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.
Not everyone who goes to the Warp can get power from it. The Warp is a dangerous and unpredictable place, and only those with sufficient psychic potential or the right kind of equipment can harness its power.
THe emperor Just stealed power from the warp thats why he get so powerful...but this still not power enough to heal his body. LOL
Knull is a primordial entity, he is purportedly unable to be killed, having existed for at least 13.7 billion years, having come into existence prior to the beginning of the seventh iteration of the multiverse itself; before the genesis of such concepts as life and death.
if we just compare marvel multiverse to warhammer 40k verse...and the fact that knull woke up from his sleep because of the big bang, he would certainly be older than the warp itself (IF the warp was created by the big bang too in warhammer 40k THAT IS JUST A THEORIE).
