Metal Naruto.

Ok, now with this one there have already been a couple other authors who have done it. It's a Naruto with the iron sand ability, but also with steel release and the magnetic jutsu as well. Now in this, its not some random gift from Kyuubi, but a incomplete bloodline gene. Basically, it allows for an elemental bloodline, but its incomplete, meaning it could create any kind of sub element within the person. now, Naruto will not simply be like gaara in this, and just let his iron sand fight for him. Oh no. in fact, he's more of a direct combat person because of it. Because he uses the iron sand to form into several different weapons during a fight. Of course Naruto will also be able to use it for defense, but due to how heavy iron sand is, he'll be rather slow is he were to use something like the iron sand version of Gaara's sand armor, though it would be much more powerful.

Naruto will be adept at using several different weapons, as his iron sand can take on any weapon he desires.

Naruto's personality will mostly be that of Hiei from yuyu hakusho. And when it comes to people, he typically sees them as how useful they will be to him when he decides weather or not to kill them, or not. Thus its this mentality is when he saves Mikoto from being killed during the Uchiha massacre, as with Fugaku dead she would be clan head.

This would also happen during the wave mission, as he would keep Haku (and possibly zabuza) alive, due to their power and abilities, and would take them as his surbordinates, or something.

Naruto's affinities:

Fire, lightning, and earth, as I believe earth+lightning is what makes magnetism/iron sand.

Kinton (metal release) Daijiton: Grand/Great Magnet Release

He can also take the iron out of a persons blood and add it to his own iron sand, which leads to his metal having a blood like color to it.

Harem members:

Fem gaara (akaihime)- when naruto's abilities with iron sand are found out, Sarutobi takes Naruto with him to Suna in an attempt to negotiate the 4th kazekage to help Naruto train his abilities. He eventually meets the by now crazed fem gaara who tries to kill him, thinking that with his iron sand ability he was trained by her father to try and kill her, due to iron sand/gold dust being effective against shukaku's sand.

Fem shukaku. Now with this, she isn't really crazy, she just has a major inferiority complex because she is the one tail, and seen as the weakest. She would constantly try to fight so her strength would be recognized, and not bee seen as weak, but comes off as crazy and bloodthirsty.

Fem Kyuubi- in this, she is rather bloodthirsty, and has a bit of a blood fetish, so when Naruto kills a lot of people and takes the iron from their blood to add to his own, which leads her to like Naruto a lot more than other humans.

Pakura (optional)

Mikoto uchiha (optional)

Fem itachi (Mikoto and Kushina had decided to do an arranged marriage between their children because of their close friendship so on that female Itachi would be pretty close to Naruto when protecting him along with spairing Mikoto from the massacure since she had no part in it.)

Optional-

If you want, you can have Naruto get into machinery, and robots if you wish. And I recommend giving Naruto a summoning contract where the summon creatures are actually machines/animals turned machines, hell even giant robots for all I care. (Gundam, gurren lagan, etc) or a Raijuu summoning contract.

Raijuu:

A legendary creature from Japanese mythology. Its body is composed of lightning/ and or fire and may be in the shape of a cat, fox, weasel, or wolf. The form of a white and blue wolf (or even a wolf wrapped in lightning) is also common. It may also fly about as a ball of lightning (in fact, the creature may be an attempt to explain the phenomenon of lightning). Its cry sounds like thunder.

Raijuu abilities:

Electricity/fire manipulation

Electricity/fire mimicry

Enhanced agility, bite, durability, endurance, flexibility, jump, senses, speed, strength

Flight

Canine/feline physiology

Night vision

Mustelid (weasels, badgers, wolverines) physiology

Simian physiology

Enhanced combat

Prehensile tail (a tail that can be used to grasp objects)

Other than all that, do whatever.

PM if interested, as well as for techniques and such that were created for Naruto to use in this.
