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.
So these worlds can’t be planets, cause they contain stars and nebulas which are referred to as stories. In Talismen we see that these “worlds” are contained within dimensions
In world upon world—in worlds strung side by side in multiple dimensions throughout infinity—evils shrivel and disperse: despots choke to death on chicken bones; tyrants fall before assassins’ bullets, before the poisoned sweetmeats arrayed by their treacherous mistresses; hooded torturers collapse dying on bloody stone floors. Ty’s deed reverberates through the great, numberless string of universes, revenging evil as it spreads. Three worlds over from ours and in the great city there known as Londinorium, Turner Topham, for two decades a respected member of Parliament and for three a sadistic pedophile, bursts abruptly into flame as he strides along the crowded avenue known as Pick-a-Derry. Two worlds down, a nice-looking young welder named Freddy Garver from the Isle of Irse, another, less seasoned member of Topham’s clan, turns his torch upon his own left hand and incinerates every particle of flesh off his bones.
These dimensions/worlds are in turn participated by another hierarchy of worlds called a microcosm and this repeats itself infinitely on a barber pole and the universes that contain them are called macrocasms.
This is consistent, because Jack Sawyer (in the Talisman) goes up within this worlds within worlds hierarchy and it only equates to a single step on the tower.
In The Gunslinger, we learn that the gap between of these each universes are like a grain of sand on a beach/an atom on a blade of grass/an infinite of gnats in comparison and this regression happens infinitely with Man In Black stating that creation doesn’t only rise to one infinity but an infinite number of them.
