It would most likely have to be Shikamaru. You may not have noticed, but he was the only one that actually graduated to Chunin Rank, even though everyone else does exceed Genin Rank, Shikamaru was the only beneficial Leaf Shinobi that ever did graduate due to the Exams.
Yes they do, during the Chuunin Exams. incorrect officiall they don't fight in chuunin exams they fight after operation destroy the leaf comes into effect.
i think its every 4 years but I'm not sure
At first he doesnt cause neji'stalkin crap about destiny. but then after he beats him in the chuunin exams. He starts to understand naruto.
He failed the chuunin exams the first time and afterwards he didn't because he was traveling with ero-sensei for 2 1/2 years when everyone else became a chuunin.
Hinata has a younger sister named Hanabi in naruto. This is revealed in the finals of the chuunin exams when Hinata's father is talking with her while Naruto and Neji are fighting.
Yes he does, he had emotions about destiny and reacted with tears about what Naruto had said during their battle in the Chuunin Exams.
At first he did, but during the Chuunin exams he started to respect and like her for her determination when fighting Neji.
He hasn't become a Chuunin yet; he is still a genin, though his abilities prove otherwise. This is due to the fact that while training with Jiraiya during the timeskip, he missed the Chuunin exams. Also, he failed to become a Chuunin during the pre-Shippuden anime series.
In Naruto Shippuden he is a chuunin, but before he's a genin.
no his going to be a jounin
In the Shippuden yes.
So far, no
