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.
I think Sharon can stay alive for one minute, dodging attacks. But since no-one else mentioned the 1 minute rule, I'm just going to ignore it. :)
Read virtually any comic with Agent 13 in it, she takes down way better fighters.
1. Agent 13 is a much, much, much better fighter.
2. She consistently takes down large groups of people with much worse weapons than a chainsaw.
3. Leatherface is just a dumb dude with a chainsaw, who gets defeated by normal humans.
4. There could be 10 Leatherfaces and one Agent 13, and she still wins easily.
This is a stomp
*You wouldn't even see Hewitt until it was too late. He had a lair and you were at the wrong place at the wrong time to even face him. Then, he patiently waited for the signal--given by his dad(a noise)--then he runs out like a track star wielding a chainsaw like a sword all of a sudden; do you understand the gravity of that statement or the athleticism of that statement? Does she defeat Bane, if he had a chainsaw? Batman lost without that. She'd have to defeat a man-killing grizzly bear to even have a shot. DO YOU SAY SHE DOES THAT?! I DON'T. AND, EVEN THEN, A CHAINSAW IS MUCH BETTER THAN A GRIZZLY'S CLAWS AND HE'S MORE INTELLIGENT THAN A GRIZZLY!
