Nine-Tailed Naruto Clone

A monstrous clone of Naruto Uzumaki created by Kabuto Yakushi's cellular snakes with chakra from Kurama mixed into his being.

Personality
The clone first appears to seem very animalistic and violent much like Naruto when under the influence of his Version 2 Chakra Cloak. While not fully explored, the clone seems to possess a distinct interest in Naruto, instinctively siphoning Kurama's chakra for before going on a rampage and readily attempting to kill him when locating him some time later.

Appearance
The clone appears nearly identical to Naruto's Version 2 chakra cloak with the exception of having dark red eyes and mouth with a darker shade of body. Once it siphoned enough of Kurama's chakra, the clone can temporarily transform into a gigantic replica of Kurama itself, though smaller in size and similar to that of Naruto's Tailed Beast Mode.

After a battle with the original Naruto who was in Sage Mode, the clone's Version 2 cloak had been stripped away, revealing a mutated version of Naruto, with darker skin and a single tail on his back that wasn't made of chakra.

Abilities
The clone possesses both impressive speed and strength, crossing the distance between itself and Sakura Haruno in an instant and then punching her a sizeable distance with a single blow, knocking her out. Likewise he was able to easily outstrip and overwhelm both Might Guy and Rock Lee in hand-to-hand combat, forcing master and student to counter by opening the Eight Gates. Even so the clone showed massive durability, as it was mostly undamaged by their barrage of enhanced-attacks. Like the original Version 2 state, it could create incredibly powerful shock waves with simple roars. Unlike the original Version 2 state that Naruto entered, the clone is fully mobile even without the skeletal structure.

After gaining more chakra from Kurama, it turns into a gigantic avatar of the fox. Like its original, it possess massive physical strength, enough to reduce large urban areas to rubble with a single swipe. It is also capable of using the Tailed Beast Ball. Oddly, unlike the original Kurama, the clone remains bipedal in motion. However after a short while, the clone's extra chakra reserves were exhausted and it regressed to its original state.

Chikara Arc
Kabuto Yakushi managed to implant a swarm of his cellular snakes into Naruto, with Kurama's attempt to purge the foreign entities only adding its chakra into the material they were recreating. When the snakes were 'ripe', they began paralysing Naruto while he was fighting Kabuto's reanimated Ninjas. But Miina, who somehow knew of their presence within Naruto's body prior to the attack, used her abilities to aid him in expelling the creatures.

But once the snakes were vomited out, they formed a clone of Naruto in his Version 2 State. Kabuto attempted to take control of the creature, only to retreat when the clone proves to be too powerful to fall under his influence. The Naruto Clone then proceeded to knock out Sakura Haruno in one punch before viciously attacking his genetic parent as Kabuto attempted to control the clone from afar.

By then, Kakashi Hatake, Team Guy, Team Kurenai, and Team Asuma arrive to aid Naruto and Sakura. The clone fights effectively Might Guy and Rock Lee, until both open several chakra gates and manage to repel yet unable to damage him. Despite Hinata Hyūga's interference, the clone grabs Naruto to siphon Kurama's chakra, enlarging into more Kurama-like form. In his new form, the clone runs amok, destroying great portions of the village and the mountains around by shooting a Tailed Beast Ball. After Kabuto abducts Naruto and Dokku when he was about to squash them, the Naruto clone reverts to his original size before being captured by one of Kabuto's snakes.

He also revealed later during the summoning of the tower, surprised when Naruto on his Sage Mode, beats him repeatedly. As the tower top collapses, he fell along with the floor, but returns as a Hydra-like creature.
