Attack Potency

Summary
Attack Potency, also referred to as Destructive Capacity, is a measure of a character, weapon, et cetera's capacity to cause major damage or other massive change (such as creation), mostly measured in units of energy, though in cases such as Spatial Manipulation and area-of-effect Reality Manipulation can be measured in units of area/distance if energy is not applicable. As such, attack potency is the blanket term for both types of cases, whereas destructive capacity is more appropriate for, well, destructive feats. At levels exceeding 3rd-dimensional power, destructive capacity becomes a non-factor, as it simply cannot be quantified. A character, weapon, etc. does not necessarily need to have direct feats to get a rating, but can receive a rating via scaling to another character/weapon/what-have-you.

Keep in mind, in terms of destructive capacity, area of effect has no bearing. Hence, characters and others that can destroy mountains, islands, etc. don't automatically receive Mountain Level or Island Level ratings, especially if said bodies are small. To reiterate, destructive capacity is measured by energy, not area of effect.

Descriptions of Potency Tiers
Below Average Human Level - attack potency below that of an average human teenager

Average Human Level - attack potency equal to that of an average human teenager or adult

Athletic Human Level - attack potency equal to that of the usual human athlete

Peak Human Level - attack potency ranging from that of the finest human athletes to the absolute peak of human strength

Street Level - attack potency stronger than that of a peak real-life human and often enough to fairly easily one-shot an athlete-level or peak-condition person, but not powerful enough to cause any significant structural damage to a structure the size and durability of a well-built wall or greater

Wall Level - attack potency ranging from powerful enough to puncture a well-built wall to destroying one outright

Room Level - attack potency powerful enough to destroy/envelop a normal-to-large-sized room, or harm someone/something of comparable durability

Small Building Level - attack potency sufficient to destroy/envelop a small building, such as a normal-sized one-story to two-story house, or harm someone/something of comparable durability

Building Level - attack potency sufficient to destroy/envelop a medium-sized building, such as a decent-sized office building, or harm someone/something of comparable durability

Large Building Level - attack potency sufficient to destroy/envelop a large building, such as a supermarket or lower-end skyscraper, or harm someone/something of comparable durability
