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.
Like many members of her race, Nightside is a shadow caster. She is able to draw darkness from the extradimensional Darkforce Dimension. Others believe her powers is inherent, but she keeps it as a secret that she draws it from another dimension. With her power, she can displace projectiles, create darkness, or teleport her opponents into the void.
Nightside also has the ability to fly, though this may be due to an Imperial Guard "flight belt" rather than her own inherent powers.
