It has long been said that each of the nine tails embody an enchanted power. A long-lived Ninetales will have fur that shines like gold.
This fox-like, quadruped Pokémon is covered with a thick, luxurious golden-white fur. It has nine, long tails, each tipped with pale orange. There is a fluffy crest atop its head, and a small mane around its neck. Ninetales has gleaming red eyes that are said to give it the ability to control minds. Its ears are pointed, and it has long, slender legs with three-toed paws.
Ninetales is a very vengeful Pokémon that has been known to curse those who mistreat it. This intelligent Pokémon is able to understand human speech easily. It can live for 1,000 years, due to the energy within its nine tails, each of which is said to have a different mystical power. Flames spewed from its mouth can hypnotize an opponent. The anime has shown that it can swim. It can be found living in grasslands.
Ninetales is based on a fox, particularly the kitsune of Japanese legend, which have many tails, extremely long lifespans, and can breathe fire. After living a long time, kitsune take on spirit forms, which may explain why Ninetales can learn Ghost-type moves. In particular, Ninetales is based on the 九尾の狐 kyūbi no kitsune, a kitsune of advanced age whose fur has turned silver-gold, and, upon gaining its ninth tail, has gained powers equivalent to a deity, bearing omnipotence, omnipresence, and omniscience.
Ninetales is a combination of nine and tales, which itself may combine tails and fairy tales, from the Japanese myth it is based on. It may also reference the cat o' nine tails whip, which was historically used in military punishments.
