Eren of the Sharingan
Eren's parents lay at his feet, blood flowing from their chests. 'You must' wheezed his farther 'overthrow Danzo and his ANBU section. He is responsible for the corruption of the Leaf village!' We gave you a gift' said his mother in a similar state 'an eye belonging to the Uchiha clan, it is strong it gave you great power, use it well because one day you will kill Danzo with that eye. He parents died and Eren promised to avenge his parent's death. Eren's parents ran a group that protested about Danzo the 5th hokage. They said he made the village suit only his needs and cared only for himself. Lord Jirayia and Naruto Uzumaki (host of the nine tailed fox) went looking for lady Tsunade to be the 5th Hokage, but Jiryia was taken by Orochimaru and Tsunade was killed on the way back to the village. Naruto was sold to the akasuki. No one really knows what they did to him but they expect that they extracted the nine tails from him. Only shizune and tonton escaped and they started the rebel against Danzo.
Eren's Dad fought in the 3rd shinobi war and have taken eyes his Uchiha friend who was killed. His Dad took his eyes and with the help of a medic had the sharingan eyes put in to replace his. He gave him the finishing blow and that unlocked the mangekyo. He gave Eren one of his eyes when he became a Genin. His dad taught him how to use it and warned him of the consequences of over using it. He learned how to use fire style and then could use Amaterasu (amazing progress for a child of 13) and with it made chunin with ease. He surpassed his team mates quickly. His teacher taught his how to use his families lightning style chakra. Eren was 16 when Danzo's ANBU came for his parents they fought back Eren kill 4 of them but was thrown aside and the ANBU kill his Mum and Dad. The ANBU left before they had noticed they had not killed Eren. That same night he took his dads eye, packed his bag and left the village knowing that he would not be allowed back after killing 4 ANBU members and fighting against the Hokage in a communist driven group. He loved his team especially Mika. He said they would be together one day but when he thought about what he had done he realized that could never be.
As he drew closer to the village gate he thought 'this is like when that Sasuke Uchiha left just after Danzo became Hokage. I wonder if we will ever meet.' Where will I go? I will not be accepted back into any village in the Land of fire let alone the alliance.' 'STOP!' Yelled two jonin shinobi who blocked Eren's path. 'We will not lose another shinobi to Orochimaru especially one who possesses a sharingan!' A trail of blood came from Eren's eye. 'Amaterasu!' he said in a loud whisper the two jonin screamed as black flames consumed them. They tried to put them out but was useless. Eren walked passed their scorched corpses and walked through the village gate. 'I don't think I want to go to Orochimaru after I heard what his goals are' he said.
