Tier system

Tier Bartsimpson0 brain:
The lowest of the lowest NOTHING AND NO ONE can be lower than this tier there is only one person in the Cosmos that has this tier

10-C: Below Average Human level

Low 5-B: Small Planet level
Characters who can destroy smaller planets or structures almost the size of a planet. This also extends to those who can easily harm characters with small planet level durability.

5-B: Planet level
Characters who can create/destroy a planet. This also includes characters who can destroy objects that are relatively comparable in size to a planet (At least Mercury sized, as that's the smallest planet in the local solar system)

5-A: Large Planet level

High 5-A: Dwarf Star level
Characters who can destroy, create or effect small stars such as white dwarf stars. This also extends to those who can easily harm characters with dwarf star level durability.

Low 4-C: Small Star level
Characters who can destroy, create or effect small stars that are bigger than white dwarfs but are generally lesser than a main sequence star (such as our sun). This includes harming characters with small star durability or effecting structures of this nature

4-C: Star level
Characters who can create/destroy a star. This tier is often given to characters who can effect a star of an unknown size or through unknown means.

High 4-C: Large Star level
Characters who can create, destroy or effect larger stars such as Red Giant or structures much larger than the sun. This includes harming characters with large star durability or creating pocket dimensions with a single sun

4-B: Solar System Level
Characters who can create/destroy a solar system. This tier can also be assigned to characters who can create/destroy dimensions that contain at least an Earth-Sun Distance or destroying a Neutron Star

4-A: Multi-Solar System level
Characters who can create/destroy multiple solar systems. This tier also encompasses characters who can create/destroy dimensions that contain at least two stars or a starry sky

3-C: Galaxy level
Characters who can create/destroy a galaxy.

3-B: Multi-Galaxy level
Characters who can create/destroy multiple galaxies. This tier is also for characters who can effect large sections of the entire universe, as doing such a feat would be this level by default

3-A: Universal (Cube Being)
This category is separated in the following manner:


 * Universe level: Characters who can destroy all of the physical matter within an observable universe at full power. More specifically, usually via an, omnidirectional energy blast, or a , that encompasses all of the stars and planets within a universe.
 * High Universe level: Characters who have an infinite degree of 3-dimensional power. Alternately 4-dimensional power that is shown as completely qualitatively superior to 3-Dimensional beings, but is less than universal in scale. Or that allows them to create large parts of a universal continuum. Take note that 4-D power should logically always be superior to countably infinite 3-D power, so characters within this tier are not necessarily comparable. Also take note that we consider most small scale time-space abilities as hax, not as AP.

Other requirements include


 * Characters that have infinite power/infinitely growing power
 * Characters who can contain and attack with infinite amounts of energy

2-C: Multi-Universe level
This category is separated in the following manner:


 * Universe level+: (Low 2-C) This is for characters who can destroy and/or create the entire 4-dimensional space-time of one universe, not just the physical matter within one. For example, an entire timeline.
 * Multi-Universe level: Characters who can destroy and/or create up to 1000 universal space-time continuums.

2-B: Multiversal
Characters who can create and/or destroy 1001 to any higher finite number of physical universes.

2-A: Multiversal+
This category is separated in the following manner:


 * Multiverse level+: Characters who are capable of effecting an infinite number of universal space-time continuums. Each of them having to contain their own space-time flow and not be interconnected (otherwise that would be Low 2-C, but above baseline)
 * High Multiverse level+: Characters who are 5-dimensional, and/or can destroy and/or create 5-dimensional space-time of a not insignificant size. This can also apply to characters who can create and destroy infinite multiverses of infinite size (Although this is a case by case basis, most often not being applicable and being usually above baseline 2-A)

1-C: Quantaverse Level
These are 6-11-dimensional characters. Even 6-dimensional characters can logically easily destroy a more than countably infinite number of 5-dimensional space-time continuums, and 7-dimensional characters exceed that scale a more than countably infinite number of times, and so onwards. However, these characters do not exceed the 11-dimensional scale of the complete totality of a full multiverse, as defined by M-Theory.

This category is separated in the following manner:


 * Quantaverse level: 6-dimensional characters, 7-dimensional, 8-dimensional and 9-dimensional characters. Alternatively ones that are positioned at an unknown/unspecified level within this category.
 * High Quantaverse level: 10-dimensional and 11-dimensional characters.

1-B: Hyperversal
12-dimensional beings and above. These are characters that are beyond complex multiversal scale.

"Hyperverse" in this case comes from two words: "Hyper", which is used in mathematics to designate higher-dimensional space, and something extreme, above or beyond the usual level. As well as "verse" as a short for "universe". So it is intended as a description of a superior higher-dimensional existence, beyond conventional reality.

12-dimensional characters are a more than countably infinite number of times greater than a full complex M-Theory multiverse, 13-dimensional character are a more than countably infinite number of times greater than that and so onwards.

This category is separated in the following manner:


 * Hyperverse level: Characters with a finite number of dimensions greater than 12.
 * High Hyperverse level: Infinite-dimensional Hilbert space characters.

Take note that even if a character is a more than countably infinite number of times superior to an infinite-dimensional space, or similar, it would still usually only qualify for High 1-B, as long as the character does not transcend the concepts of time and space altogether.

Low 1-A: Low Metaverse Level
Characters who are still bound to dimensions but vastly exceed Infinite-Dimensional Space (also known as Hilbert Space).This tier can also be assigned to characters who transcend High 1-B structures but don't exactly transcend the concepts of space and time (Simply just existing beyond standard hilbert spaces or simply an infinity + 1 situation)

1-A: Metaverse Level
Characters who exist far beyond the conception of Spatial Dimensions and exist within the realm of Metaphysics. Beyond all Science and Totality

Metaverse Level refers to entities who are beyond all iterations of Space-Time and or Spatial Dimensions existing as abstract, formless and truly dimensionless entities, Destruction of Infinite-Dimensional Space and Space-Time is insignificant to these entities as no number of dimensions can be applied to them as they are beyond this concept entirety

Note: Metaversal Entities have infinite superiority to over Infinite-Dimensional Spaces and Dimenionsal Structures along with having conceptual control over Dimensions

High 1-A: High Metaverse Level
Characters who are extremely powerful even for beings relative to the 1-A Tier and far exceeds those who have met the requirements of 1-A

This tier is basically for entities who's power is short of omnipotence, usually being only limited or restricted to a Tier 0 (Omnipotent) entity or simply has very few limitations to what they can they, usually High 1-A characters infinitely transcend ordinary 1-A's and directly second to a Omnipotent entity, Note that being infinitely superior to a 1-A doesn't automatically make you a High 1-A character as you have to have few limitations to what you can do

0: Boundless
Beings who's existence lies of being beyond everything that can be conceptualized and is beyond all abstract, mental and physical limitations like Life, Death, Cause and Effect, Dualism, Nonexistence, Existence and so on. This tier has no true endpoint and nothing can be stronger than this tier.

there're realities like joke battles wiki, these realities often say they got power above Tier 0 but that's actually not true. everything that would go above Tier 0 would just be Tier 0 again, because there's nothing beyond that point
