Haku, Zabuza and Team 7 fanfic.
Chapter one

The battlefield was dark, bloody, cold and strangely... completely silent. Reguardless of the amount of shinobi slaughtered upon it, not a sound could be heard. A tall figure in a very long coat observed this..he thought it strange.. intrigued, he continued to run forward,noting that there were needles stabbed into the victim's bodies. No way...It couldn't be.....Impossible..Believe it! They were supposed to be dead...he saw them die...he thought to himself. As the figure proceeded, a freezing mist surrounded him, forcing him to retreat.

'..There's only way I can be certain that it's really them.'the figure muttered softly 'I'll have to be able to sense their chakras'....The figure considered for a few seconds..and then drew out a giant scroll.....which means.....I'll have to .....'

Meanwhile, a group of Shinobi were trapped in the deadly mist and were cautiously trying to evade needle based attacks. These Shinobi had faced this specific enemy long ago...so the group understood how their attacks worked....
'Kakashi sensei, watch out, he's heading for you now...CHAAAAAA!' this voice belonged to Sakura, the kunochi of the team who then slammed her fist into the ground, creating a massive hole in the ground and forcing the enemy to fly backwards.
'Good Work, there Sakura' smiled Kakashi..
'We're not out of the woods yet...'a firm voice from behind Kakashi stated..'Kakashi...'Sasuke Uchiha activated his Mankekyo Sharigan and a purple light and a horrible skeleton looking creature appeared- this was his susanoo.
'You're right...Sasuke.....' the grey haired Jounin uncovered his sharigan eye, like Sasuke activated his Mankekyo and got out a kunai knife from his pocket.
"Kamui!" he yelled....but it was too late- Kakashi felt a searing pain in his arm caused by the sting of a needle. Kakashi yelled out in pain and gasped for breath and fell foward.
"Kakashi-sensei!" yelled Sakura who immediately started healing Kakashi with her medical ninjutsu.
"Watch out, the both of you!" exclaimed Sasuke..
Needles darted towards the group at a lightning speed then pieces of ice appeared at the same speed as the needles. Then the trio realized that these attacks were being used by a young shinobi, who was right above them...He was brown eyed and very femine looking, despite being a teenage boy..and...he had dark long hair which was tied into a bun.
Kakashi, Sasuke and Sakura gasped in horror- No way...that couldn't be... Surely it wasn't...
BANG! The figure fell and crashed into the ground from the impact of the punch from a shadow above. A figure with bandages over his mouth then walked up to the fallen figure and looked at it in shock. 'Haku...'Haku opened his brown eyes "I'm fine, Master Zabuza...'
"I knew it...I..knew those chakras I sensed had to belong to you guys...I just didn't want to believe it...Believe it....!
The voice was the voice of the shadow who had punched Haku...It was the voice of a boy who's voice was breaking, a adolescent's voice -yet it had great authority, determination, and confidence in it....and the usage of the phrase 'Believe it'...
Zabuza and Haku exchanged glances.....It couldn't be....no way....
