Hi, before I begin chapter five I think a quick Predator biology lesson is in order. In the comics it was revealed that Predators have a gland located between their neck and collarbone which secretes powerful hormones into their bloodstream and which drives them to hyper-aggression. When this gland is over-stimulated, it sends the creatures into a frenzied rage, causing them to attempt killing any living thing in sight. Naruto has developed something similar and that will be the cause of his rampage. Right well let's go.

Deep within the seal, the Kyuubi raged. Whatever the boy had been exposed too was not stopping. His coils were decaying constantly and it was only the Kyuubi's charkra that was stopping it, this wasn't an act of kindness but part of a greater plan to escape. If the Kyuubi healed him of whatever was wrong it could then act like an ally and trick the boy into releasing it. The plan was perfect, or at least it seemed to be to the ancient mass of sentient charkra.

Hahaha, soon I'll be free and then I will have vengeance Madara, mark my words" The Kyuubi roared to no-one as it forced as much of its charkra into its host as possible.

Naruto felt the heat and anger rise up from deep within him, he didn't really know what would cause it. Was it part of his mutations or the actions of the demon sealed within him? He was leaning towards the latter as the scientists got scared whenever it happened around them. As he ignored it and waited for the guards to reach his cell he wondered what it would be, killing more prisoner in the training hall, more experiments in the lab or was he going to the fake village again to run a simulated mission? It didn't really matter. He'd complete it and then sleep off the anger. As the guards reached the cell door something was wrong. His vision was changing, slipping into the infrared spectrum. That should only happen if he wanted it to. He felt tired. The heat was getting worse, he was sweating now and struggling to breath. What was wrong with him.

"The scientists!" He growled. "Put something in my food, or in the air. Making me weak. Easier to control. Easier to kill. No, no, no... NO!"

Toruné watched the boy fall to his knees, mumbling things. It seemed the Kyuubi was trying to fix his coils. Great, that means the boy will be aggressive and unstable. The mission just got even harder. However Danzō ordered it done and Toruné would see it completed. Just as he opened the cell door Naruto let out an inhuman roar, which sounded like the word no, flooded the corridor with Killing Intent and attacked.

Naruto struck Toruné with all the force of a freight train. Toruné was left disoriented and vulnerable to attack. Something Naruto did. He began to pound away on the man's face. His fist quickly reducing the man's skull and brain to paste. He then launched himself at one of the agents who had moved to pull him off Toruné. He punched, kicked clawed and bit anything that got within range. Quickly Naruto was the only one alive. He remained for less than a moment before running off to find more of those that he thought, correctly, wanted him dead.

Hojo was beginning to get annoyed. Those idiotic drones had gone off to get the brat almost ten minutes ago and still had not returned. Danzo had decided to vacate this lab and move everything to a more secure facility to the east. The most competent of Hojo's assistants had been sent to oversee the assembly of the labs there. Hojo himself intended to oversee the transfer of the 'Liquid' and the boy's body personally. The man Danzo had in charge of studying the weapons was already on his way with the most of the tech, he had left the bomb-gauntlets and the damaged weapons for his assistants to transport along with the research notes later. Hojo had no idea why Danzo kept those things around, the level of destruction one had caused when they tested them in the countryside was on a scale Hojo struggled to truly imagine. Over three square miles reduced to wasteland with a single blast. Dr. J had called for the destruction or at least dumping of the bombs after that, it was the only time Hojo ever agreed with the annoying little man. Hojo turned as he heard footsteps coming up the tunnel from the holding area.

"About time, what kept you useless little..." the rant died in Hojo mouth as he caught sight of the boy, fists and mouth stained with blood, focus on him. Now Hojo was an incredibly smart man, his genius rivalled Orochimaru's in certain areas, and so his reaction should surprise no-one. He ran! Screaming out for the remaining ROOT agents to protect him. And protect him they did. However these ninja had been present when Danzo gave the order to avoid damaging Naruto's body, this meant they had to hold back and so were left at a distant disadvantage against the rampaging pre-teen. One of the ninja activated the facility's lockdown to prevent Naruto's escape. This also meant that none of the remaining scientists could escape. Once the screams of panic turned into screams of agony, Hojo know the ninja were dead. The boy was now attacking the scientists that were locked in with him. Hojo took off running as fast as he could, hoping to find one of the intelligent ROOT members. If he could then they could escape. In his panic he ran about aimlessly. Ducking and diving to avoid drawing the boy's attention.

The screaming stopped eventually. Either the boy was dead or everyone else was. Hojo knew which one was more likely. Drip, drip, drip. Hojo turned and continued to run. He needed somewhere to hide, to hold-up until Danzo sent troops to investigate where everyone was.

"There." Hojo huffed as he spotted a large door with a very large lock on it. As he struggled to remember the code a voice rang out behind him

"The code is 27 – 09 -1103. You know, the date of Konoha's founding"

Naruto struggled to his feet. His arms and legs felt heavy. He had a terrible pain in his neck and a burning sensation in his gut, over the seal. Just as he managed to get upright his legs slipped out from under him. He looked down and saw red. The entire floor was covered in red. It took him a moment to realise that it was blood.

"What happened?" He wondered aloud. "What did I do?" He looked at the chunks of, what most of once been people, and felt... nothing really. There seemed to have been a fight, they died and he live. Making it a good fight in Naruto's opinion. Listening Naruto heard someone moving up ahead.

"Right, find a way out of here. Then what?" Naruto mused as he set off down the tunnel. "Oh, what have we here?"

Naruto stopped as he spotted the man he hated almost as much as Danzo. Hojo, the bastard who oversaw the experiments on him. The man was franticly trying to open a sealed door. It was a blood seal, a pretty advanced one. You entered a code and then smeared some of your blood across the seal. If the code was right and the blood was keyed into the seal the door open. If not then an alarm would sound and the door lock up until an even longer code and accepted blood was used. Naruto smiled before calling out.

"The code is 27 – 09 -1103. You know, the date of Konoha's founding"

Hojo twisted around so quickly that he lost his footing and fell over. Naruto laughed and smiled at the pure panic and fear in the man's eyes. That look, begging for mercy with one's eyes. The one Naruto had on his face every time they strapped him to the table. That was what he wanted to see, that was why he had announced his presence. He wanted, no needed, to see it on the face of the man that had caused him so much agony. Hojo had just enough time to realise that his creation was about to kill him before Naruto fell on him, even more vicious then when he was rampaging.

When he had released on his pent up aggression, Naruto typed in the code and swiped some of Hojo's blood across the seal. As the doors opened Naruto saw that he was in the entrance chamber of Danzo's little lair. Creates were stacked up around the opposite doors. Opening the first create he reached, Naruto found it was full of small metal sticks. Naruto recognised them as the collapsible spear like bo-staffs. (Man-made Combi-Staffs). He grabbed one and moved to the next batch of creates. Here he found the claw-gauntlets (Man-made Wrist-Blades) he enjoyed using, taking two he moved on. The next few creates had nothing he could use. The final create held three gauntlets. They appeared ancient and had tribal etchings on them. He picked one up and examined it. Several red-lights lit up as he pushed one of the buttons. A sudden sensation swept over him and Naruto nearly dropped the gauntlet when he saw his hands had disappeared. He pushed the button again and reappeared. Smiling he removed the adjustable fitting from one of the claw-gauntlets and attached it to the cloaking one. Naruto wondered what these things were when his eyes shot open.

"Shit, shit shit." He swore over and over. "These things explode" He looked down at the panel on the gauntlet again and realised that it had more than one button on it. "These things have several uses! Danzo only knows about them being bombs." Naruto smiled. He went to the door and shut down the lockdown. He'd seen Danzo enter his code once and knew it would work. Bit of Hojo's blood and he had his escape route. Naruto went back to one of the creates and got an ANBU mask, a dog. After putting it on he collected another wrist-gauntlet and began to slowly push each button in sequence. Eventually the gauntlet began beeping and the lights began to flicker. Naruto threw it as far as possible into the base and ran up the exit tunnel as fast as he could.

Even after he reached the surface Naruto kept running. He didn't stop until the ground shook and collapsed behind him. He turned to look at the crater that had formed. Naruto just stared in shock. It was huge. He snapped to attention when his enhanced senses detected people approaching. Naruto activated the cloaking device and began to climb a nearby tree to watch.

Not a minute later a large number of ANBU, standard ninja and even the Hokage arrived.

"What happened here?"

"Is it the Kyuubi? Is it back?

"Look at the size of that hole"

They continued on like that, Naruto watched and planned. Konoha was too strong to attack, if they could spare this many ninja this quickly and still feel their village was save then attacking them would be suicide. As much as he wanted revenge for how he was treated, now was not the time. He set off towards the village, even if attacking was a bad idea scouting was something he could still do.

Ten year old Sasuke walked towards the small apartment she lived in. The carer she had been with up until recently had died and now Sasuke had to care for herself. Not that it bothered her as she was a very independent child. It seemed weird for there not to be festivities on October 10th, like there had been when she was a little girl. The whole village use to celebrate the Forth Hokage's victory over the Kyuubi. Then about two months after her seventh birthday there had been a fire. Some children at one of the orphanages had died and the truth came out. The blonde orphan boy in her class at the academy was really the son of the village's greatest hero and the reason the monster was beaten. But with him dead then the Kyuubi would come back. Afterwards everyone had become afraid, especially round October. There had been a bit of panic a little while ago when that explosion went off but everyone calmed down when they saw no giant fox getting ready to attack.

"Fuck, what is this guy?"

"I don't know, just keep attacking."

"Ahh, damn it. Fang over fang justu"

The sounds of fighting reached Sasuke's ears and she rushed forward to see what was happening.

Naruto had been moving from roof top to roof top, wondering why there was no festival. As he prepared to head towards the village walls and make his escape a kunai shot up at him from the street. He dodged and landed facing three kids, more than likely genin based on their age and the headbands with Konoha's logo engraved on them. The central one, a girl with red facial tattoos and three puppies in front of her, had been the one to throw the kunai. To her left was a large boy with the character for food on his shirt and to her right was another boy who just seemed to be just average in every way. The three of them quickly fired more kunai, and several shuriken, at him. He dodged again, but one struck the cloak-gauntlet causing it to short out. He growled when he reappeared and got ready to attack. He smirked at the looks of shock on their faces when he appeared. He most look a sight, covered in blood like he is.

"What the hell?" the heavy boy asked.

"He's not an ally, get him" the girl ordered.

As they rushed Naruto tensed his arm, releasing the blades in his gauntlet. Who a low roar he charged them intending to kill them quickly and flee. The genin soon learned that even though they looked about the same age as their opponent, they were seriously outclassed. One punch and the average looking guy was out of the fight with cracked ribs.

"Fuck, what is this guy?" Exclaimed the heavy boy as he attacked from the right.

"I don't know, just keep attacking." Called the girl as her and the puppies rushed from the right. Naruto growled again and dodged her attacks. He quickly turned and lashed out at the heavy boy with his wrist-blades. He would have opened the boy's throat if the girl hadn't knocked him out of the way. Receiving a nasty gash on the upper of her right arm.

"Ahh, damn it. Fang over fang justu" She called before launching herself at him, rotating at high speeds.

"Shit" he yelped as he dodged. He ran after her and when the justu ended he struck her on the jaw leaving her dazed. He turned just in time to avoid the fat boy's sneak attack and kicked out at the back of the boy's knee. A loud crack and the boy was down. He turned to the girl to see her beginning to recover, her pets having gathered between like some kind of barrier. Naruto's laugh was cut short by a kunai just missing his face and then a foot the the side of his face.

Sasuke arrived just in time to see a green blur strike into something that became a red blur. The green blur seemed to be a jonin of Konoha. The red blur turned out to be a boy, he looked about thirteen, wearing tattered pants and a heavily creaked ANBU dog mask. Both were stained dark red, as was the rest of the boy. The boy looked like he had been dunked in blood. The boy snarled and then touched something on one of the large gauntlets he was wearing, swore and slapped the gauntlet. The next thing Sasuke knew he was gone. Coughing caught her attention and she turned to see a boy spitting out blood and holding his chest.

"Who the hell was that?" A girl from the Inuzuka clan cxclaimed.

Right, Naruto is lose and off to find his roots. Well what did you think, first real time describing a fight scene so feedback there would be nice. As usual let me know if you spot any grammar/spelling mistakes or you have an idea for a fight Naruto can get into between now and the Wave Mission.

Thanks again for reading.
