A while back I wrote this alternate story arc in response to the survey question: Would you rather Itachi be alive instead of Sasuke? I said yes and was asked to defend my position with an alternative to what actually happend. Instead of doing a big long fan fic, I just did a quick explaination below… Let me know what you think.
Alternate ending to the Sasuke Itachi fight and future of the manga:
Imagine if the story were exactly the same except when Itachi collapses on the ground at Sasuke’s feet he didn’t die. He’s just so beaten down that he can’t move any more. Madara thinks he’s dead, swoops in, kills a vulnerable Sasuke in one blow and takes his eyes.
Leaving Itachi for dead, Madara leaves the scene instructing Zetsu to digest Itachi’s body. But when Zetsu stands over Itachi and is about to take him, Itachi becomes conscious again, sees Sasuke’s dead body with both eyes missing and goes ballistic opening a new Sharingan in the process and then disemboweling Zetsu.
Itachi now only lusts for Madara’s death. He decides to return to Root Anbu squad and fight along side Naruto to avenge his brother. He once again wears the Anbu mask to hide the fact that he is still alive and to avoid having to explain himself a million times that he was really an undercover agent this whole time in Akatsuki working for Anbu.
Together, with Kakashi, he fights Akatsuki and has an epic battle with the real leader of Akatsuki who turns out to be two seperate people playing the one part of Tobi; one Obito and one very old but still very strong Madara. This sets up a final battle between Naruto and the seemingly immortal Pain.
Sorry it took so long to post this. I’ve had it written forever and I know a couple of you asked about it but I just totally forgot. @_@
