He was hyped up early by wanting revenge on sasuke and oro, but he got drilled by gaara. I feel that if he would've gotten to grow he would've been strong.
It can easily suck in most attacks coming at him, but on offense it becomes difficult to use because it is hard for him to target somebody moving fast. If he can them in one strike that is great, but if he misses he is wide open for retaliation
