Tier 1-A (Outerversal level): Characters who can significantly affect, create and/or destroy realms or states that fully transcend infinitely-layered hierarchies and/or dimensional levels on a conceptual or existential level, normally being portrayed as entirely external abstractions that lie outside of the applications of spatiotemporal dimensionality as a constant defined by physics on any level, even compared to infinite or uncountably infinite dimensions, usually by perceiving them as akin to fiction or something similarly insignificant.

However, do note that a character can qualify for this rating even if their verse does not have an infinitely-layered or equivalent cosmology, as long as it is either stated, shown or left very obvious that the character in question already bypasses the very nature of such structures altogether, in a way that simply "stacking" more of them logically would not allow one to reach their level of power / size.

Mathematically, 1-A has its size represented by further uncountably infinite cardinals beyond useful applications of certain measures (ℵ2 and onwards, most specifically) and can be extended unto greater levels of infinity, representing different complexities or qualitative "steps" on an Outerversal scale, in the same way 1-B and 1-C are divided. Characters who stand an infinite number of steps above "Baseline" Outerversal realms and structures are to have a + modifier in their Attack Potency section (Outerverse level+)
