Yay!! Okay, I know that are Barraki likes and dislikes are over, but I still must say my favorite Barraki would be Pridak. I've always liked white Bionicles (with the exception of the white Visorak), so that explains a bit of it. Also, Pridak's waist articulation is awe-some, and so are his blades!
My least favorite Barraki would have to be Carapar. There is something about him I just don't like (I think it's his arms being longer than his legs)!
