Leaf Clan Number

The Uchiha clan descended from the elder of the two sons entrusted by the Sage of the Six Paths with his power and will. When it came time for the Sage to chose a successor, he questioned the two on what course of action they would follow to bring order to the world. The elder believed that might was the way to bring peace, while the younger believed love was the way. The Sage favored the ideal of the younger brother, and therefore designated the younger as his successor, causing the elder to be filled with jealousy and hatefulness. From the younger boy descended the Senju clan who would be the eternal rivals of the Uchiha.

Before the founding of the ninja villages, the Uchiha were one of the many mercenary clans for hire. Because of their Sharingan, the Uchiha clan came to be known as one of the two strongest clans, the second being the Senju clan. Madara Uchiha was particularly powerful, and, upon attaining the Mangekyō Sharingan, he took control of the clan. Under his leadership the Uchiha grew stronger, conquering whatever clans they came upon, such that, whenever the Uchiha clan was hired for a job, the opposing side would hire the Senju.

he first of the Sharingan's powers is being able to see the chakra flow. 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[3] or mimic something like pencil movements.[4] 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 his own, or even modify them to create his own new techniques, much like Sasuke Uchiha's Lion Combo. In order to reproduce a copied jutsu, however, one must have the necessary skill or ability to perform them. A prime example is Rock Lee's brand of taijutsu. While Sasuke was able to copy some of Lee's moves, they put a much more significant strain on him since he hasn't trained nearly as much as Lee has. 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.

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 simple eye contact. When used against animals, the eyes of the target take on the pattern of the users Sharingan while under its influence. When used in conjunction with the other aspects of the Sharingan, this allows the user to perfectly mimic every move their opponents make even before they do, making it appear as if the user can "see the future". More advanced Sharingan users can take the hypnosis ability even further by tricking or even trapping their opponent within an illusion. It also allows for other forms of hypnotism, such as putting an opponent to sleep, replaying memories to someone else, or creating various illusions to fool an opponent. The potency of the Sharingan's illusion is dependent on the user's knowledge and skill with implementing genjutsu.

The Hyūga clan (日向一族, Hyūga Ichizoku; Literally meaning "Hyūga family") is one of the oldest and most powerful clans in Konohagakure. All members born into the family possess the Byakugan, a kekkei genkai that gives them extended fields of vision and the ability to see the chakra circulatory system.
Members of the Hyūga branch house

The clan is separated into two parts, the main house (宗家, Sōke) and the branch house (分家, Bunke), a system that protects the secrets of the Byakugan from outsiders. The main house runs the family while the branch house protects it. The members of the branch house are branded with a cursed seal upon the next heir/heiress of the main house's third birthday. This seal gives the main house members absolute control over the branch members, because they can destroy the branch members' minds with a simple hand gesture, or cause them great pain to punish them. This seal also makes sure the secret of the Hyūga's Byakugan is safe, because it seals the Byakugan after the wearer of the seal dies. Because they are essentially servants, simply because of their birth order or heritage, some branch house members are hostile to those of the main house.

Members of the clan are instructed in the use of the Gentle Fist style, which uses the Byakugan to view the opponent's Chakra Pathway System and deal precise blows to disable and impede the flow of chakra. Due to training in this style, Hyūga clan members tend to have excellent chakra control. This is emphasized in jutsu that utilize this chakra control, as well as the nuances of the Gentle Fist style. The clan's strongest techniques, like the Eight Trigrams Sixty-Four Palms, are only allowed to be taught to members of the main house.

The first ability of the Byakugan gives the user a near 360º field of vision, except for one blind spot at the back of the neck above the third thoracic vertebra.

The second ability is being able to see through solid objects, and can use a degree of telescopic sight. The distance and the degree of telescopic sight varies from person to person, and can be improved. In Part I, Neji Hyūga was able to see an area of 50 meters, but later he increases his visual range to at least 800 meters, while Hinata Hyūga's range in Part II stretches at least as far as 10 km. However, the Byakugan cannot see through certain barriers, such as the Four Black Fog Battle Formation used by the Sound Four.
Chakra Pathway System

The third and one of the greatest uses of the Byakugan is the ability to see chakra, as well as the chakra circulation system inside another's body. It is from this particular ability that they are able to employ their ultimate attack style: Gentle Fist. Unlike the Strong Fist, which is focused on external injuries, the Gentle Fist style focuses on internal injuries. Each strike, when placed correctly, strikes along the chakra pathway system, which is the network of vessels that carry chakra. This network is closely intertwined with the functioning of the body's organs, and so, when the keirakukei take damage, the organs suffer as well. There is no defense against the Gentle Fist, since one cannot train one's internal organs to become stronger. The only possible defense is to stop the Gentle Fist's hits from connecting.

Particularly skilled users of the Byakugan can take the Gentle Fist style one step further. Along the keirakurei are 361 pinprick-sized nodes called tenketsu, or chakra points. When struck, the Byakugan user can choose to either seal, or forcibly open these tenketsu, thus giving the user complete control over their opponent's chakra system. So, with precision, all those points along the victim's body can be sealed, stopping the chakra flow to those areas. Able to strike without force, and yet do more damage to a ninja than some of the most powerful ninjutsu, the Gentle Fist is the greatest taijutsu style known in all of Konohagakure.

he Aburame clan (油女一族, Aburame Ichizoku; Literally meaning "Aburame family") is a clan characterized by their use of insects as weapons. The insects live in symbiosis within the body of the shinobi. At birth, members of this clan are offered to a special breed of insects called destruction bugs as a nest, residing just under their host's skin. The insects can leave and enter through various pores, apparently by eating their way through the skin. They feed on chakra as a food source, making them quite deadly. The relationship between the shinobi and the insects is mutually beneficial. The host grants the bugs shelter and allows them to feed off their chakra, their body becoming a living hive of tens of thousands of these bugs, and in return the bugs do the user's bidding, allowing the shinobi to perform ninjutsu-like techniques without the use of hand seals or chakra conversion.

A female bug can be left on a target, which then can be tracked by smell by the male bug, or scout bugs can be sent out and return to tell the host information about the area. For this reason, Aburame clan members are experts in espionage; they can communicate with the bugs, and the bugs specialize in stealth because they make no noise or motion during combat. In addition to utilizing insects in battle, the Aburame clan also studies insects.

The kikaichū (寄壊蟲; English TV "Parasitic Insects"; Literally meaning "Parasitic Destruction Insects") are a species of small, beetle-like insects that are bred and utilized exclusively by the Aburame clan, forming the basis for all of their unique techniques. All members of the Aburame clan actually live in symbiosis with the kikaichū through the Destruction Bug Host Technique: The Aburame clan, shortly after birth, allows the kikaichū to nest and breed inside their bodies and feed off of their chakra, and in return, the host ninja receives the life-long ability to control and command the bugs, using them as their primary fighting technique.

The Senju clan was descended from the younger of the two sons of the Sage of the Six Paths. He was born with the "body" of the Sage, inheriting his father's strength of will and physical energy. The Sage's younger son believed that love was the key to bringing peace to the world. The Sage grew to favour the ideals of his younger son over those of his older son, who believed that power alone was the true key to finding peace. Therefore, on his deathbed it was the younger of the two brothers that the Sage chose to name as his successor. The elder brother, bitter and hateful at having being denied what he felt was rightfully his to inherit, attacked his younger sibling. The Uchiha clan would descend from the elder brother, resulting in the bitter centuries-long rivalry between the Senju and the Uchiha.

The Senju clan gained their fame in the era before the founding of the hidden villages. Where other clans focused on mastering one particular skill, the Senju were masters in all skills, from ninjutsu, to taijutsu, to genjutsu. Because of this, they were feared as "the clan with a thousand skills" (「千の手を持つ一族」, "sen no te o motsu ichizoku"), which gave them their name Senju (千手, "a thousand skills", "a thousand hands"). Wood Release is also available to senju shinobi.

Kekkei Genkai: The Yukina, or Ice Users, have the bloodline ability to combine the Wind and Water Elements to take control of the growth and formation of ice based structure. Their natural weakness is the Fire Element.
