Attack Potency

Credit to Vs Battles Wiki for this (mostly)

Standard sizes
The values for High 5-A and above are obtained from here. The calculation assumes that the blast is omni-directional (spherical), as is generally the case in most fictional occurrences, and that the energy output is sufficient to destroy the entirety of the cosmic structure.
 * Moon level: Earth's satellite Moon.
 * Small Planet level: Mercury.
 * Planet level: The Earth.
 * Dwarf Star level: Brown Dwarf star (specifically, the OTS 44).
 * Small Star level: VB 10.
 * Star level: The Sun.
 * Large Star level: Rigel
 * Solar System level: The star system known as the Solar System.
 * Multi-Solar System level: Instead of doubling the value of Solar System level, the distance between two such systems needs to be accounted for as well. The calculation for energy required to destroy two solar systems was done, with the following assumptions:
 * Distance between them as the minimum distance between Sun and the next closest star, the Alpha Centauri.
 * A spherical blast, strong enough to obliterate the contents of both solar systems at the same time.
 * Hence, the value obtained is the energy required to destroy two solar systems at a realistic distance.
 * Galaxy level: The Milky Way galaxy.
 * Galaxies in fiction tend to be destroyed completely, not dissociated. Hence, it is far more logical to index a common occurrence of compete obliteration instead of an obscure one like dissociation.
 * We have a different interpretation regarding black holes. Simply put, we disagree with the premise of utilization of black holes for energy outputs, primarily because black holes rarely follow any scientific logic whatsoever. To know more, continue to read here.
 * Multi-Galaxy level: Instead of doubling the value of Galaxy level, the distance between two galaxies needs to be accounted for as well. The calculation for energy required to destroy two galaxies was done with the assumptions:
 * Distance between them as the minimum distance between Milky Way Galaxy and the next closest similar-sized galaxy, the Andromeda galaxy.
 * A spherical blast, strong enough to obliterate the contents of both galaxies at the same time.
 * Hence, the value obtained is the energy required to destroy two galaxies at a realistic distance.
 * Universe level: Given that the universe's actual size is unknown, we do not know the amount of energy that would be required to destroy all matter within it. As such, the bare minimum value for the observable universe was calculated as a lower border instead (The PSRJ0348+0432 was used as a base). Any greater finite number is also included within this tier, whereas countably infinite numbers are included under High Universe level.

Omitted levels

 * Small Moon level: While most other tiers have been into 3 sub-tiers, Moon level does not have Small Moon level due to the existence of Multi-Continent level. Simply put, the two intersect, and Multi-Continent level is far more common than Small Moon.
 * Small Galaxy level: Same reason as the one for Small Moon level, with the tier clashing with Multi-Solar System level instead.
 * Large Galaxy level: Large Galaxy level was omitted because unlike planets, galaxies in fiction rarely specify the size of said galaxy, and instead go from galaxy to multiple galaxies. As such, a "Large Galaxy level" rating would not only be confusing, but also redundant.
 * Higher and lower layers/levels of reality: These levels are not listed because they are not restricted to the same parameters for energy requirement. The energy for such levels cannot be calculated.

"+" symbol
Currently misused to an extraordinary degree on the wiki, the "+" symbol should be used when the Attack Potency has been calculated to be greater than the average (arithmetic mean) of the high end energy level and low end energy level of a particular tier.

The "+" symbol can also be used if there exists a calculation extremely close to the arithmetic mean, and characters scale above the calculated feat by a wide margin, for example being able to defeat enemies on such levels with a single casual attack.

Example: Average of Large Building level is: [2 Tons (low end) + 11 tons (high end)]/2 = 6.5 Tons (the arithmetic mean). All energy levels from 2 Tons to 6.5 Tons should be listed as Large Building level, whereas all energy levels from 6.5 Tons to 11 Tons should be listed as Large Building level+.

High
Currently used to denote high end of a particular tier, it will here-on no longer be utilized in that manner. "High" will be utilized only if the instance matches with the revised Attack Potency chart.

Example: If a character is in the upper range of a tier such as Solar System level, said character will be listed as "Solar System level+", not "High Solar System level".

Low
Currently used to denote low end of a particular tier, it will here-on no longer be utilized in that manner. "Low" will be utilized only if the instance matches with the revised Attack Potency chart.

Example: There should be no usage of "Low 7-A", because it does not correspond with the revised Attack Potency chart.

At least
Should be used to denote the lower cap of a character, if the exact value is indeterminate.

At most
Should be used to denote the higher cap of a character, if the exact value is indeterminate.

Likely
Should be used to list a hypothetical statistic for a character, but inconclusive due to lack of feats or viable power-scaling. Probability of said hypothetical statistic should be favourable.

Possibly
Should be used to list a hypothetical statistic for a character, but inconclusive due to lack of feats or viable power-scaling. Probability of said hypothetical statistic should also be indeterminate.

Higher
This should be used to denote a character's weapons, techniques, or attributes that are much stronger than their base level, but still within the same tier. For example, a character that is Solar System level but has an attack that multiplies their power by 100 times. In this instance it should be written as “Solar System level, higher with that ability or technique”.

Furthermore, higher may also be used to denote a case where the character is possibly or likely a higher tier, but to what degree is not specified. This is specifically referring to cases such as “At least 4-B, likely higher” or “At least Solar System level, likely higher”.
