Lovel, Uchiha.

Before reading some notes:
- Got permission from Mizukage to create this. Still have to change my last name on my application to 'Uchiha' though, but for some reason I cannot edit my application.
- All the Jutsu descriptions are from Leafninja.com, thus I did not create the descriptions. Also, the Jutsu are the standard jutsu of this clan. Automatically learned after obtaining another Sharingan Stage. They are at the bottom of this template.
- The Sharingan Stages Requirements are under the Sharingan Stages Information.
--------------------------------------
Kekkei Genkai Name: Uchiha Clan.
Description:

Clan:
The Uchiha Clan is a clan that possesses a Doujutsu (Eye Ability) called the 'Sharingan'. Although only some of the Uchiha Clan have the ability to activate that.
The clan is also said to be descended from the Hyuuga Clan, which possesses the Eye Ability 'Byakugan'. Because of the bloodline possessed, the Uchiha Clan is excelled at being to read and fend off attackers.

Doujutsu:
Doujutsu. The Sharingan gives the ability to read Genjutsu, Taijutsu and Ninjutsu then defeat them. This Sharingan can also copy techniques, but the user must be able to read the opponent's handseal speed, also, cannot copy the jutsu that are from an unique bloodline. (For example Hyuuga). Also, there are certain techniques attached to this doujutsu. (Which I will place under this template).

Information Clan Jutsu:
After achieving another Tomoe (Another Sharingan Stage) the Uchiha will directly learn a new technique attached to that stage. It doesn't need an other Uchiha to teach him that.

Sharingan Stages:
The Sharingan has three normal stages, one stage above those three, and then again one stage above those four. It will be explained here.

Normal Sharingan: This Sharingan has three stages. Each stage will give the user one more 'Tomoe' (comma's) into his eyes, also improving his movement/speed reading and copying of skills.

Mangekyou Sharingan: This Sharingan is to be unlocked with special ways. One Mangekyou is said to be unlocked due to killing a best friend, the other ways are currently unknown. Overusing this Mangekyou will lead to blindness. Also this Mangekyou has jutsu's attached to it.

Eternal Mangekyou Sharingan: This Sharingan is the Eternal version of the Mangekyou Sharingan. You have to steal another Uchiha's eyes and fuse them together with yours (with the help of a medical Ninja), to make the Eternal version. It doesn't matter how much you use this version, it'll never make you blind. Also it is said to be stronger than the Mangekyou Sharingan.
-----------------------
Sharingan Stages requirements:
-----------------------
Sharingan Tomoe 1: 200 posts, Genin rank and a near-death state.
Sharingan Tomoe 2: 450 posts, Genin rank and win against a Chuunin rank opponent.

-----------------------
Advantages: It can read the movements of others, each stage will increase the user's sight. Can copy techniques (also read above).
Disadvantages [AKA Weaknesses]: It is said that as long the opponent's of the Uchiha don't look into his eyes, they are safe. The very final stage, the Mangekyou, will lead to blindness if overused.

Mangekyou techniques:

Jutsu: Tsukuyomi - God of the Moon
Jutsu Type: Genjutsu
Rank: Chunin
Range: (As long as the user looks into the opponent's eyes.)
Description: Tsukuyomi, named for the God of the Moon, is a Genjutsu technique which uses the Mangekyou form of the Sharingan eye to generate a powerful illusion. This jutsu is generated by the left Mangekyou eye. This highly advanced technique can not be used extensively because of the toll it places on the user. To utilize the illusion, the clan member will look into the eyes of his opponent and cast a Genjutsu spell on them. The illusion takes place in the mind of the one affected, while under the jutsu the victim is at the total mercy of the user. The user has full control over space and time in the jutsu and can place the one affected through any hell they desire for any length desired. The technique itself only lasts for but a second in reality, but the one affected could have lasted through several days of torture.

It is said only a natural born member of the Uchiha Clan can overcome the illusion. To counter the technique, however, Mangekyou is not required. A highly trained normal Sharingan user can break the illusion, causing the Mangekyou user to experience additional weakness from using it.
[ The illusion will only last for one post and can be used once in a battle ]
Advantages: Works on any opponent, except for Uchiha's as they can overcome some of the Tsukuyomi. (As explained in the description.)
Disadvantages: An Uchiha can overcome the Tsukuyomi, opponent is completely. safe as long as he doesn't look into the user's eyes.

Jutsu: Amaterasu - Goddess of the Sun
Jutsu Type: Ninjutsu
Rank: Jonin
Range: Long
Description: Amaterasu, named for the Goddess of the Sun, is a Ninjutsu technique which uses the Mangekyou form of the Sharingan eye to create a powerful black fire. This jutsu is generated by the right Mangekyou eye. It has been said that anything within the Mangekyou's vision will burn to ash if consumed by the fire. The fire itself is said to burn for 7 days and 7 nights. Because of the amount of chakra needed to use the technique, it can only be used on a very limited basis daily. Though it is regarded as the strongest of Mangekyou's physical attacks, usage of the ability will degrade the eye further and lead the user to blindness.
Advantages: Completely burns the opponent away.
Disadvantages: User's eyes will bleed from it and hurt a lot, Amaterasu can be stopped: It is a one-hit technique, as soon as it starts to burn an object, it stays there. Though, the opponent must be fast for it.

Jutsu: Susanoo - God of the Sea and Storms
Jutsu Type: Genjutsu
Rank: Jonin
Range: Mid (User can walk when activated)
Description: [ This technique is performed by both Mangekyou eyes ] Susanoo, named for the God of the Sea and Storms, is a technique which uses the Mangekyou form of the Sharingan eye to create a sword wielding spectral form which will surround the user. This jutsu is generated by both Mangekyou eyes. Susanoo will first form around the user as a skeleton. This skeletal form will then generate muscle and armor for battle and wield both a sword and shield.

The sword is formed out of the sake in the gourd it holds, meaning the sword has no true physical form. This legendary weapon, known as Totsuka's Sword and the Sakegari Long Sword, utilizes the main ability of the jutsu. Anyone or anything cut by the blade will be sealed away into a Genjutsu of blissful oblivion until the end of time. It is said the sword is thus the ultimate counter to Orochimaru's Kusanagi Sword. The shield is known as Yata's Mirror. It is said this shield can defend against any attack. Together the sword and shield will make the Susanoo user nearly invincible. Like other Mangekyou techniques, usage of Susanoo will damages the eyes and health of the user. [ Once per battle and Susanoo stays activated for five posts
Advantages: Opponent will be put into an eternal Genjutsu.
Disadvantages: Only once per battle, user's eyes and health will be damaged.
