Sasuke encounters Itachi Edo Tensei during the Fourth Great Ninja War in the Naruto Shippuden series. Itachi is reanimated by Kabuto Yakushi using the Edo Tensei jutsu to fight against the Allied Shinobi Forces. Sasuke is shocked and conflicted to see his brother alive again, as he believed Itachi had died by his hands. Their encounter plays a significant role in Sasuke's character development and the resolution of their complicated relationship. **

Edo Tensei is a forbidden jutsu in the Naruto series that allows a user to revive the dead by reincarnating their souls into living bodies. The revived individuals are brought back with their original abilities and memories, making them extremely powerful and difficult to defeat. The technique was created by the legendary ninja, Tobirama Senju, and is often used by antagonists in the series to create an army of powerful warriors. However, Edo Tensei has significant drawbacks, such as the revived individuals being bound to the user's will and the fact that they can only be truly defeated by releasing the technique. **

Madara is so strong in the Edo Tensei because he was already an incredibly powerful and skilled shinobi in his lifetime. When he is brought back through the Edo Tensei, he retains all of his abilities, knowledge, and experience from when he was alive, making him a formidable opponent. Additionally, being revived in this way grants him an unlimited amount of chakra, allowing him to use his techniques without any limitations. This combination of his original strength and the benefits of the Edo Tensei make Madara a nearly unstoppable force. **

It is highly unlikely that Itachi will be revived with Edo Tensei in Boruto. Edo Tensei is a forbidden jutsu that brings back the dead as reanimated corpses, and Itachi's character arc has already been completed in Naruto. Bringing him back with Edo Tensei would undermine the impact of his sacrifice and redemption in the original series. Additionally, Boruto has focused on new characters and storylines, so it is unlikely that Itachi will be brought back in this way. **

Orochimaru first revives people with Edo Tensei during the Chunin Exams arc in the Naruto series. He uses the forbidden jutsu to revive the First and Second Hokage, Hashirama Senju and Tobirama Senju, in an attempt to gain their knowledge and power. This marks the beginning of Orochimaru's obsession with immortality and his quest for ultimate power. **

The Edo Tensei technique is used in the 124th episode of the anime series Naruto Shippuden. This technique is performed by Kabuto Yakushi, who uses it to resurrect several deceased ninja to fight for him in the Fourth Great Ninja War. The Edo Tensei technique plays a significant role in the war arc, as it brings back powerful and formidable opponents to challenge the allied shinobi forces. **

Sakura is a character from the Naruto series who is a skilled medical ninja and a member of Team 7. She is known for her exceptional strength and intelligence in battle. On the other hand, Edo Tensei Itachi is a reanimated version of Itachi Uchiha, a powerful ninja from the same series. Edo Tensei Itachi is brought back to life through a forbidden jutsu and is under the control of the person who summoned him, whereas Sakura is a living character who acts independently in battles. **

To use the Edo Tensei technique on oneself, one must first have a living sacrifice to use as a vessel for their own soul. The user then performs the necessary hand seals and releases a large amount of chakra to initiate the technique. By impaling themselves with a kunai or other sharp object, they can transfer their soul into the living sacrifice, effectively resurrecting themselves. However, this technique comes with great risks and is considered forbidden due to the potential consequences of bringing back the dead. **
