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.
Nightmasks such as Izanami Randall and Adam Blackveil can access and navigate the Superflow. They can use it to transport from one location to another.[14][16][17][4][6]
Additionally, high-level cosmic beings like Abstracts, Galactus, Aspirants, Celestials, etc. can also enter the Superflow at will.[5][8][2][18] The Superflow has been described as the level of aspects, the realm of the abstract entities, and a conceptual space where signifier and signified become one, metaphors and reality meet, and concepts make war.[8][2] Combat in the Superflow is a metaphor and abstract entities can be directly damaged there.[5][2]
