—Uchiha Savior—
Betrayal of the Jinchuuriki
Naruto gives into the darkness surrounding him as a child. He grows to despise Konoha and all it stands for. Naruto plans to one day destroy it completely, until then he's going to act like a faithful ninja of the village. He keeps to himself as the social outcast as he patiently waits and trains for that day of destruction.
The Uchiha aren't massacred because they make a deal with Danzo to support him should he become Hokage. Following an assassination attempt on the Sandaime Hokage by Kumogakure ninja fanatics after the botched Hinata capture, Danzo gets appointed by the Fire Daimyou. Danzo had used Shisui's Sharingan eye on the Daimyou to trick him into thinking the Sandaime Hokage had grown complacent in his old age. Danzo launches an immediate attack on Kumo. The skirmish is short, bloody, and effective, securing Konoha's place as a very dangerous 'new' village.
Sasuke grows up with love, admiration, and natural skill. He constantly compares his achievements to Itachi in hopes of one day surpassing his brother in terms of power, skill, and ability. He quickly becomes the most promising and well-liked genin of his year. When his Academy Exams come, he passes and gets partnered with Naruto and Tenten (Sakura and Lee didn't perform to Danzo's new standards and Tenten's team was reorganized after losing two members). They are able to pass their Genin Final Exam and become regular shinobi. Despite their numerous differences, both Naruto and Sasuke develop feelings for Tenten and frequently butt heads over her. Tenten, though suspecting their feelings, tries to discourage them about getting into a relationship with her because she's not a native Konoha-nin and will bring bad karma upon them.
After several missions (including three C-turned-A ranked missions), they get enrolled into the Chuunin Exam. Through luck and skill, they are able to get all the way to the Final Exam. However, during the Second Exam, Orochimaru ambushes them in the Forest of Death. Though he fails to brand Sasuke with the Curse Seal (thanks to Kawarimi), he was able to attract Naruto's interest of attaining greater power in a hurry by promising to teach him how to control the power of the Kyuubi no Kitsune inside him.
Naruto abandons Konoha to seek training by Orochimaru to control the Kyuubi so that he can later destroy Konoha to satisfy his hatred of it.
Sasuke gets apprenticed to Jiraiya after he expresses his desire to bring Naruto back to Konoha. Jiraiya teaches Sasuke numerous Yondaime attacks, including the Rasengan and Sasuke later creates both a Katon and Raiton version.
Sakura becomes the new apprentice of Tsunade after she impresses her with her incredible chakra control, despite not being a ninja. Tsunade later teaches her how to use super strength to reinforce of her fighting style.
Though Tenten has grown to love Sasuke, she sees Naruto as a neglected little brother who's starving for affection so she grows equally as determined to bring him home as Sasuke is.
