Naruto looked at the undead horde drawing closer to him. Normally he'd have retreated by now, try and find somewhere safe, but he was the last line of defense. Beyond him were only the injured and civilians that had survived. So many had fallen to this undead legion adding to their ranks constantly with the fresh newly dead members, the living only fell to join them. Already Naruto had faced and killed his own teammates, many of the others that had graduated with him. Every day since this outbreak had been a living nightmare as thousands upon thousands of those zombies continued attacking.
Crossing his fingers, he began summoning his chakra to utilize the best method he found to take care of the legions of undead so far. Swarms of Naruto's sprang forth from the ether to charge at the legions of undead minions coming at him. Each pair formed a rasengan in the right hand of the lead member, who would slam the ball of swirling chakra into the heads of the zombies, splattering the area with the remains of the mental organs and dropping the undead abominations.
As always, he kept a few back to defend himself as he continuously summoned clones to replace those that fell. This was going to be the final stand, he knew this, but every second he could buy the others would be worth it because he was buying them the time needed to develop a way to remove the zombies forever.
He was running short on his own chakra reserves already, and was feeling the draw of Kyuubi's chakra hanging just at the outer edge of his consciousness. He knew that if he surrendered, he wouldn't stop until everything was dead.
Feeling his anger building at the situation, he snarled fiercely at the scenario. They just wouldn't stop coming, it wasn't fair! Damn that Orochimaru for causing this. Damn him back to hell from where he spawned! The chakra cloak began forming around him, as a roar of rage ripped from his throat. If he was going down, he was going to take all of them with him.
A tail swung back to close the cave opening behind him, sealing the others from him and the zombies; leaving him the last living thing on the surface. With a snarl, he turned towards the undead hordes and surged forth, ripping through the legions of zombies in a bloody massacre.
