it is so far forbidden to enter said portals, many claim that whatever's on the other side could be so alien to humans that we simply couldn't exist there; though no one is sure.
• Spectral-Class Entity. Shortened to "SPC" when naming entities, Spectral-Class entities are non-physical being often mistaken for ghosts or spirits. In reality, most accounts of spirits are just Spectral-Class entities taking on the form of a deceased person. To be accepted into this category, an entity must be non-physical and be able to change form in one way or another.
• Technology-Class Entity. Shortened to "TCH" when naming entities, Technology-Class entities are machines and devices with strange properties. For the most part, entities in this category are powered by electricity, though there are a few exceptions. Computer programs and viruses with anomalous effects are also included in this category.

Danger Level

An entity's danger level explains how hostile, and capable in it's abilities, an entity is.

Danger Level	Description
Danger Level 0	Incapable of harm: completely safe.
Danger Level 1	Near-harmless: safe, but still worthy of a threat level.
Danger Level 2	Relatively harmless unless provoked: Even in a dangerous state, the entity is not hard to avoid.
Danger Level 3	Passive: entity presents a threat only when provoked, but is capable of substantial harm.
Danger Level 4	Low-level threat: entity is dangerous, but can be dispatched of easily.
Danger Level 5	Hazardous: entity should always be treated as such.
Danger Level 6	High-level threat: entity is extremely hazardous.
Danger Level 7	Top-priority threat: entity poses a critical threat if uncontained, and should be treated as a top-priority in case of a containment breach.
Danger Level 8	Hyper-lethal: entity is extremely hazardous, and presents a high-level threat, even when contained.
Danger Level 9	Extreme hazard: entity is considered a critical hazard, and is capable of near-irreversible damage if released.
Danger Level 10	Maximum containable threat level: entity poses a threat to society, the world, or even humanity as a whole.
Danger Level YX	Reality-warping: entity can alter the fabric of time and space at will.
Danger Level XX	Impossible to research/contain: entity can only be described as “eldritch”, and cannot be reasoned with or directly contained. In other words, knowing of its existence is all we can do.

Security Grade

An entity's security grade is made to tell how the entity should be approached if ever encountered and how to properly contain the creature.

• Security Grade Atlas. Entity does not require any special containment procedures, and can often be contained in a basic cell.
• Security Grade Banner. Entity is either too fragile or too valuable to be maimed or killed, meaning special precautions should be taken to capture and transport.
• Security Grade Carbon. Entity is not bothered by containment, and requires very little force to secure.
• Security Grade Data. Entity should be presented with full-fledged violence, whether to maim or to kill.
• Security Grade Eclipse. Entity is of biohazardous origin and possibly contaminated areas should be enclosed and blocked off. Entity should be captured due to risk of contamination.
• Security Grade Fox. Entity’s containment protocols are very complex, and require a team of high-ranking scientists to oversee it.
• Security Grade Ghost. Entity has multiple functioning elements, and uses it to overwhelm others.
• Security Grade Hybrid. Entity is either highly adaptable to it’s environment or is considered “invincible”, requiring immediate capture. Force is not required in most cases.
• Security Grade Ion. Entity requires no force whatsoever to be captured, as it is either non-sentient or not threatened by humans.
• Security Grade Jolt. Entity cannot be contained by physical means, and must be secured outside of a facility.
• Security Grade Kingpin. Entity is either extremely intelligent, or learns from it’s mistakes.
• Security Grade Lone. Entity is capable of destruction on a mass scale, and seems to exist for that sole purpose.
• Security Grade Mark. Entity utilizes wormholes, alternate dimensions, and the alteration of reality.
• Security Grade Neptune. Entity is currently being safeguarded by other humans. Violence is only to be enforced if given orders to engage.
• Security Grade Operate. Entity has been identified by the public eye, and necessary actions must be taken to cover it as a hoax.
• Security Grade Pawn. Entity has infiltrated a NERO facility and may be hiding among the agents inside. Full and complete purge may be necessary.
• Security Grade Quad. Entity is considered infectious (more so than a security grade eclipse) and may have infected a number of people outside it’s containment cell.
• Security Grade Resistor. Entity is is being used for the benefit of Nero or humanity, and is considered an ally of Nero.
• Security Grade Stalker. Entity is must be left alone in a containment facility made only for itself. No human contact allowed ever.
• Security Grade Temper. Entity affects those that know of its existence, experience it, or are otherwise exposed to its information.
• Security Grade Unit. Entity is related  to a recurring event of anomalous origin.
• Security Grade Viper. Entity has not been researched to a full extent, due to possible and unknown danger. It is highly advised that no one interact with it without direct orders from the Chief of Containment Protocols.
• Security Grade Wolf. Entity cannot be killed, or will come back if it is.
• Security Grade Xeno. Entity does not abide by the laws of physics.
• Security Grade Young. Entity is contained within itself, and must be protected in order to prevent containment breach.
• Security Grade Zodiac. Entity cannot be comprehended or experienced by normal means.

Containment Restriction

An entity's containment restriction determines which Nero personnel are allowed to interact with it, or know of its existence.

• White. Common knowledge: the specials on today’s lunch menu.
• Blue. An entity that you could probably contain in a plastic bucket.
• Green. An entity that an unauthorized staff member may be killed for seeing.
• Yellow. A secret test to see who would win between a bus-sized iguana and a jello monster.
• Orange. An entity that you thought was that leaky pipe for the past 4 years.
• Red. An entity that has broken containment and is hiding in your house. Hey, I don’t remember hanging that painting…
• Purple. A secret experiment. One that no one knows about because it’s secret.
• Black. An entity that eats you over and over again in every different reality conceivable.
• Silver. Cthulhu… or Ktulu… or Kathulu…
• Gold. We don’t know. They didn’t tell us.

Trivia

• There are many entities that do not fit in any of the listed security grades, though they are considered "independent entities".
