Purpose	Metahuman Threat Assessment and Emergency Response Coordination
Current Revision	Revision 6.3
Status	Active

“When an MTAS alert is issued, remember: preparedness saves lives. Stay informed. Stay calm. Follow authorized emergency instructions.”
— PHASE II Emergency Advisory Bureau

Since the emergence of public superhuman activity during the Golden Age, governments, emergency responders, and metahuman organizations have faced a difficult problem: How does one rapidly assess threats beyond conventional human experience?

The answer is the Metahuman Threat Assessment System, commonly known as MTAS.

Originally developed jointly by PHASE II analysts, military planners, emergency management agencies, and metahuman specialists, the MTAS system provides a standardized method of classifying enhanced individuals, anomalous phenomena, alien incursions, technological hazards, and other extraordinary threats.

The MTAS system is now recognized internationally and is used by:

• PHASE II
• Military organizations
• Emergency services
• International governments
• Metahuman response agencies
• Authorized superhero teams

MTAS classifications are intended to assist in:

• Emergency response coordination
• Civilian evacuation planning
• Tactical deployment
• Interagency communication
• Infrastructure protection
• Continuity-of-government protocols

MTAS ratings are not criminal convictions, nor do they imply moral judgment.

Heroic individuals, government operatives, extraterrestrials, vigilantes, and civilians may all receive MTAS classifications if their abilities or activities meet operational thresholds.

MTAS Threat Level Summary

MTAS Level	Classification	Typical Scope	Typical Response	Example Threats
MTAS-0	Baseline Human Activity	Human-scale incidents	Law enforcement, intelligence agencies, emergency services	Organized crime, terrorism, espionage
MTAS-1	Localized Enhanced Threat	Building to city-block scale	Municipal metahuman units, local heroes, PHASE II liaison teams	Enhanced criminals, vigilantes, assassins, unstable experiments
MTAS-2	Urban Metahuman Threat	Neighborhood to metropolitan scale	Regional hero teams, PHASE II tactical command, enhanced containment assets	Giant robots, dangerous psychics, major metahuman battles
MTAS-3	National Metahuman Emergency	National or multi-region scale	National emergency coordination, military integration, multinational metahuman deployment	Alien strike forces, kaiju attacks, dimensional breaches
MTAS-4	Transnational Catastrophic Threat	Multiple nations or major world regions	Multinational metahuman coalitions, orbital surveillance, continuity-of-government systems	Rogue superintelligences, mass psychic contamination, planetary invasion beachheads
MTAS-5	Continental/Hemispheric Threat	Continental or hemispheric devastation	Civilization continuity measures, global emergency mobilization	Hyperstorms, biosphere corruption, advanced cosmic incursions
MTAS-6	Global Extinction Threat	Planetary extinction-level	Total emergency mobilization, offworld coordination, last-resort contingency systems	Moonfall scenarios, total planetary invasion, global dimensional collapse
MTAS-7	Existential/Reality-Level Threat	Universal or ontological collapse	Classification restricted	The Terror, multiversal destabilization, reality failure events

Threat Levels in Detail

MTAS-0

Baseline Human Activity

Incidents manageable by conventional authorities.

Examples Include:

• Organized crime
• Terrorism
• Espionage
• Conventional military threats

Typical Responders:

• Law enforcement
• Intelligence agencies
• Emergency services

Metahuman deployment is not normally authorized.

MTAS-1

Localized Enhanced Threat

The first recognized superhuman classification.

Threats at this level are dangerous to:

• Individual structures
• City blocks
• Localized populations

Examples Include:

• Enhanced criminals
• Minor vigilantes
• Low-level metahumans
• Expert assassins
• Unstable experimental subjects

Typical Responders:

• Municipal metahuman units
• Local heroes
• PHASE II liaison officers

MTAS-2

Urban Metahuman Threat

Threats capable of causing widespread urban disruption or catastrophic loss of life within a metropolitan area.

Examples Include:

• Giant robotic entities
• Destructive metahuman combat
• Dangerous psychic events
• Advanced armored criminals
• Significant biological outbreaks

Typical Responders:

• Regional metahuman teams
• PHASE II tactical command
• Enhanced containment assets

National metahuman organizations may be consulted depending on escalation risk and operational availability.

MTAS-3

National Metahuman Emergency

Incidents capable of destabilizing major national infrastructure or causing mass casualties across multiple regions.

Examples Include:

• Alien strike forces
• Kaiju attacks
• Large-scale weather manipulation
• Major dimensional breaches
• Top-tier metahuman warfare

Typical Responders:

• Multinational metahuman deployment
• Strategic military integration
• National emergency coordination

MTAS-3 incidents generally receive worldwide media coverage within minutes.

MTAS-4

Transnational Catastrophic Threat

Threats capable of destabilizing multiple nations or large sections of planetary civilization.

Examples Include:

• Planetary invasion beachheads
• Rogue artificial superintelligences
• Mass psychic contamination events
• Major spacetime destabilization
• Continental infrastructure collapse

Typical Responders:

• Multinational metahuman coalitions
• Orbital surveillance assets
• Continuity-of-government systems
• PHASE III strategic support

MTAS-5

Continental/Hemispheric Threat

Incidents capable of destroying or permanently destabilizing continental-scale populations or ecosystems.

Examples Include:

• Continent-scale biosphere corruption
• Hyperstorm events
• Advanced cosmic incursions
• Cascading dimensional collapse
• Mass extinction phenomena

At MTAS-5, governments may begin implementing civilization continuity protocols.

MTAS-6

Global Extinction Threat

Threats capable of causing planetary extinction or irreversible collapse of Earth civilization.

Examples Include:

• Moonfall scenarios
• Global dimensional destabilization
• Total planetary invasion
• Full-scale cosmic annihilation events

Typical Response Posture:

• Total emergency mobilization
• Offworld coordination
• Activation of last-resort contingency systems

Very few MTAS-6 incidents have been recorded in modern history.

MTAS-7

Existential/Reality-Level Threat

Classification Restricted.

MTAS-7 incidents involve:

• Ontological collapse
• Universal contamination
• Multiversal destabilization
• Reality failure events

Only a handful of MTAS-7 events are known to have occurred.

The most infamous remains the arrival of The Terror.

Threat Tags

In addition to numerical classification, incidents may receive operational tags describing the nature of the threat.

Core Tags

Tag	Meaning
TECH	Advanced technological threat
PSI	Psionic or mental phenomena
ARCANE	Magical or extradimensional activity
BIO	Biological or mutagenic hazard
COSMIC	Extraterrestrial or cosmic-scale threat
TRANSDIM	Dimensional instability
MEMETIC	Informational or psychological contamination
SWARM	Replication or mass-minion capability
TEMPORAL	Time-related anomalies
ENERGY	High-output destructive energy
MUTAGEN	Infectious transformation risk

Operational Tags

Tag	Meaning
MOBILE	Extreme mobility
TELEPORT	Instant relocation capability
COVERT	Infiltration or stealth capability
REGEN	Significant regenerative ability
IMMORTAL	Permanent neutralization unlikely
AURA	Passive environmental danger
HIVE	Distributed consciousness
DUPLICATE	Replication/cloning capability
UNSTABLE	Escalation risk unpredictable

Public Access and Advisories

Civilian MTAS alerts are distributed through the PHASE II Emergency Advisory Network, commonly called The Advisory.

The Advisory provides:

• Evacuation notices
• Shelter instructions
• Metahuman incident warnings
• Infrastructure closures
• Emergency preparedness guidance

Public MTAS data is intentionally limited. Certain operational details remain classified for security reasons.
