Actually, you can get avatars from evolving and catching certain Pokemon.
I've gotten avatars from evolving Zamazenta (crowned) and catching Zacian and Darkrown.
A friend of mine wants to give me access to his account where I can do sidequests for him.
I just want to be sure that this wouldn't be against the rules.
About a month ago, I saw a few gen 9 pokemon in the battle tower.
They only appeared for one day, but I did get this screenshot of one of them.

I think catching Eternatus for an event would be a good idea, but I seem to remember Patrick saying that when Urshifu is released, it wouldn't be an event pokemon.
Since Pokemon Vortex isn't an official pokemon game, Nintendo would probably shut it down if there would be an anime based on it.
It is an interesting idea, though.
