Abilities
The Eight-Tails was said by Kisame and the Nine Tailed Demon Fox to be the second strongest of the tailed beasts. With its great supply of chakra, it can fire massive chakra blasts. During Naruto's battle with the Nine-Tails within his subconscious, it was shown that the Eight-Tails had enough strength to temporarily restrain and contain a direct Tailed Beast Ball from the Nine-Tails, but was knocked out of the battle afterwards because of it. It is able to endure being burned by Amaterasu for a considerable amount of time. Its tentacles offer it several additional appendages with which to interact with its surroundings and strike targets, but they are also easily severed. Even with its immense size, it has shown a high level of speed when it attacks, and even fast enough to block Amaterasu with its fist. A single Tailed Beast Ball from it could penetrate nine of the thirty-six barriers without even exploding. Going with its octopus theme, it can also produce ink to blind opponents as well as form ink clones to bind the enemies. It can also generate enormous tornadoes which can destroy an entire forest with ease.
The Eight-Tails has been shown to be very intelligent, explaining the mechanics of the Tailed Beast Ball to Naruto, the weaknesses of his Nine-Tails Chakra Mode, as well as pointing out that until he and the Nine-Tails reach a formal agreement, Naruto will not be able to fully transform or perform the Tailed Beast Ball. The Eight-Tails even coached B in tactics on how to counter Kisame's water-based techniques. He is also very perceptive as he later worked out that the Gold and Silver Brothers were revived, after witnessing Naruto sense the Nine-Tails' chakra coming from outside of the training place that he and B were confined, correctly deducing that Orochimaru's Impure World Resurrection was being used by someone participating in the war.
