Naruto was growling as he stood under the enormous statue of the First Hokage, Hashirama Senju. He faced the other side of the Valley of the End at a person who stood under the equally enormous statue of the greatest of the Uchiha Clan, Madara Uchiha. The person under this statue was none other than Sasuke Uchiha, Naruto's best friend, but Sasuke wasn't the same as Naruto remembered, he was twisted by the power given to him by Orochimaru, the Snake Sanin of the Leaf Village, Konoha.
Sasuke laughed darkly as he gazed upon he once best friend, Naruto was in his same 'kill me orange' jumpsuit, his blonde hair spiked in every direction, his blue eyes glaring back at Sasuke and his three whisker marks more defined and feral along with his canines then they usually are. Sasuke was surprised when Naruto had unleashed this strange power that took the form of an aura around Naruto with a single tail.
Sasuke laughed some more as the curse mark spread over his entire body turning his skin dark and making a black shuriken-like mark across his nose and his eyes turned black causing his now fully matured Sharingan to stand out much more. Suddenly the back of Sasuke's blue shirt with the Uchiha symbol on the back stretched and tore revealing to hand-like wings he kneeled a bit as he adjusted to the weight of the wings, dirtying his white baggy shorts in the process. A few seconds after he stood up and charged a Chidori in his right hand which became tainted by the curse mark forming a Dark Chidori.
Meanwhile, Naruto had formed a Tailed Rasengan (A/N: This is just what I call the Rasengan Naruto forms when he's in the 1-tailed state) and the two leaped outwards towards each other. They shouted each other's names, 'SASUKE!' 'NARUTO!' As the two attacks collided, Naruto felt an immense pain but not where Sasuke was striking, but rather in his eyes. Soon after, Sasuke and Naruto were enveloped in a huge black sphere that blocked the waterfall between the statues of Hashirama and Madara. The sphere dissolved and exploded, sending the two flying towards the bottom of the Valley.
When all of the dust and mist had cleared, Sasuke was standing, in the rain, over a beaten Naruto, who had a hole in his stomach from where Sasuke had stabbed him with his Dark Chidori, though luckily he missed any vital organs and missed his spine completely. Sasuke then fell to his knees and leaned over Naruto with his hands holding him up as he gazed upon Naruto's face in a daze. Suddenly Naruto's eyes shot open for a few seconds as he struggled to stay conscious but he fell back into unconsciousness and Sasuke gasped before falling down beside Naruto.
Just before Sasuke lost consciousness, his last thoughts before he passed out were, 'what was that?' A few moments later Kakashi Hatake arrived and examined the two before sighing in relief, picking both of them up and carrying them back to Konoha. When Kakashi arrived, the Fifth Hokage, Tsunade Senju, came up and inspected both Leaf Genin before placing them in the hospital, however, she was disturbed by what she saw with Naruto, but decided to mention it later, after he recovered from the intensive surgery he would need.
