significance to the story: teammate of the main character
age: uhh...i guess around the same age as naruto, so 12
likes: not much (he seems to like fighting)
dislikes: a lot (i'd say he dislikes the guy he wants to kill)
strength: speed and not freaking out
weakness/faults: not many, the only one i can think of is the bruise he got while fighting the snake guy.
hobbies: i dunno what he does in his free time...training maybe.
goal in life: resurrect his clan and kill his brother
short bio: He is the #1 student in his class. He's always cool and very serious. He is on the same team as Naruto and Sakura with Kakashi as their jounin-sensei. Sasuke wants to be a ninja so that he can resurrect his clan. His other goal in life is to kill some guy (it's a secret!). He's very fast and doesn't freak out during a serious battle. He and Naruto both dislike each other, but they learn to tolerate each other as the story goes on. Sakura has a crush on him, but he just brushes her off (but she just keeps going after him anyway). Sakura is not the only one who has a crush on him. Every girl that shows up in the story seems to mention or think at least once or twice that he's cute. I think it's safe to say that he's pretty much an introvert and keeps his thoughts to himself, unless he's insulting Naruto or rejecting Sakura. And the likes and dislikes are from when Naruto, Sasuke, and Sakura were telling Kakashi about themselves.
*spoilers*
i think sasuke is pretty cool, but if he were a real live person, i probably wouldn't like him. the person he wants to kill is his brother. i don't know what the history is, but his brother told sasuke that he should cling to life and run away in the face of danger if he ever wanted to beat him, which is why he was such a chicken in the forest of death. during the battle with haku, sasuke learned how to use the sharingan in both of his eyes and he is able to turn it off and on at will. the sharingan is a physical characteristic on certain members of his clan. it enables you to see through attacks of any form and to copy and opponents technique after you see it once. sasuke does a lot of taking care of naruto, so i don't think that he hates naruto entirely. sasuke offered naruto food near the beginning of the manga when naruto tried to cheat and wasn't allowed to eat as a penalty. he also protected him while fighting with haku and died (at least, he was dead for the rest of the battle and missed out on naruto's transformation) in the process. he also saved naruto when they got attacked in the woods by the mist ninja's. more evidence is that in the beginning of the story, sakura says that naruto is lucky not to have parents and she complains about hers. then sasuke calls sakura annoying after telling her that naruto's life ain't all peaches and cream (well, not in those words, but that was the gist (sp?) of it). the reason behind that is probably because he doesn't have any parents either and knows how naruto feels. when he was smaller, his parents and the rest of his clan was killed before his eyes and he wasn't able to do anything. that's prolly why he tries so hard to be strong. sakura has a huge crush on sasuke and will stop at nothing to get his attention, but he doesn't seem to care for those kinds of things and his main focus is becoming stronger. however, he does seem to care about sakura to some degree. when sakura was depressed about being weak and useless, he noticed and cheered her up by subtly complimenting her abilities to analyze genjutsu or something like that. during a flashback, they showed sasuke's past self. he dressed like a wimp...^^ orochimaru wants sasuke to become his heir or something because sasuke shows a lot of potential. then orochimaru bites sasuke on the neck, leaving some strange symbol where he was bitten and he (sasuke) promptly passes out and that leaves sakura alone (b/c naruto passed out too). sakura gets beat up on by these evil genins that were working on the orders of orochimaru to kill sasuke. when sasuke wakes up from his dreamstate, he has the symbol spreading from his neck and he's super fast and stronger and his chakra is 'different'. not to mention kinda bloodthirsty. this part shows that sasuke cares for sakura, because he started fighting because they beat up sakura. also, when sakura realizes he's not being himself, she stops him. see...only she could stop him!
