The REAL list of top 10 most underrated
10- Zetsu. He has mokuton style and can make a lot of clones, he is NOT the weakest akatsuki, zetsu>hidan IMO. Besides black zetsu is badass.
9- Zabuza. Silent killing + Mist jutsu is a very strong atack, your oponent can't see you or hear you. The sword is just a power up. Kakashi is just a bad match-up.... AGAIN, zabuza > hidan IMO.
8- Kakuzu. He es easely top 25 character, i've seen him in 37/40 spot, i mean, it took 3tomoe kakashi, naruto, shikamaru, choji, yamato, and ino to beat him HIGH diff.
7- Sakura. She's pretty underrated, i'm sure because she sucks (she's a ******), but she is strong and haters wont deal with it.
6- Kiba. We have seen him fight seriously just 1 time and he showed the most amazing jutsu, Jinjū Konbi Henge: Sōtōrō , this jutsu cutted in half sakon and ukon, who were Juugo level, so with this jutsu kiba can defeat a lot of strong oponents.
5- Sasori. He was really strong, he had a lot of strong atacks, with his 3rd kazekage puppet he has a chance against a lot of strong opponents, he's just underrated because he lost to chiyo (on porpouse)
4- Tsunade. She can break susanoo's defence with just one punch, she has regeneration and a healer summon, SHE IS NOT low kage level, she's mid kage. I'm not saying tsunade > kakashi wich is a big NO.
3- Orochimaru. He couldn't use his hands, we haven't seen his full potential, just wait, he would be top 10 for sure (actually he's top 13 in my list)
2- The rest of k11, we think they're fodders just because we haven't seen them in a while, they're strong, otherwise they wouldn' be important characters.
1- Killer B (no bijuu mode), owned taka, he went toe to toe with kisame and he beat his brother in a lariat fight, some of you say that he's nothing without Bijuu mode, but yes he is, he is really strong without it, top 25 material (with B. mode top 11)
