Naruto and Kurama are bro's, he can go 4 tailed and keep all of his sanity ect ( much like Bee does ) and even have Kurama's help.
In any case, explain how all of those people beat someone who can't be touched and fires TBB's.
4 Tails Naruto is the one who faced Orochimaru at the start of Shippuden. If you refer to Naruto using a V4 Cloak, you should specify this in the title.
Regardless, I disagree. Honestly, most of Akatsuki can still defeat him. Don't forget that this is the same organization that caught ALL of the other tailed beasts (except I suppose the Hachibi). Meaning members of Akatsuki managed to take down the 5-7 Jinjuriki... and technically 8 if there wasn't an interruption. All of those Tailed Beasts are stronger than 4-tailed Naruto.
So no. I blatantly disagree.
Zetsu: Zetsu uses Mokuton which is noted to have counter Bijuu properties. Black Zetsu was capable of taking on the Mizukage, Minato's Bodyguards, a Mist Swordsmen, and even several other high class ninja. While playing defense he managed to even trip up KCM Naruto. Considering he can use Mayfly to escape any attack, and can use Bijuu Surpressing antics... he's almost an Anti-Bijuu Tank. Also, Zetsu has the greatest stealth in the series. Black Zetsu could hide under Obito and on the battlefield even while Naruto was in Chakra mode (AKA: Could sense people). He could sense the Hokage coming, but he couldn't sense Kuro Zetsu.
Hidan: If he's coated in his own blood.... that makes things easier for Hidan. The real question is can he draw his Jashin circle. If Naruto is conscious, the chances actually lean in his favor as a raging Kurama wouldn't afford that opportunity. I'd actually lean towards Kurama Naruto simply because of the fact that this mode could rip Orochimaru in half. The chances of Hidan drawing a circle are slim IMO.
Konan: I don't see any way 4 tail Naruto can win. Konan is paper intangible. You're also assuming he'd be able to hit her with the TBB. Orochimaru stood there and attempted a tank. We saw Konan can entirely disperse herself. So she simply dodges by moving around. Naruto is more likely to burn out his chakra before Konan burns out her own. I mean, the rate at which he spams is FAR greater than how conservative Konan is. While her paper weapons and bombs wouldn't cause fatal injuries... over time they are going to force him to exert more effort. Konan is also a far smarter opponent than Naruto. In the end.... I'd give it to Konan between her intellect and her paper morph.
Deidara: Naruto can't touch Deidara.... all the latter has to do is fly in the air. Nothing Naruto can even do. He'd just drop bombs on Naruto until Kurama's chakra is burned out.
Sasori: Might actually win with ease. You've noted Naruto basically coats himself with his blood: Guess who uses poison?! Sasori uses poison. Between his puppets' poison needles, poison gas, and the iron sand... Naruto would technically get poisoned. like Deidara, Sasori technically has pseudo flight... using the Iron sand as wings.
Kisame: Kisame solo'd the 8 tails... I'm sorry, but there is NO way 4 tails Naruto can defeat Kisame....... Kisame also solo'd the 5 Tails Jinjuriki who could use Lava (Which trumps suiton). Naruto's taijutsu is nowhere NEAR Gai's level.... that's an insult to Might Gai. 4 Tails NEVER even moved as fast as Lee using the Lotus to be honest. Regardless.... Kisame just has to use Samehade to defend, and he'd basically sap away the chakra.
Kakuzu: In terms of experience, Kakuzu has the most in the Narutoverse. Not one individual has more battle experience. He's from the same generation as Hashirama when you compare his age with Hiruzen's. More importantly, he has access to a wide range of high damage jutsu that he can spam.... Naruto would have to expend more chakra to get close to him. Doton: Domu would counter Naruto's corrosive body, so Kakuzu actually can punch Naruto. Between five masks, tendrils, and the combat skill to outmaneuver a veteran shinobi WITH a sharingan.... Kakuzu.
Itachi: Between his overall better combat intellect, the Totsuka Blade, and the Yata mirror... I don't see him losing to Naruto at this level.
Pain/Nagato:...... as you yourself noted.... they wreck.
Obito: You're assuming that Obito would fall and get himself cut in half while becoming tangible once more?! Hardly. This is the same guy who was dodging out of nowhere attacks from Gai and Kakashi.... there's no way he's getting himself caught by Naruto. Hell he can even throw out Izanagi if he HAD to. Also, he had a plethora of basic strong fire techs, and most importantly he had the Uzumaki sealing chains or whatever that could stop Gyuki.
This argument is basically saying Naruto during his fight with Orochimaru was already in the top 10.... that's a logical fallacy. There's no chance that is possible. Aside from basic storyline arguments saying so... there are too many people we've seen as far stronger.
