Not one character has completely Surpassed Orochimaru
The simplest explanation for this would probably be that, apparently, no matter what you do to him, Orochimaru Apparently, no matter what you do to him, Orochimaru simply refuses to permanently die. He has been alive since before Hashirama died, and throughout that time, encountered the most powerful Shinobi to ever live. He perfected the most powerful technique in existence, (if you can name a better technique than Edo Tensei, be my guest) and knows arguably more than anyone else in the NV.
He may not have die, but yes he was deafeted a lot of times. Itachi solo him with the Tosuko but return from death. Sasuke solo him but again return, Tsukuyomi solo him hhahah but again was safe by the duo yaoi. A lot of people can defeat him, he may not die easy because he has forms to return but that doesnt mean win cant lose because he already have lose.
I hereby challenge you to name a person who has surpassed Orochimaru in.
Intelligence
Skill
Itachi, if he is better than Sasuke, and Orochimaru admitted that Sasuke was better than him then Itachi is far better.
Sasuke
Madara
Jiraiya
Minato
Maybe Hashirama, but i think yes
Al those are more skillful than Orochimaru by far.
Mmm all the perfect sennins has more stamina than him. Minato, Jiraiaya, Naruto, Hashirama, Kabuto, Raikage 3 and 4, Kisame and a lot more. Orochimaru has 3.5-4 stamina in the databook.
Mmm i have not seen a feat of strength of Orochimaru but also has 3.5 in the databook so again, all the perfect sennin mode have more strength than him because you need a strong body for the SM and he couldnt hang the natural energy.
Well it is not that he has great durability, he has good jutsu to stand uo to powerful attacks. But Itachi cut his hand with a kunai. He has great durability but not the best. I think perfect jinchuriki has more, perfect SM has more and the raikages 3 and 4 have more.
I think that Jiraiya has more versatility. And yes, he is versatil, like Minato, Tobirama, Jiraiya, Hashirama. Those are the most varsatility ninjas.
And if you were wondering, I do believe that Orochimaru would beat DSM Kabuto in a 1V1.
I also think that, Kabuto is overestimate
