Pokémon universe
Pokémon are shown to exist instead of animals in their world. While most Pokémon resemble animals and may behave like them, there are many that do not resemble animals at all; taking on other forms such as plants, inanimate objects, machines, human-like forms or other more enigmatic and exotic appearances. Pokémon inhabit an extremely diverse range of habitats, ranging from the driest deserts to the lushest jungles, the deepest oceans to the highest mountains and everything else in-between, even space and other dimensions. Pokémon take up various ways of living in those places. However, all can be befriended by humans and made into potential allies.
