I still prefer the popular fan idea of Professor Amaranth being the true main villain of Pokemon Journeys.
Would have been a huge plot twist. His true plan was to use Mew for evil and all the members of Project Mew were actually being used by professor. By even gathering legendary and mythical Pokemon to his disposal.
And his actions affect global climate that affects everyone on the planet. Both the people and Pokemon. And the source of the action was in the Galar region.
Leaving the Master Eight and Project Mew to stop him and save the world
