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.
C. S. Lewis replied: If Aslan represented the immaterial Deity, he would be an allegorical figure. In reality however, he is an invention giving an imaginary answer to the question, "What might Christ become like if there really were a world like Narnia and He chose to be incarnate and die and rise again in that world as He actually has done in ours?" This is not allegory at all. In one of his last letters, Lewis wrote, "Since Narnia is a world of Talking Beasts, I thought He [Christ] would become a Talking Beast there, as He became a man here. I pictured Him becoming a lion there because (a) the lion is supposed to be the king of beasts; (b) Christ is called "The Lion of Judah" in the Bible; (c) I'd been having strange dreams about lions when I began writing the work." However, the cosmology extends even beyond what is directly described in the books. As the scholar Michael Ward explained Lewis structured each of the seven Narnia books to correspond with one of the seven medieval heavens and their respective classical planets. This suggests Narnia is just one layer within a much grander celestial scheme that was common in medieval times.
in my opinion, aslan is most truly a character that fits the Tier 0 Definition well because, given that the Onion Layer used by C.S. Lewis to describe the different levels of reality in The Chronicles of Narnia. Each Narnia story takes place in its own fictional world, but they are implied to be "nested realities" - worlds within worlds.
The onion layer suggests that each subsequent layer of reality is more "real" than the one within it. The innermost layers are more symbolic or allegorical. In The Last Battle, when the characters enter Aslan's country, Lucy says that it is "more real and more beautiful" than Narnia. Tumnus compares it to peeling an onion, each circle larger than the last. This relates to Plato's allegory of the cave, where the shadows on the cave wall represent a lower level of reality compared to the real world outside. In Narnia, each new layer revealed approaches the ultimate reality.
