"Who Are You?" (てめーは誰だ!!, Temē wa Dare da!!) is episode 343 of the Naruto: Shippūden anime.
With Kurama encouraging him, Naruto enters Tailed Beast Mode and attacks Tobi. Meanwhile, a hesitant Kakashi is in disbelief of the masked man's identity but Guy ultimately snaps him out of it. As the battle rages on, a defiant Naruto informs Tobi that he isn't alone, not when he has Kurama, Killer B and Gyūki as well as Kakashi and Guy by his side. This prompts Kakashi to fight and now, Kakashi joins in with Guy helping him. Tobi unleashes a shower of gigantic chakra receivers, paralysing both B and Gyūki. Naruto creates a shadow clone and it charges forward with Rasengan while the original prepares a Tailed Beast Ball with Gyūki providing cover. As Naruto launches his technique, Tobi simply phases through and with that, fully enters the other dimension. There, he notices the clone from earlier and realises that Kakashi did not just teleport the Rasengan but the clone itself.
With little time to react, Tobi is hit by Naruto's Rasengan; his mask shattered into pieces. Watching on, Kakashi and Guy are shocked to see that the masked man is their former comrade, Obito Uchiha. Naruto questions who the individual is, to which Guy responds that he is their former comrade who was supposedly killed in action during the previous war. In response to Kakashi's question, Obito explains that what he did up until now is because he let their former team-mate, Rin Nohara die. Naruto motivates a devastated Kakashi as Obito's plan to conquer the world needs to be stopped. Obito attacks the group with his Fire Release: Blast Wave Wild Dance technique but Naruto intercepts with Kurama's tails. Just then, Madara appears alongside Obito, much to the others' surprise.
- When Obito is panting during his training for his second Chūnin Exam, his nose disappears.
- When the main examiner for the fight gestures for the fight between Team Kakashi and Team Guy to begin, the thumb on his left hand is missing.
