 * Red-Pill: This Pokémon's isolated habitats led to it becoming vulnerable to disease. Almost none remained in the region, and those who survived wanted revenge for the accident that wiped them out.
 * Blue-Pill: All Primyo are the same, and the only ones who propagate this lie are those who waged this genocide of the species to begin with.
