Abilities
The Three-Tails has the ability to create coral, and swim at very high speeds. Like all Tailed Beasts, it has an enormous amount of chakra compared to most ninja and can form the Tailed Beasts' ultimate attack, the Tailed Beast Ball. Tobi suggested that Kisame would have been a better choice for capturing the beast, given its affinity for water. Deidara claimed that because the Three-Tails lacked a jinchuriki host, it wasn't intelligent enough to control its own strength. In the anime, its abilities were greatly elaborated upon, many of which dealt with its size: it could roar to repel attacks; it could produce a large tidal wave that spread away from it in all directions; it could strike with any of its three spiked tails to break through most defences. Its skin was resistant to attack in a similar fashion. With these abilities, it overwhelmed Guren's Crystal Release several times over the course of their battle.
Of the beast's more specialised abilities, it could produce a hallucinogenic mist that exploited the victim's insecurities and forced the victim to face them. It could also shoot two powerful chakra infused water balls at the same time. When it ate something, thousands of miniature versions of itself would attack what it had eaten within its stomach, presumably to speed up the digestion process.
