Intro: Most of the Jutsu that is performed in the show, is performed only once or is done only by a single person. However, some types of Jutsu are performed often by more then one person. Some of them are Kekkei Genkai, which are ninja techniques that can only be obtained genetically in some clans. Some Kekkei Genkai are eye techniques, while others like ice style jutsu and wood style jutsu are mixtures of two elements of jutsu.
Sharingan: The sharingan is and eye technique that appears in a few members of the Uchiha clan. Unlike many other Kekkei Genkai, the sharingan does not appear at birth, instead it only appears when a potential user is in a life-threatening situation. Sharingan is an eye technique that allows the user to mimic any jutsu the opponent uses as long as the user has the physical ability to perform the jutsu. The sharingan is also capable of allowing a user to track incredibly fast moving objects easily, sometimes allowing the user to predict the movements of the object. The final power of the sharingan is the power of unique kinds of hypnosis, like putting the enemy to sleep, or creating many different illusions. It is possible for a sharingan eye to be transplanted into a non-Uchiha. For example, Kakashi's sharingan eye was transplanted into him by a deceased teammate. A heightened form of sharingan, called the Mangekyo Sharingan, allows the user different more powerful and unique ablilities. However, users of the Mangekyo Sharingan suffer sight loss the more often they use the technique, and usually end up blind unless they kill someone they share a close bond with.
Shadow Clone Jutsu: This jutsu is unlike the other forms of clone jutsu, because it splits the user's chakra among the clones, making each clone a complete copy of the user with a fraction of the user's power. However, this is also a very dangerous type of jutsu, because it drains a person's chakra very quickly. The more dangerous type of this jutsu is the forbidden form, Multi Shadow Clone Jutsu, which allows the user to create any number of clones, as long as they have enough chakra. Naruto is very skilled in this technique, and due to his enormous amount of chakra, he can create thousands of clones at a time.
Rasengan: Rasengan is a techique that relies only on the user's chakra control. It is a very difficult jutsu to learn, and perform so teaching it is divided into three steps where the student learns how to mold there chakra into the shape of a perfect sphere. The creator of the rasengan originally intended to combine rasengan with an elemental chakra, but failed. However, Naruto is successful in combining rasengan with his own wind natured chakra.
Chidori: Chidori is a lighning element based jutsu. It involves the user focusing their chakra into their hand and changing it into lightning. Kakashi's Chidori is sometimes known as Raikiri (lightning blade) because he once cut a lightning bolt in half with it. Kakashi also happens to be the creator of Chidori. Chidori is a very powerful technique, but the enormous amount of chakra it takes to activate limits it's usage to a few each day.
Byakugan: The Byakugan is a Kekkei Genkai that appears naturally in members of the Hyuuga clan. Users of the Byakugan have eyes with no pupils, however when the Byakugan is activated pupils appear and the veins near the eye bulge. The Byakugan allows the user to see for long distances in a near 360 degree radius with a small blindspot at the back of the neck. Users of the Byakugan usually use the Gentle Fist style of fighting with involves attacking an opponent's chakra system stopping the flow of chakra which can kill easily. Byakugan users are capable of using the Gentle Fist style, because they are able to detect an opponent's chakra system, which is invisible to the normal eye.
