Attack Potency

Note: This is a work in progress.

Destructive Capacity
Destructive Capacity is the term used to determine the amount of damage a character can produce. It is normally the deciding factor of VS matches along with Speed. It is measured in units of energy.

Attack Potency
An alternative term for Destructive Capacity which has more direct meaning: The Destructive Capacity that an attack is equivalent to. A character with a certain degree of attack potency does not necessarily need to cause destructive feats on that level but can cause damage to characters that can withstand such forces.

We are aware that this technically violates the principle of conservation of energy, as it should logically disperse upon impact, but fiction generally tends to ignore this fact, so we overlook it as well.

Also, kindly remember that Attack Potency is the measure of Destructive Capacity of an attack, and as such, is measured via its energy damage equivalent. Hence, characters that destroy mountains or islands are not automatically mountain or island level, especially if they are small. The attack potency depends upon the energy output of the attack, not the area of effect of the attack.

Standard sizes
The values for 4-B 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.
 * Small Galaxy level: The Willman 1 galaxy.
 * 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, black holes cannot always be used for energy outputs, primarily because black holes rarely follow any scientific logic whatsoever. To know more, continue to read here. However, there are times where black holes can be calculated, and they can be used in those occasions.
 * 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.
 * 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 Dimensional levels: 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 is greater than the average (arithmetic mean) of the high end energy level and low end energy level of a particular tier.

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.
