>>15598769Long ago, the Pokérus virus came to Earth on a meteor. That virus was spread all around infecting most animals, some objects, and even a few humans. Among those infected were a dog an d acat, the dog and cat loved each other very much and, while being infected with similar strands of Pokérus, fucked and somehow, were mutated enough by it to reproduce. The offspring was a dog-like feline that was very prone to genetic mutations. A new species was born amongst the apocalyptic genetic chaos, Eevee.
TL;DR: Pokémon takes place in a post-apocalyptic Earth, where humans managed to recreate society exceedingly well.Also, nice 69s.
