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.
energy beams: Shortly after coming to Earth-1, Harry stole a pulse rifle from Mercury Labs. It can fire a beam of energy which is very powerful, capable of blasting holes through walls and hurting durable enemies like King Shark.
power amplication and power nullifer(low): Wells took The Turtle's power after they caught him and created a device to siphon/harness Barry's speed energy and attaches behind the emblem of his suit.When Barry goes after Joey, the device works and permanently steals 2% of Barry's speed, slowing him down. Wells gives the energy to Zoom, who demands the rest. While going after Joey a second time, Iris is injured when Barry is too slow to save her. Wells later use the particles equation to increase Barry's speed. When they exchange Wally for Barry's Speed Force, Wells inserts the Speed Force transmitter into Barry's suit. Barry uses the treadmill so that his Speed Force can be extracted. All of his speed is taken and Zoom injects it to himself.
