Tutum
Tutum class means it doesn't need much resources to contain and will not do anything in its chamber, doesn't mean it's not dangerous. Pretty simple. Think of it as this: A Tutum anomaly is put inside a box, it doesn't do anything.
Aprovleptos
Aprovleptos Anomalies are classified as that when its behavior cannot be unerringly predicted, either because the item is sentient, it behaves outside of current scientific knowledge, or its nature is simply poorly understood at present. Aprovleptos-class AEOs require more resources to capture completely or where containment isn't always reliable because it might escape. Think of it as this: If an Aprovleptos anomaly is an item inside a box and does random things, its aprovleptos
Mamatz
Mamatz Anomalies are exceedingly difficult to contain consistently or reliably. They pose a serious threat to the safety of the AENO Foundation personnel and the rest of humanity. Containment procedures for Mamatz-class SCPs are often extensive and complex, and AENO often lacks a solid understanding of the anomaly or the technology to properly contain or counter it. Think of it as this: Mamatz Anomalies can be put into the box but if they try to escape then thats a mamatz anomaly
Kasofi
Kasofi Anomalies are unable to be contained at all. They are able to end life at ease or with effort. Instead of chambers, there are multiple protocols to prevent Kasofi anomalies from ending life on earth. A. Keep it in check. B. Atleast attempt to kill it. C. Any other means. Think of it as this: Kasofi Are the items that cannot be put into the box and they also might destroy the planet the box is in.
Ozer
Ozer Anomalies can be the anomalies that contain, think of Ozer anomalies as the box and other anomalies as the little items inside. Thats an Ozer anomaly. Ozer anomalies can usually be docile or hostile, However it varies.
Kyriarh
Kyriarh Anomalies are anomalies that are able to be contained however will probably cause more destruction when contained. Think of it as this: Kyriarh are the bad items but when put in the box, they will probably destroy the box.
Tayenati
Tayenati Anomalies cannot be contained but also are unnecessary to be contained. Think of it as this: Tayenati Anomalies are items stuck outside the box but they are the same condition of what they would be inside the box, however cannot enter the box.
Null
Its just anomalies killed or deprived of their anomalous properties on accident, think of it as this: Null Anomalies are items that had a box but doesn't have it anymore
Uncertain
The object class is pending or uncertain
Absum
Anomalies that cannot be contained, danger or not. Think of it as this: An anomaly that is absum is attempted to be put into a box, however it cannot fit.
Complete
Anomalies that no longer require explanation as they are fully explained. Think of it as this: An anomaly that needed a box doesn't need a box.
Polloi
Anomalies that have Object classes not falling into typical standard classes.
