Bloodline: Sharingan, Mangekyo Sharingan
Bloodline Ability: The first of the Sharingan's powers is being able to see the flow of chakra. The Sharingan can tell if a person is under a genjutsu because the person's chakra flow would be irregular.
The Sharingan's second-most prominent ability grants the user an incredible clarity of perception, allowing them to easily recognize genjutsu and different forms of chakra, though not to the same extent as the Byakugan. This also allows the user to pick up on subtle details, enabling them to read lip movements or mimic something like pencil movements. As the Sharingan evolves, gaining more tomoe seals, this ability extends to being able to track fast-moving objects before finally giving some amount of predictive capabilities to the user. However, even though the user may be able to see an attack or know it is coming, their body may not have time to react.
The Sharingan's third and most well-known ability is that it grants the user the ability to memorize any technique that he or she witnesses, apart from other kekkei genkai techniques. The user can memorize ninjutsu, genjutsu, and taijutsu with near perfect accuracy, allowing the user to use the techniques as their own, or even modify them to create their own new techniques. In order to reproduce a copied jutsu, however, one must have the necessary skill or ability to perform them. In addition to physical skill and kekkei genkai techniques, the Sharingan cannot reproduce jutsu dependent on other factors, such as summons that the user has not signed a contract with. (Jutsu is only able to be copied by Ninja in the Copy Wheel Path, but basic fighting movements using fists, feet, swords, etc as well as behavioral movements can be copied by every Uchiha)
The Sharingan's final commonly-used ability is capable of inducing a unique brand of hypnosis that involves suggesting actions and thoughts to the opponent through genjutsu cast by simple eye contact. More advanced Sharingan users can take the hypnosis ability even further to the point where a powerful summons or even Bijuu’s may be controlled. When this was used against summons and the Bijuu’s their eyes took on the tomoe pattern of the users' Sharingan while under hypnotic influence.
The hypnotic ability coupled with the other aspects of the Sharingan, can make the user appear as if they can "see the future". First, the user must perfectly mimic every move their opponent makes and possibly their thoughts and words through careful observation. Then, they suggest an action to the opponent such as hand seals for a jutsu that the opponent and Sharingan user already know and copy that. With these things done, the user can complete the action even before the opponent does, possibly using the Sharingan's genjutsu to confuse or delay them. As with other genjutsu, genjutsu cast by the Sharingan are capable of putting an opponent to sleep, inducing paralysis, replaying memories to someone else, or creating various illusions to deceive someone. The potency of the Sharingan's illusion is dependent on the user's knowledge and skill with implementing genjutsu.
Although the Sharingan consumes the user's chakra while active, the chakra levels that the user must exert is so insignificant that they can keep it active constantly. However, when a Sharingan is transplanted to a non-Uchiha, the chakra drain is significant, leading them to cover it up when not in use, to stop the drain.
The Mangekyō Sharingan gives the user access to several powerful techniques, including the powerful fire jutsu Amaterasu and the almost unbreakable genjutsu Tsukuyomi. The Mangekyō Sharingan erodes the eyesight of its users, eventually causing blindness, which can be prevented by obtaining another pair of Mangekyō Sharingan from a sibling. The new Sharingan is dubbed the Eternal Mangekyō Sharingan
Kamui Path: A balanced combination of both trickery and destruction.
Name: Magen: Mirror Heaven and Earth Change
Canon/Custom: Canon
Type: Genjutsu (E-S rank.)
Element: N/A
Distance: Any
Description: The user decrypts a genjutsu that has been applied onto them and casts back a technique with identical effects onto the opponent. It's a form of illusion reversal, but in order to instantly read through a technique and cast it in return, the Sharingan's power is necessary. As genjutsu is initially used to confuse the enemy, this technique, which sends it right back to its caster, deals a high amount of mental damage, more than anything else. Does not require handseals, but does require third-tomoe Sharingan. The post length of the genjutsu and methods of escape for the genjutsu are the same.
Name: Katon: Great Fireball Technique
Canon/Custom: Canon
Type: Ninjutsu (C Rank)
Element: Katon
Distance: 50 Feet
Description: A technique where chakra kneaded inside the body is converted into fire, and expelled from the mouth in a massive orb of roaring flame. The scope of the attack is altered by controlling the volume of chakra that is mustered. The released flames will engulf their target, and leave a crater on the ground's surface. At its largest, Goukyaku no Jutsu is 10 feet in diameter, and can travel at 40 mph. Requires hand seals. This technique can leave severe third degree burns at its center (a five foot radius from the exact center) while the rest of the fireball gives off second degree burns. 6 post cool down.
Name: Manipulated Shuriken
Canon/Custom: Canon
Type: Ninjutsu (B Rank, 2 Post cool down.)
Element: N/A
Distance: Any where within reach of wire
Description: With this technique a translucent string, both elastic and highly durable, is attached to a shuriken, making it possible to alter its path after having thrown it. An expert will have the ability to freely glide the shuriken in any direction with just a single movement of their fingertip. The first attack, challenging the enemy, is avoided and after a timelag of one post, it will come from behind. Depending on the performance, the possible tactics can be infinite. Can only be done to ten small shuriken at one time. Following the means of this states that the damage control is 2 inches maximum. Due to the speed and projectile itself it can penetrate up to two inches into the body of a target with the bruising of an area or other damages to muscle being a one inch radius if punctured or a half inch radius if only cut. (55 mph)
Name: Copy Wheel Eye
Canon/Custom: Canon
Type: Skill (Passive)
Element: N/A
Distance: Within eyesight
Description: The Copy Wheel Eye allows the Uchiha ninja to memorize and possibly learn any jutsu they see when the Sharingan is active. The jutsu, once seen, can be memorized for the course of the user's life. To be able to use any jutsu seen, it must either be non-elemental, or be one of the clansman's elemental affinities. The clan member may not learn any jutsu outside one of their specialties (if the clan member is Ninjutsu, Genjutsu, and Kenjutsu, they may not use fuuinjutsu or Ijutsu technqiues they've seen). If the Uchiha is D-rank, they may not use any S-rank jutsu they see. Also, any jutsu used must be paid for in the Technique Shop. If an Uchiha wishes to be able to use this skill, they will NOT be able to use either Tsukuyomi or Amaterasu. Special cases cannot be copied. Copied jutsu are free to be used in the battle that they are originally copied without charge, but if the user wishes to keep the jutsu permanently, they must pay after the battle for it. This skill does not cause blindness. This skill also negates all stat boosts regarding reaction timing in the user, because the user's reaction time is naturally completely flawless as long as the Sharingan is active.
Name: Kamui
Canon/Custom: Canon
Type: Space-Time Ninjutsu
Element: N/A
Distance: Within eyesight
Description: The Kamui allows the user to transport virtually anything to another dimension. When this is activated, it appears as though space itself begins twisting, and then eventually disappears. In this alternate dimension, time does not exist, meaning that if the Kamui is activated on oneself, the user can use it to virtually teleport to any none location. The Kamui's main function is intangibility.
There are two options for the Kamui. The first, is only transporting certain parts of your body to make it appear that intruding weapons (like fists or weapons) slide right through the user, leaving them undamaged. The second is using the Kamui to transport oneself to the other dimension, traveling through that dimension, and coming out somewhere in the real dimension, appearing to teleport. In battle, travel through the other dimension doesn't need to be detailed, just state that you teleported using the Kamui and it will be understood. The user can also teleport anything or everything making physical contact with their own body (like other people or weapons). Both versions count as a use.
Stipulations
Using the Mangekyou Sharingan, the Kamui can be used thrice in one battle. After trying to use it a fourth time after having already used it thrice, the bad effects take place. Unlike the Amaterasu or Tsukuyomi, the Kamui does not cause blindness, but instead causes extreme wear and fatigue on the user for having to concentrate accurately trans-dimensionally. After trying to use it once past the limit, the user enters a comatose state for three days, and then for four days after that the user cannot exert any more energy than walking, or they risk slipping back into a coma and starting the process over. Using it a fourth time succeeds, but as soon as the user is finished casting it, they black out. It may be used to escape a battle topic once a week, and it can be used endlessly in casual topics. No cooldown or charge.
Using the Eternal Mangekyou Sharingan, the user can use the Kamui 5 times, and then they simply cannot do it anymore. No bad effects.
