Obviously, the main character is Naruto Uzumaki. From what I've read, most of the other definitions are whining about how Naruto is crap because he wears a bright orange jumpsuit, and how ninjas are meant to wear black to represent stealth.
Naruto's personality is bold but foolish, and therefore he wears a boldly yet annoyingly orange jumpsuit to represent that. Duh.
The second main character is Sasuke Uchiha. His arrogance and "sexy moodiness" seems to be very attractive for his fangirls, but in actual reality he is a very annoying pool of piss that should be just booted off the anime altogether.
Third is Sakura (forgot her last name), she has no dreams whatsoever except to screw Sasuke, and she likes to beat up on Naruto. Oh and she hates Ino, this blonde girl with a high pitched voice who also dreams of screwing Sasuke someday.
Shikamaru's a pretty decent character, except in Naruto Shippuuden he gets overly attached to Asuma (his sensei). Chouji is a guy who does nothing but eat. Kiba is a funny dude who has a giant dog, Hinata is a girl who has a crush on Naruto (her voice...very uh, highpitched). Oh and there is Shino, I personally don't like him cuz he has bugs inside his clothes and I find that creepy.
Kakashi is Naruto's sensei and apparently his mask, which covers up 3/4 of his face, is sexy.
Don't get me wrong...I'm not a hater of Naruto, I quite like the anime, I'm just pointing out the flaws of the characters which makes the anime entertaining.
During lunch in school, Naruto walks up to Sakura and asks to have lunch with her. She insult him and asks Sasuke to have lunch with her. He proceeds to reject her and walk off.
