So, is it safe to declare Aurelion Sol the new strongest champion in the lore?

Not to jump the gun, but a near immortal celestial dragon that's been alive for hundreds of thousands of years and has control of the stars themselves is pretty hard to compete against.

In any case, I really hope this Targon event uses his potential in the lore well. Being able to have a literal god interact with the other residents of Runeterra is a very exciting concept.
