In the World of Pokemon, we see many events, adventures, chaos, harmony, destruction, and Peace in the current timeline, but what if this is not the case this universe without being invaded is beyond alien invasion or other crises.
No this is completely different than just invasion, but what if any individuals want to corrupt/destroy/Enslaved the universe or even disrupt the universe whatever they feel like it from Villains from the past but also other universes they wish to conquer the planet?
But not all Hope is lost. When Villains come, they also come to Heroes and Antiheroes. Whatever their Ideals, Purposes, Paths, Second chances, and even Redemption, they always find ways to restore peace and Freedom to keep safe, and they will overcome hardships to Protect the World.
