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.
Other feats include breaking Stormbreaker, instantly killing a monster by throwing Mjolnir across the 10 realms and headshotting it (without using the Power Cosmic), blasting holes through Galactus, fighting two years straight against thousands of enemies without any food, water, or sleep as regular Thor, casually KO's Beta Ray Bill, holding back the Black Winter (a multiversal being that has destroyed multiple universes), and more. Warlock couldn't defeat Mephisto without his staff and the Soul Stone.
Cosmic King Thor holds the advantage in strength, durability, and overall power.
On the other hand, Adam Warlock has a much bigger title and overall universal position than CKT. Adam Warlock is The Champion of Life, and was created to be perfectly superior, and has managed to evolve past that. Unlike CKT, Adam Warlock is beyond fate itself, which even Galactus isn't, and Adam has high levels of fate manipulation power, even above beings like Mephisto. As the Champion of all Life in the universe, Warlock has extraordinary power, some of which is unexplored. With the soul stone Warlock has even more of an advantage, as not only does it give him an entire pocket dimension to draw power from, but also incredible soul manipulation powers. With both fate and soul manipulation powers, combined withhis raw power and his cosmic role as the champion of all life, Warlock is too much for even CKT. Adam Warlock also has high levels of cosmic knowledge and overall universal awareness, far above even the knowledge of Odin. Warlock is also extremely intelligent, far superior to CKT. CKT has basically 3 main sources of power. The first is the power of Thor ofc, and Warlock has been shown to be far more powerful than Thor on many occasions, like in Infinity Gauntlet and Infinity War. The second source of CKT's power is the power cosmic, and Adam is shown to be far above the power of the silver surfer, who almost definitely has more cosmic power than CKT (just in reference to the power cosmic, not to other powers ofc). And finally the power of the Odinforce, but as powerful as the odinforce is, Warlock is has fate and soul manipulation, and is the literal champion of all life in the universe. Also, CKT killing Galactus is BS! IT. SHOULD. NOT. HAVE. HAPPENED. That's not me getting mad at you, that's just me getting mad at the comic lol.
It's close, but Adam Warlock comes out on top this fight.
