1)Nagato=This guy is seriously overrated.Nagato is really strong but to say he can solo Hashirama or Madara even at once is just stupid,crazy and IMPOSSIBLE.Hes not in the top 5 strongest.
2)Muu=Fanboys seriously overestimate him. Fanboys claim that since he can fly and shoot dust and has no presence he cant be stoped. With that logic, that menas onoki is that strong since he can fly faster. You all forget,Muu would have lost to onoki if he wasnt an EDO. Hes definitely not top 10 material.
3)Second Mizukage=This guy is really overrated because of the fact he killed muu. Thats impressive but also the reason why hes not top 10 material just like muu. If hes that strong then Gaara is in the top 10 as well since he knows all of the second's weaknesses and its a bad match up for the this badass water guy. Fanboys assume he can turn into a huge mass of water just like Suigetsu but not of us has seen him do it. His specialty is oil which is a really bad match up against uchihas.
4)Hiruzen Sarutobi=Fanboys just cant face the facts. Hiruzen in his prime just cant beat Hashirama or Madara. That is all.
5)Kakashi=Kakashi is really overrated because of Kamui. Kamui is a deadly technigue but its not an insta-kill. Deidara was too fast for Kakashi to get a good shot so I dont know he can get anyfaster than Deidara such as A,Minato,Itachi etc..
Honorable Mentions=Itachi-Minato-Kabuto-Third Raikage-Hanzo
Sauke=Sasuke is the most underrated characer in the naruto series. Sasuke is underrated all because of the haters. If Sauke is weak then Itachi is weak. If no fanboy of Sasuke but he is actually stronger than Itachi. Have some REAL logic haters.
Honorable mentions=Jiraiya-Tobirama-Danzo-Mei Terumi-Tsunase-A-Mifune
