Naruto: Space-Time Lord

At a forest, one could see a young boy with yellow hair kept transforming himself in different people: Iruka, Hiruzen, Sasuke, etc...

Then, a puff sounded in Naruto ears as he said "Shadow Clone no Jutsu'' five identical looking clones appeared, surrounding him, then, all of them began to practice Fuuinjutsu, this was the only thing that he never practiced in the future because Naruto wouldn't try to seal the Otsutsuki clan, only kill them, to this, he practiced many different fields such as Shurikenjutsu, Kenjutsu, Ninjutsu, Taijutsu, etc...

After a hour practicing Fuuinjutsu, the shadow clones dispersed, sending the knowledge directly to his mind, then, Naruto put his weights on as he could feel his body being pulled down but enduring it, punches were thrown at the tree for a unknown amount of time, after doing this until his body was full of sweat and his hands bleeding non-stop, his hands bones had thin cracks but Kurama healed it reluctantly.

This was something that even a crazy dude like Bushier Brows-sensei and Rock Lee couldn't do because they don't have a regeneration monstruous like that, this was something that Naruto did unconscious as it was the same training routine he did in the future, then, he did the same thing with the next activities, kicks, squats, push-ups and finally, running.

While Naruto trained like crazy, his Shadow Clones finished the Fuuinjutsu learning easily and began to refine chakra, this continued over a week as the Academy Graduation Exam was finally nearing, Naruto could now handle 350 KG of weight in both arms and both legs, not only this, his own Chakra Pool expanded many times.

What Naruto failed, rather, pretended that he wasn't able to notice that behind a tree, during the entire week was that a boy and a man in green colored clothing was observing him, the man said to the boy near him "Lee, you see this boy? He's Uzumaki Naruto, just from seeing this, I can see that his talent is simply too high, unparalleled, even with him being a genius, you see his hands? It isn't bleeding because of his regeneration but every time he finish his daily training, both hand and feet are bleeding and broke, Lee, this is... this is the Power of Youth!''

"Yes, Gai-sensei, I... I can feel that his Power of Youth is enormous, G-Gai-sensei!" Saying this, both boy and man began to cry as a pool of tears were formed under them.

Konoha, Genin Academy

Naruto entered the room as many people began to stare at him, wondering who this boy is, there was, however, only three people that could identify him immediately, Shikamaru, Sasuke and Hinata, that seemed very happy that after the Academy gave them a time of one week to prepare to the Graduation Exam she was able to meet Naruto-kun again.

Iruka-sensei also entered the room and shouted "I will call a person per time to show if you have the qualifications to become a genin, first person: Sakura Haruno" then, a girl with pink hair walked to another room and returned rather quickly, seemingly proud.

This happened until Naruto time finally came, then, he entered the room where Iruka-sensei was sitting at the side of Mizuki, finally, Mizuki said "Naruto, show us your Transformation Jutsu and Clone Jutsu, if you do so, you will pass the Graduation Exam and officially become a Genin" but his inner thoughts were 'Hmph, as if this demon fox will be able to even do a Clone, heh, after I give the Forbidden Scroll to Lord Orochimaru, he will reward me, hahahaha'

Naruto said in a low voice as he did hand seals at astonishing speeds "Clone no Jutsu" and one clone appeared, then, after Iruka nodded, Naruto did more hand seals as his previous figure of about 5'0'' became 5'84'' and his appearence turned exactly like Iruka!

Iruka seemed to be really happy as tears of joy threatened to flow out of his eyes "Naruto, you managed to become a Ninja, congratulations! Here's your headband." Though Iruka calmed down and said with a calm tone, Naruto knew that he was very happy and would probably reward him with a ramen, hehe, it has been long since he had eaten at Ichiraku, now that he think about it... Ichiraku Ramen owner body never was found, in Naruto point of view, the seemingly ordinary man was very mysterious, hell, there's no way a ordinary man could possibly do a ramen this delicious!

Even though Naruto performance at the Graduation Exam was the best possible, his overall score was at the lowest rank, luckily, his team probably won't change.

Talking about his Doujutsu, Naruto finally thought about something 'My hair is yellow... meaning that my Namikaze bloodline is dominant over Uzumaki bloodline, there never had a case where a Uzumaki had a Doujutsu so probably it came from Namikaze, the question is, in the future, there wasn't any information about this clan, even my father parents were unheard of... very mysterious.'

Going back to his home, Naruto jumped at the bed and kept lying at it until he fell asleep, his previously a.d.u.l.t body could handle the strain of training for years while not shattering because of it being strained but now, being only a child, his body strain was quite high even though Naruto only trained for a week, anyway, putting his newly acquired headband in his head and looking at himself in the mirror, his hair now looked a little, just a little bit similar to Kakashi, he decided that this need to be fixed.
