I do not own Naruto or any of the characters. This is a challenge I was given recently. I will update my other stories but not yet. If you want a certain story updated, pester me about it and I will get it done. Give me an angry PM about me not updating whichever story and I'll get to it. :) This chapter is the same as the episode(mostly) until Haku falls.

Change

Naruto stared in shock at Sasuke. Haku had been pelting them from all sides with Senbon and Sasuke had shielded Naruto from an attack. Now he was laying on the ground, dead. Red chakra began swirling around Naruto. He began to shake as his anger boiled into fury. He looked up at Haku and Haku could see that his eyes were now blood red with slit pupils. The sight of the eyes alone terrified him even though he wasn't sure why.

"I'm gonna kill you," Naruto said his voice slightly closer to a growl than before.

As the chakra continued to swirl, the face of a fox with red eyes formed over Naruto and the senbon stuck in his back were forced out. Then his injuries healed producing some steam. His fingernails grew into claws, the lines on his face thickened, his hair grew thicker and messier, and his teeth became pointed. The fox head disappeared and the chakra finally settled a bit but remained visible in a swirling ring about six inches high around Naruto. Then he turned toward Haku and began to move toward him.

Haku threw three senbon at him but he produced a feral roar and chakra shot forward and knocked the senbon out of the air. Naruto continued but Haku suddenly disappeared and reappeared behind him.

"His chakra grows stronger every second," Haku said to himself. "I must strike now!"

His image was suddenly displayed in every mirror and all of him threw senbon. The senbon hit their target and stuck in Naruto's back and shoulders. But Naruto simply roared even louder and the senbon shot out of him as chakra shot out and into the mirrors along with gale-force winds. The wind was so strong that Haku couldn't move and was stuck in one mirror. Naruto instantly charged at him and smashed the mirror but Haku managed to avoid the punch. As Naruto was landing, Haku appeared from a mirror shard and fell at Naruto with a senbon ready to stab him.

At the last second, Naruto suddenly shot sideways and flipped multiple times landing on his feet and one hand and slid a few feet before looking over at Haku. Haku fled toward a mirror but Naruto grabbed his arm. He then began releasing so much chakra that Haku couldn't do anything at all, even focus his own. Then Naruto focused chakra into his fist and smashed it into Haku's mask. Haku shot away and smashed through a mirror then bounced off of his mask and rolled a good fifty feet before stopping. His mask was heavily cracked and all of his mirrors shattered.

Haku stood and his mask began to fall away. Naruto charged and leapt into the air to finish Haku off as the last piece of mask fell, revealing his face. Then, Naruto stopped, his fist mere inches away from killing Haku. Naruto's eyes had returned to normal and he was panting heavily from using so much energy but didn't seem tired otherwise.

"So, that guy in the woods," Naruto said. "That was you?"

"Why do you not strike?" Haku asked. "Did you not just vow to avenge your comrade's death by killing me? Or was that vow just empty words?"

Naruto clenched his fist harder and pulled back a bit growling then smashed his fist into Haku's face. Haku stumbled back then fell. He landed hard and waited for the next strike but it never came. Naruto was distracted by something. His eyes were normal and so her the lines on his face and his hair but his fingernails and teeth had stayed the same. Naruto had only noticed when his claws had cut into his palm when he punched Haku. Just then, Kakashi dashed forward to finish Zabuza. Haku created two mirrors, one by himself and the other in front of Zabuza. Then he stepped into the closest and into the path of Kakashi's attack. Kakashi impaled him then stumbled back.

"I'm sorry Master," Haku said. "I failed."

Zabuza stared in shock as Haku fell and died then looked at Kakashi.

"I..."Zabuza said.

"Now you die," Kakashi said.

"Wait," Zabuza said. "Give me a knife. Let me atone for as much as I can."

He somehow managed to break the bandage around his neck and mouth with his teeth then the rest fell away. Naruto tossed him a kunai and he caught it in his mouth. Then he turned toward Gato. Gato turned and retreated behind his forces. Zabuza charged forward and began cutting his way through the mercenaries with the kunai. About halfway there, several mercenaries managed to drive their weapons into his back. He kept moving and smashed his way through the rest of the mercenaries then charged forward and spun slashing Gato's throat with the kunai. Then the rest of the soldiers drove their weapons into his back.

Then, Zabuza collapsed and Naruto and Kakashi both created several clones, Kakashi making several hundred, and the last of the mercenaries turned and dove into the water in full retreat. Naruto smiled at their fear then looked back at his claws.

After a short while resting in the village, they headed back to Konoha. When they arrived, the Konoha 11 met them and welcomed them back happily. Hinata was just as shy as ever, of course, but the others cheered and patted them on the back and no one noticed Naruto's claws or fangs because Naruto kept his mouth closed and his fists clenched. When Naruto got back to his apartment he sat on his bed and held his claws up in front of his face.

"What the heck happened to me?" Naruto asked himself. "Maybe I could ask the Third. Or Kiba. He and his clan know a lot about canines of most kinds."

There was another option but he didn't feel like trying that yet. So, he rested for a few minutes, then he got up and headed for the Inuzuka house.
