The Chunnin exam was going fine for Naruto, now he has been Hokage for 10 years. They had just finished the forest phase and for Naruto's first time he had to eliminate some people like his first Chunnin exam. There was a kid who had appeared out of nowhere but had a real headband of a shinobi, a village he didn't know about, so Naruto had his eye on.
His name was Redlion but his real name was Mark. He new he could win with his new techniques; unlike Naruto and Sasuke he had a rare bloodline trait that he used to copy Sasuke's Sharingan. Then copied the Chidori, Rassengan, and Lee's speed and a double lotus as well as copied Sakura's strength. Although he was strong he new he only had about 7 years to kill Naruto, Lee, Sakura, and Gaara plus their friends. He only had 7 years because of how fast he learned these techniques and how he learned them. Redlion's opponent was Lee's son who was just as fast as Lee was when he was in the exam.
As their battle started they were matched but as it progressed Lee's son Jake ended up using his lotus. When that happened Lion used his at a level higher which just murdered Jake with amazing speed. Lion had the will and instinct to kill though but luckily Lee and Naruto stopped him. This made Naruto very curious as to how strong this kid really was; he and Lee had to calm down the kid before they could do anything.
After that match most everything was fine but Naruto knew he had to put the strongest person against Lion or he could kill them very fast without any flinching. His headstrongness made him want to go against him but then it would be too unfair. He had to choose a genin who passed the preliminaries to do it. He chose a 5 year genin shinobi from the leaf village named Caren, though strong she was very smart and good at chakra control. She had the strength of Sakura that is what he planned on. She would have to get one hit on him but after that he would be dead.
That's not what happened though like before he went headlong and just over powered her as well as destroyed half the whole wall. This astonished Naruto to no end next Lion would have to face what was the underdog who didn't care. Of course the match ended with one hit by a Chidori! Naruto was amazed and scared a little.
At last it was the last match which Naruto had taught Lion's opponent the rassengan which meant that he would probably lose, which naruto was hoping. Which didn't happen even with the last berserk type mode and the ressengan he'd lost. Naruto couldn't take it so he jumped down and started making a ressengan and charged after Lion!
