he gets free power-ups like its no big deal.
-all of itachis techniques, all of oros moves (curse mark), he just gets moves given to him.
-he thinks he can take on anyone and everyone and has to get bailed out every time. (against onoki, against kakashi/naruto/sakura/naruto, against itachi, against yammato/sai.saukra/naruto, kabuto, etc.)
-he is going against his brothers dream because he loves him? i thought his brother died for the leaf and since he loves itachi so much, he is gonna destroy it.... wait what??
- his attitude. he thinks he is the shit and can take on the world. he thinks is too cool for everybody.
-he is a guinny pig for everyone. (for oro,(the vessil) itachi,(to "hate"him to kill itachi) and for tobi.) (tobi when he was in the akatsuki and when he was in taka)
thanks all i can think of right now
