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.
REV-9 IS REALLY STRONG...REV-9 when combine is strong enough slam T-800 hard enough to fly back and cave in a forklift.
REV-9 when combine was fighting the total strength of T-800 pushing, and Grace pulling.
And his Liquid part of REV-9 was strong enough to restrain T-800, and the solid part of REV-9 was able to break off T-800s hyper alloy arm.
Durability :
Rev-9 once was shot at close range by an M4 carbine equipped with an M203 grenade launcher (a grenade launcher that was also used against him during the film)
But why he is so resilient? REV-9 in interviews is stated to be made of a Carbon-Based Endoskeleton, and Liquid Carbon Substance Alloy.
ALSO REV-9 Endoskeleton takes rapid fire shotgun blasts and is fine
REV-9 Endoskeleton takes a bazooka blast head on, and is undamaged, but is temporary KOed.
His biggest feat of resistance was when REV-9 falls thousands of feet from the sky into a shed. It gets up with "NO DAMAGE" as soon as landing.
Speed:
REV-9 splits between Sarah Connors shot gun blast as she fires.
REV-9 at close range side steps a 40mm grenade launcher.
Accuracy:
REV-9 scans through the flesh and scans the T-800s endoskeleton.
And Being an advanced model of artificial intelligence, the REV-9 has great accuracy during all its attacks as seen in the film, it was capable of even piloting a helicopter REV-9 shows incredible accuracy firing a assault rifle one handed, while flying a copter at vast distance. Still managing to hit the Major.
In hand to hand combat or throwing weapons he always hit his oponents
Liquid Metal :
Unlike the t-1000, the REV-9 has better control of its liquid metal...
REV-9 is able to project multiple blades from its body to stab multipole foes in its vicinity.
Also REV-9 liquid metal catches T-800s fist and shreds his flesh off the arm in the movie showing his deadly capacity.
