First I want to apologize for bringing up this thread again, but I read it just now.(I'm new)
I also want to apologize for writing so much but I had so much in mind and I wanne share it with u guys.
OMG I can't understand u guys at all. All of u suggested that itachi is the strongest (except one) and all of u treated kisame as a weakling. Thats why I had to sign in here and write my opnion. I do not agree with u guys at all.
I truly believe that Oro is the strongest. (first I give u my list then I'll explain)

1. Orochimaru
2. Jiraya
3. Itachi
4. Tsunade
5. Kisame
6. Kakashi/Gai/Kabuto

Well there's a simple explation why I ranked them the way I did. Itachi (as someone I think already said) is just 17.
damn guys just fucking 17. its nothing he's just a boy and with all the honor (and I have one for him he's still ranked so high for his age) he can't be compared in fighting lvl to Oro/Jir. U guys underestimate Oro too much. I know backthere Oro said something of him being less stronger than Itachi but I believe he meant itachi would be stronger than him when he'll get to his age, and not now when he's just 17 and Oro is an exprieneced crazy dude.

Now to explain why Kisame is treated to be so strong. Ok guys read this and think about it, Kisame is inside the terrifying clan "Aktsuki"(Red Moon), if u ranked him below kakashi that's means kabuto is stronger than him and kabuto could be in the Aktsuki, which makes no sense. I believe kishimoto is yet to relieve the true power of Kisame. Also do not forget how aktsuki members mantioned Kisame's chakra to be so high.(and I know it was said after u guys wrote it but still) That must means he has some crazy ass abilities.

As for kakashi I never thought of him as an Hokage type or an Hokage lvl type. He's just too weak for it by now, but as I said he's just 27 and could get much stronger in the future do not forget.

I also want to flatter to the guy who devided the "who's the strongest" list to the younges and over 16 aged. I think it was very smart and right doing so. Naruto's and Sasuke's power cannot be lvled or compared to those of the old guys. it's just no fair, the reason is the fact they will get much stronger in future, and this is my list:

1. Garra - which I believed (before aktsuki took his demon) will get to be the strongest char in the future.
2. Naruto
3. Neji
4. Sasuke (can't really tell cause hadn't heard of him for almost 3 years)
5. Lee (yes I treat him weaker than Neji, although he's an extremly dangoures taijutsu type, ninjutsu/genjutsu is what counts)

amm I remembred someone asked for kimi's clan. Well it's called the "kaguya" clan.
