Kurama-Being the strongest of the nine tailed beasts, it is said that Kurama can create tsunamis and flatten mountains with just a single swipe from one of its tails. With its massive supply of chakra, it can turn its roar into a powerful shock wave that can repel and destroy anything within its radius, increase its physical strength and speed, and fire Tailed Beast Balls.
Gyuki-Gyūki was said by both Kisame and Kurama to be the second strongest of the tailed beasts. With its great supply of chakra, it can fire massive chakra blasts. Despite their massive size, its horns are incredibly sharp, coupled with Gyūki's massive physical strength, it is able to easily impale a human being. During Naruto's battle with Kurama within his subconscious, it was shown that Gyūki had enough strength to temporarily restrain and contain a direct Tailed Beast Ball from Kurama, but was knocked out of the battle afterwards because of it. Its strength is so great that it could stop Isobu in full motion using only its extended tentacles, along with swiping Kokuō aside at the same time.[7][8] It was able to endure being burned by Amaterasu for a considerable amount of time, and continued battling after being gored by Kokuō and slammed by Son Gokū. 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,[9] and even fast enough to block Amaterasu with its fist.[10] A single Tailed Beast Ball from it could penetrate nine of the thirty-six barriers without even exploding.[11] 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.
Naruto also noted that it was extremely fast despite its massive size.In addition, it was shown that even when most of its chakra was taken by Naruto during their battle in his subconscious, Kurama still had enough to create a Tailed Beast Ball as big and powerful as that of a combined ball of five tailed beasts.
