And I like how the Prysm guy is standing right there.
Would that make him the "Chansey" of your region, since he's standing there with her?
Sort of. Prysm accompanies Nurse Joy out into the field because he's tougher and more athletic than Chansey but still has healing abilities. Chansey mostly stays in the Pokémon Center and takes care of the Pokémon when Joy is gone.
