Naruto has 4 main
techniques which are Kage Bunshin No Jutsu, Tajuu Kage Bunshin No Jutsu,
Kuchiyose No Jutsu and Rasengan.
Tajuu Kage Bunshin No Jutsu is also a shadow replication technique but it is actually mass shadow replication technique which means Naruto can make more than a hundred other Narutos!
Kuchiyose No Jutsu is a summoning technique which Naruto uses to summon Gamabunta which is the king of all frogs. Gamabunta is a giant frog and is very powerful. Naruto learnt to summon Gamabunta from Jiraiya-sama.
Rasengan is also one of Naruto's new technique and is also taught by Jiraiya-sama. Rasengan is a wind element jutsu and uses chakra to perform. If someone is hit by Rasengan, they would fly off spinning and far away. This technique was created by Yondaime and it took him 3 years to master and Jiraiya-sama also needs a lot of time to master this technique but Naruto only takes 3 weeks to master the technique! That's incredible! That is exactly waht you will get if you are hardworking...
Sasuke has 3 main techniques which are Sharingan, Chidori and Katon Ryuuka No Jutsu and Katon Goukakyuu No Jutsu.
Katon Goukakyuu No Jutsu and Katon Ryuuka No Jutsu are basically the same and is the basic to each of the Uchiha Clan. So Sasuke needs to learn this technique if he wants to wear the Uchiha shirt.
Chidori is limited to someone who has Sharingan only. Chidori isa Ninjutsu technique where the ninja using it grabs their wrist, and then collects enough chakra into their hand that it becomes visible to mere human eyes. With enough chakra collected into one focal point, that point becomes powerful enough to destroy an entire cliff side.
Sharingan is an advanced bloodline technique belonging to Konoha's Uchiha Clan. The Sharingan grants its bearer utter immunity to most Genjutsu, and the ability to copy Ninjutsu, and follow Taijutsu. It is said that the Sharingan can find its roots in the Byakugan.
