3 Bell Test

"So, you have until noon. Come at me with the intent to kill."

As soon as Kakashi said it, Naruto ran towards him with a kunai, full of bloodlust. 

Since there was no Teuchi, there was no one who saved him before he passed out from starvation, and only a kind woman delivered him to the hospital, where Hokage gave him an apartment. 

So, in this universe, he completely lost trust in the world, especially since it was revealed that he was actually someone important, the container of the Kyuubi. How could he be left to starve?

And now, he was give an ass of a teacher who said that only two people will become a ninja. And he was the deadlast among them. It was obvious! Kakashi didn't want him on his team!

So he will make him. 

He made a thousand shadow clones, and sent some to transform as trees and stuff, and took out kunais and shurikens that had his transformed clones mixed in them.

His eye turned into slits, and he got a slight layer of red, corrosive chakra as his speed and strength skyrocketed, and he aimed for both Kakashi's life and his bells. 

Sasuke and Sakura were shell-shocked by what was happening, and even Kakashi was shocked at how Naruto was using Kyubi's chakra already. He engaged in a taijutsu spar, but the red corrosive chakra actually burnt his clothes and skin. 

"You don't want me in your team!? So die!"

And Naruto drew out more of Kyubi's chakra, attacking Kakashi relentlessly as he avoided every attacks after the first burn and used his kicks to pop out clones, which has almost burnt away the soles of his shinobi sandals. 

Naruto himself didn't realise that his skin was peeling off from himself. He was in too much rage to notice that. 

Kakashi noticed this, and felt that this is becoming more dangerous than he thought. He could of course defeat Naruto, because he wasn't even in 1 tails chakra cloak, but not without hurting him. 

So he decided that it is the time to stop this. He pulled out his headband, revealing a 3 tomoe Sharingan. 

Sasuke was shocked to see it, who was watching everything from a distance. 

First that loser and than this? Just what is happening anymore!?

Kakashi's Sharingan spun, and he used a slight sleeping genjutsu. 

Naruto fell asleep immediately, and Kyuubi's chakra dissipated. But Naruto's whole skin had turned red, like it had burned off. And almost instantaneously, his skin started healing with incredible speed, almost as if he had a regenerative factor like the First Hokage. 

But that wasn't the time to think about that. Kakashi immediately lifted Naruto in his arms, and headed to the hospital. But he made sure to leave behind a Shadow Clone to explain things to his other two genins. 

Bell test could wait, the situation was much more serious than he thought. Third Hokage, just what had been you doing!?
