As part of its ongoing efforts to promote every single Pokémon out there, The Pokémon Company has shared special content dedicated to Ninetales:
Did you know? Ninetales is vindictive and relentless by nature. Those who cross it even once will be cursed for a thousand years, along with their descendants. The flickering flames it spews from its mouth leave its opponents hypnotized. Then, this extremely intelligent Pokémon attacks.
