Because that's the only thing that makes them worthy of being in some lists lol. No but to be honest, Kabuto is strong, even without Edo Tensei, but Orochimaru isn't in my opinion.Why is it always the Oro/Kabuto fans getting butthurt over people excluding Edo Tensei?
Yeah I figured that you'd say that, she is a tier above him if we talk about the chakra section. Even Naruto and Sasuke held their own against her.Manga already stated, implied, and showed us that Kaguya is a tier above Madara. Lets not deny manga facts now.
By raw power yeah, by the way, he never fought HER he fought Juubi with her inside him. So probably a whole other fighing style and techniques.Rikudo already said she's stronger. Don't know why you are doubting anything.
This whole area is all types of messed up.
How will Naruto and Sasuke individually defeat the intangible duo (individually) except if Obito's chakra doesn't last that long, but I doubt that.-Obito and Kakashi aren't above Naruto and Sasuke, not a chance in hell. Gai isn't on Sasuke or Naruto's level at this point either.
About Gai: I didn't put him above Naruto, because of the black orbs. With his speed and power, he defeats Sasuke and he would defeat Naruto too if it wasn't for his orbs.
No Kabuto? No Nagato? Yet you put Itachi here? Even Alive Minato and Tobirama would defeat him.
Itachi already defeated Kabuto and Nagato. that he cancelled Chibaku Tensei with Naruto and Bee's help doesn't mean he couldn't do it himself. if you and me were standing in front of a bear, even if you were the strongest guy in the world, I bet you wouldn't say: "Hey wait, let me take my shot first before jumping in!".
Having said that, what else can Nagato use to defeat Itachi? itachi is smarter, and he would win (again).
Same goes for Kabuto. He's strong but Itachi seals him if he can't defeat him with other strategies. I think you may start about the flute of Tayuya, but again: Itachi and Sasuke needed to get free from the genjutsu as fast as possible, the way to do that was to use genjutsu on each other. Even Shikamaru broke free from Tayuya's Genjutsu. If itachi would fight Kabuto alone, he would've used other strategies to break free from it.
