akljaslk why is this so difficult. I think it's hard to pick my least favourite characters because most of them are not "I dislike this character" but "I dislike how this character's written". Oh, Kishimoto, I hate and love you at the same time. So here are the character I dislike mainly for messing up the plot and/or other characters that I do like.

1. Gaara's dad.
2. Orochimaru.
3. Sasuke's parents.
4. Gaara's "uncle".
5. The Akatsuki--with the exception of Itachi.
