BM Naruto is absolutely obliterated by Hashirama due to wood dragon. Naruto isn't above Sasuke either. I would out Kabuto above BM Minato as well, as KCM and BM speed feats are literally the same, and we all saw how terrible Minato performed on the battlefield, where Sasuke was always much faster than him and so was Tobirama. For shame!
My list:
1-Kaguya.
2-JJ Madara with Shinju absorbed.
3-Rinnegan Sasuke (throw in the blond turd here as well; maybe).
4-JJ Obito.
5-Hashirama.
6- Nagato.
7-Kabuto (the bottom ones have zero defense for IT and WD).
8- BM Bee.
9- BM Minato.
The rest are irrelevant. Kakashi's 5 seconds worth of ability doesn't count. 8th Gates Gai is an iffy one as well. If he doesn't start in that gate, the loses to everyone on the list and even several others.
Ok I'm sure by ET you mean Sound 4 but even then no. Itachi was going to take down Kabuto on his own and the fight only dragged on as it did because of Sasuke's presence. Nothing else was stopping Itachi from using Izanami at the beginning. How does Kabuto even get above a BM Minato?
Eh, no? Itachi was nearly done more than once when Sasuke came to his rescue. He needed time to prep it. Without Sasuke, he never would have accomplished it.
