After Utakata's full transformation into Six-Tails, he attacks Kakashi and Guy, emitting a corrosive alkali from its mouth, which Kakashi warned Guy not to touch. After Guy dissipated the gas with his Morning Peacock technique, the Six-Tails prepared to attack him again. After Son Gokū was resealed into the Demonic Statue of the Outer Path, Tobi, who was intent on going all-out from that point on, forced Utakata to fully transform into the Six-Tails. The opposing tailed beasts prepared to attack the shinobi, but they were rebuffed by a fully-transformed Naruto.
