Which champions in LoL actually is over 9000 lore-wise? Which are the gods, the demigods or just plain old powerful beings in general in LoL? After I get enough results I would like to make a post ranking the top 10-15 most powerful champs in LoL, so, let’s do this! ( also, no hate =)) )
That would be Aspects and Celestials as they are some sort of demi-gods in league universe, so, the list would look like this: 
would add 
because they are literally DEATH. Kayle and Morgana are on the list because they are immortal beings.
After celestials and Aspects we have demons or demon posessed champions: 
The 3rd on the list would be undead: 
Than emperors and ascended: 
Rest are pretty much mages and warriors.
Powerlevel isn't the same as power, it was an early concept in Dragon Ball that was used in 1 arc and was scrapped later, relating to the amount of Ki energy that someone has, it's just that it became a meme in the west because of Vegeta but now it doesn't mean anything anymore. The strongest character in LoL that we know so far is Aurelion Sol
