Where do you find a strong Pokemon on Vortex?

There isn't a game or world called "Vortex" that I'm aware of that is specifically related to Pokemon. Could you please provide more context or clarify what you're looking for?

For example, are you asking about:

* A specific game: Are you referring to a particular Pokemon game like "Pokemon Vortex" or a mod for a game?

* A Pokemon Go community: Are you asking about a specific community or server within Pokemon Go?

* A website or forum: Are you looking for a resource that discusses strong Pokemon?

Once I have more information, I can help you find the answer you're looking for!
