The Superhero Database Classification number, or SHDB Class, is a number that represents the overall 'power' of a character. All traits of a character are used for calculating the Classification.
What it DOESN'T mean
This doesn't mean that a higher class would always beat a lower class character. But the bigger the difference in Class is, the more obvious it is who'll win in a fight.
How is this calculated
( INT^1.3 + (STR*0.5 )^2 + (SPE*0.5)^2 + DUR^1.6 + (POW + (SPS*SPL))^2 + COM^1.8 ) ^ TIER
Super Power Score and Level
Every Super Power has a score (SPS) that is used to calculate the Class. Each Super Power also has 3 levels (SPL). The level is set when connecting that Super Power to a character. The level determines the final score, of the Super Power, being used in the calculation.
Lain is explicitly referred to as "God of wired and top level of the Real-world hierarchy.
[...God.]
--What god?
[The God of Wired.]
--There's a God of Wired? You believe that?
[(silence)]
--Answer me.
[...There is if I believe there is...]
--That answer isn't good enough.
[...There is...a God...]
--All right, fine. The God of Wired is the god of the top level of the real world hierarchy--in other words,
a being that controls the entire world. Is that right?
[...Who are you?]

Wired exists as a projection and hologram of a our reality that is ontologically superior to our physical universe.
Author Konaka states that Lain speaks with the collective voice of Wired users via The Collective Unconsciousness.
While Lain manifested physically within the Wired at times, her true nature remains "unknowable God" ineffable being beyond all descriptive attributes and definitions, transcending all incl The Wired" Even the highest ontological layers like the (Tree of Life hierarchy) are said to be all emanations or extensions of God.
what else can i say about this girl? she just godstomp here. (Lol)
here why in my opinion, Lain would be Tier 0 = Boundless: omnipotent, omnipresent, omniscient using the new (Vsbattle wiki - tiering System) Transcendent over any and all forms of hierarchical extension. More specifically: They not only encompass the collection of all possible "qualities" represented by High 1-A+, but also exceed it utterly, existing beyond any and all distinctions between ontologies and any division between objects.
