Sharingan is a dojutsu Kekkei Genkai passed through the Uchiha clan. It posses multiple abilities & has three different stages, ranging from a single tomoe to three individual tomoes. The overall abilities of the sharingan include, being able to see chakra & recognize different chakra from each person. Being able to perceive an opponent's movements due to the ability of focusing solely on their muscle tension, & having the ability to focus on faster movements (making it seem as if in slow motion), which in turn allows the user to follow a string of handseals made by the opponent & mimic them with almost exact timing. The user being able to see chakra allows them to notice the flow of one's chakra, noticing any differences in their chakra(such as foreign chakra). These abilities can heighten during each stage of the Sharingan, such as..
One Tomoe - To awaken one's sharingan they have had to of gone through an emotional tragedy. One tomoe allows the opponent to perceive motions at a speed that only a higher level rank could follow. It is also able to follow commonly used Taijutsu techniques even if improved with a slight gain of speed. Visual Genjutsu of D Rank or below can be noticed with the use of Sharingan
Two Tomoe - The second stage of Sharingan has heightened abilities of the first. Also allowing to copy movements of the opponent if they are physically possible. They can perceive faster movements than the first tomoe giving them a better chance to react to the offensive & copy a Ninjutsu technique used by the opponent by mimicking the handseals performed. The second stage allows the user to recognize Genjutsu of C Rank & below.
Three Tomoe - The final stage of the basic sharingan. This allows the user to perceive motions at a faster pace, to a certain extent predict basic movements & even copy such movements if it is physically allowed. The sharingan can tracks exceptionally high speeds & copy Taijutsu to the letter. A newly acquired power to the sharingan which allows the user to create illusions which effect not only the targets mind but also there senses, most techniques such as these would require direct eye contact to achieve. The user is able to notice B Rank & below genjutsu.
I look toward my sensei & slowly close my eyes. In a dramatic Uchiha fashion I suddenly open both eyelids, widening as much as possible, my eyes bulge out with my iris covered over in a crimson red. Three tomoe are revealed around each pupil.
Chakra: 30 (-10 per turn to keep active)
One of the Three Great Dōjutsu (San Daidōjutsu), the Sharingan is the kekkei genkai of the Uchiha clan. Unlike the other Dōjutsu, not all members of the Uchiha Clan possess the Sharingan. This great Dōjutsu seems to awaken only on exceptional Uchiha members and only in times of great stress. Once awaken, the pupil turns red and a single tomoe (巴) seal appears around the center pupil. As the user masters and evolves their eyes, the tomoe (巴) seals increase, topping 3 per eye. The main ability of the Sharingan, like any other Dōjutsu, is to enable the user to see the flow of chakra. This ability is further improved as the Sharingan gives color to chakra, enabling the user to differentiate chakras from different people or from different sources. Although the user can see chakra through matter, he cannot see beyond dense matter or in long distances. Coupled with the ability to see chakra, Sharingan users gain acess to an incredible clarity of perception that enables them to read insanely fast movements or minor details, enabling them the ability to foresee in an easier way, traps, incoming attacks, etc. This clarity of perception is so great that a Sharingan user can sometimes start performing a counter to an attack that is still being performed, enabling the counter to be launched only a split a second after the attack. This clarity of perception leaves Sharingan users able to track high speed movement easily as well as to read through handseals. This last ability enables them to learn techniques much faster and sometimes copy them directly from the enemy, as long as the user has the necessary chakra affinities and requirements to perform it. Finally, the Sharingan is often linked to Genjutsu and mind-manipulating illusions, mostly because the user can, mostly through Eye Contact, directly and precisely use his chakra to manipulate the enemy's chakra flow. In return, the users clarity of perception gives him the ability to more easily decipher visual illusions cast upon him and see past them. The Sharingan has a great cost to the user though. The chakra consumption disables its use for long periods of time and, even when the user grows stronger, it's still hard to keep it active for long periods of time.
Note: The user, if he hasn't gained full mastery over his Sharingan, will need to spend a move to activate it, although as long as he has chakra and enough stamina he'll be able to keep it active until the end of the match. If the user is Sannin Rank or above and has gained his 3 Tomoe Sharingan and held it for one month, he becomes able to passively activate it, meaning he'll no longer spend a move of his 3 per turn.
Note: To avoid direct Eye Contact and be able to focus only on the body movement below the chin, the opponent needs to have mastered Taijutsu to possess the necessary skill.
Note: Predicting the nature of a technique or what it exactly is requires the user to either know the technique or that its a cannon technique.
Note: Danzo and Kakashi bios activate the Sharingan by removing the covers in their respective eyes and suffer a +10 chakra consumption per turn penalty
Note: The user is bound by the abilities and limits of the stage of sharingan he possesses, stated in the rules of the KG.
Because I was bored with 2 tomoe .
I have had my Sasuke bio for a long time now (longer than you traitor) & really want him with a full arsenal. I try my best to RP as Sasuke along with the limiting my elements to lightning & fire & I could do so much better with an extra tomoe. Uchiha are one of my favorite clans. #SasukeonehitMinato
