What defines a Pokemon region in the anime and manga?
A region is a distinct setting with its own geography, gyms, and League; it hosts a set of Gym Leaders who award badges, culminating in the regional Elite Four and Champion.
How do Gyms operate in the anime/manga?
Each Gym is led by a Gym Leader; trainers battle to earn a badge, and collecting the required badges advances a trainer toward the League—with regional variations.
What are the Elite Four and Champion in this universe?
The Elite Four are the strongest trainers who guard the Champion; defeating them allows a shot at the Champion, the region’s top Pokémon master.
How do anime/manga gym progression differ from the games?
In anime/manga, progression is story-driven and may deviate from a fixed order; games use a linear badge-based progression with a set gym sequence.
