Ep. 41: Naruto's rage escalates as he destroys the Tenchi Bridge and confronts Orochimaru in the forest.

41

Naruto gets more enraged in his three-tailed state, and throws Kabuto away, who inadvertently knocks Sakura out too. Naruto's anger eventually escalates to him destroying the Tenchi Bridge and he takes to a forest to battle Orochimaru. Sai creates an ink bird and flies beneath the collapsing bridge to the site of Naruto and Orochimaru's battle, instead of catching a falling Sakura. Yamato saves her using his Wood Style Jutsu, and creates a wood clone to follow Sai. In the forest, Naruto's ever-increasing aggression causes his blood to mix with the Nine-Tails's chakra as his chakra cloak envelops him in the form of a four-tailed miniature fox.
