Naruto Shippuden Temporada 2 Episódio 52

Sasuke begins to attack Naruto, but Sai restrains him only for them both to be blown away by Sasukes Chidori Nagashi. Sakura charges at Sasuke, but Yamato intervenes and winds up being stabbed by Sasukes unique blade infused with his Chidori. The Nine-Tailed Fox tempts Naruto with its power, but he refuses it. Sasuke sees this using his Sharingan, appearing in Narutos mind. The Nine-Tails says that Sasukes chakra reminds him of Madara Uchiha, then Sasuke suppresses the Nine-Tailed Foxs chakra. Before the Nine-Tailed Fox returns to its cage, it warns Sasuke not to kill Naruto, saying that he will live to regret it forever.
