For New Legends, I’ve been using a threat classification guide for AEGIS, though it hasn’t really come up. Figured I’d share.
~~~~~~~~
All metanomalies are given a two-character alphanumeric signifier, followed by a short descriptor. The first character is a letter which denotes the source of the metanomaly’s power, used to determine on short notice which equipment and techniques are most suited to neutralize the threat. The following list is considered in-progress.
A – Arcane. Power is drawn from mystic or otherworldly energies.
D – Dimensional. Power is native to another dimension.
E – Extraterrestrial. Power is native to another planet in this dimension.
M – Mutant. Power stems from a twist in evolution.
T – Technology. Power is based in science significantly more advanced than what is commonly available.
U: Unknown. Temporary label for new threats that have yet to be categorized.
X: Unique. Power stems from a source that does not fit into an existing category, which is not shared by any other metanomaly.
Z: Zero. Metanomaly does not have any powers that could be classified as abnormal, but they are in AEGIS databanks for other reasons.
The second character is a number which indicates the relative threat level of the metanomaly. The threat level may change over time, as it takes into account both the power and competence of the metanomaly. Past actions or trends of behavior are not taken into account.
0: Possesses no noteworthy advantage over unpowered humans.
1: Can be considered as dangerous as an armed human. Ordinary law enforcement are considered able and authorized to deal with the threat.
2: Beyond street level. Ordinary law enforcement should not approach. Single superheroes and AEGIS teams are considered able to deal with threat.
3: Significant threat. Only specialized AEGIS tac-teams and superhero teams should approach.
4: Threat to national security. Each known level 4 threat has a multijurisdictional task force headed by AEGIS devoted to monitoring and defending against it. Veteran superhero teams with special insight are on-call.
5: Existential threat. No specific countermeasures exist; in the event of a level 5 threat, every resource AEGIS has access to is brought to bear and we hope that Earth survives.
Lastly, a descriptor is appended, specifying the expression of the metanomaly’s power in order to advise which safety precautions should be taken.
