Most relevant and developed characters

[BigGuns Reloaded]

You don't seem to understand bruh. True Oro was the main villain in Part -1, but when I see the Manga's main story, I see his contribution in shaping Sasuke physically (not mentally even , that Itachi does). So yes his character was awesome , but it doesn't add too much in the whole scheme of things. Kabuto's feat is just that : a feat. His actual STORY does not affect the story. See on the list I have mentioned Tobirama above Hashirama. Its because Tobirama had more importance in Madara's character shaping than Hashirama did

Without oro sasuke would've stayed making him much weaker than itachi and naruto
This gives naruto no real goal and stuns his development he would be pt1 just older

Oro also taught kabuto who was most of the bad guys strength 26 edos

Oro also brought back the hokage which was the good guys trump

No oro no development in serval instances

As far as oro goes he could've developed more but he is perfect as he is he is a scientist that enloys observing
