Characters who stand at the threshold of human strength and capabilities, represented by Olympic level athletes or rigorously trained martial artists, as well as larger animals.
It is important to note that, despite being named "Street level", this tier has nothing to do with actually affecting an entire street, with the name being more of a reference to street fighters as portrayed in martial arts movies and the like.

Tier 3: Cosmic
This tier is broken into the following sub-tiers:
3-C: Galaxy level
Characters capable of creating and/or destroying a galaxy, when the space between celestial bodies is taken into account, as opposed to merely the matter encompassed by them.
3-B: Multi-Galaxy level
Characters capable of creating and/or destroy multiple galaxies when the space between celestial objects is taken into account as well.
3-A: Universe level
Characters who can destroy all celestial bodies within a volume at least equivalent to the observable universe via an omnidirectional explosion, alternately create or significantly affect[1] a universe of comparable size, which does not involve the destruction and/or creation of space-time.
High 3-A: High Universe level
Characters who demonstrate an infinite amount of energy on a 3-D scale, or those who can affect an infinite 3-D area or an infinite number of finite or infinite universes when not accounting for any higher dimensions or time, or more generally any realm of comparable size. Large numbers of infinite universes, unless causally closed from one another by a separate spacetime or existence, only count for a higher level of this tier. Being "infinitely" stronger than this level, unless uncountably so, does not qualify for any higher tier.
Tier 2: Multiversal
Low 2-C: Universe level+
Characters who are capable of significantly affecting[1], creating and/or destroying an area of space that is qualitatively larger than an infinitely-sized 3-dimensional space. Common fictional examples of spaces representing such sizes are space-time continuums (the entire past, present and future of 3-dimensional space) of a universal scale. However, it can be more generally fulfilled by any 4-dimensional space that is either:
A) Equivalent to a large extra dimensional space. That is, a higher-dimensional "bulk" space which embeds lower-dimensional ones (Such as our universe) as subsets of itself, whose dimensions are not microscopic / compactified.
B) Portrayed as completely transcending lower-dimensional objects and spaces in the setting of a given work of fiction.
2-C: Low Multiverse level
Characters who can significantly affect[2], create and/or destroy small multiverses which can be comprised of several separate space-time continuums ranging anywhere from two to a thousand, or equivalents.
2-B: Multiverse level
Characters who can significantly affect[2], create and/or destroy larger multiverses which comprise from 1001 to any higher finite amount of separate space-time continuums.
2-A: Multiverse level+
Characters who are capable of significantly affecting[2], creating and/or destroying a countably infinite number of space-time continuums.
Tier 1: Extradimensional
Characters who can significantly affect spaces of qualitatively greater sizes than ordinary universal models and spaces, usually represented in fiction by higher levels or states of existence (Or "levels of infinity", as referred below) which trivialize everything below them into insignificance, normally by perceiving them as akin to fictional constructs or something infinitesimal.
Low 1-C: Low Complex Multiverse level
Characters who can affect, create and/or destroy the entirety of spaces whose size corresponds to one to two higher levels of infinity greater than a standard universal model (Low 2-C structures, in plain English.) In terms of "dimensional" scale, this can be equated to 5 and 6-dimensional real coordinate spaces (R ^ 5 to R ^ 6)
1-C: Complex Multiverse level
Characters who can universally affect, create and/or destroy spaces whose size corresponds to three to five higher levels of infinity greater than a standard universal model. In terms of "dimensional" scale, this can be equated to 7 and 9-dimensional real coordinate spaces (R ^ 7 to R ^ 9)
High 1-C: High Complex Multiverse level
Characters who can universally affect, create and/or destroy spaces whose size corresponds to six to seven higher levels of infinity greater than a standard universal model. In terms of "dimensional" scale, this can be equated to 10 and 11-dimensional real coordinate spaces (R ^ 10 to R ^ 11)
1-B: Hyperverse level
Characters who can universally affect, create and/or destroy spaces whose size corresponds from 8 to any higher finite number of levels of infinity above a standard universal model. In terms of "dimensional" size, this can be equated to 12-dimensional real coordinate spaces and up (R ^ 12 and up)
High 1-B: High Hyperverse level
Characters who can universally affect, create and/or destroy structures whose size is equivalent to a countably infinite number of qualitative sizes above a universal model, usually represented in fiction by endless hierarchies of layers of existence, each succeeding one completely trivializing the previous into insignificance, or more generally a space with countably infinite dimensions.
1-A: Transcendent
Characters who functionally transcend the rest of the Tiering System. These characters are of infinitely higher power than even those that have absolute power over a single infinite hierarchy of levels of infinity.
Low 1-A: Low Outerverse level
Characters who can affect objects with a number of dimensions greater than the set of natural numbers, meaning in simple terms that the number of dimensions is aleph-1 (An uncountably infinite number, assumed to be the cardinality of the real numbers themselves), and therefore that such objects fully exceed High 1-B structures, which have only a countably infinite number of dimensions. More information on the concept is available on this page.
Note that, if the High 1-B structure in question is a hierarchy of levels of existence, then simply being at the top of such a hierarchy does not qualify a character for this tier without more context, and an additional layer added on top of the "infinity-th" level of this hierarchy is likewise not enough. To qualify as an equivalent of the above description, they need to surpass the hierarchy as a whole, and not simply be on another level within it.
1-A: Outerverse level
Characters who can affect objects with a number of dimensions equal to the cardinal aleph-2, which in practical terms also equals a level that completely exceeds Low 1-A structures to the same degree that they exceed High 1-B and below. This can be extrapolated to larger cardinal numbers as well, such as aleph-3, aleph-4, and so on, and works in much the same way as 1-C and 1-B in that regard. Characters who stand an infinite number of steps above baseline 1-A are to have a + modifier in their Attack Potency section (Outerverse level+).
High 1-A: High Outerverse level
Characters who can affect objects that are larger than what the logical framework defining 1-A and below can allow, and as such exceed any possible number of levels contained in the previous tiers, including an infinite or uncountably infinite number. Practically speaking, this would be something completely unreachable to any 1-A hierarchies.
A concrete example of such an object would be an inaccessible cardinal, which in simple terms is a number so large that it cannot be reached ("accessed") by smaller numbers, and as such has to be "assumed" to exist in order to be made sense of or defined in a formal context (Unlike the standard aleph numbers, which can be straightforwardly put together using the building blocks of set theory). Even just the amount of infinite cardinals between the first inaccessible cardinal and aleph-2 (Which defines 1-A) is greater than cardinals such as aleph-0, aleph-1, aleph-2, aleph-3, etc., and even many aleph numbers whose index is an infinite ordinal.. More information on the concept is available on this page.
Tier 0: Boundless
Characters who can affect objects which completely exceed the logical foundations of High 1-A, much like it exceeds the ones defining 1-A and below, meaning that all possible levels of High 1-A are exceeded, even an infinite or uncountably amount of such levels. This tier has no endpoint, and can be extended to any higher level just like the ones above.
Being "omnipotent" or any similar reasoning is not nearly enough to reach this tier on its own; however, such statements can be used as supporting evidence in conjunction with more substantial information.
