Losing to Champion

What actually happens when you beat Elite 4 but Reukra still managed to win the final battle? Is he a new champion? Demigod? Best trainer in the world?

Well, I mean, I guess?

Obviously, you’d just lose the battle and go back to the Pokemon League building.

Yeah I did and suddenly Elite 4 has stronger pokemons, about 110 lvl, as if I was rematching them. Don’t know whether it is how it’s supposed to be or not.

The elite 4 scale to your Pokemon’s levels starting at level 88

Well so I must’ve did something wrong then, thanks
