The following is a comprehensive overview of the hierarchical system which this wiki utilizes in order to properly categorize and index fictional characters, entities, and objects based on the scale of their feats, and the varying scopes which they can affect or create/destroy. However, it should always be kept in mind that, although Destructive Capacity and Area of Effect are some of the most primary ways to qualify for a particular tier, they are not the only ones. For instance, harming a character with a certain level of
Durability also allows another character to qualify for the corresponding tier.
Furthermore, it should be noted that characters from a higher tier are not necessarily invincible to entities of lower tiers, as certain powers and abilities can potentially bypass the difference in strength entirely, allowing the latter to contend with, or overpower such characters.
See this page for more information.
It is also important to know that the difference between the lowest and highest bounds of a given tier is extremely variable and can be absolutely massive in scale. Hence, being far stronger than a character that belongs to a certain tier does not necessarily qualify one for a higher rating.
