The upgrade speed of Kakashi is surprising, just the aspect could prove he is a genius. He has too may mysterious, such as his real appearance under the mask, why he always late for several hours, and the story about his left eye…… in short, Kakashi usually use his unmeaning attitude to conceal his hard history. He bear so many things, as the first technician of Konohagakure, he is deserved.
Shikamaru Nara deserved to be a genius as his IQ is 200. In my thoughts, Shilamaru is a man who understands life and enjoys life. There are so many people who fall into the desire and till drowned, someone say the tidemark of life is Lhitachi, Shikamaru is the best one who do this. Shikamaru want to live a ordinary life, but Athena give him a superior IQ, so he have no other way. He said he envy cloud, actually Shikamaru like a cloud which could not control himself, and as a Ninja, his philosophy of life seems incompatible to others.
Set Naruto as genius, maybe there have some people did not think so, Naruto always the last of his class. However, I think be last not mean anything, there have so many great men are not good at their study. Why Naruto is the genius, mostly is for his powerful explosive force in a time of emergency. When Naruto enter into fighting, he become a founder of miracle.
All his clansman of Sasuke have been killed by his brother, bear such a deep hatred, he arouse himself to become stronger. Maybe to Sasuke, to be a genius is logical, as a avenger, he need to be hematocryal. In this anime, when we saw Sasuke become lonelier and lonelier, we always fell sorry and heart break for him. Compare with revenge, there have many other things could do, we really hope Sasuke could come back.
Hyuga family is the famous house of Konohagakure, who is luck to be born in this family. Hyuga Neji inherit the best Kekkei genkai, but he was born in branch of family, and the Hinata is an unlikely figure, we could not help plaint, it is fate.
The feeling Yakushi Kabuto gives us is he is a genius, I don’t know how to describe him, he is good at every aspect. His lot is more mysterious than Kakashi, I have thought they are brothers, and till know I hope so. However, he follows Orochimaru, he should be the elite Ninja of Konohagakure.
As the biggest villain of Naruto, Orochimaru is no doubt a genius. He is a ambitious man and usually someone who is ambitious are always also powerful. He never make light of others and could not ignore others. His strength is his ambitious, we do not know what should he benefit if he destroys Konohagakure, but just in his strength, he is very powerful.
