Eevee has an unstable genetic makeup that suddenly mutates due to the environment in which it lives. Radiation from various stones causes this Pokémon to evolve. Current studies show it can evolve into an incredible eight different species of Pokémon. The question of why only Eevee has such unstable genes has still not been solved. Its genes are so easily influenced by its surroundings, that even its face starts to look like that of its Trainer! Gigantamax energy upped the fluffiness of the fur around Eevee's neck. The fur will envelop a foe, capturing its body and captivating its mind.
